Comment 8 for bug 160015

Another boot and this time gparted sees both drives attached to the SATA drive. Gparted is very slow to do anything though. Took a long time (more than 5 minutes - I left it then) to scan devices.

Getting repeated errors in kernel log:

Appears to me that although sdc is seen now, the system doesn't like it! Keeps resetting and reconnecting.
