I'm new to this forum and I was just wondering why is there a change in the amount of physical and virtual memory in a computer.
For example, I recently purchased a 320GB hard drive. When I set everything up, the amount of memory displayed is 288GB. I have become aware that this also occurs on iPods, USBs, and any kind of device with memory. I know that this is a naturally occurring phenomena and I can't do anything about it however I am just curious why this occurs.

Teraphlate, When we allocate the file-system for example FAT,NTFS, EXT2,EXT3 etc (you can call it as a constant space alloted on the drive to put the system sequentially in a perticular manner e.g. somewhat like a book-rack in your room) then that data regarding file-system(the book-rack in room) is also needed to be stored on the hard-disk along with the data of the components attached to that system. More the hard-disk, larger will be the space taken by the file-system to devide whole drive in chunks for data storage and hence more disk space is used. Each drive has the concept of File-System whether that is a Hard-Disk or a Pen/Thumb Drive. Cheers :)
And you will have another surprise coming. If you run Vista, the system will write a shadow (restore point) at least once per day. That is about 1GB per shadow. That will go on until it has filled about 45GB's (15% of your C:\ disk). So don't be amazed if you loose disk space rapidly in the next days. But once it reaches 45GB's, it will start reusing that space. You have plenty of disk capacity. There is no need to worry.
