Good morning. My 2TB WD Caviar Green started reporting problems some time ago. After research I discovered I had the green bug related to the 8 seconds of inactivity before the disk parks its heads. I changed it to 300 secs and so far (4 days) SMART is not reporting any new "Reallocated_Sector_Ct" beyond the 1265 already had, and "Load_Cycle_Count" is increasing at a far slower rate than before after accumulating over 20.000. So I think the disk is fine. Not much data damaged.
The problem is, it's performing terribly slow. I presume that is because the error condition still reported by SMART as:
"SMART overall-health self-assessment test result: FAILED!
Drive failure expected in less than 24 hours. SAVE ALL DATA."
and
"5 Reallocated_Sector_Ct 0x0033 133 133 140 Pre-fail Always FAILING_NOW 1265"
I contacted WD and they didn't help. I understand the legals and morals behind erasing SMART and difficulties to do if for WD disks contrary to Seagate ones.
I think it's perfectly safe to keep on using it, and I plan to monitor SMART quite often so as to make sure of it, but:

Is there anything I can do for my disk to start performing at a speed somehow normal?

Thanks a big lot for any help.

Your drive is failing already.

Overflow of G-list.
Try to backup your data ASAP.

Unfortunately, no. Replace

Thanks for your reply, unknown, but that failure was artificially produced by the bug I described, you're surely aware of. It's not a "normal usage" condition. The disk is now fine, it's just performing slow and that's my question. Anyone?

Can you post a S.M.A.R.T report ?
Did you scan the drive with MHDD, Victoria or similar software ?

As I said before Reallocated_Sector_Ct stopped at 1265 after the change I did using WDIDLE3 to the 8 seconds IDLE parameter, and Load_Cycle_Count reduced its rate dramatically now.
Thanks.

I have scanned the drive only with chkdsk/r as it is NTFS formatted. It fixed only a few clusters on 3 files. I'll try to do one with MHDD. I already posted SMART report, it's awaiting for review before being posted.

running chkdsk on suspected drive is not good idea, if it contains important data.
since this is WD, common slow responding could be the problem, need to diagnose disk thoroughly.

Sorry, I don't understand what you mean by "slow responding could be the problem". I imagine slow responding is a symptom, not a problem itself. Could you explain please?
I'm trying to use MHDD but it reports ERR in red and BUSY in green (I even tried with a very healthy disk, same indicators). In the list of PORTS it doesn't show any device by name or description, just "Port 100h secondary controller" and "Port 170h (PC-3000 board)" (between the brackets is just empty, no details at all), pressing F2 reports "Drive is not ready".
The documentation says "When you see ERROR flag (ERR) you can look at the error register where you can see what kind of error happened." but it doesn't explain where that "error register" is located so as to check it.

Maybe I can help to clarify this situation. The drive had a glitch causing it to park and unpark the heads a lot. This most likely caused re-allocated sectors because it damaged the platters with all the unnecessary activity. The drive being slow now is likely due to an over grown G-list which is causing it to hang.

Slow responding (while being a symptom) is also a term for the "slow responding glitch" caused in WD drives with an over grown G-list. This glitch can be fixed, but the drive is undoubtedly damaged and will likely fail sooner than later.

Back up the data, scrap the drive, and buy another.

Thanks, you did. But rather than buying a new one, I'd complain to WD as this was caused by a defective software programming on their side, they SHOULD be made full responsible for this defect.

Can you please point me in the right direction as to try and fix this grown G-list glitch? Not the full details, just enough to get me started. The drive is not very old and it's very expensive to buy a new one. Perhaps I can still use it with caution if I manage to speed it up a bit.
Thanks.

You can lead a horse to water but you can't make it drink.

If you persist, what data is still accessible will soon be inaccessible because of worsening platter damage, or the drive will need new heads. New heads will cost considerably more than a new drive.

My advice: back up your data now, buy a new drive, and hold onto the current drive as a back-up that you hope will never be required should the new drive also fail. No data recovery specialist is going to recommend continued use of this drive.

I don't use any, but I can download and learn to use whatever necessary. Been trying MHDD but earlier I reported I couldn't make it work as it shows ERR and BUSY indicators even for healthy drives.

LarrySabo, I understand your point and appreciate your advice, but I suspect the damage to the platters won't continue as I already solved what caused it and SMART is not reporting any further damage. I'm only trying to solve the issue with the speed to see if I can have a healthy disk with only a few sectors missing as to use carefully but otherwise normally.

@Merca, if you insist on using this HDD, then I would suggest cleaning the HDA contacts.
