Seagate lost 28 gigs?

[Steeeeve]

This has probably been asked before but I can't seem to find it.

When I partitioned my Seagate 7200.8 SATA 250gb harddrive I did 50gb and 200. However, when formatting the 200 it says I only have something like 283 or 273 (i cant remember right now). Anyway, what happened to the rest of the harddrive!

You're going to lose a bit due to the way the manufacturer does the math.

My 40gig is actually a 37 gig.

The bigger the hard drive is, the more you will lose.

Manufacturer GB = 10^9 = 1,000,000,000 bytes
OS GB = 2^30 = 1,073,741,824 bytes
So basically you lose 73MB per GB. So 250*73 = 18250. So you lose ~18GB.


Feel free to correct me if I'm wrong. I'm almost never right when it comes to math.
