After a couple of weeks of messing about trying (and failing) to sort this problem out I need a solution. Just moved to using a Mac. Installed 'Office for Mac', works great. My external hard drive will not co-operate with the different systems. Meaning I can't add and remove files from the drive as I would like. I have endlessly searched Google and the gereral consensus is 'format the drive as FAT32'. Tried this (again) last night. It took 2 hours and then told me that 'the volume is too large for FAT32'. The external hard drive is an Iomega 250gb drive and I need it to work between the systems (PC and Mac). Please help!
