Bad sectors (C5, C6 SMART values)

[Bellzemos]

Hello!

I have an old IBM Thinkpad laptop with a 40 GB PATA HDD which shows SMART values C5: 65052 and C6: 4. It's been like that for a long time, about 2 years - the laptop is used daily and works perfectly.

My friend has a desktop with 1 TB HDD which was giving him problem, he couldn't boot into Windows etc., then he could again after running chkdsk etc. His SMART data shows only C6: 4.

So is there some rule why one HDD would be working fine and the other not even though it shows the same SATA value of C6? Should he replace the HDD?

Thanx!

can you upload the full s.m.a.r.t status of the drive here so some can point you to the right direction.

Maybe this will help.

Thanx but it doesn't really tell me why one HDD works fine despite the corrupted secotrs and the other one doesn't.

Probably not only checking SMART can give you the answer.
Have you done a surface scan?

[Bellzemos]

No, I haven't. Which program would you recommend for the surface scan?

[Bellzemos]

OK, I have used the MHDD before. What about the HDDScan (freeware)? Or the Windows' built-in ScanDisk (chkdsk)? Are those OK?

HDDScan, Vitoria... That will work too.
