1) what file system (sounds like ext2, reiser, or fat). 2) what is the media and interface (compact flash, PATA, SATA, SCSI.) The answers will dictate the next steps. You could boot with a live distro, my favourite is systemrescuecd, though Ubuntu or even Knoppix should be fine as well. Once booted you could check the drive with: parted /dev/<dev> print to see what partitions are there. This would also tell you the file systems on that disk. fsck by itself will do its best to autodetect the FS, but I tend to specify it explicitly on the command line (eg. fsck.ext3 -cfv /dev/sda1) Hth, -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkl2T5QACgkQwRXgH3rKGfPmqwCdF0F5tbQuKfwGZq77kEACMTGO tsAAoJ5ChSgfV9G3aJTyzsGrWBI+FPJW =hucV -----END PGP SIGNATURE----- _______________________________________________ clug-talk mailing list [email protected] http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying
