<snip> I'm curious how you might be expecting to factor in IDRC compression with the data stored on the tape? I believe that the BLKCNT represents what is being stored, not what got sent down the channel. </snip>
I've been reviewing our tape usage with FATS and the TMC BLKCNT is the number of uncompressed blocks on the tape, the IDRC number of blocks is lower of course. I know you've had numerous replies about arithmetic and geometry but I'd also suggest that you lokk for bad block sizes on tapes, users and installations seem less careful with tape block sizes. And as has been mentioned watch out or exclude 'system' tapes, eg DSS, HSM, etc. Jack Kelly 202-502-2390 (Office) ---------------------------------------------------------------------- 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
