Bug Description
Something causes the drive to basically
freeze up and become unresponsive when it tries to suspend. It looks
like it may be caused by the USB reset right before it tries to sync()
the file systems. I've tested another USB hard drive I have and there is
no USB reset messages before it syncs the file systems.
When I suspend the system, it sits for 15-30 seconds on a blank screen
before it actually starts the suspend process. That long wait only
happens when this drive is attached. And upon resuming the drive
disappears from the system and is not accessible because the drive is
basically in a frozen state.
I never had this or any other problem suspending with this drive
attached in previous Ubuntu releases. It worked perfectly in Intrepid
and Jaunty so this is a regression in Karmic.

Does thaht also happen in non-JMicron mode, with "sudo skdump /dev/sdc"? libatasmart does not seem to use jmicron mode for your particular drive.
