i have recently acquired a tape backup system for my 3b1 and have two questions: 1) the system came with release 1.0 of the software. are there any known problems with that software and/or are there any updates? 2) the manual suggests 3m dc 600a tapes or equivalent. have any tapes caused consistent problems in this use? is there any classification of good or bad tapes? -- arthur wouk internet: wouk@cs.colorado.edu

I'd like to know of any updates to this software (if there were any ;-)) With the 1.0 UA scripts as they are (and I didn't look at them... I just use `gtar') the "multiple, 3B1 type, sets" script seems broken... the "display tape contents" always shows first set as "Broken" (or something like that), and all the other "slots" as "FULL" after only one "backup folders" operation. `Gtar', on the other hand, has no problems appending files to an existing archive (I haven't try `tapecpio', so anything could be the culprit... `tgetoffsets', `tgetovwrit'... hmm). Anyways, the "user mode" software that came with the box doesn't exactly shine, but the box does work, and, in its own ways ;-), serves it's pur- pose OK. >2) the manual suggests 3m dc 600a tapes or equivalent. have any tapes >caused consistent problems in this use? is there any classification >of good or bad tapes? An old 3M tape I got with the unit was wery clonk'y, but it had no errors, and so neither do the Sony QD-600A, but they are much quieter (smoother(?)).

The FixDisk allegedly corrected some problem with the original Floppy Tape Software, but didn't fix the date&time restoration problem. I don't know how you feel about it, but I prefer for the original dates and times to be restored from tape. The fix was simple: alter the scripts' tapecpio lines to include an "m" >2) the manual suggests 3m dc 600a tapes or equivalent. have any tapes >caused consistent problems in this use? is there any classification >of good or bad tapes? Deja vi? (Pun intended) Thought I just posted something about tapes. In any event, the 3M DC600A are the preferred tapes and actually give you 620' vs. the 600' with the Sony QD-600A tapes which also work fine in the drive. Comparing the 550 oersted and 12,500 tpi ratings, it would appear the 3M DC6150A tapes would also work, but these (generally) are more costly and were designed for use with 150MB drives (still with 600' of tape).

Well, in my playing, I have have used many different tapes. The ones that work the best (as I have found) are the Verbatim DL600, the Maxell MC6000, and the 3M DC600HC. The last one is somehow "preformatted-do not degauss". It still needs formatting, though :-( Believe it or not, the only tape I *have* had problems with is the standard 3M DC600A tape.

How's that for bizarre?!? My only problem to date was with a Dysan 600A type tape. The tape actually snapped!! I have several others which have held up fine. I also have 3M's, and some Sony's too.
