Might be helpfull if I explain what the entry in fstab is doing,
/dev/sda1 /media/TREKSTOR vfat rw,users,noauto 0 0
/dev/sda1/ = device name
/media/TREKSTOR = mount point. This has to be an existing directory on you root fle system. for instance, for my ntfs hard drive I have /media/ntft and for my reiserfs harddrive I have /media/reiserfs
vfat = file system i.e. ntfs, fat32, ext3, reiserfs,
rw = read/write can be "ro" for read only
users = "rw" applies to all users logging into your system. "nouser" would mean only root has access.
noauto = will not mount on boot. "auto" mounts on boot.
0 0 = somthing to do with the order of backing up. go ask a guru!
I think you will be okay with editing your /etc/fstab with
/dev/sda1 /media/usb auto rw,users,auto 0 0
if you do start(kde start) --> run command --> "kdesu kate" you can edit /etc/fstab as root.
then, in the terminal input,
sudo mkdir /media/usb/
- we have to make this mount point exist.
sudo mount /media/usb/
and you should be able to access any USB drive that you put into you computer. . .hopefully :-)
