We > >3M makes them. They are DC600HC tapes. I used to purchase the 3M DC600HC tapes for use on a HP9144 on an HP1000 and while they are pre-formatted, they are not certified. For a 150 ft tape it required about 15 minutes to certify and an hour for 600 ft tapes. During the certification process, the system would be completely locked up and unusable. I'm not sure if HP-UX requires certified tapes or not. And if so, what program would be used to certify them. I believe that `certified' means that a bad block scan is done and spares are created. This is necessary since HP also treats these tapes as blocked media suitable for file systems. We now have 2 cartridge tape drives and a 9-track drive and ONLY use the cartridge drives to build recovery systems. Used 1600 bpi 9-track drives for HP systems are cheap so if you do a lot of tape handling it might be worth it for you. -- Steve Fullerton Statware, Inc. scf%statware.uucp@cs.orst.edu 260 SW Madison Ave, Suite 109 orstcs!statware!scf Corvallis, OR 97333 503/753-5382
