I just add a 160GB ATA133 drive to my system. On this system I have an IDE DVD burner on IDE channel 1. The 160GB drive is on IDE channel 2. When ever I try to copy any data from the DVD drive to the 160GB hard drive the system locks up. All I can do is a hard reboot. I have the follow sysctl in my loader.conf hw.ata.ata_dma=1 hw.ata.atapi_dma=1 hw.ata.wc=1 I've tried to set hw.ata.wc=0 an hw.ata.ata_dma=0, but still the machine locks. The machine is an older dual PIII and the IDE busses max rate is UDMA33. All the other drives on the system are SCSI U160 and I have no problem copying to the drives from the DVD drive. Anyone have suggestions or a way around this other than only using the SCSI drvie to copy from the DVD?? Otherwise, It look as though I'll need a new machine for the ata133 drive because all my PCI slots are filled!!
