Hi there,

I have a Mediasonic ProBox H82-SU3S2 8 Bay External Hard Drive Enclosure.

"smartctl -a /dev/sd[a-h]" returns full stats of all drives when connected via eSATA using port multiplier. However, when connecting via USB 3.0, the same command does not work.

I get the error: "Smartctl open device: /dev/sdd [USB JMicron] failed: No device connected".

So, I try various combinations of the "-d usbjmicron,X" parameters but still cannot get any smart status of the hard disks. 

Any one have any luck with this unit on USB 3.0? Anything I can do to test/help get it working with smartmontools?

To those wondering why I don't just use eSATA, I have a new computer whose on-board eSATA port does not support port multiplier.

Thanks a lot!

Graham
