My WD Blue 10JPVT 1TB HDD gave me an error 22 with no explanation upon reboot. Fortunately I have a image burned to a 650GB HDD so I swapped them out and continued using the Laptop (Sony Viao SVT15115CXS) without much loss. I put the broken drive in an enclosure and immediately did some basic tests. It shows under Computer (Win. 7 Pro), has up to date drivers and is listed as functioning properly in Device Manager. I can read and write to it. It just won't boot! WD support could not help me return it to factory settings. If anybody out there that has much more technical than I (and I'm sure there are many) could help I would be eternally greatful. Apologies for the lengthy description but I wanted to be concise, yet descriptive. If you need any further information please only ask and thank you in advance for all your help.
