Well... audio tapes don't work as a substitute for a D/CAS cassette. At least not with my TEAC drive. First attempt, drive takes the tape, but starts blinking the access light as soon as the drive is locked, never tries to do anything with it, software says "No Media". After a quick 2nd look at the transport, I see a small finger sensor looking for that notch. 30 seconds later with my pocket knife, my audio tape has the notch. 2nd attempt, drive sees the tape, software reports "Busy" as the drive spins the tape to the end, clacks to the end and tries to spin some more, then gives up, rewinds a bit and stops. Software reports "Hardware Error". My guess is, it is looking for some kind of end of tape marker. I tried both clear leader and leaderless tape, neither worked. I also tried a higher grade tape (Type II, 630 oersteds or whatever that word is). I don't know if the end of tape is a specific magnetic marker like a format, or what. Winding the tape to the end in a tape deck and putting back in the drive causes it to rewind the whole tape until it clacks at the end again. So it is definitly trying to rewind to the start of the tape and is simply never seeing that it is at the end. It is possible that the drive is broken, but since it is seen by Retrospect on the Mac, and gives status updates as it goes, and the transport does its thing... I tend to think the drive is fine and I just can't use an audio tape. So... does anyone know a supplier of these tapes? I haven't been able to turn up anyone that actually sells them anymore. A few people on this list offered to try to locate a spare tape for me for testing... but I'm not going to ask anyone to go thru that effort if I can't get a regular supply of tapes anyway. The drive is a TEAC MT-2ST/N50. The following appear to be compatible tapes: MaynStream 20; Teac CT500 D/CAS; Verbatim ST500; Teac CT-600H; Verbatim ST600; Maxell CS-600HD; MaynStream 60; Teac CT-600N; Maxell CS-600XD; Verbatim ST600XD; MaynStream 150. All in all, it probably isn't worth much more effort. Its only a 150 MB drive anyway. So for normal use, there isn't much I can do with it (at least not when I deal with the cost ratio of Zip disks or CD-R's). -chris <http://www.mythtech.net>
