Missing Memory?

If you actually ask for info on the drive it'll show the capacity as 149GB or so.
This is due to HD manufacturers using 1000megabytes/gigabyte when calculating GB as opposed to the "correct" 1024megabytes/gigabyte. Here, (160GB/1024)*1000 give you a value of 156GB. There is also a slight loss due to formatting space (usually about 5% or so, at least in NTFS systems, not positive with HFS+).

Side note: "memory" usually refers to system memory. "storage" refers to hard drive space, which you are talking about. Some people make the mistake because they're both measured in the same units of measurement-- bits, bytes, megabytes, gigabytes, etc.
