depends traditionally 1GB = 2 ^30 in computland (1MB = 2^20)
however hard disk manufacturers (amongst others) started using GB to mean
the 'official' 10^30 (for reference at 10 GB the difference is a bit over a
full CD).
-> as a solution IEC invented binary prefixes:
2^10 = Kibi, abbreviated Ki
2^20 = Mebi, abbreviated Mi
2^30 = Gibi, abbreviated Gi
... (take the decimal prefix and replace the second syllable with bi of
binary, see [1] )
unfortunately this isn't yet used everywhere, which can give troubles as you
always need to be carefull and look up how you should interpret MB, [2]
gives a good overview of the current state of affairs.

of course it doesn't sound like the above explains the 4034 vs 4030, that's
a very weird difference
