With 3.04d this is not possible (without hacking), I believe.
4.x (won't even compile on 2.2.x kernels due to kernel API
changes) removed compression to handle hard write errors
more gracfully.
You might wish to format your tape (or format/update the bad
sector map only), but that can take many hours (8-12 for your
1.65 GB tape).

Try reading your tape and see how many ECC corrected errors
turn up ... You'll get a few for every 100 MB.

Format the tape under Linux. Or hack/code the tools to add
that data. :-)
