I want to backup usb flash disk. I only can see it in acronis true image server for linux (9.1.3718 trial), and only if computer was booted with usb flash in it. I see it under "dynamic and GPT volumes". If I unmount flash disk (acronis is off) and try to load trueimage, it give me error message: "Failed to read from sector 128 of the hard disk 0", if I press cancel it loads and shows me the disk, I'd unmounted (under dm-5). In windows version I don't see usb flash disk at all.
