Flash firmware on a Micron OEM SSD (P400m)

  • 772

I have a 100 GB Micron P400m SSD from an EMC VMAX array. The sector size is 520 or 528 bits. I can identify the drive with everything via the tools from Micron, but it refuses to download the firmware or even upload.

Is there a way to re-flash it with different firmware? I know Crucial or Cisco products of containing the same SSD drive allow such firmware updates.

Edit: additional information Apparently there has micron MTFDDAK400MAN-1S1AA that has 512b blocks. I have here micron MTFDDAK400MAN-2S1AA that has 520b blocks.

Is there anyone who could do a firmware dump from the micron MTFDDAK400MAN-1S1AA or perhaps where to download a 512b firmware for it?

  1. If taken out from an EMC array, it is very probable that your SSD uses a custom (or at least rebranded) firmware. This means that Micron/Crucial standard flashing tool can not work, requiring EMC's own utils/firmware.

    Finally, please consider that not all SSDs support sector size changing (unless the vendor provides special utility to do that).
