From DiskSafe docs:
"DiskSafe" is a tiny dos.library patch that, uhm, keeps disks safe - from
invalidation by an accidential reset.
If you hit the reset key combination on the keyboard, the amiga usually
stops all disk IO operation and does not update the disk, usually leaving it
completely damaged. When booting again, the filing system tries to repair
the damage - this is quick and O.K. for disks, but takes long for big HDs
(usually around 20min per GB) and is thus not acceptable.
"DiskSafe" installs a patch that completes all disk IO before the reset
actually is allowed to occure and thus leaves the disk validated, even when
you hit reset within a disk IO operation. But in order to make this working,
some special hardware must be present, which Commodore build not into ALL
amigas, read the Requirements
However, DiskSafe 1.18 offers an "replacement" for the reset key that works
for all Amigas. Check the Config section of this guide how to do that.
Starting with release 1.10 DiskSafe can be setup to protect the ColdReboot()
library function as well, hence protecting the system from accidential software resets. (Etc.)
