I'll be buying a new computer soon to replace the one I've had for nearly 5 years (p3-800). This computer has served me well for most of the time except for the hard drive (40gb) which has bad clusters on it. I had to format it once and it nearly didn't format due to the bad clusters (kept displaying error messages). This has led me to believe that the component most likely to fail with any computer I get in the future will be the hard drive (I don't mess about with any of the other components as a general rule). To overcome this problem (and all the expense and inconvenience that a failed hard drive causes) I've been thinking about buying a new computer with 2 hard drives. I don't use much space (considering the size of hard drives these days) and I thought I could use the first hard drive for the first 2 or 3 years then switch over to using the second hard drive for the next 2 or 3 years (after which time I'm sure I'll be thinking of a new computer again). Is this a good idea, or don't things work like that ie. if 1 hard drive fails then it won't even be possible to boot the computer or something, also do hdd's degrade over time anyway regardless of how much they are used. Would appreciate some advice! Thanks.
