HDD Bad Sectors?

[Meridianox]

Hi, I'm running a desktop dual booting Win7 with Ubuntu 9.10. The main hard drive is fine, but I have a second empty drive in a single NTFS partition. Ubuntu on boot reports that this second drive is failing, in Disk Utility, it reports,

DISK HAS MANY BAD SECTORS - Reallocated Sector Count - Count of remapped sectors. When the hard drive finds a read/write/verification error, it marks the sector as "reallocated" and transfers data to a special reserved area (spare area). 55 sectors.

I've also ran CHKDSK (chkdsk /R z: ) in Windows as well as SeaTools (Seagate hard drive diagnostics software), but neither of these can find anything wrong with the hard drive.

C:\Windows\system32>chkdsk /R z:
The type of the file system is NTFS.
Volume label is Files.

Question is, does Disk Utility know something that CHKDSK doesn't and is there something actually wrong with the hard drive (and I should get it replaced by the manufacturer)? Or is Ubuntu just being silly? Any other things to test and verify?

Thanks.

Mine on my laptop did the same, it wouldn't install 9.10, as this was a refirb laptop I thought maybe that was the issue, so I picked up a Faster HD and put it in, works great. Maybe it was bad, maybe it wasn't but for 60 bux it was an easy cheap fix.

And now I have a new HD and don't have to worry about it...

The new disk utility, Palimpsest, is simply reading data from smartctl, which is a utility that reads diagnostic information stored in the drive itself.

Sometimes the figures are out of line with what's really going on and need a correction factor applied, but smartctl and Palimpsest don't know that. Sometimes, I suspect that drives may already be on the way out but haven't done anything terrible yet - or maybe there have been some glitches that have been blamed on software.

If you are at all unsure, do regular backups. Even if you are confident the disk is OK, do regular backups. That way, you are covered.
