Thanks, to both of you, for your comments... I'm learning here! I am still searching for a "new", larger HDD, but with the information provided here I now know that I can expand the search to cover also HDD's intended for (or shipped with) 360's, 750's, 755's and 760's. Also, thanks very much for the information about the 8 GB limit; never had heard about that. By the way, does this limit mean that a larger HDD, say, born with a 16 GB capacity, won't be usable at all? If getting a, say, 16 GB drive, is it impossible to just somehow format it to be a 8 GB device?
Final thing: Does anyone here know how to clone my existing 540 MB HDD (now in the 755CE)? Is it sufficient simply to copy all the files from the old 755CE HDD onto a new (if I manage to get on!) and larger HDD, or won't that work? Are these issues with boot sector, MBR, MFT etc. which needs to be properly located in specific sectors on the HDD etc. like in newer versions of Windows?
Thanks for any additional hints about actually where to find me a "new" larger HDD for my old '755CE!
