Copy Thru

CopyThru v3.1 makes duplicates of HFS volumes with the option of segmenting the copy through a fixed (or simply not-removed) volume. In other words, it is a multi-pass block copier for removable media. It is particularly useful for making backups of valuable data stored on Zip, EzFlyer, Jaz, and other carts. CopyThru can also perform high-speed direct disk-to-disk copies. CopyThru fills up one or more hard drives (or as much of it as you permit to be filled-up) with blocks, ejects the source volume, requests the destination volume, and then repeats until the copy is completed. It is heavily multi-threaded and uses asynchronous I/O so is much faster than Finder-dragging. CopyThru can copy almost anything; including disks with scratches, ball-point marks, footprints, and even pin-holes. Many options are supported. Although v3.1 is now shareware it is quite inexpensive. Ben Hellstrom hellstrm@jagunet.com
