Hi I have a problem with my cloud 4tb
My mother accidentally pulled out the power cable and now the disk is blinking red light for many hours 10+ and I can’t find it on my network or ping it. The disk is working because it slowly vibrates. What to do?
Thanks in advance
Have you initially tried the 40-second reset?
If it a V2 mycloud , red can also signify no network connectivity.
Since you have not stated which generation of My Cloud you have, 1st or 2nd, I suggest you use this link, determine the generation you have and read the correct User Manual for yours.
1st generation has firmware version 4.xx.xx
2nd generation has firmware version 2.xx.xx
i have done it nothing happens, red led keeps flashing no restarting
i can’t access to the disk but i believe is 2nd gen because when it was working fine red light was showing when was no network connectivity
What are the LED’s on the rear doing? Are they working? If they appear normal then I suggest you shut it down for a while, long enough to cool, and then plug it back in and see what happens.
i left for a couple of hours to “rest” but when i plugged it still the same situation
back the leds from the lan are active orange and green seems that working
404 Not Found
but i think if i do this i will lost warranty

You already lost any warranty because it broke for your fault (or your mother’s). Anyway this procedure doesn’t need to dismantle the case, what it does is to boot a recovery from a usb stick and then it allows you to part the hd and upload a recovery into it, then you’ll upload the firmware and begin from scratch. I don’t see why it should break the warranty. Anyway it can even be that you broke the internal hd so if it doesn’t work (it worked perfectly for me) you will have to extract the hd, fix it or put in another one. You’ll know if your nas is gen 2 (v2 firmware) if its sn ends with 10

Anyway I can’t see why you were not able to create the two directories.
Try to do again all the steps, is the light flashing yellow/red?

Well, I’m not an expert but it looks like you fu**ed up the hd. Try the warranty card or you have to dismantle the box and see what happened. Connect the hd to a pc and see if it shows up, if it works, you broke the mainboard. But, I repeat, I’m not an expert.
ok man thanks for your help
i will take to the shop that i bought it
i hope that warranty covers me because i have it only 8 months 
I have a dumb question? If the disk is not listed. How is it that he can run blkid?
i had the usb flash drive that i booted the drive
Are you saying that you booted a PC using a USB flash drive that booted up windows? How was the
My Cloud device connected to the PC? I ask because if the My Cloud is not accessible from the PC
running windows it won’t be accessible from the PC running Linux. On Linux /dev/sda is always the boot disk.
OK So you booted the My Cloud from a USB drive.
