Hi list, I'd like to delve into the collective knowledge of those out there, with the following questions: (apologies if the TZ875N isn't quite 15 years old and is as such OT) 1) This changer currently has a 10/20GB (DLT2000) drive in it. Tapes for this (DLT 3) are hard to find on ePay. However, the 15/30GB DLT 3XT tapes are plentiful. What would happen if I tried using those? 2) Can I remove the DLT2000 drive and fit say a DLT4000 and will the changer still work? 2a) ISTR some discussion a while ago about the drives having to be a certain specific type (marked "Changer Only" or somesuch) to be useable in a changer. Is this right, or can I just slap any old DLT4000 I find in there? Sorry this is a bit vague - I haven't taken the thing to bits yet. Looking at its construction, it's going to be quite a challenge to do so. TIA, Ed.
