Can I use my cloud drive as a secondary drive.?

Hi guy

I own a Mycloud drive with OS 3 which I have been told that it will no longer be supported for updates so I was wondering if I bought a new drive like my cloud home or mybook nas drives, will I be able to attach the old drive to the new drive via usb like a normal external drive?


Look at the User Manual, Chapter 12.
My Cloud Personal Storage User Manual (

You would need to know what other WD product you are going to buy and what it is capable of doing.

I plan to attach mine to my desktop computer and continue to use it as storage/backup.

The OS3 My Cloud devices that cannot be updated to OS5 will continue to operate for local network access. It is the remote network access through WD’s servers that is being terminated along with firmware support.

My Cloud OS3 End of Service

Q: Will my device stop working if I can’t upgrade to My Cloud OS 5? Will I lose access to my data?
A: Once the services have been shut down, you will still be able to access the device on a local network. However, access through the My Cloud OS 3 mobile app or web app will not be possible. Email notifications also won’t be delivered. Devices that have auto-update enabled will receive a final firmware update to disable remote access and outbound traffic to cloud services. Then, support will end and you’ll have to use the local network to access the device.

Yes, one can extract the hard drive from the single bay/single drive My Cloud enclosure. One can then use a USB to SATA adapter (that supports 3.5 inch drives) to connect the My Cloud drive to another device. Note however that the My Cloud hard drive is formatted for Linux (EXT4). If one was expecting to read the data off their existing My Cloud drive one will need to use a device or software driver that can read EXT4 formatted drives. Otherwise one will have to re-partition and re-format the My Cloud drive (once extracted) to work in the new device. Re-partitioning and re-formatting will result in loosing all existing data on the drive. So backup the drive if planning on re-partitioning and re-formatting.

If you need a network attached storage device (NAS) then avoid the My Cloud Home line of devices. Those devices are not really NAS devices. Likewise the My Book Live drives are also not really full fledged NAS drives. There are a number of NAS manufacturers out there in addition to WD. Synology and Qnap are the other major brands of NAS devices.

No you can’t connect the old drive to the new drive. But you can connect them both to your network and then copy back and forth between them.

Please can you tell me how to connect to my desktop and continue to use as storage? I did try to connect it to my desktop but couldn’t find it? I’m not a techi (64 years young) but loved Mycloud. Thanks in advance

See my topic on this.

You’ll need the IP address and Netmask.

Any reason you don’t want to just leave it connected to your network along with any new NAS you buy? You’d have two NAS on your network then, and could copy freely between them.
