Hi there. So It all started off when I was getting an error message when I tried to sync my Ipod to my laptop. I took it to the apple store and they told me to create a new itunes library. I did that and my computer was being slow and unresponsive. I did a hard reboot. Now when I try to turn on my computer all I get is the noise, the logo, and the spiny gear thing. I tried putting it into safe mode but it wouldn't work. If i have to wipe my HD is there any way i can retrieve data. Thanks!
