Hi

Thanks to those of you who made suggestions when I could not get 10.2 to
recognise a CoolGear USB removable HDD.

It turned out the problem was with the USB hub inside the external case
drawing too much current and lowering the voltage to marginal levels.
It was drawing its current from the server USB socket despite the fact
that the external case had its own power supplied from the wall AC
socket.
My hardware man cured the problem by connecting the +5v regulated supply
from the power circuitry to the hub (via the key switch). Turns out the
box was an earlier model - the manufacturer now supplies boxes with the
same mod.

This prompts 2 questions though. Any advice would be gratefully
accepted.

1. Is it OK to just unplug the device without using umount?

My practice hitherto has been to:
1. plug the cable into both the server and the case.
2. put the disktray in the case.
3. Switch on the power to the case
4. switch on the tray keyswitch, and wait for the lights to settle
5. Access the device via /media/disk (or whatever shows up in mount
for /dev/sdb1

This is not as complex as it sounds, and probably not too important.
Now comes the part that bothers me:

To remove the disc, I have been doing the following:

1. umount /dev/sdb1 (or whatever)
2. switch off the disktray
3. remove the disktray 

In fact there is a keylock. You cannot remove the disktray unless you
unlock with the key.
The question: Is step 1 necessary or unnecessarily cautious.

Question 2

How can you reconfigure SuSE 9 to imitate the behaviour of 10.2 with
regards to mount points (i.e. /media/disk instead
of /media/verylonghardwarebasednamewith\spaces?

regards
John O'Gorman
