Post subject:  SATA DVDRW Now Working!
Hi all,

I have been using myth for a couple of years know and been adding bits to my box as and when nescessary. My box is very much a live project as the plasma I have has no tuner.

My latest upgrade involved a major switch I swapped the case motherboard and cpu.

I upgraded to

A 945 chipset motherboard (with 1 * ide controller) and 4 * SATA.
I930 cpu 3G Dual Core
Thermaltake silent tower (Fanless Heatsink)
Thermaltake mambo case.

I know have a almost silent system. :lol:

As mensioned above the new motherboard only has 1 ide controller.

The data I had was on a IDE hdd 200GB and it was 80% full so i wanted to keep my recordings. I tried to install a sata harddrive on the system before i went live with little success I wanted to use the legasy mode in the bios but even though the bios said the sata was a primary master myth still saw it as /dev/sda. I started to do a manual install but was worried how I would upgrade in the future.

Anyhow I intend to upgrade the hard drive later clone it to a 400g or so I will stick to ide untill myth will do a auto upgrade automaticly, need to be able to get the box back up and running quickly.

I am a little concerned about putting both the data and dvdrw on the same cable so I have got myself a SATA dvdrw the only thing is I cant get it to go.

I have looked in the /etc/fstab but i cant figure out where to set /dev/dvd and /dev/cdrom to = /dev/sda.

Anybody any pointers.

Rgds,

Simon

Post subject:  Almost there. Done
Hi all,

I have almost cracked it,

I deleted

/dev/cdrom
/dev/dvd

then added

ln -s /dev/sr0 /dev/cdrom
ln -s /dev/sr0 /dev/dvd

now xine plays dvds !!

Although when i tried to write a dvd i got a backend crash

can't connect to backend is it running !

I will continue to experiment and let you know how I went on

SATA DVD writers may be the answer to our prayers if you want to continue using ide drives and only have one ide channel.

Ok now fixed it, motherboard was set to compatability mode which messed up the hard drive it would only go in PIO mode. Don't think it could read the data off the hard drive fast enough to write to the dvd!

So Sata DVD Writers go in Myth !!!!!!!!!
