Hum, i remember to have the same feelings.
I just play a while with the Dell under winxp and format, and debian under 
x86 (on the dell).
Since it recognise well the hdd under the dell computer, i can make my fs 
ext3 on it and i got no problem after on the Sun.

Here more infos from my sun & the hdd

#> cat /etc/fstab

<pass>

I did it a while ago, and in a rush time ;-) so i don't remember "exactly" 
what/how i did right, but the idea is here.

Hope it helps.

Take care
