I powered off my wdmycloud for about 2 months and now I cannot get it started. I can hear the HD tried to start but failed and the LED turned red, anyway to rescue my data?
The rear 4/40secs reset button not helping? Red led is bad:
The following faults trigger this state: • Disk SMART failure • Data volume does not exist • System volume does not exist • System thermal shutdown (75° C)
If you have no recovery experience, contact WD Support for RMA.
I finally solve it by myself using the following steps:
Changed a power port. I think there are something wrong with the old port and the voltage is not stable.
Starting while holding the reset button.
It took a while for it to start, I guess it’s checking the hard disk. Then I can finally access my files. I also tried to update the firmware, no problem.
