Help text

Enable tagged command queueing unconditionally on drives that report support for it. Regardless of the chosen value here, tagging can be controlled at run time:

echo "using_tcq:32" > /proc/ide/hdX/settings

where any value between 1-32 selects chosen queue depth and enables TCQ, and 0 disables it. hdparm version 4.7 an above also support TCQ manipulations.

Generally say Y here.
