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 upgraded to the latest version and enabled overprovisioning. Then I restored my system partition.

Everything works fine, the only thing is that I can't enable the write cache in device manager. This had been working with the old firmware version.

Any help?

Bryan M - Based off your findings, we suggest uninstalling your current version of FNet HybriDisk. We are expecting a new HybriDisk release within the next week or so that will have added features and compatibility that should help correct this issue.


cleanwater - Have you been following the FW tutorial PDF in the link above? If not, please take a look as it may answer your questions.

If you have and continue to have issues, contact our Tech Support team at info@mydigitaldiscount.com and they can assist you in troubleshooting.

I have a Lenovo T540p with Windows 7 Pro.
Try Firmware upgrade 1.6 to 1.7 but failed...
Firmware dose not starting...
Can firmware be updated from this state?
Bryan M Monday, May 12, 2014 06:07:37 PM
I upgraded the firmware to 1.7 (and followed the instructions exactly.. they were very helpful) because my system crashed during a restart and gave me the following error message before launching into chkdsk and windows recovery after that.


However, after I upgraded the firmware using the instructions my computer doesn't run nearly as quickly. I looked at the policies for the cache drive and noticed that the option "Enable write-caching on this disk" was unchecked and beneath that box it said "This device does not allow its write-caching setting to be changed."

I'd love to get this working again but since that error I have gotten constant reminders to run chkdsk. Although I keep running it, the reminders don't go away and my computer won't run near as quickly as it did before the first time it crashed. Any help would be appreciated... I was in awe at how quickly everything worked before the troubles started.

Bryan M,

To update your firmware, yes - the WINPE version will work for you.

When it comes to firmware, if your SSD is installed and working to your satisfaction then you don't necessarily need to update to the latest version. However, we would suggest that everyone OP their drive for the optimal performance and longevity.

FNet HybriDisk software formats and partitions the drive for you. To confirm that it's running properly, simply click the FNet icon in the system tray on the bottom right of your screen. Doing so should display the operation information.

I have a Lenovo T540p with Windows 8.1 and am trying to figure out a way to install the firmware but there aren't instructions for that... or do I just follow the instructions for a Chromebook and use Windows PE?

I just want to use it as a cache drive. I plugged the M.2 drive in my computer, installed FNET HybriDisk, and told it to run in enhanced mode. Do I need to format the drive at all? How do I know it's running correctly?

Rolling back FW is never suggested. We're hoping to have a new firmware update available to download by next week, if not sooner. We currently have the new version in hand and our Tech Support team is putting it through comprehensive in-house testing to make sure issues like yours have been corrected before we release it.

Keep an eye on the @MyDigital Twitter feed for notification when the new firmware update is available to download.

Hello, apparently I am having the same problem as Alex and simon.
I just got a replacement of the SSD and it is not working on AHCI mode, unfortunately I cannot use it on compatibility mode. There is any possibility to downgrade it, maybe to FW version 1.5? Or there is any forecast of when the FW 1.7 will be available? Thank you

Alex - Yes, there have been a handful of customers with this issue. Good news is, our Tech Support team is currently testing FW version 1.7 and we're hoping it will shore up any remaining glitches.

Follow @MyDigital on Twitter for notification of all future FW updates.


zed - Yes, the S9FM01.6 update will work for your particular 60GB Slim 7. There was very little change from FW 1.5 to 1.6 so if you've already installed the drive and have no issues with it's performance, updating the firmware is not totally necessary but you're more that welcome to if you prefer to have the latest version.

Hello. I just received my first MyDigital SSD from Amazon.com and need your help with determining if S9FM01.6 is a correct firmware update for it. Thank you.

I ordered the following: www.amazon.com/gp/product/B00B3WX3SA

The sticker on the unit I received displays SKU: MDS7-BP4-060

Under linux, smartctl reports:
Device Model: SC2 SATA SSD
Serial Number: FEB4073B1EB2000*****
Firmware Version: S9FM01.5
User Capacity: 60,022,480,896 bytes [60.0 GB]
