I think that it has been more than 10 years since hard drives started
automatically mapping bad blocks to spare blocks; when they start
showing bad blocks they've run out of spares. Its probably time to find
a new hard drive.
That said, yes you can keep the filesystem from writing on bad blocks by
running a fsck on the filesysem while its unmounted, and select the
appropriate badblocks option. Use the -f option to force a check even
though the filesystem is marked as clean.
For e2fsck its -c -c (to use a non-distructive read-write test)
Not all filesystems support badblocks (e.g. JFS) but rely on the hard
drive to handle them transparently (see above).
The hard drive and the computer are only related by a cable and some
screws. If the computer does everything you need and is reliable, it
may only need a new hard drive.
