SSD NOT DETECTED BY BIOS - HANGS

[Goofy_Brained]

New to forum
________________
Been reading this great forum and greatful for clarity and focus.

________________
PROBLEM : The BIOS (seems POST) hangs for 30 seconds (blank with '_' character upper left) then BIOS Splash page hangs for ~60 seconds (Unresponsive to <F2> - enter bios Key stroke until after hang) and does not detect the SSD Hardware.

The BIOS CAN detect the SSD (AFTER ENTERING BIOS & SAVING & DELAYS & REBOOT) and when booted (using PXE or USB-FDD _ DOS) then it can be accessed by and operates normally (eg Fdisk, NTFS DOS commands etc)

The SSD operates fine with USB connector and WinXP(SP3)

______________________
Given PXE_Boot configuration : 945GCLF, PS2 keyboard, SSD, monitor

When hanging occurs, the drive is not recognized/detected by the BIOS... whether entering BIOS or not <F2> and BIOS continues to Bootable Device Not Detected

THIS Remains the cycle regardless of BIOS configurations UNLESS and UNTIL I make a change of ANY parameter in BIOS - whether affecting the SATA/BOOT Priority or NOT.

Then will still get the 30 seconds to Splash/60 sec hang and IF <F2> into BIOS and Drive IS DETECTED.. or IF NO <F2> goes to error message with No Bootable disk (SDD is just formatted and has no OPSYS)

________________
ANTITHESIS

IF I turn off HDD Auto Detect in BIOS takes ~2-5 seconds to splash and ~5 seconds to No Boot Disk found.

IF I unplug the SDD/SATA Signal connector ~2 sec to splash and ~5 sec to Bootable Dev not found.

Repeated have booted with DOS_FDD, with the SSD Drive attached and NO HANGS, and drive was seen in BIOS BOOT settings (was recognized) upon subsequent ctrlAltDel resets, HOWEVER if Power Cycled & reboot then there is hangs until again entering BIOS and some change is Saved
______________

Very Simple Hardware configuration :
> Intel D945GCLF (BIOS 0150 dtd 2009-02)
(same effect with BIOS 0038)
> 2GB ******* memory, PS2 keyboard
> OCZSSD2-1SLD60G Core SSD Drive (64GB) in SATAII port 0
> No Operating System - just BIOS & POST
> SSD partitioned & formated per OCZ Guides using USB
- Single partition
- Offset 64
- Formatted NTFS
- Set Active using Windows XP(pro) Storage manager
> PS2 keyboard (to eliminate any USB?) and VGA Monitor

___
Hardware Checks

I have tried different SATA Connectors, Power Supplies, along with Test & Measurements extraSBC and tried other hardware with the D945GCLF to test that interface's operation and all perform as expected.

It is just the SDD in its present state that causes the hang.

Note: SBC boots fine with formated WD Scorpio SATA II HDD with no operting system.
Note: SBC boots fine with USB (DOS)
Note: SBC boots fine PXE (Bart's NetDos & NetBootDisk - FreeDOS)


Please help me see the gremlin that is besieging me... it may be obvious but I can't see it

Thanks

try sata mode = IDE
take the drive off of sata port 0
try ssd on your last sata port ( gussing thiers probbly only 2 sata ports on that board?)

did you align the drive ? then formatt

think I saw a post about the atom here somewhere try to find it to

I think it should be obvious by now that OCZ has some firmware issues with the Vertex - hence the poll regarding the latest firmware drop.

Even if you get the drive to be recognized you may then experience BSOD issues or the drive just plain disappearing inexplicably. Lucky me, I've experienced them all to date. Of course, there are more than a few up here who have the drive working very well in their setup.

The good news is that the speeds are incredible so if they can iron out the issues this could be my last SSD for quite some time....at least until I buy another laptop in 2 years.

[HDCHOPPER]

ok then please post in the FW 1199 poll please .

[Goofy_Brained]

Thanks HDCHOPPER

** BIOS has essentially separated Sata & IDE but i had tried various IDE setting & modes just in case & NO JOY

** Tried both SATA Port 0 & 1 and on my fourth signal cable & 2nd power cable & tested both extra-SBC platform (at first because I couldn't figure causality thought it was flakey power or power/signal cable)

** aligned & partitioned on WinXP machine using USB port to SSD. Re-read and reviewed my work on alignment and then re-checked partition information from different partition programs and looks good.

