This is a result of two different standards being used for defining what the “Giga” in GigaByte means.
The decimal standard used on the packaging is:
kilo = 1000 , Mega = 1000 kilo, Giga = 1000 Mega
The binary standard used in Windows is:
kilo = 1024 , Mega = 1024 kilo, Giga = 1024 Mega
The amount of space on a blank “4.7GB” DVD is slightly over 4,700,000,000 bytes which by one standard is 4.7GB and by the other standard is 4.38GB.
Attempts have been made to get people to use new binary prefixes for the binary standard, e.g. ki = kibi = 1024 , Mi = Mebi = 1024 kibi, Gi = Gibi = 1024 Mebi, but this hasn’t been very successful so far.
The capacity of a blank DVD would be 4.38 GiB using the binary prefix standard.
i heard about overburning, but i fear of it damaging my drive, duel layer disc cost as much as 10dvd+rs here in my country, so that’s not an option.
please help, i own winxp sp2 with liteon 1693s
Your LiteOn 1693S cannot overburn DVD media.
The LiteOn 1693S can overburn CD-R media, but it cannot overburn other media.
will i damage my drive?
No, but your burn will fail when it reaches the stated capacity of the DVD if you even manage getting a program to attemptthe overburn, but more likely the overburn wil just refuse to start.
