So I have Win 7 Pro on my Mac, running it through Parallels 5. I was watching my class lecture online through IE and about 20 minutes in, it just freezes. I thought it was just a buffering issue but then I see "Not responding" at the top of IE. At that point, I couldn't do anything. I had Parallels in full screen mode, so I was completely stuck. After a minute or so I get a pop up error that says, "Unable to access Hard Disk 1. Input/Output Error." WTF?? I figure maybe just some glitch, so I forcibly shut down Parallels and relaunch it. After several minutes, same thing. So I shut down my Mac entirely and rebooted. Mac OS works just fine, no issues (no big surprise there). So I launch Parallels and launch Windows. Then I restarted Windows, just to be safe. Then I relaunch IE and Word. About 2 minutes later I was typing up some notes in Word and it freezes and I get "Not responding" at the top of Word. I forcibly shut down Parallels again, because it was just frozen and I was seeing the Mac pinwheel spinning (in Win full screen mode). Anyone have any idea wtf is going on? Anyone ever get this error or have this issue with Win 7 Pro (32 bit) in Parallels 5? I need some advice here!! Thanks for anything.