** Drive will read/write both in USB mode(WinXP) and SATA on SBC with NTFS DOS.. it is simply that BIOS hang (90 sec!) that is annoying but has been good for my coffee intake and 'outtake' while waiting

** Looked thru those two links and will look to those later but unfortunately my problem seems BIOS related... so I'm not that far yet.

**Planning to do PXE - BART DOS Netboot (working ) and unattended install XP over network. I just wanted to get past this 'quirk' first to be sure (Again the flaky nature made me paranoid.. let alone this new tech and doing a recall to my DOS years for PXE BART & DOS Networkng)

Been working on PXE XP install (EVEN WITH 90 SEC Delays SOME of the time!!) & monitoring the hang conditions (actually more like diverting around this gremlin & hoping it don't bite me in the ___)



SOME OBSERVATIONS OVER THE LAST 10 hours :

It seems that every time the OCZ SSD drive is FINALLY discovered by the BIOS and then is present to whatever opsys/software, THAT IT STAYS present even during opsys soft reset(ctrlaltdel) over and over UNTIL I do a power cycle and then whatever ethereal configuration for the SSD in the BIOS/CMOS that was established - VANISHES and it goes back to 30+60seconds HANGS and NO DRIVE DISCOVERED until I do the BIOS change and save and IF (???) then the drive is back and usable until next Power cycle.

AS WELL there is a kinda converse situation - IF (thru a power cycle) I have lost that ethereal connection for the SSD - then there are conditions (unknown) when I can even do the magic change/save BIOS and the drive WILL NOT be discovered BUT ALSO DURING THIS TIME THERE IS NO HANG. AND during THIS 'machine state' is maintained over and over - as if the drive is no longer physically connected. (( AGAIN there IS NO HANG when the drive's SATA signal connector is physically removed and power reapplied. ))

The above is one of reasons I WAS SO CONFUSED & FRUSTRATED with hardware & wiring until I figured this out.

I have verified that when this 'machine state' occurs that a power cycle and then the 30+60 hangs - BUT then the SSD is (usually) BACK in the BIOS display on (CtrlAltDel & <F2> enter bios) but of course the BOOT order is now with the SSD on top of the list... and cause the smaller delay of no bootable device (which I would be willing to live with for the few times I will be installing)

AGAIN I am concerned with some flakiness after i've installed. But also the 90 seconds per retry and the UNKNOWN procedure to get SSD visible to the Intel SBC is very distracting the the PXE Install effort. And I have two other SBC's to deal with next.


There are other inconsistencies but it is 6AM and Im getting diminishing returns - just wanted to put more of this out there.


NEXT :
1) Format SSD without offset and check for hangs.
2) Perform partition & offset operations in DOS and check for hangs.
3) IF STILL hanging try to complete a windows XP install and check for hangs.

[Goofy_Brained]

I have found the machine state that is Triggering this condition... Repeatable.

Will be going through combinations of SBC/BIOS/SSD after some needed rest and WILL REPORT... same channel.. later time

So stand down and thanks for your help

[Tony]

I think it should be obvious by now that OCZ has some firmware issues with the Vertex - hence the poll regarding the latest firmware drop.

And why are there issues with the firmware? I created a POLL to norrow down what people are seeing...its not admitting there is an issue at all.

If there was an issue i would have hundreds of people posting and contacting support...its still less than 20 and i feel 90% of those could be cured with a reflash and bios reset.

please do not jump to conclusions...lets see what the POLL tells us. And remember I released shipping FW also so people can always flash back.

[HDCHOPPER]

very well .. yes let us know
btw nice troubleshooting

CONCLUSIONS on OCZ SOLID SSD BIOS HANG and DETECTION FAILURE


MACHINE Consists of :
OCZ SOLID SERIES SSD;
INTEL D945GCLF SBC;
PS/2 Keyboard(nomouse);
VGA Monitor


PROBLEM : OCZ_SOLID_SSD (SATA II ) and Intel D945GCLF CAN Configure to create a BIOS HANG AND SUBSEQUENT NON-DETECTION OF SSD BY BIOS NOR OPERATING SYSTEM FOR DURATION OF DAYS GIVEN CONDITIONS FOR MAINTAINING THIS STATE ARE MET

- Causes total of 90 seconds hang or delay time during BIOS start

- SSD is not detected by BIOS nor Operating systm after this Hang event

- The machine states causing this hang are not easily recognized and these hangs CAN APPEAR to be a very FRUSTRATINGLY RANDOM - NON CAUSAL EVENTS

- Event occurs ONLY under specific MACHINE STATES (including BIOS settings) AND ONLY AFTER specific machine state transitions/precursors (eg BIOS Settings, previous power state, time, next power state)

- ONCE this HANG/MISSED DETECTION of the SSD Event occurs the machine can enter a state that is maintained (even thru power supply off) where in the Event can continue for many frustrating combinations of reset and retries. Machine State causing these events is exited only by a set of specific settings or conditions.

