I just got the iomagic rebadged benq 1655 and put it in an external usb/firewire enclosure. When I do a nero cd-dvd speed quality scan via firewire, I get garbage for “PI errors”. When I test via usb, the quality scan looks normal. By garbage I mean that my PI errors look like random 9 digit numbers, and my pi error total keeps wrapping around, both negative and positive. I get this right away from disks that have no true errors (they read fine via firewire).
This is my first drive with PI/PIF scanning ability; maybe there is there a config trick to get the 1655 to quality scan via firewire? Oh my firewire bridge board is an old oxford 911 one.
