[Bug-ddrescue] Kernel panic :-(

[David Morrison]

Oh dear.....

I started copying a disk to another disk. After a minute or so, I 
realised I had forgotten an argument so hit CTRL/C to stop ddrescue. 
A kernel panic occurred.

I shut down the machine and restarted it. Halfway through the boot 
process, another kernel panic.

I removed the disk I was writing to and restarted it. It booted fine, 
no problems.

I connected the disk via a USB case and immediate kernel panic.

I restarted, started a utility that forces disks to mount read-only, 
then connected the disk again. Kernel panic again.

I am guessing that the disk has been left in some inconsistent state 
which is upsetting the operating system when it tries to look at it.

Any suggestions to recover the disk? This is Mac OS 10.6 on a Mac 
Pro. Would other operating systems be able to cope with this, maybe 
reformat it?

And apparently caution is required about interrupting ddrescue when 
it is operating!

Thanks

David
