Hello everyone. I've just installed Windows Vista Ultimate Edition on my Desktop PC. The installation went fine and everything works correctly. However, I am getting these dialog boxes telling me that the HDD with Vista installed on is about to crash and that I should back up my PC. The wierd thing is that sometimes my other HDD somehow gets "disconnected" while the PC is running. I go to My Computer and the HDD that is going to crash is appearing but my good HDD has disappered! A restart always fixes the problem. My main question is why am I getting this HDD Crash error when my HDD worked great in Windows XP?!
