The problem isn't old software as Cache-A sold its assets to ProMax in September of 2014 and they have not released any new software for the original hardware since that time. The LTO-6 models are all running the final release v3.4.3.

I'm surprised you didn't see any errors - did you ever check the Tape Info in the past? Did it ever indicate that files were really there? I've never seen that dialog report change over time, and we always recommended verifying that report before putting a tape away for archive.

Yes, PRP won't run on the Cache-A and will require a Mac and a SAS card with any LTO drive or a Mac and a Thunderbolt LTO drive like the mLogic. I'm just thinking maybe you could find a third party that has some alternative way to read LTFS tapes to see if something is going on with your Cache-A. You might alternatively try a new archive on the Cache-A with a different tape to see if you can successfully write and recover newly written files.

Sorry that I can't be more helpful in this case.
