Firmware update for 2.5” Micron C400 series Solid State Drives to fix Bluescreens and system hangs – ThinkPad, ThinkCentre, ThinkStation

ThinkPads Systems with Lenovo Branded Micron sourced C400 series 2.5” solid state drives (SSD) may experience Bluescreens, system hangs, crashes, or the drive may not be seen.


Any ThinkPad or ThinkCentre with a 128GB or 256GB Micron C400 2.5” solid state drive, or ThinkStation with a 512GB Micron C400 2.5” solid state drive. These drives were shipped with some T430, T430s, T530, W530, X230, and X230 ThinkPad systems. These SSDs are also available as options.

A Lenovo branded Micron C400 128GB, or 256GB, or 512GB 2.5” solid state d rive. These drives can be identified as follows:

- The 128GB drive's label will show a P/N of MTFDDAK128MAM-1J1.
- The 256GB drive's label will show a P/N of MTFDDAK256MAM-1K12.
- The 512GB drive's label will show a P/N of MTFDDAK512MAM-1K1.

Below is an example of a Micron 256GB C400 drive label:

All Operating Systems

Update the drive's firmware to resolve these issues. A new firmware has been released that addresses these issues as well as some encryption compatibility problems. For the 128GB and 512GB drive, the new firmware is 070H. For the 256GB drive, the new firmware is 08TH.

There are two versions of this firmware: a bootable CD version and a Windows executable. Regardless of version, any existing hard drive password that was set up in BIOS needs to be removed. If running any full disk encryption software (e.g. Bitlocker, Endpoint Encryption, PGP, SafeGuard, etc.) use of the Windows based firmware updater requires that the drive be decrypted otherwise the firmware update will fail. For this reason, it is recommended that users with encrypted drives use the CD version to update their drive's firmware since no decryption is needed.
Although the firmware update makes no changes to the data on the drive, it is recommended that a backup be performed prior to any firmware update.

Unzip and run Lenovo_08TH_Win8_SSDFirmwareUpdater.exe. View and
accept the license agreement.
- There is a specific file depending upon whether you have a 128GB
or 256GB drive and whether running Microsoft Windows 7 or Windows 8.
- Before running the program, save and exit any running
- Run the appropriate firmware update program for your drive. Upon
completion, the machine will need to automatically shut down and
reboot to complete finish the update.


1) For either method used to update the firmware, when booting back
into Windows, the operating system may say that new hardware was
detected and a reboot is necessary to complete the installation.
This is normal behavior after update drive firmware.

2) If the drive failed diagnostics prior to updating the firmware, it
will likely continue to fail after the update. If the drive still
fails, it will be replaced under warranty. Please contact Lenovo
support for replacement.
