Is it safe to use disk with many bad blocks?

[Ben Russo <ben@muppethouse.com>]

I have an 80GB hard disk.
badblocks shows that it has about 78M blocks.
The first 50 million or so can be checked (write patterns)
for many days with no problems.
Beyond that I start to get errors.

Does anyone have any experience with creating a partition
in the "good" part of the disk and just ignoring the rest?
