Adding 3tb Wd Red to My Cloud EX4100

Hello everyone.

Trying to add a (new) WD Red 3tb in the 4th, but led is solid red.

The drive gives an error code : 3
What can I do to make it work ?

Sorry for my mistake ! I have OS5. Thanks !

See the dedicated subforum for the EXSeries where users more familiar with the EX4100 may be able to assist.

Done !

Hello,

We recommend you kindly refer to the following KBA article (My Cloud: Solid and Blinking Red Power and Drive LED Status)

Hi Chris,
Thanks ! I know this article.
However, the problem seems to be a damaged (unused) WD Red 4tb disk
