Oh yes, had fun with fstab in single user mode yesterday ... I'd put a 
spelling mistake in /etc/fstab that was fun as it was my first venture 
into single user mode. Took me 20 mins to realise that only / was 
mounted and that /use wasn't hence no editors or shells.

As this is a production server (its only my home file server) and the 
card was an ebay special at sub $200 I'm happy with the performance.

I may play around with moving them when some more routine maintenance 
comes up but as I am only writing to it over the 100Mbit network 
50MB/sec is more than enough for what I am looking at.

Many thanks for the help.

Cheers
Richard
