What version of hdparm are you using?  What version of Debian?
What make and model is the drive?  What mobo/chipset do you have?

hdparm 4.5-1.2
Debian 3.0r1
Fujitsu MHT2060AT
Kernel 2.4.22 compiled from official Debian sources

Anyone know how to find out my chipset from Dell? They don't seem to be very forthcoming...


not surprising...

when your system boots... watch very carefully, all the boot up messages
that is flyig by ...

	- you will see the ide chipset it found ...
	- you will see the partition tables
- you will see the ethernet drivers
once you know what part number ( chipset ) it uses for the ide controller,
go and find the nearest looking similar kernel driver for that chipset

	insmod  /lib/modules/`uname -r`/drivers/block/that-ide-chipset.o
		( if it complains about kernel version numbers, you will
( need to make your own kernel
	hdparm -d 1 /dev/hda


Maybe you can make sense of these boot messages? I don't see any chipset identifiers, but I do some some DMA stuff. They're attached. Thanks a lot.
