If I'm not mistaken the Seagate Tapestore installation guide agrees with the way you've got the IDE components configured, but I don't know why. Their instructions say NOT to install the tapedrive on an IDE channel with a harddrive. Maybe someone else can enlighten us as to why. Dave

>>What if there was an Ide tape machine in the mix? Dunno. Having said that, I'll answer anyhow <g>. First, I have not experienced any degradation of a modern primary HD on a channel with a CD except when the CD was actually in use. There may be some reason why the tape would interfere with the HD when not in use; if so I don't know what it is. However, I can well believe you would have SERIOUS HD degradation when the tape is actually in use. These are generally slow devices (tapes), which I would expect will monopolize the single-threaded IDE controller. I'm reasoning by inference; there may in fact be some reason why a tape would interfere with an IDE HD while not in use, but in that case I would expect it to interfere with a CD when not in use too, so I doubt it on this basis as well. Whether HD degradation is unacceptable while the tape is in use depends on when it's in use, I guess. My (very old) experience was that the system is unusable while writing a tape anyhow. These are my best guesses. Anybody know for sure? Personally I would be highly inclined to put the HDs as the two masters and do some informal benchmarking (large disk-to-disk copies) with and without the IDE devices on the slaves. That will give real info rather than erudite-sounding guesswork <g>. (Or maybe it's stupid-sounding guesswork <GG>.) Spots
