I have the same problem and registered here to look for help to solve it.
My hard drive is Excelstor Technology J880 (ATA), 80 GB. It is split in two partitions - D and E.
I have no problems with E.
On D my folders (plus hidden and system) are 28,4 GB.
But when I right click the drive and select properties it shows USED SPACE: 40,3 GB.
Almost 12 GB more!I have disabled sytem restore.
What could be the reason? I did error-check and defragmenting but they didn't help.
The article from the microsoft site is unclear in the most crucial place.
It says:
"2. From the Edit menu, click Add Value."
And nothing more.
But on the Edit menu I have New - Key, String Value, Binary Value, DWORD Value, Multi-String Value,
and Expandable Sting Value.
Microsoft help, really.
So, could you please help, anyone?
P.S.: And it is not Virtual Memory that is the problem, I checked and it is not enabled for this drive.
