Hi, I have a very strange experience. When i try to play the video file in Protools 5.0.1 MIXPlus on G4 with ATTO DualChannel SCSI, it works better if I play it from internal ATA drive. if i try do play it from Seagate Barracuda 18 GB Ultra160 SCSI drive connected to the second ATTO bus, the movie is played with droped (lost) frames and get drops. It looks crazy! Anybody knows what's going on? Should I format by ATTo Express ProTools my SCSI drives for only HFS (I just have the HFS+ format on the SCSI drives)?!
