I have 2 My Cloud devices (2 and 4 Tb) and both were switched off before I went on holiday - both were working perfectly before this. On returning and powering on, the 2Tb model went to blue light within seconds. The 4Tb model now never goes beyond the “flashing yellow led” stage of bootup. On powe…

Thank you for your reply. My understanding was that doing the 40 second reset would result in ALL data being lost - is this correct? - you seem to suggest that the data was still there after doing your reset procedure. Can you confirm please? - I have a lot of data on this drive that I can’t affor…

[image] Dunvegan: My understanding was that doing the 40 second reset would result in ALL data being lost - is this correct? No, not correct. You DO NOT loose any user files/data when performing a 40 second reset via the reset button on the back of the My Cloud. Please see the following WD Su…

Thanks for asking! I looked up the user manual just to verify myself Page 64: System Only: Changes all settings back to the factory default values, makes private shares public, and returns the administrator password to none. Your content remains untouched and intact. Note: You can also do a sy…

Thank you for your help and your experience - greatly appreciated!! One question - “it take some time for the MyCloud to initialize itself” - how long?? - I have done as you said and am now getting Solid white → Flashing yellow but still no Blue light - though there is lots of disc activity that th…

So I have tried various combinations of powering on and off, holding the reset button for 40 seconds and for up to 5 minutes - I have done all of this fully clothed, partially clothed and now completely naked - none of this works! - I still get the flashing yellow led and no blue led. Can I now saf…

Well, if it’s the NIC that has failed, which does sound likely, it’s a hardware failure, and no amount of unbricking will help (well, I suppose the driver could have been corrupted). The best you are likely to do is to recover the HDD and use it as an internal or external drive. Just for completene…

Thanks for your imput. I have a 2Tb MyCloud connected to the same router so I’m assuming that the router is OK. It works perfectly with the Synology NAS too. Also, the faulty unit doesn’t get to the blue stage when unplugged, so I’m assuming that it’s gonna end up in the skip with my other 3 WD My…

Yeah, if the router’s working okay for other devices, it certainly does look like the one device is duff. I guess for completeness, you could try unbricking, just in case it is simply the driver that’s been damaged somehow (although the critical stuff like that ought to be protected by the RAID arra…

Sorry for getting back to you that late…and you got a Synology NAS, which is obviously better than WD NAS. Anyway. The HDD seems failed to me and it needs “unbrick”, which involves crack open the enclosure, plug into a PC to recover data if possible. Then restore it with MC image (try search somewh…

Not necessarily. Apparently there is a possible way to unbrick a My Cloud without removing the drive from the WD encloure.
