hi, just swaped my M500 SED-enabled drive from Lenovo X220 to 2570p. 2570p detects drive correctly, in BIOS i can see that drive locked, but I don't get password prompt for SED drive during boot. My BIOS version is "50", i try to randomly switch a couple of related parameters, with no luck. I just get "No OS found" error. What can help me, why 2570p isn't prompt for password. Thanks. edit: Try to use upgrade bay, no luck Next i reinstall SSD in X220, disable drive encryption (with blank passwords), than enabled again OPAL in 2570p. Now it worked as expected.
