I would also like to point out that the File system or File allocation table (NTFS / FAT /FAT32 etc) also taked up a large amount of disk space. Different file systems take up different amounts of space, file systems vary according to their purpose. The bigger the hard drive, the move space is required for these file systems.

Very nice explanation of a concept my hardware students have difficulty with.

Hi Leo, a great explanation thank you!

I am installing a new '160'GiG harddrive (system drive) and prior to formatting the drive it only has an indicated capacity of 130 GiG....

Does that sound about right for a drive rated at 160 GiG?

Is this a predicted "after formatting" capacity?

It seems like a large a discrepancy!

NB/ figures gained from windows XP setup disc.

130 seems a big short. I'd be suspicious that there was another partition on the drive eating up some space. Does XP's disk manager show only a single partition?

How did you "remove" them? Try emptying the recycle bin.

The 130gb limitation is due to lba limitations. Go here for help: http://www.48bitlba.com/

We have just bought an 80Gb Dell Inspiron laptop. The disk properties states total 69Gb, which it says is 74,***,***. I could understand if it said 80,***,*** was 74Gb, but how can 80Gb capacity be claimed for our drive which is 11Gb short?
