I've got this Amiga 4000 with a Phase 5 PPC board (233 mhz 604/50 MHz 68060) with 128 megs of ram on board running OS 3.9. Its never been too terrifically stable to be honest, and the other day it crashed while I was browsing the web - the system came back up and it wanted to validate the disk.
I get the error > "DH1 Program Failed (error #80000003). wait for disk activity to finish. suspend/reboot"
This is on a 6.5 gig Seagate UW scsi disk connected to the phase 5 controller.
I booted off an OS 3.1 disk, same error.
Is there any way to resolve this or will have to format the disk and start over? I'm not entirely sure how that will work because even when I run the installer to do this you can hear the drive trying to validate and eventually when I get this error the rest of the machine becomes un-usable - even if I hit suspend.
I suppose if its a phase 5 problem I could drop the old cpu board in there and find if that helps (actually now that I think about this I can't - since the disk is scsi). I rather not reinstall. The toaster software doesn't like installing onto a disk greater than 2 gigs

and it took a while to get setup.
