DMA-33—robbing you of 50–150% of your potential performance. Once
Linux is installed, you are free and encouraged to start tweaking the configu-

to data loss.
It is best to test HDPARM settings on a fresh installation of
the operating system before committing any applications or
programs to the drive and prepare to back down on the set-

HDPARM tests show erratic results or fail.
