My guess is that your bad performance is explained by lack of DMA. You could verify that guess by studying the output of hdparm -i /dev/hda You will probably get better performance with DMA if you instead use your SATA drive in SATA mode. That could probably be accomplished by changing some setting in your CMOS setup. My guess is that you now have a setting which might be named something like "legacy" or "IDE" when you instead shoule have a setting named something like "SATA" or "AHCI". Once that setting is changed your kernel might instead see your drive as /dev/sda instead of /dev/hda. As such you might have to reconfigure your /etc/fstab and/or your bootloader. regards Henrik -- The address in the header is only to prevent spam.
