Hi Bigal. I guess you're new here and not too familiar with the search feature we have here. Play around with it, you'll find lot's of information on that topic, it's been covered in other posts to great detail. I am doing the same tonight, but I know what my partition scheme will be (also on a 30 gig maxtor).
4 gig for win2k (advanced server ntfs)
the remaining boot sector for Debian (divided into linux native and swap)
7 gig ntfs
10 gig fat32
and the rest fat32 for a network drive.
Of course, my point here is that this is good for ME.. but probably won't suite your needs, so you gotta be more specific. Still though, try the search feature. Good luck.
