Hi , first post here . I've a Mac Desktop and iBook I want to backup - I've also just bought a PC because I wanted to try some CAD software that wasn't available for OSX and it has a biggish hard drive that will be going spare. Can I clone the Macs to the PC hard drive and use it as an external hard drive for backup purposes? I realize I wouldn't be able to open the files on the Windows machine but would it work in other respects ? Thanks
