ddpt

Copy files (like dd) especially SCSI/storage devices

ddpt is yet another variant of the Unix dd command used to copy files. This variant is specialized for moving data to, from or between storage devices. If requested, SCSI commands can be sent to read or write data. SCSI commands are sent via a pass-through interface. Also supports two variants of SCSI copy offload: xcopy(LID1) and the disk->disk subset of xcopy(LID4) known as ODX.
