LTO-3 Hardware compression

I was told today that the LTO-3 (IBM) tape dirve in my SL t50 library does not support hardware compression. I find this a little hard to belive as the drive was averaging about 1.2:1 ration before being swapped out for a replacement library. Now I get no compression. The Policys in BE 11d were not altered only the hardware was swapped out. The policies are set to hardware unless unavailable then software. What gives?

As far as I know all LTO drives support compression, including LTO1, LTO2, LTO3, LTO4 made by IBM, HP, and Quantum/Certance.

It very well may not support compression but to me that just means it is defective and must be replaced.

I'd start by going back to them about it and if they maintain it does not then have them provide documentation to that effect and then check that against the original specs, and documentation for the library.
