To anybody reading this thread looking for an answer. Here's How I did it.. Connect dvr drive to sata 0. boot with gparted .19.1-4 delete all current partitions. create new ntfs partition. open terminal and type these commands. "sudo su" press enter then "hdparm -s0 /dev/sda" it tells you PUIS is now off. shut down. Maybe this will save somebody time over the previous instructions of searching for "hdparm -s0" and reading thru a 39 page thread.
