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?
