Came with 200MB of shareware in a folder. I moved it to my G4 HD to clear the room off the drive. So many utilities, etc., a very nice touch. Straight copies from drive to internal HDs keep activity light illuminated almost contiunously. This seems to be a good indication of how hard the drive is working.
Audio file playing only causes the drive to blink every second.
Drive does not interfere with either the Canon camera or the Sony deck capture or playback. OWC recomends not plugging the drive into a hub but directly into a port on the computer. I did this. There are two ports on the back of the drive. I haven't tried connecting another device to the drive, though.
