Filesystem

FAT

Description

Two .ST images from the same Atari ST game have been downloaded from the Internet. I do not have any information on how the image was created.

One of the image (floppy A) is correctly handled by Aaru. Aaru detects the FAT filesystem and is able to perform file extract.

Aaru does not detect any filesystem from the second image (floppy B). The same image however can be mounted on Linux (losetup and then standard mount). Files can be accessed and copies from the mounted partition.

I cannot exclude that the "faulty" image can be ill-structured.

Exact command line used

aaru fs info

Expected behavior

Aaru identifies the filesystem and can extract the files.

Actual behavior

Aaru does not detect any filesystem

File is truncated. If you resize it to the correct size it shall work.
