This appears to be a different problem. Something is issuing SMART-related commands (smartd or smartctl perhaps) which the drive seems to be reacting strangely to. It apparently completed the command but never raised DRQ to request any data being transferred even though we expected it to. Maybe SMART is disabled on the drive and that's causing it to just toss these commands? CCing linux-ide in case anyone knows what would cause this.

Here's smartctl -a for this drive - same output for both sda and sdb. Smartd is currently running. Any advice appreciated.

Sounds like SMART is likely disabled on that drive. You can try doing "smartctl -s on /dev/sda" and see if that will turn it on.


Sorry - that last post of mine was brain dead. Here's the one with (hopefully) useful data.
