One can “shuck” the My Cloud hard drive and attach it, using a USB to SATA adapter or a spare SATA adapter, to a computer that is running Linux or a Linux driver to see if they can view the drive contents and then copy files off the drive.
In some cases certain hard drive SMART errors are enough to cause the My Cloud to halt loading a drive. The drive is still readable if one pulls the drive and attaches to a PC running Linux/Linux driver.
Plenty of videos on YouTube on how to “shuck” a single bay/single drive My Cloud enclosure.
