Thanks for your reply.
HD C & D: SATA 500 gb, Seagate
HD F: SATA 1 Tb, Seagate
HD E: SATA 1 Tb, Western Digital
All ones are internal and wired to main mobo chipset, not to AHCI.
No change after Rescan Disks from Action Menu.
I repeat that the problem about HD E arises only when I awake my pc from suspension.
