Microsoft Windows 2000 has a utility "chksdk" for repairing disk
problems. It has an option "/R" that locates bad sectors and recovers
information.

My disk drives are newish ATA 100 units from Maxtor and Western
Digital. For such recent technology, does the "/R" option have any
use? Or does the disk drive take care of bad sectors all by itself?

For the most part, a modern drive has spare sectors it uses in place of
known bad ones. /R isn't too useful today, although it could be useful on
a floppy. It might also work on a hard drive where some other sort of
glitch (bad cable, controller, power glitch) caused Windows to mark
sectors as bad.

chkdsk operates at the file structures level. The drive
bad sector management operates at the sector level,
below the file structures level. And not all bads seen
by the drive are automatically transparently managed.

And caused Windows to mark those sectors as bad.
