At the next address you will find software that promise it can remove bad sectors.

Shouldn't it be still under warranty? If it is, bring it in to change for a new one. Else, you can do a zero-fill.

Forget the fix attempt.  Its still fairly brand new, return it for a replacement.  Its obviosuly still under warranty as knife states.... don't bother playing around with it and holding on to it longer than you have to before the warranty expires..

This is not a big deal as you describe so far. What probably happened was that the system was trying to update a file and update the pointer to the file(s), and it was interrupted.  So that you know, a computer can be said to do multiple tings at a time, but in case like this it is linear, only one operation at a time. This is why many people say to leave system idle awhile, then use the menus to shut down system. When the system is just shut off, or there is electrical interruption (power), this situation can result. That is what programs like chkdsk and scandisk are about, is to hunt down this kind of a problem and apply a fix if they can.

Now if you get a real bad sector, that cannot be written to properly, there is no recovery. It is normal, since the HD has moving parts and not all people can keep their computer perfectly still. A vibration or malfunction can cause a head crash. Possibly the media is not perfect. But trust me, no product can repair it. Once it is flaky, sometimes working, sometimes not, it is best to never use that sector again. The fix is to redo the magnetic coating on the platters, and it is cheaper by far to buy a new HD than to try to recoat the surfaces.

So for one single sector, do not be concerned. But if you end up with a substantial number of sectors bad, such that the available disk space is noticeably diminished, then for sure that would be a lemon (bad manufacturing) and worth the trade on the warranty.

Hi quantumsby,

You may want to check out Spinrite from:
http://grc.com/spinrite.htm

The cost is a bit high (About $90-US), but it will tell you with absolute certainty how bad your drive is.

Also, it only supports FAT or FAT32 formatted drives. So if your drive is formatted differently, you would have to reformat it as FAT/FAT32 to use Spinrite.

stop trying to fix bad sectors/blocks if your drive is still new. I had a 20GB Barracuda bout a year ago.. after I discovered the very first bad sector.. everything else that happens a month later was nightmares. You could try the above solutions if your drive is not under warranty, otherwise just get them to replace you with a new one.

The sector may be "bad" but its not necessarily physically damaged.  Many of these errors can be corrected through software (and/or formatting the disc).  You probably have a corrupted sector, but its not physically damaged.  Download Seagate's "Seatools" to diagnose your disk from a DOS environment (from a bootable floppy):
http://download.seagate.com/seatools/registration.nsf/eula/desktop

Have it perform a thorough scan of the drive.  Scandisk can generally recover the bad sector (and any data there) and mark it bad; but in reality it may not be damaged.  I don't know that its time to call for warranty replacement just yet (especially as you will almost certainly *NOT* receive a brand-new drive as replacement, but a "refurbished" unit that is "almost new")

goto the hard drive web site http://www.seagate.com/support/seatools/ if it has an option to rewrite zeros to the hard drive do it this will get rid of any bad sector if not email seagate and ask for the program to write zeros to the drive ,you will lose all info on the drive and have to reinstall windows

Yes. Go get a brand new harddisk replaced. Its not worth the trouble since you have the hardware warranty valid.

*echoes back too* ^__^

Its still a link to Seagate, and its still the SeaTools program.  My link goes direct to the page that once you click "I agree" the file starts downloading, and no need to choose which one as they have 3 options on the general "SeaTools" page.

dogztar i don,t know what the real problem is since i posted a link to the tools page outlineing its function and you posted a direct download, bad advice if someone does,nt know how to use it keep smiling

Kyle SchroederEndpoint EngineerCommented:
Hmm, well I don't see where it tells you how to use SeaTools on your link...the "Learn More" doesn't say what to do.  Its pretty straightforward if its anything like other hd diags out there...
