Samsung 850 Pro not recognized ? about sedutil HOT 5 CLOSED

I checked if I connect my Samsung directly to Sata2 ports on my motherboard( asus p6t se) instead of marvell sata 3 ports of my controller - detection is working ok

So it looks like there is problem with my Marvell 88se9230 controller not allowing to detect opal disks ??

Ok!
I managed to turn on opal and upload pba image(LINUXPBARelease-1.10.bin) to my samsung 850 pro using sata 2 controler(build on my asus p6t se board). Next, I switched disk to my marvel 88se9230 controler to sata 3 port and it boots and giving PBA prompt and I am able to boot.

So using Marvell marvel 88se9230 controler I cant use sedutil software, but I am able to do PBA and work on that drive.

There is also one error I cant explain. After I enter password the PBA linux prompt is giving me error: ERR: Identify failed Invalid argument. Next the PC reboots and is booting normaly to OS using encrypted disk. So it works but I dont know why these error is showed.

It looks like the Driver for your Marvell controller is blocking the OPAL commands. Did you try using the Rescue Disk to configure/query the drive while it is attached to the Marvell controller? The LinuxPBA* and Rescue systems are Linux based and should use the standard Linux kernel driver for the Marvell controller.

Hi

1. Linux Rescue Disk is detecting my Samsung 850 Pro on marvel 88se9230 controler. So it looks like it is marvell windows driver related bug.

2. ERR: Identify failed Invalid argument. - is related to USB pendrives when I put sedutil-cli --scan on linux rescue disk/or during LinuxPBA auth.

There is currently no support for USB attached drives. It's on the list of things we'd like to do.
