Inaccessible local disk randomly appeared in Computer Window
I noticed the oddest thing this evening. I recently noticed that a new, inaccessible Local Disk, with the drive letter Q:, appeared in my Computer window. When I try to open it, Windows tells me it is inaccessible. When I look at the properties, the disk, there is 0 used space, and 0 free space. The hardware tab reports that it is my system drive, but for the life of me I cannot understand why this has suddenly appeared as an inaccessible, size-less hard drive in my Computer. I tried to check this drive out in Disk Management, but I'm only seeing my rescue partition and my primary partition. No other hard drives are being reported. Does anyone have any idea what the heck is going on here?

Found the answer. The Culprit is the Office 2010 Beta (specifically, Softgrid): http://channel9.msdn.com/forums/Coffeehouse/498323-Mysterious-local-disk-Q/ What's weird is that I just installed it on a second computer as well, and I don't see the drive there. Guess that's why it's still in Beta!

I have the exact same mysterious drive...and it is on both computers that I have installed the 2010 beta on. However, I just installed the beta a few days ago and I thought I had that drive letter before that, though I could be mistaken. The 2nd computer had the program installed from a usb drive using the "office to go" feature. I wish MS could tell everyone about things like this and explain what its purpose is rather than making us spend hours trying to troubleshoot the issue.Thanks for running down the answer!JoRene
