Wrong HDD size



-----Original Message-----
I´ve a 20 GB HD in my computer. In this moment my Windows
XP is tellin that I´ve 2,5 MB free, but I´ve deleted
already 150 MB.
How can I see the TRUE free space?
Megabyte Mystery
There are two common definitions for a megabyte (MB):

Ten to the sixth power or 1,000,000 bytes, the pure
decimal value.

Two to the 20th power or 1,048,576 bytes, a value
commonly used when indicating computer memory size.

Data Lifeguard, Data Lifeguard DOS and Copy files
consider a MB to be 1,000,000 bytes. This corresponds to
the values you get if you do a DIR command or run CHKDSK.

When viewing the properties on a hard drive under Windows
it considers a MB to be 1,048,576 bytes and it considers
a GB to be 1,073,741,824 bytes.

If you view partitions created by Data Lifeguard with a
utility that considers a MB to be 1,048,576 bytes, such
as DOS FDISK or Windows 2000/XP Disk Management, the
partition size presented will be a lesser number of MB.
The actual storage capacity is the same.

Example: If a drive has 1024 cylinders, 16 heads and 63
sectors per track, Data Lifeguard will show a capacity of
528MB. FDISK will show a capacity of 504MB.
