Aren't tape labels written at the "least common denominator" that a drive
is capable of writing? If the density of a written tape is only checked by
looking at the labels, that would explain what you are seeing.

From z/VM 5.1 HELP (and the manual), George seems to have it right.

UofKs TAPEMAP command is great, but badly out of date. Rich's TAPINFO
modules may fall into the same bucket?
Do you have a z/OS system around running FATS or FATAR? Those, being
current and supported products, are likely to produce reliable results.
Once you find out, you can develop and distribute updates to TAPEMAP and
TAPINFO, right? ;-)
What does TAPE QUERY show before and after "TAPE MODESET (XF"?

Subject: Tape Modeset for 3480 XF
Maybe I'm missing something obvious, but I'm trying to write to a 3480
cart using TAPE MODESET (XF. The TAPE QUERY command confirms that the
drive is capable of writing mode XF. But whatever I do, the data is
apparently being written as 38k bpi, according to both the UofK TAPEMAP
and Rich Greenberg's TAPINFO Modules.
I've tried issuing TAPE MODESET (XF, writing a VOL1 hdr with the (XF
option, issuing a MODESET then doing a TAPE DUMP (XF w/o a label, but
in each case the utils report that my density is 38k, not XF.
The carts I'm using are Imation Royal Guard 210MB. Are these not
capable of the higher density? I thought this was a function of the
drives, not the media.
What am I missing here?
