Image format

MDS

Application that created the image

Alcohol 120%

What were you doing when it failed?

• I was converting the image to another format...
• I was retrieving image information...
• I was retrieving filesystem information...
• I was listing the filesystem contents...
• I was extracting the filesystem contents...
• I was creating a metadata sidecar...
• I was checksumming the image...
• I was verifying the image...
• I was calculating the image entropy...

Destination image format

Filesystem

Description

If an mds file specifies an extension that isn't mdf, aaru will fail to handle the image and close with ENOENT, regardless of whether you give the image file the extension the MDS specifies, or whether you give it the extension MDF.

Exact command line used

aaru i info [name].mds

Expected behavior

For this specific command, I expected aaru to retrieve image information.

There are 3 ways I'd imagine approaching this.

1. Giving an error that the format specified in the MDS is wrong, and that the user should change it to mdf themselves.
2. Checking for *.mdf regardless of what the mds file specifies.
3. Using the extension specified in the mds file

Personally, I'd lean towards 3, as even if a120 doesn't dump to that format, it will still happily mount images based on the extension specified in the mds, and, presumably the extension is specified there for a reason anyways.
Regardless, I'd be ok with any of the options, though.

Actual behavior

Image format identified by Alcohol 120% Media Descriptor Structure 
(a78fbeba-0307-4915-bde3-b8a3b57f843f).

Affected image

Any MDS specifying something besides *.mdf is affected. So far I've seen *.bin, *.iso, and *.img. (For both single and double byte, obviously).
