Recently reinstalled my computer with the final release of Windows 8, and to celebrate this, moved all the important data from my 2 pieces of 1TB HDDs (a Samsung HD103SI and a Western Digital WD10EARS-005B1 Green Caviar), converted both to GPT and Dynamic, and created a striped volume across the two disks. After this, I created an overlapping 2TB partition, for my downloads (storing Ubuntu images, my school DreamSpark installers, etc.).
It was working fine, until today, during a heavy P2P download of a Debian collection, the drive suddenly became unavailable. First I thought maybe some Windows bug, as it used to happen, so I rebooted. No, the drive was still unavailable, so checked it under Disk Manager. The so far perfectly working NTFS partition somehow is now unrecognized, RAW, and I cannot access my data.
Is there any way to restore the partition somehow? I have some very important data there, and it would be quite a cutback if I lost all those documents, not to mention the mass amount of (kinda retro or vintage) collection of old Linux installers.
