Now what? punt? You're using the default "whole slice" partition, ad1s1c. My guess is, you're using the default disklabel for that slice. If you look at that disklabel, # disklabel ad1s1 you'll see a line like this: c: 156301425 0 unused 0 0 # "raw" part, don't edit Now, fsck uses external helper utilities to check the consistency of various types of filesystem. If the filesystem has an entry in /etc/fstab, it'll pull the type from there if you specify the mount point. If you specify the device, it looks like fsck is using the disklabel rather than actually "tasting" the partition to determine what fsck to use. You can fix this by disklabelling your device and fixing the type of partition "c": this should be ok. You can probably also tell fsck explicitly what type of filesystem to check, or just invoke the appropriate fsck_ufs directly. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44 (0)117 3317661 http://ioctl.org/jan/ Usenet: The separation of content AND presentation - simultaneously.
