Hi, I have an 8GB IDE HD with FreeBSD on the last (4th) partition. I tried to install Rhapsody (MacOS X) DR2 the other day and now I cant find FreeBSD (No bootmanager sees it)...If I boot FReeBSD from a seperate HD and try and mount the partions I get: incorrect super block I have tried the dd and vnconfig trick posted to the list a while ago. I get outputs like: <snip> fs at block # 526784 last mounted on /usr f->fs_ncyl=1840 (1 4096 4096 = 7536640) fs at block # 526800 last mounted on f->fs_ncyl=1840 (1 4096 4096 = 7536640) fs at block # 592336 last mounted on f->fs_ncyl=1840 (1 4096 4096 = 7536640) <snip> I then type: dd if=/dev/rwd2s4 of=usr.raw bs=512 skip=526783 count=7536640 vnconfig /dev/vn0c usr.raw skip is one less than the number given in the output to make sure the first block is included. When I try to fsck /dev/rvn0c I get: ** /dev/rvn0 BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE WITH THOSE IN FIRST ALTERNATE ioctl (GCINFO): Inappropriate ioctl for device fsck: /dev/rvn0: can't read disk label Trying to mount /dev/vn0 Produces a file /mnt (not a directory) Any suggestions?
