I have WD My Cloud 3000gb.Pri start we always shines a red light and did not show to me or to a network you do not know what the problem is and is not working or reset .
See if the following link helps.
I have already formatted hdd
And what are you going to do now?
Use it as a simple SATA internal disk?
Put it in an enclosure and use it as a USB disk?
Attempt to ‘unbrick’ the MyCloud?
