I have a Zalman VE-350 with a dozen of ISO on it. It's supposed to be recognized both as a hard drive and a disk drive by the OS, with whichever ISO is selected in the disk drive. However, a few of the ISO don't seem to work.
In hdd mode, I can do
mount win7.iso /tmp/win7
and it works fine.
However in disk mode, if I do
mount /dev/sr0 /tmp/win7
I get
mount: /mnt/nas: wrong fs type, bad option, bad superblock on /dev/sr0, missing codepage or helper program, or other error.
Most of the ISO work fine, except one of Windows7 and one of Fedora Live. It's always the same ISO which do not work. I tried to mount the ISO on multiple computers, none worked. I have updated the firmware to the latest version available on zalman.com (2.0.2)
Has anyone encountered such an issue before ? How did you solve it ?
If not, how would you go about diagnosing this further ?
