It's a loooooong time before Imation discontinues a tape. Problem is, these Colorado things barely worked to start with. I've got a heap of dead and useless ones.
It has been sitting on a shelf for almost 6 years and still works ok. I can read tapes that I made in 1994 and 1995. Just that two sets of Windows 95 backups seem to be a "Bad Format" or something.
I recall in 1994 that I had to download an updated version of the tape software to avoid CRC (Not you Christian) errors on restores.
