Estou mudando meu servidor Windows para o Ubuntu e estou tentando fazer com que meu software RAID1 (espelho) que criei no Windows seja exibido no Ubuntu. Eu li que isso é possível aqui usando o mdadm, mas estou tendo problemas.
Aqui está o que estou tentando:

Failed to read last sector (5860544511): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
or it was not setup correctly (e.g. by not using mdadm --build ...),
or a wrong device is tried to be mounted,
or the partition table is corrupt (partition is smaller than NTFS),
or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/md0': Invalid argument
The device '/dev/md0' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
graeme@MediaCentre:~/Desktop$ exit
exit

Eu obtenho a mesma coisa quando tento 64 partes, e se eu listar os discos na outra ordem.
Alguém sabe o que estou fazendo de errado aqui?
Edit: estou adicionando os resultados do fdisk -l, conforme solicitado por Paul:
