In case you are in the wrong forum, the My Cloud Home (MCH) is the more recent personal cloud storage device which WDC introduced around the June of 2017 and it is a perfectly rectangular box, without the rounded front that is associated with the earliler generation of My Cloud (MC) storage devices. With its introduction, the MCH case was also manufactured to a tighter tolerance and it is no longer feasible to wedge the unit open by sliding a slim edge or card into the seam of the unit. Instead, one or two 1mm holes can be drilled to the depth of 1 mm on one side of the casing and a pin inserted to deform the clip to release the bottom silver case. The exact measurement is 6 mm from the seam between the ivory top and silver bottom case and 39 mm from the opposite ends (please see photo). Prior to pulling the case apart, remember to remove the 4 Phillip head screws hidden under the two gray rubber pads on the bottom silver casing of the MCH. Only one side of the MCH needed to be drilled, on the side opposite from the hard drive and the upper and lower case should pull apart relatively easily after the internal tabs depressed by pins.
Please note that all warranty is void when a hard drive is shucked from its casing when it is done without the authorization of WDC. Please note that one does not have to shuck a MCH in order to find out the identity of the hard drive inside, please see the SMR link below for instructions to identify the hard drive and possibly file a claim.
The primary reason one would wish to shuck a MCH is that the hard drive in the the MCH is most likely a SMR (Shingled Magnetic Recording) drive (series WD?0EFAX) and is unsuitable for use in a network connected environment and in many cases SMRs are not suitable even for desk top use and should be relegated to archival purposes such as write once-read many times archives. As shown below, under certain test conditions, the performance of random writes in the MCH private space can be 0.0 MBps, to say that that number is not satisfactory could be an understatement.
To understand why it has come to this and why allegorical ‘when the walls fell’ for some MCH users, one has to understand why the identity of the hard drive in the My Cloud Home was never published by WDC. WDC may have it posted somewhere internal to their company, but it was never revealed to their customers. Many customers would have likely avoided the MCH had they known they were buying a SMR drive.
