Os formatos de armazenamento RAID (além do espelhamento simples) são normalmente proprietários - eu recomendaria emprestar temporariamente um Mac para ler os dados da matriz.
Opa, só notei que você quis dizer espelhamento de RAID 1! Isso é estranho. O software RAID deve ter escrito metadados estranhos para as unidades, o que não é típico para espelhos.

One, many RAID cards store meta data at the front of the drive, usually the first 128 sectors of the drive are reserved for the RAID card to use. Information like drive state, time of last boot, size and other information that is important to the RAID card is stored there If, however, the RAID card is not the primary hardware interface but instead a standard IDE port then the BIOS has no way of interpreting vendor specific data. In other words the BIOS looks at sector zero in the boot sequence, tries to find a Master Boot Record, then execute any boot it may find. The problem with this drive is that the MBR is 128 sectors down the drive since the meta data is stored in that area. Knowing this, we can trick the BIOS into skipping the meta data and pointing right to the OS boot record.
