Folks- I've ran into about 4 or 5 people that are having issues when their system crashes due to two types of hard drives on their systems. I never recommend using IDE and SATA on the same computer. Use one type or the other. While most people will be able to get both up and running and perhaps not have any problems, when there is a crash or serious system error, XP will default to IDE and write OS data to the IDE drive. This is turn, renders the computer unbootable as XP "sees" two OSes on the same system on 2 different drives and gets confused where to seek data. solution: easy - use one type of drive or the other or make your IDE external. Take your IDE drives and make them portable USB drives. While this is a costly solution, it is much better than having to go through the headache of file recovery and reformatting drives. I've gone through this issue myself and it is a royal headache. Most of the time it is damn near impossible to access your data again as the file tables get jacked.
