well, your udma is on .. but you could do yourself a favour try this as root: hdparm -u1 -c1 /dev/hda this will set unmaskirq, which is usually a good thing, allowing processing of interrupts, while the drive is busy. c1 will set io_support to 32. Both should give you a little bit of speedup. With hdparm -iI /dev/hda you can check which (u)dma mode is used by your drive. -- [email protected] mailing list
