Hi,
This is part of dmesg : ... Journalled Block Device driver loaded Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx hda: QUANTUM FIREBALLP LM30, ATA DISK drive hdb: WDC WD400BB-00DEA0, ATA DISK drive hdc: GoldStar CD-RW CED-8083B, ATAPI CD/DVD-ROM drive hdd: CREATIVECD3621E, ATAPI CD/DVD-ROM drive anticipatory scheduling elevator ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: max request size: 128KiB hda: host protected area => 1 hda: 58633344 sectors (30020 MB) w/1900KiB Cache, CHS=58168/16/63 hda: hda1 hda2 hda3 hda4 hdb: max request size: 128KiB hdb: host protected area => 1 hdb: 78165360 sectors (40021 MB) w/2048KiB Cache, CHS=77545/16/63 hdb: hdb1 ...
When I try to set dma on on either of the disks, I get the following: [root@debian-f5ibh] ~ # hdparm -d1 /dev/hda
/dev/hda: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off)
