Synopsis: Download the latest firmware updates and step-by-step upgrade tutorials for MyDigitalSSD Super Cache 2 mSATA and M.2 NGFF solid state drives featuring the S9 controller in this very post! (Updated with FW Ver. 1.7 on 8/11/14)

To better assist our customers, the My Digital Discount Tech Support team has created new step-by-step tutorials to walk MyDigitalSSD owners through upgrading the firmware in Super Cache 2 (SC2) 50mm mSATA and 42mm M.2 NGFF solid state drives that feature the S9 controller.

The updates found at the bottom of this post serve two purposes:

  1. To upgrade the firmware of an existing drive
  2. To over provision while upgrading the firmware of a drive

If you have an Super Cache 2 SSD running at full capacity and plan to keep it that way, DO NOT run the Over-Provisioning version of this update. Doing so will over provision the drive and there is no going back.

With that said, MyDigitalSSD HIGHLY recommends users to over provision Super Cache 2 SSDs when using them as system drives for maximum drive performance and longevity.

WARNING: Please check your firmware version before downloading and installing any firmware update. If you have a numerical version of similar or higher value to the latest update, you will not need to upgrade.

If you do not know how to check your firmware version. View our quick and simple tutorial on "How to check your SSD firmware version" (PDF, 442KB).


WARNING: The firmware updates found in this blog post are ONLY to be used with the following MyDigitalSSD Super Cache 2 solid state dive model numbers:

50mm mSATA


25mm mSATA Mini (Half-Size)


42mm M.2 NGFF


MyDigitalSSD, nor My Digital Discount, will be held responsible for any loss or damage occurred by using this update with any drive other than the MyDigitalSSD Super Cache 2 series SSDs listed above.

I had exactly the same problem on Y510p as Simon (message from March 30th, 2014) after firmware upgrade for the purpose of turning OverProvisioning to ON only, as my SSD (128GB) came with 1.6 firmware. After OverProvisioning was turned ON, bios could not see the drive until I turned AHCI OFF in bios. Called tech support and sent email on their request with all the details of the steps executed. Did somebody have success with turning OverProvision ON with BIOS already at v.1.6? Bios upgrade allows OverProvision to be turned ON if it is OFF with firmware at version 1.6, but after drive is already at v.1.6 and OverProvision is ON it is not possible to launch firmware upgrade or make a change to OverProvision state.

Jiayi Yang,

Below is a link to the Lenovo Forums where other customers had issues installing M.2 upgrades. They may be able to better answer your question.

The other day, MDM242-SC2-128 was purchased.
Although X240 was equipped "2101 : detection error on ssd1" (M. 2) is displayed.
SSD cannot be recognized.
What should I do?

Unfortunately, it sounds like you will need to return the drive to RamCity for a replacement. Force flashing the firmware is unlikely to have any effect but you're welcome to try before returning it.

I'm having the same issue, firmware failed to update half way through and now drive capacity is 0GB. I live in Australia and purchased it from a retailer, RamCity.
I feel like if I could force flash the firmware then all would be good, any recommendations?

It sounds like something went wrong during the update, like a spike in power or something running in the background may have disrupted it. In any event, you will need a replacement. Please email info@mydigitaldiscount.com with your original order information and we'll set you right up with an RMA.

The ssd I got came with fw 1.6 so I just over provision. Everything works ok until the program ask me to recycle power. When my T440s restart, it reports: 2101: detection error on ssd1 (M.2) and my 128G m2 ssd is now missing.
