I tried everything to set my seagate microdrive as FIXED, but nothing!!

I can install with no problems the OS and some programs, but some other softwares can't see or work with removable drives, and mine is! There are some tools to set CF cards as fixed but they don't work with microdrives. Asked to seagate support too, but they say they don't give support for this issue. I think i need a software to flag as fixed the drive, maybe on the firmware (because i erased all data on the disk few times and is still marked as removable)

Somebody who had success??

any suggestions appreciated
