If you do a search for “unbrick” in this subforum you will find numerous discussions on various ways to prepare a new hard drive for use in the single bay My Cloud enclosure. Including the [GUIDE] Upgrade a working My Cloud to a bigger HDD (easy steps) discussion directly below this discussion on the subforum’s main page. User Fox_exe’s directions are one popular method of configuring either an old drive or new drive for use in the single bay My Cloud enclosure. First step is to ensure you have a second gen single bay My Cloud. Check the P/N number on the bottom of the single bay My Cloud. If it ends with “-00” it is first gen v3.x/v4.x firmware. If it ends with “-10” it is second gen v2.x/v5.x firmware. The methods used to unbrick each version are different. One cannot use the second gen directions on a first gen single bay My Cloud.
Note: The My Cloud and My Cloud Home are not the same device. If one has a My Cloud Home DO NOT use these directions. The directions and files below are only for the second generation single bay My Cloud.

It is generally a good idea to do a 40 second reset or a System Only reset in the My Cloud Dashboard > Settings > Utilities after the initial unbrick of the My Cloud before one begins configuring it or copying any user data to it. Sometimes one may have to perform the unbrick process more than once before it works properly. If one see’s a red front LED after unbricking the My Cloud try to access the My Cloud Dashboard, if one can access the Dashboard then do a System Only reset or a 40 second reset.
