    LTO 4 5 6

    Are they 'backwards' compatible so to speak? Can an LTO 6 drive read and write to an LTO 4 tape? Or is it a case of 'read only' for older tapes?

    Thanks

    I believe LTO are read/write compatible with the prior generation, and only read compatible with the generation before that. So an LTO 6 drive can read/write LTO 5, and read LTO 4.

    All LTO drives will read and write to the previous generation of tapes, and will read from two generations back.

    However, if you put a later generation LTO tape into any LTO drive it will spit the tape out.

    The only exception is the cleaning tape, which seems to be compatible with all models.

    The others have it. We still use LTO4 tapes in our LTO5 autoloader most days of the week, as we've not yet grown to need LTO5. Soon, though.
