Question about drive capacity

I hope this isn't too stupid. I just installed Vista on a new Seagate 320G
HD. I have an identical drive that is being used for backup and additional
storage. When I go into Disk Management, Vista says the boot drive is 20G
smaller than the data drive. Each drive is just one big partition. Any idea
where the 20G went?

Re: Question about drive capacity

No offense, but I'm looking for an answer, not speculation.

Re: Question about drive capacity

Is this one of those "The drive says 340 gigabytes on the package but
installed it only says ..." questions?

Re: Question about drive capacity

A binary gigabyte is 2 to the 30th power, 1,073,741,824 bytes.

Manufactures use a decimal gigabyte, 1,000,000,000 bytes or 109 bytes.

So the size reported by the computer is 7% less than the manufacture's size.

Re: Question about drive capacity

Yes, it is. Drive manufacturers overstate the capacity of the drive by
rounding to 1,000s instead of using the accepted 1,024 values that are used
by Windows and folks who are precise.

Re: Question about drive capacity

Nope, that's not it. Let me try one more time for clarification. I have two
320G Identical Seagate drives installed. C: contains the operating system, D:
is just an NTFS formatted drive. Vista says the capacity of C: is 280G. It
says the capacity of D: is 300G. Now I understand that because of the way
capacity is calculated, that the drives will be less than the manufactures
specifications. However, they should still be the same. I'm trying to
determine why they are different. My BIOS sees identical drives. The Seagate
tools sees identical drives and capacity, but Vista does not.

I used Diskpart.exe to examine the dives, and they don't appear to have any
additional volumes or partitions. So... Why the 20G difference?
