It was pointed out to me that PC Hard Disks (tend) to wear faster, I think they mean one factor is that the PC HD is used by the machine a more than a RISC OS machine does. (I personally wouldn't know - but others say to me these things). :unhappy: Other major factors as you pointed out - such as temperature, an obvious point I was not aware of as to the importance of cooler running RISC OS machine (not forgetting QUIETER)! Also from what you are suggesting, it really pays to renew your Hard Drive before it ages or is due to 'run to the ground' (die!).
Thanks! :cooldude: Steve
