your DDS-4 tape for some of my DDS-2 ones, I'd be quite happy!
I'll elaborate a bit. Essentially a tape drive can read/write lower
capacity tapes, but not higher capacity ones. A DDS-4 tape drive can
and read and write DDS-4, DDS-3 and DDS-2 tapes. A DDS-3 can read and
write DDS-2 and DDS-3 tapes. A DDS-2 tape drive can read and write
Note I've not mentioned DDS-1 tapes above. I don't think the latest
DDS-4 tape drives can write to the very old DDS-1 tapes and possibly
not even read from them. I assume DDS-2 drives would have no such
problem. I'm not entirely sure on the DDS-1 status, as its so old I've
never even bothered considering it.
It is recommended that you only use the tapes of the drives capacity.
i.e. while a DDS-4 drive will read/write DDS-3 and DDS-2 tapes, its
not recommended you do this on a regular basis.
There's a doent discussing this in more detail on HP's web site,
and probably Seagate's too.
