What model of 3420 drive do you have? I am pretty sure at least the later models (4, 6, and 8) could only read 1600 or 6250 bpi.

One of our user areas sent us 9 3420 tapes today, and some of them appear to be 800 BPI. When I run tape map against the tape I get the data in the attachment. I am trying to read these files on a 3420 tape drive, and when I put the density (DEN=2) into my JCL I get a 413-24 abend. I've tried various combinations and I cannot seem to get these old tapes to read, and without density IEBGENER gets a RC=12 for conflicting DCB info. I've also tried BLP and specifying the DCB parms directly, and still no luck. Does anyone have any suggestions as to how I can possibly get this to read on our tape drives, or is there a hardware setting on a 3420 that will make this possible? I looked in the archives and did not find anything specific about this, and this is a little before my time.
