With more googling for "HDIO_SET_DMA failed: Operation not permitted" (which is what I got from "hdparm -d1 /dev/hda") I found that my AMD chipset support was in an unloaded module. Loading the module fixed this (and I set this to be built-in for the next round of kernel compiling). I also found a "Tuning Debian" document and ran "hdparm -d1 -m16 -u1 -c3" from it, which seems to have doubled the speed of buffered disk reads. > Note the star (*) signaling the use of udma6 (this is ata133). ata100 is > udma5, ata66 is udma4, ata33 is udma2. Thanks, now my system reports udma5 (ata100), I suppose this is what I should expect from this disk and motherboard (Gigabyte GA-7N400-L1) Cheers, --Amos ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
