how do you repair a disk that is reported to have many bad sectors and fsck reports that the filesystem is mounted.

You could use the badblocks command to create a list of bad blocks.
Then you can format the disk with mkfs or mke2fs (with the -l option you can provide a bad blocks list that won't be used in the filesystem).
This is just a temporary solution though. When there are bad sectors, more will follow.

Not necessarily. I have some bad sectors on my hard drive. What I did was to make a partition on the part which has the bad sectors. Then I just do not use that particular partition. It's been two years now. The rest of the hard drive is still working well, 12-16 hours every day, seven days a week.

i ran badblocks command with the "-o file" command and the hard disk came out clean. i ran it as /dev/sda i.e the whole disk not minding partitions. wondering why blag says the disk is sick?

Well, half of it was guesswork and half of it was from my experience with literally thousands of hard drives.

I first noticed that my hard drive was failing when my Windows installation became unstable. Sometimes it boots up. At other times, it just died. Finally it died totally. I couldn't even re-install it.

That was when I tried marking off the first part of the hard drive. I started by marking off only 10Mb. Didn't work. So now I have marked off 100Mb. Just left that partition totally unallocated. I did that a couple of years back. My hard drive is still working up to today.

It's good that my Windows died. Otherwise I wouldn't have found Linux. Now Linux is my main os. I have Windows 8 only to play World of Warcraft.
