XRASE.COM (v3.3) - Version 3.3 update: checks for gaps in
remaining directory entries (a file with extents 1, 2 and 4
will not be unerased); fixed a couple of bugs reading last
directory sector, block vector; a few code improvements.
XRASE is an unerase program that, unlike many such programs, (1)
works on all types of disks (2) will not unerase two versions of
the same file, and (3) checks for reused allocation blocks and
will not unerase a file part of which has been reallocated. It
accepts only unambiguous filenames. Unerased files are restored
to the current user area. The output of the program tells you
whether the file has been unerased and if so which "extents."
This term is used a bit loosely to designate directory entries
rather than extents in the narrow sense (=128 sectors). This may
be confusing to "end-users," since many systems will have more
than one extent per entry: e.g. the Kaypro-10 has two per entry
on both hard and double-sided floppy disks. (CP/M hackers can
find this information from the "extent mask" in the disk
parameter block.) So tell your friends not to worry if they find
they have unerased "only" extents 1 and 3 of a file. Versions
3.2+ are reentrant; as with ABUSER, to exit, type a CR at the >>
prompt.
