Win XP Pro CD-R CD-RW

[Garry]

I don't have any additional CD-R CD-RW software
installed, just Windows XP Pro.When try to create my own
cd
drive shows wrong free space.I have cd with 700 mb of
free space but recording drive says 595 mb.This happened
when I disconnected recording drive and then connected it
back on.It worked perfect before but now it shows 595 mb.
I tryed with 10 different cd's same capacity of 700 mb
and it anyway shows 595 mb.Made restart -
useless.Reinstall device - same.I have removable drive
Sony Spressa CRX120E USB.Why Windows XP Pro does such
mistake and how I can fix it? Thanks.

That is overhead for the packet writing file system. Perfectly normal.

A: Filesystem overhead, and B: The difference between marketing
capacity that the HDD manufacturers use, and actual acapcity.

Things like the O/S and other programs may have consumed the 3GB space?
Is this a empty secondary drive or your main drive?

All hard drive manufacturers, in a deceptive attempt to make
their drives seem bigger than they are, define a GB as one
billion bytes, while the rest of the computer world, including
Windows, define it as 1,073,741,824 bytes (1,204 x 1,024 x
1,024). Do the arithmetic yourself, and you'll see that 37GB (in
the Windows sense of GB) is equal to 40 billion bytes.
