i have just bought a freecom 500gb hard drive told that it was readable and writable on both pc and mac platforms. i have used other externals like this which were used first on pc and are formatted as MS dos Fat 32 and they work with my mac. however, my drive has been used on mac first and is formatted as mac os x journaled. i did not format it though it was automatically done like this. i have lots of stuff on it and need to transfer to pc. is the only way to reformat drive as fat 32? also when the drive is used with a pc it comes up and makes a noise etc and in the taskbar it says the device is working properly.but in my computer it is not there and cant be found. any help greatly appreciated. thanks.