- This State occurs with different versions of the D945GCLF BIOS

- This State DOES NOT occur with other (non SSD) SATA drives under identical conditions to SSD/D945GCLF Hang/NonDetect Events.

- State occurs with another boot device attached
> regardless of boot order
> other boot device enabled or not
(Other Boot hardware devices tested : USB FLash (as HDD or FDD) or USB FDD and PXE Boot)



MACHINE STATE OF CONCERN (Hang & Non-Detection) : This Machine state is summarized by Three Events. These events are seen after a Power Supply Turned On or Reset or BIOS exit > reset.


EVENT 1:
Blank screen with '_' character in upper left hangs for 30seconds
During the Blank screen there is no response to reset button nor power buttons nor any keyboard (eg CtlAltDel) UNTIL AFTER this 30 second Hang when appropriate response occurs <edit> (eg reset/reboot or power off). IF not power off, then reset/reboot Machine re-enters the same blank with '_' character <edit>

AFTER 30 Seconds... enter Event 2

EVENT 2:
BIOS SPLASH hangs for 60 seconds
Code 5A is in lower right corner of screen
During the Splash there is no response to reset button nor power buttons nor keyboard (eg CtlAltDel or <F2> - enter BIOS) UNTIL AFTER this 60 second Hang when appropriate response occurs : doing reset or soft reset or SBC Off or Entering BIOS wherein returns to STATE 1 (except for certain BIOS change conditions or when Power Button is cycled - see Exit Conditions)

After 60 seconds enter Event 3

EVENT 3:
BIOS Exits State 2 hang and starts parsing boot devices. SSD Drive is not detected by BIOS.

Note: IF previously shown in BIOS > Drives is now removed and same with Bootable Devices and boot priority.


IF the SSD is the only bootable devices, BIOS Coninues with error message : No Bootable Devices detected....

During this machine state loop, the SSD is NOT available to any operating system that is booted from an another boot device in BIOS.


MACHINE STATE IS MAINTAINED UNTIL EXIT CONDITIONS MET
Once entered - the Machine maintains this semi stable State wherein Events 1 thru 3 continue as events even thru extra - events such as entering BIOS and resets etc.. This Machine State of hangs and Non Detection of SSD continues until an Exit Condition is met.



VERY BRIEF TEST SUMMARY

OCZ_SOLID_SSD and Intel D945GCLF power on and reset will hang 90seconds & SSD is not detected when under very specific Machine Conditions and Precursor States.

Western Digital HDD's (SATA I&II) DO NOT HANG under SAME Machine States/Precursors as when the SSD Hangs and the WD HDD's (SATA I&II) are ALWAYS detected by the BIOS

This Machine State events of the 90 second Hang & NON-Detection of SSD are a semi-stable loop that requires one of a set of specific conditions to exit

The Hang/detect Machine state continues Until one of the Exit conditions are met

This Machine State makes the SSD unusable for systems requiring restart after a power failure as the machine will enter this state and there will be no drive and D945GCLF will lock up in BIOS Error message or continue with other boot device with SSD not available to required operations. While workarounds could possibly be cobbled together - it defeats the purpose of Commerical and off the shelf for the industrial work.


CONCLUSIONS


CONDITIONS REQUIRED FOR ENTRY INTO THIS MACHINE STATE

TWO BIOS settings ARE REQUIRED to enter this Machine State
- BIOS_POWER_After Power Failure = <Last State>
- BIOS_POWER_After Power Failure = <Always ON>

POWER SUPPLY TURNED OFF while SBC ON (extra-bios - in operating system)

POWER SUPPLY TURNED ON after Long OFF time (tested : >15min but < 2 Hours)


CONDITIONS THAT EXIT THIS MACHINE STATE (while entered into state)

Disconnecting the SDD SATA Signal (while power off) and power on

Entering BIOS, Changing Setting and SAVE and BIOS Reset then Power Supply Off then ON
(any setting but typically change Parallel port ECP/EPP setting)

