From my experience A foolish remark. The change and added "nothing" as you called it was the TK50 media was formatted (init'ed) and verified at the higher bit density. It was also marked differently so these with TK70 and TK50s in their sites would know them apart (and DEC would in their stockrooms too). TK 50 had been around for a few years before TK70 and was not enjoying a good rep as the early tk50 drives where to say the least unreliable. They are fixed and the TK70 was really the DLT standard setter for reliability in field use. Marketing really didn't want the two confused. The TKs be came part of Quantum in the big sell off and quantum really wanted divorce them selves from the TK50 or any TKmumble plus moving the performance ahead. So there is a lot of "nothing" between the lines. Allison
