If the bad blocks are not under any vital file system meta-data (boot
blocks, inodes, et al), you can use the badsect(8) command to create a
file that includes the bad block.  However, you really want to buy a new
hard disk if this one is remotely recent, as it's likely a sign of
impending drive failure.=20
