This is a very common situation.
The issue is that there are two established definitions of what 1 GB means.
Hard drive manufacturers usually define 1GB as 1,000,000,000 bytes.
Most operating systems define 1 GB as 1024 x 1024 x 1024 = 1,073,741,824 bytes.
Divide 1,000,000,000 by 1,073,741,824 and you get about .931
.931 x 80 GB =74.5 GB.

There is no missing storage space. It never existed.

Yeah, LMiller7 is correct.

For example, my USB thumb-drive claimed to have 4GB of space, but it turns out it was actually 3.72GB.

If you have the hard drive that full you have a problem. Windows won't even defrag a partition with less than 15% free space. Eventually your partition may become unusable, even if you don't add more files.

You need to off load some files. Do you have backups of your important files?

cobol stated that he had 75GB of free space... not 75GB used.

I did read the thread wrong. The OP states that Windows only sees 75GB. Doesn't state how much free space he has. Couldn't be 75GB if Windows is installed. That said, thanks for correcting me.

pls, some company chose to lie to custumers, then they make 1GO based on decimal system (b=10), but for sony and the phonix bios, they restrict to science rules wich mean they applies the binary system (b=2) 1go=2^10+2^10+2^10=2^30
