Heh, for starters I assumed (always a bad thing) that fsck wasn't available because I did a 'which fsck' and got 'which not found' as a response.

Can you explain or point me to more info on why that was a poor choice on my part? To explain more this is a 250 GB hard drive which is the primary slave and is mostly used as a data repository and shared via samba on my home office lan. > But I think fsck should be able to work through it. snip > It the manual fscks don't work, then you may have to try some > extreme tactics to recover things on that partition or abandon snip > If you end up rebuilding the drive, then the next time make a > FreeBSD slice and then make a partition within that slice to > avoid that 'dangerously dedicated' config. I am not getting past this error with fsck. Get 16 lines saying: ad1: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=xxx for xxx in [191..206] then a msg listing disk sectors that can't be read 128 through 143 and finally: /dev/ad1s1c: NOT LABELED AS A BSD FILE SYSTEM (unused) If I can recover the disk which has about 60GB's used out of 250GB and lose a few sectors it's really not a bad deal probably, but how do I go about trying at this point? Also it won't reboot now, although I've run fsck complete including on ads0. Do I have to edit /etc/fstab so ads1 isn't mounted to get a good boot? Unfortunately /usr isn't getting mounted and I have not editor available afaik. Marty
