No sarcasm, whatsoever, was intended. For long-term storage, I wouldn't trust 4mm tapes, or any other very high-density media like that. >you're advocating putting >6G of data on 6250 BPI magtapes? Well, backing up 2GB on such tapes isn't too bad. It all depends upon how valuable the data is, and how long you plan to store it. To take this a step further, for small amounts of data, such as backing up EPROMs, etc. in older computer systems, for preservation purposes, I'd recommend using punched mylar tape. As an aside, those 4mm drives certainly deprive computer operators of fun jobs - nothing like getting paid to sit around and wait for each magtape to fill up (having to work 3 minutes out of each hour, and hacking for fun during the other 57 minutes, isn't a bad deal!). >Personally, I've never had a 4mm fail. (DEC tlz04) It's still relatively new. Give it time to fail. :-) :-) :-) -- R. D.
