View Full Version : [ubuntu] USB Drive usage at the command line
December 9th, 2008, 10:30 PM
How do I view and copy files from a USB drive and my home folder?
I have three books on linux and not one explains this simple operation. I already have plenty of information on mount points, device files, mounted devices, mounting, unmounting and changing permissions. Everything but what I'm looking for.

Did you know the basic commands?
ls : display the content of a directory
cd : change directory
cd .. : move up one directory
cd / : goes at root directory
cp source destination : copies files from source to destination
mkdir : make directory
type help and you will see a list of commands
type help command to have infos about the command
To access your drive, cd to your mount point (usually /media/disk-1 or /mnt/disk-1)
ls /media : you will see mounted media
ls /mnt : they also may be there
cd /media/name of dir
ls : You should see the content.
Are you sure you mounted correctly the drives?

Two problems surfaced.
Multiple partitions of a software RAID array gives a lengthy list of /dev/sda*, sdb* devices. Which were the two SATA hard drives. Inserting the thumb drive resulted in sdc and sdc1 in the list. I didn't catch the import of this being two partitions at first.
Secondly: After editing /etc/fstab and creating appropriate mount points in /mnt, I issued the mount -a and received file system errors. Then it dawned on me that I was using a U3 Thumbdrive (which has autoexecuting software in the first partition). This apparently is not recognized by the kernal nor the mount -a. (Though this does work on an Ubuntu Desktop system, 8.04)
Doing a manual mount of the second partition (sdc1)to the mount point (/mnt/usb1) and then "ls -l /mnt/usb1" yielded the list of files on the device.
Since these devices are commonplace I'm sure I am not alone.
Lesson learned: You can use the storage on these devices by just ignoring the 1st partition.
