How can I query my DVD and HD drives to see what IDE channel they are on?
I have 3 DVD/CD ROM drives and 1 HD. If I look up the DMA settings in
Windows, they are listed as "Primary IDE Channel, Device 0" and "Primary
IDE Channel, Device 1", "Secondary IDE Channel, Device 1", and
"Secondary IDE Channel, Device 1"
However, I can't tell which drive is connected to which IDE channel. At
least not without opening up the box and looking directly at the
hardware, which I'd rather not do for reasons of accessibility.
I'm trying to copy the DMA settings that I have in Windows to Linux, to
see if I can get the performance to match. Currently the DVD drives are
underperforming in Linux (as in, not working).
So, is there a command line query which will match up the name of the
drives and their names in /dev/ to their IDE channels? I thought of
hdparm, but if it says in its output what IDE channels the drives are
on, I can't tell.
Thanks.
Dave
