Shouldn't modern drives do it automatically? From what I read, every
modern drive comes with some spare sectors to allow migrating data from
damaged sectors. There's also a S.M.A.R.T statistics value (check with
your 'smartctl' utility) indicating how many sectors were moved.
Thanks for the reminder about SMART (also goes to Peter).
I'll check and see what SMART says.
Already have a 200Gb disk waiting at home (didn't have any smaller
parallel IDE disk at the store).
I don't know for sure, but my intuition tells me that reading does not
migrate data of bad sectors.
They are marked as "scheduled for migration" by harddisk however (if any
spares remain).
Actual migration will take place on writing into the sector.
IMHO low-level format operation should not be done when bad sectors are
encountered, as it assumes that media is free of errors.
I would not be surprised if factory-based low-level format entails
writing and then verifying some data.
After this is done, any subsequent low-level format would do more harm
than good, as bad sectors (even if proved good immediately after
low-level format) will pose danger to data stored in them.
I would be glad if somebody provide us with exact information.
