I had a series of HP 35480As (DDS-1) which each lasted about 6 months. Things have changed. I have had no trouble with more recent DDS-2 drives, including the Archive changer I'm currently using. I've heard of problems with refurbished drives, though. > Media life is short, too. I've had no trouble at all with this. I have retired some tapes which I've been using twice-weekly (16 hours tape motion per week) after about 18 months. I don't think that's unreasonable, especially when you consider that a 90m DDS tape costs about $1.50 per gigabyte, compared to about $45 per gigabyte for a QIC-525. Greg
