Try forcing it to use a slower mode (not that I know how..).) The disk _appears_ to work correctly in PIO4 mode... but 16MB/s isn't anything to scream about. I was using an 80-conductor, 40-pin cable on my bootdisk (ad0, 20GB), but, I switched the cables originally so that the ATA66/100 cable is on the 40GB drive. Everything works beautifully in PIO4, but, that's sort of a hollow victory considering how slow that works... and, what's strange is that even with the plethora of errors I reported-- the read/writes still complete & the data is all there. Is there any way to rule out if it is the disk or the software? My BIOS is set to LBA mode, UDMA is enabled for ata1-master there (if it matters)... Erik. -- E. L.
