Hi Mark, Its an embedded device whereby the one HDD I have does not work with the Marvel PMP. I have the command to send to the PMP controller but I am not an officianado with linux SATA(the code I have is from VxWorks) The drive is confirmed working, but the PMP chip does not default to SATA Generation 1, and this HDD is a bit dumb to figure it out :) - so I have to force the PMP controller to Gen1 mode. (I have tons of drives that work just fine, its just this ONE Maxtor drive that is being a pain) The short - I need to write a command to the SATA controller before this HDD can be recognised. Much appreciated, Richard
