Make an image with

dd if=/dev/sdb1 of=image.fat32

except you should add 'conv=noerrors conv=sync' to keep going past bad
blocks and replace unreadable data with zeros. If the whole thing was one
partition, that's going to be difficult though - another reason to keep
partitions a reasonable size.


then bind it to a loop device:

losetup /dev/loop0 image.fat32

and run fsck and other software on /dev/loop0. That'll allow you to
experiment without altering any bits on the original filesystem.
