They say: >- Maxtor ATA/66 Disk Compatibility - > An ATA/66 disk compatibility issue has been identified and published > by Maxtor, which has provided a utility to correct it.

It is necessary to force the drive to DMA/33 or > DMA/66 mode if using the DMA/66 channels. Maxtor technical note 21006 (at http://www.maxtor.com/products/diamondmax/techsupport/technicalprocedures/21006.html) seems to refer to this. There's a tool called UDMAUPDT that (presumably) pokes the flash on the HDD to say what flavour of UDMA to claim support for. I guess that you're meant to try all the values until you find one that works. I've just all the DMA modes on my drive, the tool seems to work (the corresponding DMA mode is reported in the boot messages), but it still fails in the same way - as soon as you try to do anything to the drive with DMA enabled it goes into a big sulk. My mobo is an ASUS A7A266, with the latest BIOS (v1011). I've rejigged my server now - I've put the two drives that work with DMA enabled on to ide0, and the Maxtor and CDROM onto ide1. I'm booting 2.4.19-ac4 with ide=nodma (so that the thing will start) and then manually enabling DMA on hda and hdb with hdparm. Manually enabling DMA on the Maxtor still makes the IDE channel freeze (as does booting without ide=nodma), but it doesn't kill the machine outright now, so it's a bit easier to play with things. I really do want to get DMA working on this drive (without DMA the performance is ~3.5MB/s as opposed to 40MB/s on the drives with DMA working). If anyone can suggest other things to prod I'd be extremely grateful...
