I'm thinking of using the 60Gb Maxtor 6YO60L0 from my PC (it's only been used for around 9 months), because according to a guide on digitalspy(http://forum.digitalspy.co.uk/board/showthread.php?t=156344), they recommend the Maxtor 6YO80L0 (which seems to just be a slightly different size at 80Gb) and it means I can upgrade my PC drive to something with 8Mb cache. Does anyone think it's worth the effort to do this? Will I notice moving from a 2Mb cache HDD to an 8Mb cache on my PC? If so, do I just do a standard format of this drive I'm going to use from my PC? Perhaps I should just do it the easy way and buy a new one and use THAT for the Sky+ box to save all the messing around...?
