what the hell is at the end of that hexidecimal?

Do a virus check just incase, then defrag and chkdsk the hell out of it. :p
 
Im not convinced thats anything to worry about, Ive ran ChkDisk before and nothing seems out of the ordinary apart from the reported bad sectors. It says 8kb in bad clusters, thats less than a 100th [correction] of a megabyte.

I know I just like to be safe. But you wouldn't be asking if you weren't worried though. ;)

Less than 100th of a megabyte! It's normal to get bad sectors - your HDD learns where they are and knows not to use them again - no biggy.
 
The answer I was looking for was if this behavior (bad clusters) is indicative of impending hardware failure.

I ran checkdisk and it took about 2hrs so you can see that spamming chkdisk is hardly the first option I would consider.

Also is there a program to heal these bad clusters?
 
Would suggest running the Hard Drive manufacturers testing software from DOS, should tell you what the problem is and then by e-mailing them, seeing if it's serious enough for a RMA.

Backup first though! As it may attempt to fix the problems and in the process, destroy data. Although it's unlikely, better safe than sorry!

Bad clusters are actually unusable memory located on the hard-disk and the OS knows not to write on it. Bad clusters are physical problems!

OK, thx. I've done this before just needed jogging my memory.

This is an option, I have enough space to backup on my new caviar green 1Tb.
 
Back up all your data. As it is only 8KB.

Btw 8KB is actually 1000th of a megabyte. :p

1000 000/ 10 000 = 100 fail:rolleyes: (rounded 8kb to 10kb)
 
You can still use that drive, just remember not to store CLASS-S IMPORTANT DATA on it. If you know what I mean. .exe files for games and that will be alright, store the saves like you did in that external or other drive you were on about. Hope I helped dude. :)

That's not really true. Bad sectors are a physical problem with the hard drive, and there's no way to get rid of them. Hard drives have some spare capacity, and the drive's controller is able to 'learn' where bad sectors are on the drive, and remap logical sectors so that reads and writes are directed away from the bad sector towards a good area of the drive.

This normally happens completely transparently, so it's quite rare that it's picked up by the OS. It might mean that the drive has run out of 'spare' sectors to remap, which suggests to me that you shouldn't use the drive for anything you really don't want to lose.

Either way, formatting will not solve it. In fact, the only difference between a quick format and a full format is that a full format goes through the drive and marks bad sectors as unusable from the beginning.
 
Didn't you read the rest of the thread Mattus? :S I've said all you've said... he's backed up his data and I said don't use important data on it...
 
You obviously haven't read my post very carefully. You said that formatting removes bad sectors, which isn't true. I thought I'd explain that so that nobody coming across the thread thinks that formatting will rescue a bad drive and ends up losing data!
