I've only done this on SCSI (via an Adaptec 2940) - where it worked, I guess
for IDE it might be different (maybe someone else will know?)

Yes, easily... I've used partitions up to around 40Gb, but I wouldn't recomend
making them too large with no good reason, as they take ages to fsck (i.e.
check) if the system goes down/panics while busy... (And they can take quite a
bit of memory/swap space to run fsck on as well!)

You could concatenate your _drives_ together if you want?!, then have an 18Gb
partition that spanned both... (Not good from a fault tolerance point of view
though). If your using 3.1 look at either CCD or Vinum for concatenating them
(or even mirroring them for fault tolerance)...

[CCD is more tested, but Vinum is 'better' - but not completed/tested as much
yet... If it were me I'd see if I could get on with Vinum first, then go to
CCD if you can't :-) (man vinum, man ccd].

Karl
