Well, firstly, make a backup. Then, in single-user mode (for paranoia's sake) say : # bad144 -s -v /dev/rwd0s1c (or whichever slice you're unsing). (If you read the manual page, you will know that this scans the entire disk for bad sectors) If you can't follow the badsect manual page then I feel really sorry for you, it's the nicest piece of handholding I've ever seen in a sysadmin manual page. I can't vouch for the command _working_ of course 8) > -Vince- vince@kbrown.oldcampus.yale.edu - GUS Mailing Lists Admin -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] My car has "demand start" - Terry Lambert [[