Power Button OFF for 15sec then ON

Exhibited Exit - but Not Validated : Adding USB Boot Device while PS off then PS on


CONDITIONS THAT DO NOT EXITING MACHINE STATE (while entered into state)

Soft Reset (CtlAltDel)

Reset Button can reduce hang on occasion but SSD may still not be detected

Power Supply Cycling


SUBSET OF CONDITIONS THAT PREVENT ENTRY INTO MACHINE STATE

BIOS Setting BIOS_POWER_After Power Falure = <Always Off>

<add>Other conditions met, but POWER SUPPLY OFF LESS than 15 Minutes THEN ON.. boots normal & drive detected! Must be more than 15min less than 2hours (as far as I took the testing (sorry))<add>


CONDITIONS THAT DO NOT AFFECT ENTRY INTO THIS MACHINE STATE

BIOS Version does not affect the SSD Entering this Machine State
(Tested with D945GCLF BIOS versions 0038,0140,0150)

Partition Offset of the SSD DOES NOT affect entering this Machine State

Other Boot Devices connected - DOES NOT affect entering this Machine State

ALL BUT TWO BIOS settings DO NOT affect entering this Machine State



Hope it helps those of you that know BIOS/Device interactions kind find a solution.


I have spent so much time I am abandoning the OCZ SSD but will watch this thread of couse (I HAVE SO MUCH DATA AND TEST REPORTS IF NEEDED)

The SSD is very much needed for my sealed computer needs, but i do need the power on - sbc on mode... and this use does not envision the operator needed to do a power button cycling .. . just to turn off power (and the SBC) and back on next day...

I am indeed now A VERY Goofy_Brained One after doing these FRUSTRATING and TEDIOUS TESTS !! But I just had to know WTF was going on .. ya know !?


Thanks Again for all your help... I will be sleeping for a couple days now

[HDCHOPPER]

lol have you tried to connect directly to a sata port ? which is the way to do it I would not use the usb method myself
if you must do (partition align & formatt maybe even set active) on another comp then move to your comp.

never got your rig spec. either

[Goofy_Brained]

Hey HDChopper..

___ ON Intitial Checkout of SSD __________________

When I first received the drive I formatted it on my workstating (ASUS P5MT5 WinXP) as NTFS single partition using WinXP Admin Tool>Storage Management. I did some file transfer to/from the workarea on the workstation without issue and even did some cursory speed tests.

I connected the SSD to the D945GCLF (target machine) and also checked file access after booting PXE into DOS and used both NTFSDOS to access some text files (used read only version) with no problem and then checked the partition fdisk.

I had experienced no hangs nor Non-Detected SSD.. it worked easy. (I believe at this time the BIOS POWER Setting was <always off> and I was using the Power BUTTON (NEITHER OF WHICH ALLOWS the hang/no detect condition)


___ ON Partition Offset of SSD __________________

I then sat the SSD aside and moved on to the PXE Install of WinXP (target OPSys for machine).. BUT after reading the OCZ forum, I decided to do the partition offset.

Did the parittion offset on the Asus P5MT-M WinXP computer - used comand window with diskpar -s 5 with the SSD connected via USB port (came up as disk 5, and of course SATA Power and Signal were removed). Again I verified both the offset and non offset versions with both WinXP Admin Storage Management and with wmic.

Note : During a break, I left the USB drive connected after shutdown and there was no hang when I restarted the workstation.

And again SSD & Intel D945GCLF work very fast... IF... the BIOS Setting>POWER Tab>After Power Failure seting = <Always OFF>. WITH Partition offset OR NOT.


___ ON HANG/NON Detect and Partition Offset of SSD __________________

AFTER I had identified the hang as occurring only with the SSD installed.. I did additional testing to see if the Partition Offset was an issue with the Non Detection (more so than the hang).

o Killed the partition/reformated (Workstation USB) and still hang/non Detect would occur
o Tried setting Active or Not and still hang
o SO.. ON the D945GCLF ... under PXE Boot.. and DOS .. re-partition & formatted the drive and still would hang

So I dismissed the partition offset and/or usb formatting/partitioning as an issue with the hanging events

__TESTING DURING HANG/NON Detect and Partition Offset of SSD _______________

Becuase this hanging/non-detection were required for my power on/off - I had to figure out what was causing these hang/non detect events. The events that were STILL SO FRUSTRATINGLY RANDOM ENTRY AND EXIT...

