Hey Tim, I'm in the same boat, except kernel-2.6.3-1. hdparm returns this error: [EMAIL PROTECTED]:/home/mike# hdparm -d1 /dev/hdb /dev/hdb: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) [EMAIL PROTECTED]:/home/mike# I am stuck, I hope somebody has the answer...
