I'm looking for a copy, too. I have four (electrically) working Widget
mechanisms that need low-level formatting to be put back into life.

The remanent magnetic field on the disk fades with time. Data field
information is rewritten with every "repair" run, but address field info
isn't. If Widget/Profile cannot read an address field it believes the
block to be bad and uses a spare block. More than 32 spare blocks used
-> bye.
Reformatting cures this problem. But only low-level formatting. LisaOS
disk 1 or MacWorks Harddisk Install does not rewrite the whole tracks.
