Does anybody know how to repair a broken disklabel?
I've got a 730mb Quantum drive here with a messed up label. I just put in
a 4091, and hadn't quite gotten the termination down right (I don't have any
internal drives hooked up, so it got upset).
When the termination wasn't right, I ran hdtoolbox. It saw the disk, with
the correct drive type, but it said it was "Changed".
Fine. I clicked "save changes to disk" not realizing what a mistake that
would be. When I rebooted, HDToolBox said the drive type was "Unknown".
AmigaDOS saw the AmigaDOS partitions that I had on it (2 amigados partitions).
I can't get bffs (1.3 I believe) to mount the root partition so I can
read a kernel off of it. No matter, I have a generic kernel sitting in
AmigaDOS land (man, was I smart when I put that there!).
I boot NetBSD with the generic kernel. I get to single-user mode just fine.
The disklabel command shows me my partition table, with everything just fine.
I just can't edit the disk with HDToolBox, nor can I get bffs working.
I'd like to reset the drive type, without blowing away my partitions (which
NetBSD has _no_ problems with). Any ideas?
I can dd the beginning of the disk off, if anybody knows which byte I need
to change. Actually, I could probably get NetBSD running and write a program
to seek to the correct location and change it.
I just need to know what to change. Ideas?
Thanks guys!
