"Storage titan Western Digital has warned owners of its My Cloud NAS devices to update to the latest firmware immediately.
In a support post, the company explained it will soon pull support for old versions of My Cloud OS, the operating system on which My Cloud external drives run.
From January 15, devices compatible with My Cloud OS 5 (the latest version) will no longer support prior generations. Owners of these devices will need to update in order to continue to access their data remotely, and receive security updates and technical support.
On April 15, meanwhile, WD will pull the plug on all but the latest generation of My Cloud OS, at which point owners of older, incompatible My Cloud drives will only be able to access their back-up data locally."
