Continuing on a thread as I did not find any more details..
I got an internal ZIP drive from work (Z100ATAPI) and this should be compatible with my EMAX HD Rack if trusting the database.
And as my internal original HDD does not work - the question is if I can "just switch" the HDD to this ZIP-drive as it is an internal one? I guess it probably isn´t that easy, so if anyone have experience with this I would love som input!
Thanks Niklas
