I purchased myself a 500GB WD Caviar Blue, about 2 weeks ago, to use as a backup drive and store data. I moved my personal folders from C:\ to D:\ and Created a secure zone (asz) at 100GB in size, and backed up my C:\ drive to it. This morning my PC booted up really slow, (usually it takes just moments as it's an SSD drive) I went to play some music and windows media player could not find the mp3 files. I looked in Windows explorer, and my D:\ drive was gone! in disk management Windows stated the D:\ drive was not initialized, and gave me a I/O error when I tried to initialize it. Running a third party disk program told me the whole drives sectors were damaged and unrepairable. I'm thinking Acronis did something, but I'm not 100% sure can anyone elaborate?
