Hard Drive Not Detected as 160 GB

I recently purchased a Seagate 160 GB Hard Drive and installed it in my USB Bytecc External Enclosure. I formatted the drive as NTFS with the Seagate Utility CD. The utility shows me that I've formatted the whole drive (160 GB). However, whenever I use the drive on my Windows XP laptop and my Windows 2000 PC, the hard drive shows up as 149 GB. Is it just me or should I be seeing the drive as 160 GB? Why won't the additional 11 GB appear?

My Windows XP Laptop has SP1 and SP2 installed. My windows 2000 PC has SP 4 installed. My PC can recognize a 120 GB hard drive that is currently in there as 120 GB. The problem could be with my external enclosure, but it supports up to 300 GB and there is no support available on the Bytecc website. I've used Window's Administrative Tools and the hard drive still shows up as 149 GB and no additional partitions.

What can I do to have my hard drive show up as 160 GB? Or, is there no solution?
 
yep. 1024bytes=1kb
1024kb=1mb
1024mb=1gb

you lose gb due to ntfs/fat32 formatting.
my 160gb drive has 1 142gb partition and 1 6.95gb partition
 
Thanks guys. That helps a lot. Should've known that. I assumed since the drive was not part of the actual system, it wouldn't need slack space. Oh well. Thanks again.
 
you don't lose 7.5% of your disk space to slack space.

The manufacturer defines 1 GB as 10^9 or 1,000,000,000 bytes (Giga decimal)

Windows defines 1 GB as 2^30 or 1,073,741,824 (Giga binary)

160 GB x 1,000,000,000 / 1,073,741,824 = 149 GiB

 
For marketing purposes drive space is defined in Millions of Bytes (makes them look bigger).
While Computers have historically used the binary megabyte (2^10 Bytes), which is about 5% larger in bytes. When you get to GigaBytes (2^20 Bytes), the differential grows to about 7%. That is where your Bytes went - marketing.

.bh.
 
my 5gb shows as 4.68 =( couldve atleast got me @ 4.88gb lol. But ya most HDD's are 20gb= 18gb and 30gb= 28 and so on. It sucks but its a money marketing gimmmick
