I have a secondary disk drive 465GB as reported by Windows explorer.
I'm going to install a secondary O/S on it, so I moved EVERYTHING on it to another drive.
Windows explorer STILL reports 9.27GB of used space on the 465GB hard drive!
Windows file explorer shows nothing on the disk, and I've turned "Show hidden files" ON.
What could possibly be taking up 9.27GB of space? Is there a tool to see what is going on?
+1 for the MFT, didn't think of that. 9 GiB sounds pretty much for the MFT. But that might depend on how many files there were on it before. – Joey – 2009-07-24T21:45:02.150
Yeah, the MFT does reserve a lot of space. But it's very pessimistic, and automatically shrinks if you need the space for something. The MFT doesn't use most space marked as MFT, it just reserves it for potential future use. – kquinn – 2009-07-24T23:28:15.113
