The master/slave setting is set to exactly the same setting (slave) as the CD-ROM drive it replaced (there is another drive on that same cable). And how do I change the DMA settings? I think this is what may be causing the problem. Linux currently doesn't recognize the drive, as it is disconnected. But I believe it's /dev/hdb (although it might be /dev/hdd). There are two hard disks at /dev/hda and /dev/ hdc that are mirrored together and mounted as /home. Alfred
