Data recovery service? No, I am not talking about sending one’s My Cloud to a paid data recovery service company. I am talking about things the user can do at home on their own with a little bit of time and learning (if they don’t know Linux commands), and the use of a USB to SATA adapter (or similar) if need.
If one hasn’t done so already, try performing a 40 second reset using the reset button on the back of the My Cloud to see if it resolves the front red blinking LED.
How to reset a My Cloud device | WD Support
One troubleshooting step, if one previously enabled SSH in the My Cloud Dashboard, is to attempt to access the My Cloud using SSH. If one is successful in doing so one may be able to copy their user data from the My Cloud to their local computer (using WinSCP for example or using Linux command line copy commands). If one has a second generation v2.x firmware My Cloud (P/N number on bottom of unit ends with “-10”) one can try, as a troubleshooting step to use Telnet to access their second gen My Cloud. One can use the forum search feature (magnifying glass icon upper right) to find past discussions about trying to use Telnet to access a My Cloud.
If one can successfully access their My Cloud using SSH they can issue this command:
smartctl -H /dev/sda which will return some S.M.A.R.T. information about the My Cloud hard drive, which may show if there is a problem with the hard drive itself.
As a last resort, when all other troubleshooting methods fail, one can remove the hard drive from the My Cloud enclosure (search YouTube for example of how to do so) on their own. Connect that hard drive to a computer using a USB to SATA adapter (or similar device/spare SATA port). Then using Linux, Linux boot disk/boot USB flash drive, or third party Linux drivers attempt to recover their data from that drive (if one hasn’t been backing that data up to an external USB hard drive). If the firmware on the My Cloud is corrupted one can use one of the various unbrick methods in past forum discussions or at user Fox_Exe’s site (Fox_exe file archive) to restore their single bay My Cloud firmware. Note: the directions are different depending on if you have a first gen (v4.x) or second gen (v2.x) single bay My Cloud. If the My Cloud hard drive has failed or has physical disk errors one can replace that hard drive with a new hard drive (not an SSD drive). The various unbrick methods or user Fox’s directions can be used to properly configure a new hard drive for use in a single bay My Cloud enclosure.
