My primary suspect is power supply problem but things like this are hard to prove. With the merged speed down fix, libata will do the right thing after a few errors, so ignoring the problem wouldn't be a too bad idea. If you're curious, you can try to connect drives to different SATA ports and power lanes and see whether errors follow the disk, port or power lane. -- tejun
