This is *not* necessarily a big deal, despite what your other response
told you.  Errors on reads do not mean that your drive's bad-sector
table is full; only errors on write indicate that.  If you can try
manufacturer's drive diagnostics, do that.  If you can't, then it's
harder to fix things up, but not impossible; write back if you
really can't use a low-level diag.
