Managed to get the SDXC 256GB card to "superfloppy" state with "NO UNALLOCATED SPACE" and 1 partition showing in mbrwiz. with the correct type partitian signature?? 0C-FAT32X
Steps:
1) Hard Disk Low Level Format Tool quick wipe ( remove partitions and MBR)
2) guiformat
mbrwiz /list showed 0 partitions. So could not set it to 0C-FAT32X
3) Fat32 format with GParted on usb stick. (no option to set "flag")
4) MBRWiz finally could change partition ID. see below.
C:\Windows\system32>MBRWiz /disk=11 /part=1 /type=CH
MBRWiz - Version 3.0.83 for Windows
