The SMART log shows that 0xea was a "FLUSH CACHE EXT" (not "EXIT", duh..) command, which is what libata issues when it wants to ensure that all cached data has been written to the drive. This particular drive is reporting that it doesn't understand the command. Peculiar that, because all modern large drives implement it. What does hdparm --Istdout give for that specific drive, and then again for one of your three "good" drives ? Cheers
