With 1TB external drives now plentiful for what you used to pay for a few tapes most folk have disposed of tapes and moved to DVD/BluRay and external HDDs for backup.
Once in a while you find an old shop that didn't change and they suffer as they can't find repairs or parts.
We used to backup everything to an external DAT drive using 4mm 12-24Gb DDS3 tapes to our G4. The day came when the drive failed. No problem we moved to a DLT Tapes and life went on and on.
Now, of course we need to retrieve something that was only backed-up on DAT Tapes.
If we had PC's it would'n t be a problem since there is plenty of refurbished Drives available on the net.
Not so for Mac compatible drives.
Google search give me results for HP drives that do not work for Macs.
