I wrote a lot of DDS2 and DDS3 tapes back in the day. When my DDS3 drive broke, I got another drive. I found out that my first drive was seriously out of calibration, and though it could read its own tapes, other drives could not. All the data was gone.
I'm considering getting an LTO drive, but I won't do it unless either I buy two drives, or find someone else with the same generation LTO drive who would like to exchange encrypted backup tapes for verification.
