R.S> :
30 years ago we were having a rash of them. IBM CE (NOT STK) said it
was a hardware issue. I wrote a program to compare the block count
read and to compare it to the EOV (EOF). In every instance we found
it was the tape drive. We chucked STC (Now STK) drives as it was
causing 2-3 problems a night. STC (now STK). The IBM tapedrives never
had a 237 issue (mod 8s 6250, IIRC). The only bad thing I can say
about IBM tape drives is that it was pure hell loading mini tapes.

I observed an abend S237-04, when reading dataset from tape (using
IEBGENER).
The manual says it is due to discrepancy between # of blocks read
and the value written to EOF label.
The manual also suggests it can be hardware error.
Well... The drive looks OK - only one tape is affected, the media
looks OK (i.e. can be read using BLP).
Q: What component to suspect ?
drive ?
system ?
application ?
Any clue ?
