DAT/DDS are inherently unreliable, apparently due to the narrow tape
width. (8mm helical scan tape formats such as AIT are fine)

You might want to price up a LTO or DLT drive - LTO has a number of
features aimed at ensuring what's recorded on the tape is
checked/error-corrected at same time it's recorded.