Many times I had to power down and unplug the SSD to get ANY boot device recognized while in "hang/non-detect" state.

During this stage of troubleshooting I tried two different power cables and four different signal cables.

Also I did try SATA signal cables on both Port0 and Port 1

And I HAVE tried EVERY combination of BIOS Setting for drive : Legacy,IDE etc because I have experienced the "magic" that these drive settings can have.

But when I would CHANGE A BIOS SETTING trying to see if it would have an effect and after the change, I would get no change... BUT... IF I then did a power off (and sweep up my hair pulled out) Then, later, upon power on (BUT ONLY IF NOT TOO LONG OFF !!) the machine would boot - with no hang - and the SSD drive recognized!

(( Note too that during a 'hang state' you can Ctrl AltDel or BIOS Enter Save or Bios Enter and No change exit until your fingers break - but the machine will still hang 90 seconds and NO Drive... BUT Simply turn off the power (even though the BIOS change was many steps ago) ...and power back on and no hang and "there's your drive" ))

Later of course, I found out that the BIOS Change/Save was a part (a precursor to a Power Off/On AFTER the change/savet) to this particular Hang State Exit. And once completed.. Power ON... then about 6 seconds to PXE Boot... so fast after waiting 90 seconds over and over you begin to wonder if you just saw.. and indeed... the SSD Drive is Present in both BIOS and Operating SYSTEM! And ALSO... NOW THAT THE HANG STATE IS EXITED you can power off/on and reset and control alt del with NO HANG (until the conditions for ENTERING this HANG STATE are again met)!!! AND YOU THINK ITS SOLVED !?!

________ OTHER RAMBLINGS _______________________________________

BTW... I have scores of test reports where I tried about every combination to fully eliminate and then when I finally hypothesized the State Conditions for Entry and Exit of that Hang/Non Detect state.. I RETESTED against them...


I Really would love to use the OCZ SSD - I have used OCZ Memory for overclocking back to the 90's and have it in my Development and Video Edit workstations where speed and stability is critical ... why I decided to go with OCZ for the SSD.

The SSD works just fine using the Power BUTTON instead of Power Supply. But again... my need is a machine that can be turned off (NO Standby power) and back on when needed - Starting without operator intervention at the hardware.

I have not found this Hang/Non Detect problem with any other HDD nor other storage device.. I am also hopeful this is not an issue with all SSD's.

Thanks for checking in on this.. as if it can be easily fixed then I'll be one very happy camper.

[HDCHOPPER]

kill pwr is always a tough one make shure you dont have hd spindown enabled (when not in use ability)

you can also pwr off via button and once blank screen hit the psu switch a thing I do often copying disk to disk

drives access time is too fast for direct pwr kill I believe but it sounds like you have found a way to do it lol

[dreadlox]

I created a POLL to norrow down what people are seeing...its not admitting there is an issue at all.

But Tony, how are you going to narrow things down with that poll?
It seems impossible when you change the poll after it already started (I voted very early, and after that there were more options added), you have an option "I have no issues" in a poll with the name "poll for those with issues", users can't change their vote if they have systems that appeared to be stable at first, but later failed, etc, etc. And what's with the "I have voted here, please add me to the total amount of people who have voted" - it should be possible to see number of voters automatically, right?

To get some good statistics and get an overview I think you should start over
Create a new poll aimed at ALL Vertex owners (i.e. choose a better subject). Try to get as MANY as possible to vote (i.e. make the poll sticky, and encourage ALL to vote). And try to find better options that will sort things out instead of making it more confusing Now, I have no idea how complex poll you can make in this forum so maybe it's hard. But it should be worth the effort to carefully choose the options to be able to really narrow things down instead of making it more confusing as it seems now.

(from the results in your current poll, I would definitely say it indicates an issue - only 28.38% have voted that they have no issues!! Now, that's probably not true, but it shows that you can make whatever interpretation you want in current poll!)

[Goofy_Brained]

SO THE SSD DOES NOT MEET GREEN/POWER OFF REQUIREMENTS BUT MECHANICAL HDD's DO?

>> Again this is BIOS issues. I have no control over internal wait states except with BIOS Settings (eg Legacy, Native etc).

>> Again NO Operating System is needed for hang - independent of operating system or Not - Just at a BIOS Halt.

>> ALL Power Transistions were Extra-BIOS operations at a BIOS halt condition (error message of one kind or another) or after booting into an OpSys and then idle (but again see #1 above... BIOS Only and still can not be detected.

