I installed windows 7 Pro x64 on a 128 GB Adata SX300 SSD yesterday (clean install after full format, SSD is brand new) and installed a bunch of programs and all available updates from windows update. Then when it tried to install SP1 for Visual Studio 2010, it failed due to lack of free space. Less than an hour before that windows showed I have ~60 GB free of the 119 GB on the drive, and now it shows ~2 GB is free.
I selected every folder and file (with hidden and system files showing) in the root of the drive and checked their size in their properties, it says they use 64.3 GB. I also checked it with Total Commander, it says they take up 71 477 304k and there is 2 764 476k free of 125 032 444k (I guess it asks the free space from windows instead of calculating it).
So it doesn't add up.
This is what I've tried to no avail:
- Run checkdisk
- Run defrag
- Run windows' disk cleaner (it found 2 gigs of temp files but nothing else big. I deleted them and the remaining space stayed about the same (!))
- Check for viruses with NOD32
- Check for spyware with Spybot S&D
Extra info: I've relinked my documents folder to another drive, but it's only 25 GB, so even if windows mistakenly counted that in, it doesn't add up.
Now I'm all out of ideas. What could cause this?
Thanks for your help.
Update: while I was typing this, windows reconsidered its opinion and now it shows 5,5 GB is free.
