Synopsis: Click here to download the latest firmware update for MyDigitalSSD solid state drives featuring the S9 controller (SC2, SB, SBe) along with step-by-step upgrade tutorials for users of all experience levels. (Updated 3/20/15)

To better assist our customers, the My Digital Discount Tech Support team has created new step-by-step tutorials to assist MyDigitalSSD owners in upgrading the firmware on Super Cache 2 (SC2), Super Boot Drive, and Super Boot Eco (SBe) solid state drives featuring the Phison 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 MyDigitalSSD drive 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 their 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).

42mm (2242) Super Cache 2 (SC2)

42mm (2242) Super Boot Drive

mSATA & mSATA Mini (Half-Size)

Two things I need help with MDM242-SC2-128:

1) WIN10 bld 2004, unable to enable write-caching policy. I remember it worked under WIN7. Any reason why the message is now: "Windows could not change the write-caching setting for the device. Your device might not support this feature or change the setting."?

2) I started at FW v1.7. I tried to update to 2.1. It didn't work. When I enabled over-provisioning, it seemed to have updated the FW to 2.1, with an 120 GBs of storage available (down from 128 GBs). I then accidentally over-provisioned again and now instead of 120 GBs free, it reports 113 GBs free. Any way to reverse the over-provisioning?
Hi Trevor,

1. Are you able to reformat the drive and use it normally?

2. The 113GB capacity you're seeing is the normal usable size of a 120GB SSD.

William Yingst,

Hey there, sorry to hear you are having issues there with your Super Cache 2 M.2 SSD. Please email tech@mydigitaldiscount.com with the info from your comment, and include what you can: brand, model number, form factor capacity, firmware, device OS, device motherboard

Just bought a brand new 128GB Super Cache 2 42mm SATA III (6G) M.2 2242 NGFF SSD. Unfortunately, I can't get it to be recognized by any software, including this program. The BIOS does not pick it up, and neither does my file system or even this firmware upgrade tool! I would be able to use my brand new drive!

For reference, my motherboard is an MSI H110i pro, and I have it installed in the only M.2 slot.

I just flashed a MDM242-SB-128 from 1.8 to 2.1 and it's now taking 2 minutes to initialize (before my BIOS comes up, or my PC attempts to load an OS). I can then see it in my BIOS, but not in any OS, including WinPE via your firmware utility or diskpart. Advice?

I had to RMA a Superbootdrive from amazon, due to it showing up as a Physical 20MB disk, rather than a 16GB SSD. Th replacement looks good, but it has firmware version S9FM02.6 on it. I have another SSD with S9FM02.1 firmware. Your latest version appears to be S9FM02.1, is there an update pending or something?
