I recently replaced the suddenly-ominous-sounding 2GB SCSI HD in my A1200 '060 tower with a CF card on a SCSI-to-ATA adapter. This device:
http://www.flickr.com/photos/blakespot/4392374643/in/set-72157604300573758/I hooked it up to the SCSI chain, copied the old disks contents over to the ~2GB partition on the 4GB card, and booted up. I got a disk not validated error. I let AmigaOS do its thing, clicked Retry, and it rebooted -- I got the Indivision FFixer screen as I do at every boot -- and then it came right back and gave me the same message. Ad infinitum.
When it gives me the error, I can see the activity light on the card board lit up so it seems to be doing the revalidate thing. It eventually stops, and that's when I do a Retry click.
Any ideas? Thanks.
