There's at least 1457 bad sectors (and growing) - however, they are towards the end of the drive, so I suppose you could format only part of the drive and use only that part. If it never accesses the bad part of the drive... maybe it'll stop? If you zero the drive out and only use the first 50-80%, maybe it'll stop going bad?

I tried that once on a WD Green - my drive died totally a few months later.

I deleted all of files on that hdd and merged partions and new status is here. What do you think ?

It's still got bad sectors - they just moved to Offline Uncorrectable.

Well, go ahead and give it a try - make sure you only partition/format part of the drive, and then you can experiment and report back on how long the drive survives.

Sorry, be posting in a old threat.

My mobile computer started making some noise in the HD.
I searched some sites and found the Crytaldiskinfo and tried it.
It showed the yellow caution warning.
Since that i take it to where i bought it, because my computer is only 1 year of age.
The guy said that need do some tests, and it said my HD is fine, just some correctable sectors got bad, format your computer and install all again it get fixed.

The problem is, i full reinstalled a new windows, and installed my stuff all again. then just to check, i used the Crytaldiskinfo, and i got 3032 current-pending-sector-count, then it increased to 3040.
Now i deleted some stuff and it come back to 3032.

I dont use allot the disk, its a 500gb and i never pass the 150gb.
Im doing my thesis now, im afraid of this stuff. i keep backup dropbox, but if it fails me when im defending my thesis?

If i change the disk on my own i lose guaranty, already passed 1 week and didn't died yet.

Can a 3032 current-pending-sector-count, be fixed?

I tried a windows stuff an week ago to fix bad sectores, my computes stooped at 11% and stayed there all day and night.

thank you.

Hello Nel Miranda.

I'm sorry to be the bearer of the bad news but this HDD is close to completely failing and there is nothing you can do to fix that apart from replacing the drive. You should ask for a warranty replacement HDD. The amount of pending sectors is too big and is a strong indicator of the poor health of the drive. A full format of the drive will force the HDD to reallocate the bad sectors but this won't really fix the problem. Good luck.

Since this thread comes up second in google search, ill ask it here.
I was preparing my PC for sale and ran Recuva, to see whether it was worth wiping it clean, and it borked my drive:mad:

Crystal disk now shows 0A as current pending sector count. How bad is it (guess i cant sell it anymore)?
Zero filling it with Lifeguard tool still viable option?

Thanks in advance.



UPDATE:
HDD appeared to be fine, something went wrong with SMART data. Each session of Win Dlg test tool created new bad blocks and it went from 10 bad blocks to 48 in seconds. Doing only full zero write fixed the problem until i ran next SMART test, which resulted in more bad blocks.
I was able to fix it buy zeroing it with Win Dlg and then doing full format in Windows, followed by third party partition wipe (not entire drive wipe!) Now it passes every test including Hd tune.
Nice work, WD, in tricking me buying another drive

Hi t0tum,

SMART data isn't usually confused. What you are observing here is most probably a result of a problem with the power supply or problem with the HDD heads. I would suggest you test the HDD with WD DLG extended test in a different system if possible. Pending sectors are sectors that cannot be read properly and are marked so the drive can reallocate them the next time they are written to or after the HDD succeeds in reading the data. In this case when the sectors are successfully overwritten when you run the full write zeros. However when you run the SMART check they cannot be read and are again marked as pending. This makes me believe it can be related to a problem with the power supply. If that's the case it's a thing worth checking since the PSU can damage other components in the system .

Could be HDD heads! My point being, i was only able to pass quick, or extended WD test after i partitioned my drive in windows. After two full zero writes WD tests kept failing, producing pending sectors and populating my event viewer with disk errors: The device, \Device\Harddisk1\DR1, has a bad block.

So, in my case, pending sectors were never relocated? Smart now shows 0 pending and 0 relocated.
The only evidence i can find is perhaps this block at the end of disk:

If they were reallocated that should be listed in the SMART data, and it's not. This could happen if the bad sectors are not bad due to degraded media/platter damage, but instead because they weren't written to properly. I would still test the HDD in a different system to confirm the conclusion.

Hi, sorry to invade this thread, but I have a question regarding one of my hard drives:

dcf3e875ffcc43768052ebcb9806feca.png


I have a Current Pending Sector Count of 1, but I'm not sure how long that's been there for since I've never actually checked my hard drives until today.

Should I be concerned? This HDD is fairly old, but it's been reliable since I first had it.

I've already run chkdsk on both partitions associated with the drive, and the checks didn't detect anything out of the ordinary.

Thanks a bunch!

Hello everyone, sorry to drag up this thread once again!

I'm having simlar problems to everyone else here. I have three HDDs two of which are "Caution" on CrystalDiskInfo (shown in the pictures below) just wondering if its worth trying to fix or should I just replace the HDDs?

I have been having BSOD for the past few weeks and suffered simlar issues with my HDDs a year ago but managed to make them behave until now. I use my G: drive to record 1080p game footage to for my YouTube. I'm normally running the game I'm recording off the G: drive also. But sometimes my H: drive.

I've tried switching up which HDD I record to/ record a game from and still get a BSOD normally when I hit "Record" on my recording program (Action Mirillis) or once I've been recording for an hour or so then hit "End recording". Then I get a BSOD a second or two after. So I imagine its when the file is being finished up and wrote to my HDD?

When playing games on my C: G: or H: drive I sometimes hear a beep then my PC freezes for a little bit before returning to normal. The System Event logs is telling me its a DCOM error.

I've ran Norton Disk Doctor scans on all three drives as well as a /f CHKDSK on my C drive last night and when I came back it was at the desktop so I imagine everything went okay?

Not sure what to do, can someone take a look at these pictures and give me your opinion.

Thanks guys!

Hi guys. I have a problem with my hard disk just yesterday.



Do i need to get a new hard disk asap? Its not that important, but I keep all my movies in there. So yea.. xD haa.

Once it dies, I am gone. Will need to redownload 1.7TB of movies and series. At the moment I am not using it, leaving it at idle, and most probably going to upgrade to a 4TB drive.. haha.. Please advise, I have not much space left in the rest of my hard disks to store that 1.7TB of movies for a full erase like I read on this thread.. haha.

Bad sectors are usually representative of physical damage, and are usually progressive.

Since you can't even check this for certain without being able to zero write the entire drive, you should find some way of backing up everything asap.

Okay. But what if I leave it at idle? haha. Cos yesterday I was downloading an anime series and then it appeared System Disk Error. lol. Is the other way to buy a new drive and transfer it all into the new one and scrap this old one? Will any bad sector from the old drive be transferred along?

Leaving it powered down entirely might prolong it's life, but if those pending/reallocated sectors are representative of damage to the media, just keeping the drive spun up can exacerbate the damage.

It probably shouldn't even be plugged in until you are ready to try to move data off of it.

I wont lie your drives are running hot sir 42C? Ouch. Heat degrades drives faster
 
#37 ·
42C is perfectly fine for a HDD.

Temps are only a concern if they are excessively hot (over 50C) or excessively cold (below 30C) 35-40C is nearly ideal for mechanical drives.

I think my 7 year old WD Green 1TB (WD10EADS) is dying. Two weeks ago it had strange long pauses before it showed any files in windows explorer, and now CrystalDiskInfo says it has 897 Current Pending Sectors and 611 Uncorrectable Sectors. I'm backing up the data, but what should I do with it afterwards? With that many bad sectors this thing is unsalvagable right?

Back up your data and replace the hard drive. It is failing and failing badly.
