Kernel bug (not saying it is here, just that it's always a possibility).
The reason I haven't made that assumption is that the previous 500GB disks still work fine.
If they're USB 3 drives as well, then that would tend to suggest it isn't a kernel bug. If they're USB 2, then one could suspect a USB 3-specific driver issue.
Any idea how to easily report on USB power usage?
No, but try mount -t debugfs debugfs /sys/kernel/deubg and then look at /sys/kernel/debug/usb/devices
