Success!.......Well, sort of.
Following a thread I read on this forum I managed to find a way of getting my external hard disk to appear in the devices section of Konqueror. That isn't the problem though. Now I've done that I can remember the changes I made to the line so I could access it as a non root user. I looked through the manual again and now I'm having to go through all the combinations until I get the right one. This time though, instead of constantly typing it in the Konsole, I'm going to add a line to the fstab.
In the Konsole I typed:
As I understand it, 'rw' gives read/write capabilities, /dev/sda1 is the name Linux gives it because of SCSI emulation (despite there being an IDE drive inside the enclosure). /mnt/usb is the substitute for /dev/sda1. 'users' or 'user' allows a non root user to mount the device. If I were to put owner in the the only person who could unmount the device is the one who mounted it in the first place. As for umask, I'm not sure whether it should be 0000,000 or 0033. You'll have to explain that one to me.
mount -t auto -o rw,users,umask=0033 /dev/sda1 /mnt/usb
It would be great if you could tell me what is wrong with that line and what to do so I can allow it to be accessed by a non-root user.
