Read the 'badsect' manpage for intimate details on the process. The "bad sector number" you want is the 'fsbn' (filesystem block number) value, ie 1006499. If we assume that /dev/wd0s2e is mounted as /foo, you would say : # cd /foo # mkdir BAD # badsect BAD 1006499 # cd / # umount /foo # fsck /dev/rwd0s2e (respond as detailed in the badsect manpage) > Richard -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
