(As a matter of fact, I'm not quite sure yet if the failure is total, or only block 0, at the time I didn't have anything but SRM and the install floppy to go on). I'm imagining it should be easy to find the first partition, and possibly gauge it's size (??) and find the second, and so on.. to reconstruct the partiton offsets. The drive in question is a SCSI, which I believe I installed as 'dangerously' dedicated. What can I do to do this on-disk? Or am I forced to copy the drive elsewhere? I'm fairly limited in terms of storage, but well motivated to do it :) I'm picturing the worst will be if block 0 cannot even be written to, as then the kernel will never accept it? - Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
