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. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/ _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
