Really I know nothing of RAID. My only experience is a software-based, 
2-drive RAID system I have on a Win NT server here. One drive goes down 
and the other drive is still there as it's a copy. I don't even know (or 
really care to know) what sort of RAID that is.

If the drive is now accessable in the RAID environment, then I would 
suppose that fdisk should tell you that you have a larger drive? Does 
all of this RAID stuff show up as a single logical drive? Anyway, if you 
added 250GB, for instance, then somewhere fdisk should show you that 
this space is there. However it may not pe partitioned yet unless the 
Dell software did that for you automatically.

Anyother possibility, I suppose, is that the drive is partitioned, and 
possibly even formatted, with a file system type that your kernel 
doesn't recognize. for instance, if the Dell software put NTFS on it 
then you might not be able to access it even if you can see the partition.

Anyway, not being where the machine is it's pretty hard to imagine all 
the problems you might be having. Drop another note back with more info 
and I'm sure someone can help. Heck, if the machine was available for an 
ssh login mayby someone could help out that way.

good luck,
Mark
