How does one recover from a corrupted disk on a standalone machine?
Assuming just a few blocks are corrupted, and one of them happens to
be the label block, what can be done from the FEP to repair them? Or
do I have to reformat the whole thing?
In Genera 7.2, the only useful FEP command is Disk Format, and it looks
like a big hammer. Might there be something more graceful?
The FEP label is replicated a number (like ~ 32) of times, so you must
have more than a few blocks corrupted if you cannot boot Lisp.
Assuming that only some of the label copies are damaged, you can
rewrite them from Lisp. Look at SI:EDIT-FEP-LABEL in
Only if you bought optional sources. SYS:L-SYS;FEP-SALVAGE is an optional
source, not a basic source.
