I have Windose completely erased ... booted with a system-disc but it does not 
recognise any drives besides a: and b:, guess this does not count as a test ... 
I am completely ignorant when it comes to hardware and so I won't touch the box 
today, but just a minute ago someone came in, told me that there is a spare 
scsi-board somewhere and probably also a spare cdrom and that I should ask my 
sensei about those when he is back, so I have to postpone this probably until 
Thursday. 

What a pity, they were having doubts about Linux and hardware and I said "no 
problem!" ... :-(

Thanks for the information! Ah, I remember now the master and slave thing when 
installing this other harddrive... (I mean when I was watching ...)

Now this sounds interesting ... I was wondering how I could treat some of my 
hardiscs as a single one, just took the mountpoints for each drive as suggested 
by the installation disks, but I guess I have a weird partition setup now ... 
The suggestions for partition sizes in the handbook that came with the Debian 
CDs gave some examples but said these setups were not optimal, why didn't they 
give a better example then? Maybe "as many suggestions as sysadmins" or 
something along these lines ... I will check the tlug archives, I remember 
partition sizes have been discussed here before. But how do I make one out of 
two?
