DMA is not supported on the CRD-8400B, it is in the kernel nodma blacklist (drive_list_entry drive_blacklist).Reading the list I see stuff like :
{ "Compaq CRD-8241B" , "ALL" },
{ "CRD-8400B" , "ALL" },
{ "CRD-8480B", "ALL" },
{ "CRD-8480C", "ALL" },
{ "CRD-8482B", "ALL" },
{ "CRD-84" , "ALL" },Does it work when this appears as substring ? I guess not, else CRD-84 would be enough...
