RECORDING ANNOYANCES

LOST DVD SPACE

The Annoyance:

I'm writing to a 4.7GB DVD-R, but I only see 4.38GB of free space. What gives?

The Fix:

Ever work with hard drives? Well, hard drive vendors often use "decimal" gigabytes (1,000,000,000 bytes) to denote capacity, while software makers apply "binary" gigabytes (1,073,741,824 bytes). So, when you examine the disc with a typical software utility, a 4.7GB DVD disc may actually appear to have just 4.38GB (4.7/1.073) of space available. There is no "missing" space-it's simply a different way of expressing the disc's capacity.
