I have a motherboard with an integrated PDC20267, so it has four IDE channels, and I was using it with a secondary disk. Channel (mobo's) 1 for one IDE disk, channel 2 for optical drives, and (pdc's) 3 for the other disk. I discovered that it read at full speed but wrote at slow speed (or the inverse, it is not the big issue). The worst was that things I put in that disk had errors, detected it while verifying a CD. Being busy with other issues, I just put both disks in channel 1 and disabled the Promise chip. The kernel was 2.4.26, when I have time I could a try with newer ones (but not soon, cos swapping capables in that machine also means touching the SCSI disks). I did a quick search (PDC20267 data error) today and got: http://www.ussg.iu.edu/hypermail/linux/kernel/0410.3/2551.html https://www.redhat.com/archives/ataraid-list/2001-July/msg00021.html GSR -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
