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.
Curious. I hinted at power, but I was still far from the mark...
This prompts 2 questions though. Any advice would be gratefully accepted.
1. Is it OK to just unplug the device without using umount?
Better not. The general answer is "no".
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.
Check with the command "mount". If you see a "sync" option applied to the device (all used partitions) then it is safe - usually. If you don't see it, then it is certainly unsafe. I always use "umount whatever" to be on the safe side. It's better to waste some seconds than spend a day repairing a badly damaged disk.
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?
There was a trick to mount on a fixed mount point name. It was published on the SDB, and I did some investigating at the time that I wrote to the list - I used 9.1 or 9.3 - but I can't find that email right now on a quick search. - -- Cheers, Carlos E.
