Hello!
I have several Intel SSD DC 3700 Series drives.
100GB, 200GB and 400GB and all have firmware 5DV12270.
100GB and 400GB drives work fine but the 200GB SSD works only in SATA2 mode with the same ports (SATA3) and cables (SATA3) with which the 100GB and 400GB drives work as SATA3 mode.
What could be the problem?
