How to solve SED problem in 2,5" WD drives

  • We have already changed the connection type from USB to SATA (using a compatible SATA PCB or SATA adapter), but when we start Marvell utility we see SED locked error.

1. Start the drive in Kernel mode: head isolation with connected spindle contacts
or short E47 PCB pin to the ground (tested on 2060-771961-000 REV P1). Status registers will be off, ID is not detected, but autodetect should work correct.

2. Follow Work with ROM->SA regions editor->Do it now.. button and Block SA access.
