    Hello everyone, and thanks in advance for any info you can provide!!!
    
    I have a dd'ed image that fsstat reports as;
    --------
    [root@localhost morgue]# sfdisk -l disk2.2.2.dd
    Disk disk2.2.2.dd: cannot get size
    Disk disk2.2.2.dd: cannot get geometry
    
    Disk disk2.2.2.dd: 0 cylinders, 0 heads, 0 sectors/track
    Units = megabytes of 1048576 bytes, blocks of 1024 bytes, counting from 0
    
       Device Boot Start   End     MB    #blocks   Id  System
    disk2.2.2.dd1   ? 937476+ 1203314- 265839- 272218546+  20  Unknown
    disk2.2.2.dd2   ? 649504+ 912676- 263173- 269488144   6b  Unknown
    disk2.2.2.dd3   ? 263178+ 945972- 682795- 699181456   53  OnTrack DM6 Aux3
    disk2.2.2.dd4   * 680970+ 680980-    11-     10668+  49  Unknown
    ------
    
    Below is some od output of the beginning of the image.
    ------
    0000000 353   > 220   M   S   W   I   N   4   .   0  \0 002   @ 001  \0
    0000020 002  \0 002  \0  \0 370  \0 001   ?  \0 200  \0  \0   ?  \0  \0
    0000040  \0 374   ?  \0 200  \0   ) 341 024   ]   0   N   O       N   A
    0000060   M   E                   F   A   T   1   6             361   }
    0000100 372   3 311 216 321 274 374   { 026  \a 275   x  \0 305   v  \0
    ------
    
    I can mount if "successfully" with;
    ------
    # mount disk2.2.2.dd /mnt/vfat -t vfat -r -o ro,loop,show_sys_files=true
    
    # mount 
    /root/practical/morgue/disk2.2.2.dd on /mnt/vfat type vfat 
    (ro,loop=/dev/loop0,show_sys_files=true)
    ------
    
    The top level directorys appear "good", but as soon as you drop into a 
    folder or two down, I start getting "garbage" from ls, cat, less, cp... 
    The file and folder names look like pieces from the files themselves 
    rather than the FAT. While the content of the top level files can be 
    accessed (less, cat...), the lower level files contain "garbage".
    
    I have tried mounting as fat=12, fat=16, fat=32 (which failed), and 
    several other options in mount but keep getting slight variations on the 
    same "corruption" problem.
    
    So my question is, does anyone have any suggestions on what the problem 
    might be, and how I should proceed?
    
    Again, thanks Much!
