   — TECH QUIZ —

   Back in early 2020, I burned a live CloneZilla CD, which I used on a Pentium 4 system to back up a good number of IDE hard drives.

   My problem, in 2024, is that I can’t remember how to mount the damn images >>> on my Macintosh <<<.

   Important Note: THIS IS A FAT-16 FILESYSTEM.

   Suggestions ????

     @artandtechnic determine file types by filenames was a bad idea in 1981 and Mac figured out how to avoid it in 1984! And yet...

     Additional fun:

     Since CloneZilla creates filenames like “sdc1.dd-img.aa”, the Macintosh’s `hdiutil` refuses to accept them as valid disk images … because it’s a “.aa” file, and not a “.img” file.

     Seriously.

     You have to copy the file to another volume (since the source is read-only), rename it there, and then you can mount it.

     Sigh….

     With another disk image, I noted that I could simply use `hdiutil attach -nomount` with the .img file that CloneZilla produced for a FAT32 filesystem… as it showed up immediately in my device list after running that command.

     Ok, so I think I *may* have solved at least this issue.

     What worked for me:

     1) Using `cat` to merge the MBR, the data-after-the-MBR, and the actual sda1.dd.img file into a single .IMG file on another drive. Running `hdiutil pmap` on that image showed that it was recognized as a “PC Partition Scheme.”

     2) Then running `hdiutil attach -nomount` which attached the “FDisk_partition_scheme” and “DOS_FAT_16” partitions.

     3) Running `mount -o ro -t msdos` to manually create a mount point. This gave…

     … an error [“mount_msdos: Unsupported sector size (20487)”] which suggests I probably did something wrong, and need to look into it more later… but actually resulted in the partition successfully being mounted.
