Hi! I have a hard disc that I think must have been set up wrong initially... It was however working fine, but at some point filled up to capacity, wherapon the next reboot it failed to mount. System is 4.8-RELEASE, Generic Kernel. Currently the disc shows: luggage# mount -r /dev/ad5s1e /mnt mount: /dev/ad5s1e on /mnt: incorrect super block luggage# disklabel -r ad5 # /dev/ad5c: type: ESDI disk: ad5s1 label: flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 14593 sectors/unit: 234441585 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 234436482 0 unused 0 0 # (Cyl. 0 - 14592*) e: 234436482 0 4.2BSD 16384 16384 300 # (Cyl. 0 - 14592*) Warning, partition c doesn't cover the whole unit! Warning, An incorrect partition c may cause problems for standard system utilities luggage# fsck /dev/ad5s1e Can't open /dev/ad5s1e: Invalid argument luggage# fsck -b 32 /dev/ad5s1e Alternate super block location: 32 Can't open /dev/ad5s1e: Invalid argument luggage# file -s /dev/ad5s1e /dev/ad5s1e: can't read `/dev/ad5s1e' (Invalid argument). At this point I am stuck ... most of the "Invalid Super Block" messages I can find when searching relate to cd-roms. If I could mount the disc even read-only, I could copy the data off. Can anybody give me any clues on where to go from here? Thanks in advance, Rob
