Not too long ago I got a copy of Server 2012 from one of the student programs at my university. I decided to use it as an opportunity to learn a bit more about Server as well as setup an HTPC. That probably wounldn't be the OS I would normally go with, but since I had it I gave it a shot. Everything went off without a hitch. I was able to utilize the storage spaces to combine about 8 TB worth of drives into a virtual disk.
My system ran like this for a while. I mounted that virtual disk to X: and so I had my C:and X: drives.....C: being utilized as a boot drive. It was partitioned and the rest of the space was being used in the 8tb storage space and mounted to X: This has been running for about 4 months without an issue. I was using this server as central storage for all the PCs in the house. This morning I was downloading files to it using Sabnzb and I noticed that Sab would pause. after reading some logs it showed that it got a CRC error. At first I thought Sab was talking about the files that I was downloading, but then I noticed other files also started to have the same issue. I determined that this was an issue with a storage device somewhere.
I rebooted my server and when it came back up some Windows updates were coming down the pipe. I let those finish and when I logged in and went to my computer, my C: and X: drive was listed but the X: drive showed no data. As if no drives were attached to it. I opened up Server Manager and took a look at the "Files/Storage" role and I saw a list of the drives. All of them showed healthy. I'd go to the Volumes section try and run a scan but it would just fail. Its as if all of a sudden all my data is gone but the drives are showing healthy. I know this seems like a really specific issue and I even find myself having a hard time explaining exactly whats happening, but I just wanted to see if this issue sounded familiar to anyone else.
