Okay, I have Windows 7 Pro (64-bit). My notebook has two physical hard drives. My first hard drive is fine. My second hard drive isn't. I have 110GB total on that second drive.. I detect 46GB being used, manually through highlighting and selecting, and confirmed through the system utility program WinDirStat. Windows says 104GB is actually being used. I'm missing about 58GB. What the heck? x_x Accessing my administrator account does nothing.. even after I enable SHOW HIDDEN FILES.
Threads don't generally get deleted around here. Would it not be better to explain how you solved this issue, in case anyone else has the same problem? Even if it is just to say - OK, I was being a noob... BECAUSE....
I have a simmilar problem where a whole 200GB partition was missing in windows 7 even though a 150GB partiton on the same drive was fine but it turned out that windows hadn't assigned a drive letter to everything that need it therefore the one partition wouldn't show. A quick trip into drive management can easily show problems like new drives which need initialized or drives that need a drive letters assigned.
Okay. I once tried installing Ubuntu but I screwed up and accidentally formatted my secondary drive. Luckily, the format was a QUICK FORMAT and only removed the table header. I had my only copies of my Anime Expo 2009 photos on there and needed to restore them. So I found a program called TESTDISK which can restore deleted/formatted data. The only thing is, since the header is gone, everything no longer has a filename so upon recovery they all get renamed a sequential string of characters. Anyhow, I left this folder of recovered files on my secondary hard drive where they were originally. As I moved on, I started storing other files in that hard drive, but outside that TESTDISK recovered files folder. For whatever reason, Windows detected my hard drive as 104GB used, but when I selected folders or files myself from the drive and checked file properties, I only see 46GB used. Well, for whatever reason, the TESTDISK recovered folder isn't counted depending on where you get the disk size measurement from. I promptly deleted a huge 56GB .DEB file in there and moved on. Success! There you go. Be careful of where your files go and how they're saved.
