Here’s an interesting circumstance that happens every single day and drives people nuts…they can’t squeeze 4.4Gb into a standard regular DVD+R or DVD-R disc bought from the shop down the street. I had the same problem, and in a matter of minutes…discovered I was one of the millions of folks practically dumbfounded…deer caught in spotlights.
OK. You wanna know? It’s a marketing conspiracy…see if you agree.
“Disc manufacturers assume: 1 GByte = 1000 x 1000 x 1000 bytes, but computer software normally assumes: 1 GByte = 1024 x 1024 x 1024 bytes. So 4.7 (disc manufacturers claim) GBytes = is actually = 4.38 (computer software claim) GBytes”
A DVD+ single-layered data disc has 2,295,104 sectors, each holding 2048 bytes = 4,700,372,992 bytes. The salesmen among us call that 4.7 GB. You could call that a decimal measurement.
If you’re talking in binary measurements, a megabyte MB =1024 x 1024 bytes = 1,048,566 bytes, and a gigabyte GB =1024x1024x1024 bytes. Under this system of notation, that 4700372992 bytes becomes a tad over 4482 MB, which when divided by 1024 becomes what the scientists among us would call 4.3776 GB.
Some countries use labels like kibibyte (KiB), mebibyte (MiB), gibibyte (GiB) for binary measurement, while others name the same units kilobyte, megabyte, and gigabyte consecutively.
Ahah. So, that simply means that your 4.7Gb DVD blank is only capable of 4.37Gb storage space!!! We’ve been shortchanged!
DID YOU KNOW THAT? It sure makes me mad as hell!
The funny thing is, you might need to get some math done to figure out if your operating system was designed by a scientist or salesman!
