Emulex QT14 and Fujitsu M2442: Problems writing two or more files on one tape

Hi there, I recently acquired a DEC TSV05 QBUS Pertec controller and a Fujitsu 9-Track tape drive. My TSV05 actually is a relabeled Emulex QT14 with a different prom on it - The DEC version only talks TSV05 emulation whereas the QT14 also speaks TMSCP. I've put the controller into my VAX 4000/500A which runs VMS 7.2 The Drive/Controller combo works fine for reading tapes. Writing works as well, but only the first file can be written. Upon trying to write the second file, the drive starts to spin the tape back and forth and then stops, giving the following error message: %COPY-E-WRITEERR, error writing MSA0:[]VMS072.B;1 -RMS-F-WBE, error on write behind -SYSTEM-F-DRVERR, fatal drive error %COPY-W-NOTCMPLT, DUA4:[000,000]VMS072.B;1 not completely copied To me this looks as if the drive has problems writing file marks, or I am doing something wrong. As I do not have any documentation on the drive, I'm asking here: Does anyone know the problem and has a solution for it? Do I need to configure the drive or the controller differently? Are there any VMS paramters I need to modify to get the thing to write multiple files on one tape? Thanks in advance, Hans -- finger hans(a)huebner.org for details
