Bad sectors on HDD won't go away!

  ukzz4iroc 08:55 22 Aug 2005

Hi all,

The problem is when I try and run CHKDSK. If I use option 1, everything is cool. If I try and run option 2, attempt recovery of bad sectors, all hell breaks loose. This is usually in the form of a system freeze on Phase 4. If I check both options on CHKDSK and reboot, it will get to step 4 and reboot and repeat...

After running the basic chkdsk, on its report after it says that 274kb files in bad sector (amongst other things)

If I try and run Diskeeper, it gets to 35% through and then I get the dark blue screen of death and it tells me it is going to memory dump??

The strange thing is that all applications work fine, although Zone Alarm forgot all its settings at one stage. Have run Spyware Doc., Microsoft AS, Ad Aware, Spybot and AVG and nothing found. All games still work fine and internet is fine. The only way you would know there is a problem is if you try and recover those bad sectors... It also means I can't defrag.

Any ideas?

What make is the hard drive?

It would be a good idea to go to the makerd website to see if they have a diagnostc program for the drive as it may be failing.

Yes - your hard drive has a problem. Do as AndySD says and get the drive manufacturers diagnostics.

Backup all you can right away - and beware that some of the diagnostics will destroy all the data on your drive

Try scandisk, that is the utility needed when windows says your drive is developing bad sectors and you need to recover them

except that if your OS is Windows XP then you don't have Scandisk but have ChkDsk instead which you are already using. Other than that I agree with all that's been said.

Sometime in the past, could even be when the HDD was first formatted, it was checked for errors. Any place on the disk that the checking program had trouble reading back what it had written, was 'Marked' as 'Bad', thus preventing future use.

In fact, early hard drives, (when they first became available), were usually pre-formatted, and quite often had 'Bad Sectors' locked out, and identified on the label stuck onto it !

1> If your disk has bad sectors since it was formatted, how did data you want get into those areas ?

2> If your disk is developing bad sectors in areas where you have data you need to keep, then the drive is dying i'm afraid to say and needs to be replaced pdq.

3> If you don't have any data in Bad Sectors you need, then don't try and recover them to gain HDD space. They were troublesome in the past, they won't get better.

4> If you have data to recover from a 'dying' HDD, then there are specialist companies who can do this from disk drives that have been run over by a tank (thats a joke by the way, but you get the idea), but this process can be expensive.

Thanks for the help guys. The bad sectors appear to be in areas I don't need- the problem is that I can never do a defrag now. Data seems to be releatively stable for the time being though.

Have ordered a 120GB Maxtor 9 I guess it was time to upgrade anyway. I will use the old drive as slave to get all my files across then reformat it. Anyone have any pointers on this.

One other valid point is that the original drive was FAt32 and recently converted to NFTS (can't remember ackronym)within the last week. FYI it was/is a 60GB Seagate.

it used to be the case that bad sectors were always moved to the end of the drive, as such you could partition the bad sectors off, leave that unpartitoned and windows would not show that area, you could then scandisk, chkdsk whatever.

not sure if its the same now but i would imagine it is.

septembers edition of Computer Shopper (sorry FE)

carries paragon partition manager full program. with that you could partition off the bad blocks without damage to your existing files, just take care. its a bit of a guessing game about how much of the drive is useless but i would reduce by about 10% to start with, then try a defrag or checkdisk and if you still have problems, make the dead partition even bigger. simple maths might apply, if you have a 20 gig drive and only 8 gig of data then just reduce the drive by 50%, do your disk check and when you get the new drive, swap your data then remove the old drive (it might start to affect your pc if it is on its way out).

good luck.

"it used to be the case that bad sectors were always moved to the end of the drive,"

I always thought Bad Sectors where physically bad areas so how can you move them to the end of the drive?
