I have a APS DDS 3 external unit. Can't get more than 10 gig out of it. Native should be 12. Retrospect shows hardware compression enabled in the storage set but in the script the box for software compression isn't grayed out like it should be. This indicates that hardware compression isn't really working.
Called APS and they are useless. They keep saying that it's the type of files I am backing up even though this new unit replaced an older DDS 3 that backup up the same drives (17 Gig).
