I'd direct my continued research into "geometry" of disk drives. There is (or used to be) a geometry option in the labeling/partitioning part of sysinstall. Never used it myself. But remembered that it wanted to know out how DOS/Windows was doing things so it could do the same. And the option was there only to override the auto guess. > DMA isn't that critical right this minute but `Bad things happen' if you > switch from CHS to LBA after installing partitions. > > > I'm copying this from an envelope I wrote the dmesg text output on.

By any chance did you transpose the 1 at the end of 89331 on to the end of 63? ad4: 43967MB <Maxtor 54610H6> [89331/16/63] at ata2-master UDMA100 Heck, I don't really know if I have LBA on or not. But I've seen over 23MB/sec on the drive using bonnie. This drive has never been seen by a Windows OS since I opened its anti-static bag. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
