Jam version 2.1 and 2.5 only supported SCSI CD Recorders. With the release of JAM 2.6, Roxio added support for USB and FireWire (1394) CD Recorders. To determine whether or not your drive is supported check Roxio's list of recognized mechanisms, if you do not see your drive listed and it is a USB or FireWire CD Recorder check with the drive manufacturer on what the internal drive mechanism model is and compare that to the list of recognized drives.
