In the current period, I have a feeling that I will see far more failed Seagate Momentus HDDs than Toshiba HDDs!

I likely had to condemn two Seagate Momentus HDDs already! (even when not sure if I did or not)

That one makes me suspect a shit HDD board or a shit component on the HDD board.

Default Re: The hard drive failure thread

well... over the weekend, i performed some read and write tests on the caviar black 2tb. i first used the write lba numbers test in victoria which writes date and time stamp data on the drive's sectors as well and the write operation over the entire drive went fine and the drive did not reallocate any sectors.

the drive seems to be still in perfect health aside from the raw read error rate, most likely racked up from trying to constantly re-read bad sector data during the drive recovery operation with gnu ddrescue in linux.

been reading and verifying the sectors on the drive and no errors. tried re-writing the lba numbers again with different date and time stamps again and still no issues. not sure what happened to the drive on that day to cause it to crap out... maybe the psu was unstable on that day as i noticed on the pc health status screen in the mobo bios setup screen that the 12v rail was only 11.4v. could be unstable power causing the drive to crap out esp. when writing data and malfunction. when power was stable again, the data written to the drive was stable and fine thus it seems to work again. could be a dirty sata power connector or bad psu modular cables making intermittent contact.

i also hadnt used that system for several months, so it could be that the jp-ce turd caps in the enermax liberty 500w degraded while sitting unenergized. when power was applied, the caps were able to reform but not without providing degraded filtering performance for a short while which caused unstable power. my enermax liberty has white silicone glue not the brown conductive one so its not stuff getting shorted inside the psu making the power unstable.

since it seems to be working fine now, i guess i'll put it back into service by cloning all the data off the hitachi 2tb drive i rescued the data to back to the cav black 2tb drive. i guess this is another cautionary tale not to use junk psus with modern hard drives. guess i should stop using that enermax liberty until i get rid of those jp-ce turd caps...

11.4V is -5%. Note that the DISK (and controller) really only care about what the supplies are LOCALLY, not "someplace else".

# cmp /dev/rawdevicesource /dev/rawdevicedestination
neither should throw ANY errors. And, should hammer on the drive pretty hard (though all sequential accesses).

No, that's not how PSUs and power work at all!

For starters... NEVER trust the motherboard voltage sensors - at least for the ones that directly measure the PSU's rails. The only voltage sensor I somewhat trust are the CPU V_core... and even then, I always double-check it with a multimeter. On that note, it's worthwhile to mention that crappy/cheap meters can also show garbage readings. Using two of my cheapo HFT meters to check the 5VSB on an Antec PSU I was fixing... one read 4.75V and the other 5.15V. So is the voltage on the 5VSB high or low? I then took my "more serious" Radio Shack DMM and checked with it - the 5VSB was 4.99 to 5V right on the spot. I proceeded to confirm the HFT meters were showing garbage by using a known 2.5V and 5V reference voltage source.

Also bad power isn't going to necessarily result in high Raw Read Error Rate. If anything, I think that's just due to the fact that you have a WD Green drive, which are known for their problems / bad reliability issues.

More to the point: I'd lift the PCB from the drive and check the head-amp / actuator arm pads on the board. On WD drives, they are known to tarnish / oxidize after some time due to bad/cheap tinning of the PCB. This goes as far back as the first WD SATA HDDs and even affects some of their IDE HDDs close to the beginning of RoHS era. So when I get an old WD drive, I always pull the PCB now, clean the head amp PCB pads, and often even tin them with Leaded solder. They'll never tarnish again afterwards. Also managed to revive two old WD SATA HDDs that way when they weren't showing up in BIOS at all and clicking/seeking like mad.

Good theory, but no. A few months in storage is not really a big deal for caps. If the caps failed in that time... it means they are either crap and were probably going to fail anyways. Either way, they can't get "better" afterwards. So the whole thing "HDD was unstable before but is stable now" likely has nothing to do with the PSU power.

On that note... the tan/brown "conductive" glue doesn't cause intermittent problems either. It is only dangerous on the primary side (and sometimes very rarely on the secondary side), where after some time it will become conductive enough to mess up driving signals in the PSU... or worse, bias a MOSFET Gate when it shouldn't be and cause a major kaboom. Either way, both of these cases will directly result in a non-working PSU, not a "was bad before, is OK now" scenario.

I wouldn't call that Enermax PSU junk. Granted the PCE caps in there are pretty old and probably are due for a change now... but I still find it highly unlikely this was the cause of your HDD malfunctioning.

I recently tried similar with a WD2500JD

Went from:
CLACK----CLACK----CLACK----CLACK

To:
clack-clack-clack-clack-clack-clack

Used Deoxit Red (on overnight) then Deoxit Gold

Didn't think of tinning though - hmmm, has joined list of stuff to try

Oh, I have one of those as well. This was one of the WD HDDs on which cleaning the contacts did *not* work (HDD still clicked the same afterwards.)

So tinning the pads will by no means revive every bad WD HDD back. But it's one less thing to fail (and still worth a shot if nothing else works), so that's why I do it.

To remove the Deoxit, I cleaned the pads with a typist's eraser pencil (from back in the day), then tinned them with 60/40, finally removing excess solder with Chemtools wick

Wasn't that optimistic, but pleasantly surprised to hear Bzzzt heads loading noise instead of clack-clack... with drive being detected by BIOS

Then went through WD Data Lifeguard Full Scan, Full Erase and Full Scan again without missing a beat

Finally put it in a HP dc7800 to use instead of a bigger drive, and left it installing Win7

Came back to the screen for entering user & machine names and after entering something, CLACK---zhzhzh---CLACK---zhzhzh... instead of cleanly coming out of sleep mode

Damn thing - <7200 hours on it

Well, at least it "lived" for a bit longer. Perhaps the full scan + full erase was too much for it? IIRC, those particular drives tend to run hot - especially in an enclosure. Not sure if that plays a part or not.

Also, it's interesting to note that, based on your description, the drive is still trying to power on / calibrate but fails somewhere halfway there? On that note, I wonder if putting it in different orientation will do anything. Just makes me wonder if the brief amount of time you got it working was a coincidence or really a result of cleaning the pads. Could be that the HDD was just intermittent before too??

I had put it aside with a note saying undependable

Anyway, while walking dog, I thought about differences between my testing setup and the dc7800 - namely IDE vs AHCI

So I changed the dc7800 to IDE and did another full scan, which came up clean

Then I continued to set up triple boot - XP, Win7 & MXlinux - which all went well, although I was nearby, not letting it go to sleep

I did Google "WD2500JD sleep problems" and "WD2500JD ahci problems" in case of a firmware update, without finding anything

Does pic look like a drive with problems?

Not at all. Looks pretty clean, actually.

Only "unclean" value I see is Ultra DMA CRC Error Count, which typically results from a bad SATA/IDE cable or bad PCB contacts with the headstack / head amps. But since bad SATA cable is unlikely to be the issue and since you also already fixed (tinned) the PCB contacts, most likely any value left in the UDMA CRC Error Count is from before, when the drive had the dirty/tarnished PCB contacts. IIRC, UDMA CRC Error Count can never be reset, even after zero filling. So probably nothing to worry about.... but do watch it. If the UDMA CRC Error Count keeps going up, the drive likely still has problems with the PCB contacts or possibly the headstack itself.

I had one of a similar model, if not the same model and in 2003 or the forth quarter of 2002, fails with a click of death, if you try to go beyond 238 MB.
