Scan Exteernal DVD Rescue Disk

Hello,

I’m booting from Kaspersky Rescue Disk.

I’m trying to scan a dvd\cd which is connected to a usb port but the disc is not recognized as a parameter under “change parameter”.

I can see the disc and the data in the disc and i can mount disc to somewhere else like (mnt/KRD2018/Volumes) and use the disc but i can’t scan the disc.

Is it possible to manually add folder to scan? something like scan /path/to/folder/to/scan?

is there some special way or place i need to mount my disc in order to scan it?

One note, if i connect a regular USB Drive it is recognized and i’m able to scan it.

Please help me.
