PR4100 freezes

I found an issue with the PR4100 when I plug in a 1TB Samsung 840 EVO SSD into the back of the unit. Whenever I do this the PR4100 freezes and I have to turn it off an restart it.

I tried this same drive plugged into the back of the DL4100, but I did not have the same issue.

Any ideas? Is this a known issue?

Hi there,

Does the same happen with another external unit? I would also like to know the file system that this unit has.

Unplug the USB (UAS) external drive from the USB port of the My Cloud PR unit
