I have installed these ports


If my understanding of reading their documentation is correct, they all 
need a empty disk to copy the bad disk sectors to in sequence.
Is this a correct understanding?

msdos fat32 file system has a backup fat table as stated in the docs. Do 
any of the sectors rescue programs read the backup fat table?

Not interested in the XP system or programs directors. Just want user 
data files created by adobe pagemaker. Dont know what the file extension 
is for sure or if there are any way to ID the file from internal 
content. Best guess I have on file extension is .cv5  Do not have a file 
to examen.

What are the general steps I need to do to recover data from this msdos 
FAT32 disk with corrupted fat table and maybe corrupted data?
