Someone help me please! I bought an External Hard Drive yesterday, to help share files between my Mac (os9) and my PC ... When I 1st plugged it into the PC, it appeared and seemed to work fine. But the Mac wouldn't recognise and asked me to format it. So I did as DOS and then it popped up fine on both, except for being 42gb instead of 320gb. So I reformatted as Mac 0S9, and it works perfectly on the Mac as 298gb. But now I can't get it to appear on the PC! It appears (on the PC) in the device list as USB Mass Storage, including on the desktop toolbar to disconnect, but I can't work out how access it, or get to it to try and reformat! It was specified as PC only, but the shop said it should work on both fine, (and I checked I could take it back and change it for a Mac & PC one). I'm wondering if it, or any other I might change it for can't work with both os9 and XP? Any suggestions or help... Anyone?
