Time out of ATA Command Report
The Time out shows the NCQ time out. It is applicable for only NCQ commands. A
threshold can be set in the "NCQ commands Timeout Threshold", the default value is
1000 sec (the user can change it to any value). The statistical report provides a "Time
out" report based on this threshold. Any NCQ command that takes more than the given
threshold is flagged as "yes", which means that a timeout occurred for that command.
