Recently any time I try to copy large files (400 MB+) to or from my 2TB My Cloud device, it just dies part of the way through the transfer. It will disappear off the network, the power light on the front goes off but the activity lights on the NIC are still on. The only way to fix it is to unplug the power, plug it back in, wait for it to initialize/scan and try again. If I copy a few smaller files, it works just fine but if I go for a larger file again it locks up.
I’d love to know if there’s a log somewhere in the OS that I could look at to try and figure out what’s wrong. I just enabled SSH on it for the first time (haven’t needed it in all the years I’ve had it) and I was looking at /var/log/messages but nothing stands out.
