Anytime. In reality you only have Seagate as your only alternative and
really could not go wrong with either one. That HP unit you have most
likely
has a Seagate inside.
Oh, I made a typo on the model, which should read Sony SDT-D11000

Or a tape getting a bit finicky? Borrow another drive and try the tape in
it.

I don't doubt you in the least, but this is pretty much what I hear when
someone comes in asking for help or a new tape drive. They don't usually
get to this point until they do a full blown disaster recovery. If you
really want to be 110% sure you could do a full disaster recovery by
temporarily replacing your HD in your computer and give it a whirl. You
might be amazed of your results

Personally, I would open the unit up and make an attempt to salvage the DDS3
since your requirements don't require speed. The head on that unit is
really rugged and I doubt it is worn out even if you got the unit second
hand. Of course you could have other issues with the drive, but that is the
easiest and cheapest area to check first.
As for getting into the unit, you can try a couple of things. I'm assuming
its an external SCSI case? If this is the case, you will need to slide the
main frame out from the back of the case. Lightly prying the plastic up in
the rear and looking for the four plastic catches usually do this. Some
models may have at least one setscrew under the rubber feet.
Once this is done you will have the unit exposed and ready to remove the
whole assembly from the external case frame.
Next remove the four screws holding the two side rails from the tape unit.
(This is the point were the tape unit can be installed in a standard 5.25"
bay) faceplate color optional and easily found online.
After removing the side rails you will need a small Phillips to remove the
screws holding the top cover to expose the head and other mechanism.
Clean and inspect prior to assembling in reverse order. Good luck.
