Here are several things you could try:

1. this patch: http://patchwork.kernel.org/patch/24790/ - it has fixed two
similar bugs already.

2. Also, try connecting your hdc and hdd devices with an 80-conductor
IDE cable (those with the blue connector on the motherboard side) and
see whether that fixes the problem.

3. send the output of 'hdparm --Istdout /dev/hdc'

Thanks.
