Can someone Identify this

Appears to be a backplane/motherboard for a single bay My Cloud unit. The following post has a similar information the person indicated was on a sticker on the board which is similar to the image posted.

Thank you my friend.
So.it look like wd my cloud 1st get. Now.let me find a spare hdd to fiddle around

The posted link with similar model numbers appears to indicate it is a second gen single bay My Cloud board. If so the directions one would use to properly format and install the correct firmware would be different than those for a first gen single bay My Cloud.

First gen single bay My Cloud use OS3 v4.x firmware.
Second gen single bay My Cloud use either OS 3 v2.x firmware or the newer OS 5 v5.x firmware.

Before one tries to install the v5.x firmware to a second gen single bay My Cloud one should read through both the OS5 subforums and the OS3 subforums to see the many issues those with second generation single bay My Cloud units are experiencing. Several have opted to revert back to OS3 firmware due to the indexing issue that locks up their My Cloud rendering it unusable and due to the lost of certain features/apps that were not carried forward to OS5 from the earlier OS3 firmware.

For OS3 single bay My Cloud specific issues see the dedicated single bay My Cloud OS3 subforum:
