Can you guys continue the tests on the "dead" M4? Is it possible to use the official firmware update iso image burnt to disc to boot the computer and recognise the disk at all? When I accidentally deleted the firmware on my M4, I was able to force a re-write of the firmware to my M4 after a power cycling fix. I remember the parameter was -a to delete the firmware, then I power cycled it, and used parameter -u to force re-writing the firmware.
However I'd like to see another type of test, i.e. does the nand flash show significant volatility, once the MWI is exhausted? I'd like to have several SSDs of different brands/models to reach the MWI threshold then left powered off for a week or so and see if the contents are lost. By this we can know whether the "MWI Lasted" is indeed the best value to calculate the endurance.
