Bad Sectors

Hello,

My HDD curled over and died last week, I have managed to somewhat recover by running HDD Regenerator over the weekend.

It's a WD 500GB drive, so far I've only scanned 300GB of it but in this 300GB it's found some 3000 Bad Sectors, does anyone know how many bad sectors is acceptable for a useable drive etc, I can't seem to find any statistics.

A replica drive would cost me £50 ($100)

I would say... Zero. If a drive has any bad sectores, it is more likly to fail.

Yeah but once you've run a scan disk it marks the sectors as bad and won't revisit them. Also drives come with x sectors ear marked for use when bad secotrs occur. (BTW I understand your point)

Yeah ideally 0, as even 1 bad sector in the wrong place can render the drive unreadable.

I recommend getting a copy of Hiren's or the Ultimate Boot CD and running a utility called HDAT2. Choose the mode that scans AND repairs sectors and let it run till it's done. It may take a a few hours or more, so just do it overnight or something.

It's revived two coworkers' laptops so far.

I had a copy of the UBCD, but I couldn't find a single scanner that would scan SATA, I settled on HDD Regenerator which seems to be doing the job, I couldn't boot Windows before, however since detecting those 3000 odd bad sectors Windows is once again working.

Would your advise be backup and replace the disk? Sadly its less than a year old, I'm normally a Maxtor man however this WD was cheap and had a 16MB Cache, do WD have a good name in the HDD market?
