One approach would be to use a binary search, or rather a variation of
the binary search, to find the bad sections of the disk.  It's a
somewhat tedious process, but if your alternative is to replace the disk
for a high price, it might not be so bad.

Write a label to the disk, partitioning into five or six equal sized
swap partitions.  Hammer away at each with /dev/zero; hopefully only a
few will have errors.  Note the sectors boundaries of the partitions
which have errors.  Relabel the disk, further subdividing those
partitions which contain bad sectors.  Hammer with /dev/zero at those
smaller partitions... repeat this process until you've identified enough
usable space for swap.  I'd imagine the first iteration is all you'd
really need.
