Hi Scott, seeing as that your experience is different than 1% failure rate reported most posters, I am interested in an estimate of what kinds of error rates you saw. Were you seeing the 15-50% referenced in the article? Or rather just something in excess of the 1% being reported? I definitely saw many media errors, but in the scheme of the tens of thousands of tapes being passed, it was certainly below 1%. Of course that didn't help much when you took a tape error in the middle of a hundred reel file, and had to explain to the programmer once again the importance of making their two day jobs restartable. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
