Just recently set up a Raid 0 via two Maxtor Diamondmax Plus 9 120gig SATA drives. I partitioned it with Partition Magic as a single large partition. When I right click on the drive and choose properties to view the pie graph it shows 70-something megs of "used" space. Granted it's only a drop in the bucket for 240 gigs but the drive is completly empty....what could that 70megs be?!

OS Overhead (such as the file system tables)

It's also marketing. Systems measure a kb as 1024, while the advertising/marketing department measures it as 1000 kb. Combine this with the tables, as Edward indicates, and you have your lose.

Cool thanks guys!....eased my woe. :)
