What symptoms do you have with the blown diodes? So far I have seen a 32GB SSD Expresscard, shows ID but no access to data, recovered this by removing NANDs - it has simple UT163 controller, 2 Samsung SSD drives, 64GB and 128GB, both fail to ID but customer requested these back before I could work with them, and a 128GB Kingston SSD. This shows ID but no access. Will work on this one today or tomorrow.
The diode issues seem to result in no access to the drive at all, and I mean no drive ID or anything. On the first couple of cases I got in, I just sat down with my multi-meter and tested each component. My customer on this Crucial 256GB drive is getting impatient, so I may not have time to figure out exactly what the problem is there. Same thing though, drive is not recognized. It will recognize when I flip the switch to flash the firmware, but even then it's not recognizing properly, just the raw id from the ROM.
