FixDisk is a program to recover as much as possible from a defective
disk.  I don't claim it is better than 'Diskdoctor' or 'DiskSalv', but
it has some features the others don't have: first of all it can
recover damaged (unreadable) tracks, it has functions to check file
integrity, to check the directory structure and functions to undelete,
copy or show (even defective) files, fix corrupted directory pointers
etc. Everything can be selected with an intuition interface, so
everyone can determine what action should be take place by himself.

Now the bad news: The program does not keep track of 'loose blocks'
i.e.  files without a file header like DiskSalv. It does only work
with disks / partitions using a maximum of 4063 blocks. It may work
with larger disks too, but I don't have a hard disk, so I couldn't
test it out. Disks with more than 4063 blocks are rejected by the
program. You may force the program to accept <48 MB partitions adding
'DOOM' to the command line (i.e.  'FixDisk doom').  As I said before,
it has not been tested and should only be used if anything else
failed, and you're just about to format the partition.
