I need to buy an internal hard drive for an external casing. I know it takes enhanced IDE, but am not sure what ATA/100 versus ATA/133 means. Will both fit ? Is one faster, better, etc ....
....Also, I should back-up data on DVD's, which seem to take about 4.5GB of info, but I heard somewhere that some DVD's have two layers and you can get TWICE as much on one DVD. I have a stack of DVD-R's.....will they work ?? How do you know which ones will do this, and do you need a more fancy DVD burner than I have, or is it in the software you use to burn DVD's ??
