So I was importing files that were saved on this HDD to Adobe Premiere Pro to edit multiple videos. Everything was running pretty smooth until I was previewing a WAV file on Windows Media Player while editing a video in Premiere. WMP and premiere went on a not responding strike and it went this way for a good 30 minutes. I tried Alt + F4, nothing. I tried shutting down the programs from Task manager, still nothing so I figured that I should restart my PC. After that everything seemed to work fine. This morning before work I went and edited more footage then it did exactly the same thing. Restarted the computer and went to work. When I came back tonight, the computer's startup time was way slower than usual and the hdd's shortcut to my desktop displayed a big, blue question mark. Restarted the PC, went into the boot menu and saw that my motherboard recognizes all my drives but then when I went back to my Desktop, the shortcut still displayed the same image and I can't see that particular drive in Windows Explorer. I've had 1 failing drive warning from Windows 2 weeks ago but I solved the problem. The HDD is a Western Digital 320GB that was installed in a 2006 pc professionally then removed and installed 3 months ago in a 2010 PC by me. What can I do so that Windows recognizes it? Is it possible to keep all the data that's on there and how can I retrieve it? Also I need a NAS (network attached server). Tired of opening my case when I want to add more drives, got anything to suggest?
