What can I do for such a case? Can't Linux mark bad blocks so that they can't be used? Does it have something like scandisk or chkdsk?
There is 'badblocks' which can destructively or non-destructively look for bad blocks. If your harddisk is seriously damaged though it will find a LOT of these and it may take literally days until it gets to the end of the check (I tried that once - found that the first N and last M blocks had a high error probability but block 0 was still good; then set up the disk so that these blocks were not in any used partition. Last week the disk died soundlessly. Only do this stunt if you have very good backup and lots of time to spend) Modern disks should register & remap (a few) bad blocks by themselves I think. You can feed the output of badblocks back into mke2fs so that these blocks are avoided during fs construction.
Don't tell me that the harddisk cannot be used anymore cause I have another harddisk which is less than 2 years old since I bought and it has some such problems. Luckily, it can still be used. In a day, I use less than 8 hours and I don't use the computer everyday. (Average of 3 hrs a day)
If it's under guarantee you can probably exchange it under the manufacturer's exchange program. If it's a Fujitsu, check that it isn't one of the 'bad series' that has known defects. Disks can run 24/7 without trouble. Power cycles are more damaging to them than continuous running IMHO.
