Pending sectors

post #1 of 7
Thread Starter 
Hi,

My system drive has a pending sector count of 17, and offline uncorrectable sector count is 1. These values have stayed the same for about 5 months now. The HD is about 2½ years old.

In practical terms, the drive works just fine, although there are some unreadable files (detected by backup tool). I plan to use it as my system drive until the condition drops to the point where it starts causing actual problems in everyday usage.

How long would you guess the drive is going to last? HD Sentinel says 490 days, but recommends to continously monitor the disk status. Should I consider a full format to see if that fixes some of the problems?

If it's starting to fail on a portion of the drive the failure will spread within a few weeks.

I'd run a Seatools for DOS scan against the drive and partition around any section that exhibits errors or hangs. You also might want to do a chkdsk C: /r from within Windows.

Keep in mind if the failure is indeed within the drive itself, any procedure outside of replacing the drive is merely a stopgap solution.

keep an eye on that thing. just fyi, 1 sector = 64bytes, so its really not that much. reformating may actually make things worse. just backup that thing at least twice a week from now on.

You can run the SpinRite .iso on level 4 to find and correct any errors. There is no better tool for the job. Then do a full system imaging to a new drive. This is the best way to handle a drive in your condition. It is beginning to lose it's ability to hold 1's and 0's. That is never a good thing.

So if I want to try and fix the corrupted files, should I use checkdisk or spinrite? How long will the process take?

Use Spinrite. Depending on how many bad sectors it needs to fix, SpinRite can take from 4 hours to a few days to run through completely. I am not quite certain because I have never used it on a TB drive before, and size does make a difference since it fixes data bit by bit, no matter what the file system. There is no program like it out there. I have run it on a few drives and gotten a good 6 months out of them before I needed to do it again or the drive totally crapped out.

I agree. I would run SpinRite on it to try to get some more useful life out of it, but your drive is beginning to show signs of age, and it will likely fail sometime in the next few weeks or months. Now would be a good time to check its warranty status.
