Is it possible for the disk test to only test 2% or 5% of the disk drive and be able to end a cycle? The objective is to get EMC scans of the system doing read/writes and spin-ups and spin-downs. With todays drives, a full scan takes way too long. This might be achieved with a repartition to a smaller drive partition, but I prefer to not do it this way. Is there some percentage setting somewhere to do this?
