hello list, |
2 |
|
3 |
i purchased recently an external usb disk (HP SimpleSave, 1.5 TB). |
4 |
|
5 |
i re-formatted it with an ext4 file system, but i can't get rid of the |
6 |
"virtual cd" created by the manufacturer with some backup software. |
7 |
|
8 |
when i connect the disc, the system sees two devices: a hard disc (for |
9 |
example /dev/sdb, that i can format with the usual tools) and a virtual |
10 |
cd-rom (sr1 or sg1), that i'd like to erase but i don't know how to |
11 |
manipulate. |
12 |
|
13 |
here is the relevant part of dmesg: |
