Bad sector

[bagavan]

I checked for my external HD for bad sectors by HD tune PRO it displayed 47 bad sectors..I was shocked to see this and to verify I checked the disk using default windows tool.I chose scan and attempt recovery of bad sectors and the report showed no problems..Does it really have bad sectors?

 

[bagavan]

I dont know how it this problem arose

 

[bagavan]

No problem..But during high usage it gives slight sound.

Try manufacture's Hardrive Diagnostic tools.
Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.

It passed all tests but was unable to start SMART test as it displayed test is unavailable

Are these the SeaTools tests. Even the long test?
Partition Wizard also has a partition surface test.
If it passes all these I'd be wondering about HD Tune Pro.

You could compare with other software that use SMART parameter:
- Hard Disk Sentinel downloads
- Speccy - System Information - Free Download
- SpeedFan - Access temperature sensor in your computer

YES in seatools It passed the long test.

Due to manufacturing limitations, all mechanical hard drives will have some defective sectors. In normal everyday use, these are unnoticeable because the drive firmware automatically swaps these sectors out and replaces them with a good spare (also known as mapping). However, some disk maintenance/analyser programs work at a deeper level than programs used on a day-to-day basis, and these can sometimes pick these sectors out.

As regards SMART, not all drives support this feature. Most do, but there are still some that don't. It also needs to be enabled in the BIOS.

 

[bagavan]

My drive supports SMART but I dont know why test is unavailable.

 

[Dwarf]

Is it enabled in your BIOS?

 

[bagavan]

Yes

HD Tune has a vested interest in finding disk errors. but i'm sceptical that way.

 

[bagavan]

So there is no problem in it?

 

[kword88]

i would trust windows chkdsk. what problems did you have that made you download HD Tune?

I just googled for hd problem checker and I found that ..So no problems rite?

 

[kword88]

i wouldnt think there is a problem, otherwise windows chkdsk would find and fix it. but since you went to the trouble of searching for such a utility, i assume you are experiencing some sort of problem?

All hard drives have an internal area to which bad sectors are placed via the fimware. If this area becomes full then the OS (chkdsk) will start to see these and this is when problems start to occur. You are not at this stage yet so the drive is still, in my eyes anyway, fine.

I think the 47 bad sectors is in fact a relocation count, those moved to the internal area. As said in an earlier post - many drives come shipped with bad sectors and are placed in this internal buffer, so most people would never know it.

Yes absolutely bad sectors were found in relocation sector count.

You can't do read smart on an external USB drive even if the drive supports it. The drive has to be sata attached.
