If using the same version of sw to write on old dlt and read on the new sdlt solve your problem, this mean that the two versions of Brightstore are not 100% compatible.
You cannot blame your hardware for that

The best chance at restoring data from any given tape is by placing it in the same drive it was originally written on.
Some DLT tapes will read in an SDLT drive but many won't and it depends on the various alignments (or misalignments!) of the respective tape mechanisms, tape head density's, track positions etc etc.
(Sort of like reading 360k floppies in a 1.2Mb FDD!)
If you can read the tape in question fine in the older drive unit then the tape has obviously not gone bad and it isn't a backup software problem, but is purely a drive tolerance issue.
You need to keep your old drive so can access all the existing tapes when required.

My guess is that they've "optimised" something while writing the later driver, without thinking about backward compatability. If you've got any legal requirements which require you to keep your data for a few years, this could really screw you up.

But in any case, thank you all for the responses to my question.
