It formats the disk on the fly using its own format. This allows more information to be put on the disk and also gives you the good error recovery. The amount put on the disk depends on the number of files, it seems not to have minimum cluster size. I have gotten an average of 500K on a floppy for some of my backups. It is not copy protected, but does test your system at installation time. It checks for what kind of floppy drives and how many, "tests" your DMA chip and your CPU. I have heard and seen test failure reports on early PC's due to a bug in the 8088 CPU. I have also heard that sometimes the installer reports a bad DMA when it is actually the CPU. Using DS/DD disks it works fine, I have tried using some SS/DD disks that have worked with no bad spots formatted by DOS and they usually fail under FastBack. It is quite picky about disks. If you are in the middle of a backup and it gets a disk error, it will abort and you will have to start the backup over. A pain if you are on disk 88! It retails for $179, but have seen it in several mail order listings for under $100. -- Timothy Lange PC Learning Resource Center Purdue University Computing Center West Lafayette, IN 47907 317-494-1787 tim@j.cc.purdue.edu
