Hardware size: 27.9 GiB (30GB) Hover Tooltip: Hardware manufacturers
usually use GB marking. GiB is maximum amount of data a GB marked
harddrive can fit.


You have connected 30GB harddrive, Open it up available space 27.9
GiB, Free space 27.5 GiB.

If you use compressed file system (I thought i so somewhere a bzip2 file system)

You have connected 30GB harddrive, Available space Appox. 50.4 GiB,
Free space Approx. 49.3 GiB.

ps. just noticed you have asked about flash-drives, well they are in
GB - GiB ranges now so the example is over-optimistic but still
aplicable to flash-drives ;-)

Good link which compares both scales and has notes of where what is.


I was surprised Google Calculator only supports base 2 data units with
incorrect SI prefixes.....
