Unable to detect drive on HP Probook 6560b

UPD:

Chaged to SATA3 in BIOS. Now i see drive and of course the max speed cannot go over 260Mb fro read\write (as per ASSSD). Any ideas - issue related to HP BIOS or drive firmware in cinjunction with BIOS on thi sparticular notebook?

BTW tried to downgrade F.20 - no luck, speed as at SATA2. 

Some interesting thoughts: in hwinfo64 - chip rev B3, but on SATA AHCI controller shows B2, as per my undertsanding should be also B3… SATA AHCI controller claim speed support of gen3 6.0Gbps, but both ports 0 and 1 ports always in gen2 3.0Gbps mode despite any changes in BIOS…

Continue gaming with bios rev’s and settings, but pretty sure - there will be no success until HP bios update (or maybe HP + SanDisk FW) will be changed.

The disk itself is very good indeed…
