I installed 5.0R on a set of SCSI disks that ran in my box side by side with the 4.7 installed on the IDE drives. I switched in the BIOS to boot the SCSI disks and installed 5.0R there. Then I fsck'ed /dev/ad0s1a,e,f,g and mounted them. Already noticed that - although I shut down the machine smoothly - 5.0 didn't find ad0s1g clean and did a salvage on summary or something. For some reason I booted back into 4.7 on the IDE drives and 4.7 suddenly found all filesystems bad and forced into a filesystem check where on every FS it had to search for an alternate superblock since it detected a mismatch in the summary information on the standard and first alternate superblock. Strange. And I had no backup which I'm doing now quickly :-) -- Chris Christoph P. U.
