Has anyone been successful in running an ESDI drive at 1:1 under SCO Xenix 386AT 2.3.1? I'm running on an AST/386 with an Adaptec-2320 (a 2322 without the floppy) with a Micropolis 150MB drive, 36 sectors, etc. When I do a raw read from a partition (i.e. using 'dd' on a raw device with a big buffer), the system doesn't keep up with the 1:1. Should I switch to 3:1 interleave? How 'bout switching to a WD1007 with a track buffer? (I thought SCO had a bug which flushed the buffer for every read...) I really am peeved that I spent lots of extra $$ for ESDI and am only getting st-506 performance. Please e-mail replies to erik@mpx1.UUCP, unless mpx2 happens to be in your 'paths'... Thanks!
