Product literature for SDLT drives (110/220 and 160/320) say that they can read DLT IV tapes written on DLT 4000, 7000 or 8000 drives. (SDLT 300/600 drives don't claim to be backward compatible in this way.) But when I've tried it with such tapes from DLT7000's, my SDLT 160/320 drive won't accept the tape. It just takes a long time "looking at it" and then ejects the cartridge. (no software involved).
I read other postings on the web that it has failed in this way for others too. But the "official" literature from Quantum, HP and others says it should work. Has anybody out there actually read DLT7000 tapes on an SDLT drive? If so, is there some sort of trick/special setting, etc. ?
Thanks for your help.
