t's clear from running the diagnostics (ZTCC, not

forward reads, regardless of the write direction of the data universally
pass).
When you do writes, you have to physically have a read station
positioned after the write station on the head. Are there two such
stations on the drive for reading? Otherwise the writes may just be
blind writes, which would of course work as there isn't much to check
other than to backspace and do a re-read.
Just curious, as though I've got access to TU-56's have not looked for
that detail.
