Upon restart, there was a message that ad0 had an unrecoverable error (media changed). It's a hard disk. I didn't notice any gnomes breaking into my computer and changing it on me. No matter. It won't boot. I installed FreeBSD on an empty partition of another disk, which is how I got to where I am now. Naturally, I have no backups.
My plan is to reconstruct the partition table and then all should be fine. I've determined that my files seem to be in tact using 'strings /dev/ad0 | less'. It even looks like part of the partition table remains.
% fdisk ad0 ******* Working on device /dev/ad0 ******* parameters extracted from in-core disklabel are: cylinders=59598 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=59598 heads=16 sectors/track=63 (1008 blks/cyl)
fdisk: invalid fdisk partition table found Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: <UNUSED> The data for partition 2 is: <UNUSED> The data for partition 3 is: <UNUSED> The data for partition 4 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 63, size 60074721 (29333 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 1; end: cyl 205/ head 15/ sector 63
First, are there any tools that can look at the disk and guess what the partition table should look like? Failing that, I figure I can take a look at the disk where I think the partition edges were and look for some sort of cues to tell me what the partition boundaries ought to be. Can you all help me with this / guide me through it?
