badsect

[falaki at ce.sharif.edu]

Hello;

I have a hard disk that seems to have some limitted number of bad sectors.
I want to use badsect to avoid these errors.

   ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=27546816
   ad0: FAILURE - READ_DMA timed out

I tried this:

   #badsect /mnt/data 27546816

and got:

   block 27546816 out of range of file system
   don't forget to run fsck ...

What should I do?

Thanks in advance,
MHF.
