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?
I dont know how it this problem arose
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
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
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.
My drive supports SMART but I dont know why test is unavailable.
