HDD showing incorrect free space, wasn't last night!
Hi,
I just signed up and this is my first post, I have checked into this already but I'd figure I'd send my issue out here and maybe someone has an answer.
My system specs:
i7 920
Asus P6T SE
6GB ram
Hitachi 4TB 7K4000 (Storage/back up drive)
WD 2TB Caviar Black (OS drive)
WD 2TB Caviar Green (back up)
ATi Radeon HD 3870
Don't think they are quite necessary but there they are, now my issue basically started last night/early this morning. My 4TB drive (3 weeks old) had about 1.38TB left of free space, I was using about 2.3TB on it of different things, now it is showing up as only 448KB of free space! I checked different forums online and it could really seem like a number of things, which I have tried but no luck yet, last resort is moving things off and format the drive.
I actually noticed that some of my video files last night would not play at all in any video player, but they were working fine literally several days before, btw last night the drive was showing correct space too. Now the only difference is that I re-installed Windows a few days ago and something happened to my 4TB drive since certain files were not playing, mainly all newer files and conversions were the ones corrupted.
So, I ran the error checking in Windows last night and let that run overnight, when I awoke I noticed that it had finished (did not take a snapshot - wish I had) and there was no issue with the drive according to the report, it showed correct space free. I also noticed during the recent installation of Windows, while booting and installing, a couple times I saw the "error checking" go through before booting up Windows, I had not seen this previous times installing Windows, but it always finished and showed the correct space and always for the same Hitachi drive, never for my Caviar Green or Black.
After running the error checking last night, my Hitachi drive basically lost all it's space. Now here's where it gets weird or tricky in defining the issue. I grabbed WinDirStat and ran that, it shows the same info as Windows, 448KB free of 3.6TB, when I click on my 4TB in WinDirStat to go to the second window, it shows nearly 100% usage, but says 2.3TB in space!
So this is where I'm scratching my head, Windows and the first screen of WinDirStat show the same info, 448KB free of 3.6TB, then when I go into my 4TB drive through WinDirStat, it shows nearly 100% usage of 2.3TB??? This is half correct, it should show 2.3TB being used but not that it's 100% full, I'm just confused here, why in one screen does it say 100% full of 3.6TB then in the next screen it says 2.3TB 100% full.
I also enabled hidden files, deleted the trash bin of that volume, but nothing. I literally cannot see what is taking up 1.3TB of space that I had available last night. I think manually running that error checking screwed it up somehow and why certain files have just stopped playing, I have no idea.
So any help would be great, the drive is new so I'm hoping that it's not failing already, but could be, since that was the only drive to automatically go through error checking during win7 installation. If anyone has any idea, how I can locate these hidden or corrupted files and what I can do or what I can delete, that would be greatly appreciated.
Oh last question, if I do end up formatting this drive, should I do a quick format or full?
