My advice to the OP is to view the drive in DMDE. Then use Tools -> Copy Sectors to make an image of the FAT16 partition (start sector = 63, number of sectors = 1661121).
Now open the FAT16 image file in 7Zip and extract the individual files.

In the R-Studio or UFS demos, he could also just specify the range as a new virtual drive within the app, then mount it to the OS for direct access, assuming that the file system is intact.
