There is all HD of my system but no trace of USB pen |
did you remove the USB device before running that command?
follow these basic steps in order 1. as root run the following command BEFORE YOU PLUG IN THE USB DEVICE Code:
# tail -f /var/log/messages 3. once you see the /dev/sdX or just the sdX press and hold ctrl+c on the keyboard to break the tail command. 4. type the following command Code:
# fdisk -l /dev/sdX 5. if the device is formatted then make note and mount it appropriately, if not then partition and format it as you desire. etx2 or fat-32 as required for your needs. |
It is perfectly OK to have sdb only instead of sdbx, it is possible the device has no partition table. It still can have a filesystem on it.
