I have experienced the same bug with a Hitachi hard drive (HTS545050B9A300).
In reading the specification of my drive, I came across this interesting paragraph relating to NCQ: The host shall not issue a legacy ATA command while a native queued command is outstanding. Upon receiving a legacy ATA command while a native queued command is outstanding, the device aborts the command and halts command processing of outstanding native queued commands. It seems to me the kind of thing that might be responsible.
