Tja BlackTiger dat is niet mijn schuld hoor.
Insert a 4.7Gig DVD-RAM disk (though is ~4.3 Gig in computer size) in the DVD-RAM drive and as root mount it:
The problem you're having is that 4.7 gigs is not 4.7 gigs. It's really about 4.3 gigs. This has to do with the definition of a gigabyte used between techs and actual English speakers. Techs say "gig" but mean 1.024 billion bytes. English speakers say Gig and mean 1 billion bytes.

Why do I only get 4.37 Gigs of data on a 4.7 Gig DVD?
There's an unfortunate confusion of units of measurement in the DVD world. For example, a single-layer DVD holds 4.7 billion bytes (G bytes), not 4.7 gigabytes (GB). It only holds 4.37 gigabytes. Likewise, a double-sided, dual-layer DVD holds only 15.90 gigabytes, which is 17 billion bytes.
The problem is that the SI prefixes "kilo," "mega," and "giga" normally represent multiples of 1000 (10^3, 10^6, and 10^9), but when used in the computer world to measure bytes they generally represent multiples of 1024 (2^10, 2^20, and 2^30). Both Windows and Mac OS list volume capacities in "true" megabytes and gigabytes, not millions and billions of bytes
Most DVD figures are based on multiples of 1000, in spite of using notation such as GB and KB that traditionally have been based on 1024. The "G bytes" notation does seem to consistently refer to 10^9. The closest I have been able to get to an unambiguous notation is to use "kilobytes" for 1024 bytes, "megabytes" for 1,048,576 bytes, "gigabytes" for 1,073,741,824 bytes, and "BB" for 1,000,000,000 bytes.
This may seem like a meaningless distinction, but it's not trivial to someone who prepares 4.7 gigabytes of data (according to the OS) and then wastes a DVD-R or two learning that the disc really holds only 4.3 gigabytes!
Zo dan is dit misverstand ook weer de wereld uit.
