Most likely, the 1.25GB is eaten up by a mathematics exercise:

Hard disk manufacturers like to define 1 GB as 1000 * 1000 * 1000 = 1 
000 000 000 bytes.
Operating system manufacturers like to define 1 GB as  1024 * 1024 * 
1024 = 1 072 693 248 bytes.

Therefore, if a hard drive is speced at 30 GB, that means 30 000 000 
000 bytes. Using 1024 per K, that gives us:

30 000 000 000 / 1 072 693 248 = 27.966 GB

Which could be an explanation to where your 1.25 GB's went (the 750 MB 
discrepancy I can't explain :).

Yes. :-)
