Yeah. Those sindows are discouraging.
When you plug the thumb drive into a USB jack do you enter a mount command or does the operating system try to automatically mount the drive?
The thumb drive should show up as /dev/sda. You should be able to mount it if you open a terminal window, su to root, create a mount point, and use the mount command. Note that you will only have to create a mount point once. Here is an example where you are logged on as a normal user.
Code:
su -
<Password>
ls /dev/sda*
mkdir /mnt/sda1
mount /dev/sda1 /mnt/sda1
If the mount command says that you need to specify the file type then chances are that the thumb drive is formatted in FAT32. It might be formatted with NTFS. The mount utility should be able to figure that out by itself but you could still try either of the following variations of the mount command. The first example is for FAT32. The second example is for NTFS.
Code:
mount -t vfat /dev/sda1 /mnt/sda1
mount -t ntfs /dev/sda1 /mnt/sda1
See if that helps.
