I have a (very old) CD which is supposed to be mountable both on the Mac and Windows. Using Virtual Box, I can see the Windows partition, but on macOS I can’t.
Disk Utility sort of sees it, but the volume is greyed out and cannot be mounted.
diskutil list I get the following:
/dev/disk7 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: CD_partition_scheme *1.5 MB disk7 1: Apple_partition_scheme 1.3 MB disk7s1 2: Apple_partition_map 1.0 KB disk7s1s1 3: Apple_HFS Aussie Maths Invaders 531.5 KB disk7s1s2
which suggests (a) that it can see it and (b) the format is HFS.
I have two copies of the CD, and neither of them can be mounted, which suggests that it’s probably not the media itself.
I cannot successfully mount the Apple Partition using either
diskutil, or at least with the options I have tried.
I have tried the following:
$ diskutil mountDisk /dev/disk7 One or more volume(s) failed to mount $ mount -t cd9660 /dev/disk7 ~/cd mount_cd9660: Invalid argument mount: /Users/mark/cd failed with 1 $ mount_cd9660 /dev/disk7 ~/cd mount_cd9660: Invalid argument
I am on an iMac running macOS Catalina 10.15.6 an external DVD/CD drive.