>> ALSO - the SSD works repeatably with power supply ON/OFF with power supply WITH BIOS Halt OR WITH an OPERATING SYSTEM UNTIL the conditions for a Hang are met. I have cycled 8 times (reset button, ctrl alt del, power cycle - not power button because that resets the hang condition)


>> Again - IF I PUT the BIOS in Always Off Power State - I CAN GET NO HANG ! SSD works Just FINE - BUT NOT FOR MY PURPOSE/NEEDS.

>> I Need the Power State to be Always ON after a power off (GREEN Product,Server, Controller, HDTV, PVR, NAS)

... Remember there are all sorts of 'Green Switches' that now power down the outlets for (PC's, AV equip incl PVRs) - and in so powers them down WHEREEVER THEY ARE. I have no problem meeting that requirement. Powering down and booting back up and in standby is a very common requirement - WesternDigital HDDs, Samsung HDDs both meet that need !! The OCZ_SOLID_SSD DOES NOT MEET THAT REQUIREMENT - at least the one I have.

Yes on MY SOLUTION - as of THIS POSTING _ NOT TO USE The OCZ_SOLID SSD ! I am using a rotating HDD... and altering my environmental - thermal - packaging. BUT... As of today .. I may even be able to USE an SSD. I have contacted 'another' vendor that states they would not have such an issue... I am negotiating...

Thanks for your reply HD Chopper.

Note: Early this AM walked by the test lab and re-verified the BIOS Change/SAVE - Exit & HANG... AND WHILE HANG MODE - did two CtrlAltDel, BIOS Entry & ESCAPE(No SAVE), then Reset and STILL HANGING EACH TIME ! BUT THEN (since I had done the BIOS Change/Save) I did the power cycle and the Hang was gone! I then did power cycle over and over (at BIOS halt) and no hang and very very fast.. did Ctrl Alt Del and reset and again super fast - no problem. But then I've said that before..

Simply put - there is some interaction with SATA II that is NOT the same in the OCZ SSD Controller as in the WD/SAMSUNG SATA Controllers...

And whatever THAT is... the Intel D945GCLF AND NOW ALSO the Intel D201GLY2A SBCs SATA ports and BIOS interact with to hang and not recognize the OCZ SSD !!!

Note that I did some uP programming with Compact Flash as IDE & SPI (as well as a couple other storage media - but no SATA ) and I have interfaced with many differnt controller systems including CAN & SCSI. And from this meager experience I can easily say - ONE OR THE OTHER CONTROLLER (SSD or SBC) is not handshaking properly - WHY THE HANG... and then the continuation of the BIOS after this hang has NO SSD to identify/recognize as it is NOT RESPONSIVE on SATA !?.. BUT ADDITIONALLY - THERE MUST BE A MEMORY STATE somewhere (and my belief is that is MUST BE IN THE SSD!) that is maintaining this state - not Resetting. Again I am NOT AN EXPERT on SATA States - WHY I CAME HERE .. for HELP !? But I AM very good on doing external state machine analysis... and everything ponts to the OCZ_SOLID_SSD as not fully resetting after some BIOS Poll after a power off condition... so I agree about the power down signals.. but then Samsung & WD DO work fine (they both have parking circuitry on power failure and so maintain energized circuitry to that effect long enough after a power failure) AGAIN I HAVE NO Desire to solve the micro issue.. mine is a HDD/SDD that meets the GREEN POWER ON/POWER OFF cycling !

[Goofy_Brained]

I was going to let this thread die after some recent contact with OCZ, however some additional testing should be highlighted.

Further tests (by me) showed the OCZ SSD (only) locked up on another Intel SBC (D201GLY2A) with shorter hang times but the same non-recognition of OCZ Drive.

Further testing (by Intel - GOOD testing & responsiveness) showed the lockup does not occur with THEIR SSD models and the D945GCLF (given the above conditions & states) and with two different bios's just to be thorough. I believe their testing was the same and they understand the issue.

Note: OCZ has dismissed the needs addressed in this thread - for a properly operating SSD under power cycling situations whereas other mfr's (including Intel) seem to understand that designs wherein power cycling can need to be addressed. And regardless of power cycling designs, even so called normal use would face the ever more frequent power interruptions occurring now days where in odd SSD behaviour would be noted by the user, indicating that it would be in OCZ's interest to address this problem from simply a product image and assurance standpoint.
