PC cant recognise 2 dvds at once

[TonyJeffs]

On it's own, the Samsung dvd player works fine
When I fit the Liteon DVD recorder, that works, but the Samsung
disappears from view.
Not recognised by W98, Dos or Bios.

Tried changing the jumpers

Any thoughts? solutions?

Thanks

I assume these are IDE drives you are talking about. It's a somewhat common
problem for two IDE drives of different brands on the same IDE cable to have
compatibility problems. Not unheard of, anyway. If they are sharing an IDE
cable, try putting one of the drives on the OTHER IDE channel. -Dave

Tried changing the jumpers

What did you change the jumpers to? One should be Master (MA) and one should
be Slave (SL).
Try putting them both on Cable Select (CS)

Dave,
I'll have to read up on that. I didn't know there would be another IDE
channel, so I'll have a closer look
Currently, 1 ribbon cable connects to my 2 h/d and my two dvd's. KT7a

Scott,
I tried, I think: M:S S:M M:M M:CS
I'll try CS:CS & report back

Thanks

You make it sound like you've got four IDE devices on one cable.
Typically, a mainboard has 2 or 3 IDE connectors, each of which can handle
up to two IDE devices, on an IDE cable with 2 or 3 connectors (3 connectors
if 2 devices). -Dave

I thought that, but closer inspection proves you're right. Amazing how
I got away fitting various bits and pieces without knowing that.

I'm going to leave it till the weekend - just no time to spend an
evening playing with the innards of the pc till then.

Cheers

I tried
CS:CS for both dvd drives.

Only the Liteon was recognised by the bios. Not the samsung
And neither showed up in windows.

Maybe they're truly incompatable.

It's maybe a long shot but you could try putting one drive on the same cable
as the hard drive?

Or if you have two hard drives, you could put a hard drive and optical drive
on each ide cable?

Just a thought. Never tried this myself but then I've never had the same
kind of problem that you appear to be having. Would a firmware update help
or have you already tried this?

Look at the jumper settings very closely. I've had drives that the manual
showed different positions than the marking on the drive and markings on the
drive that were one off from correct. But then I have the worst luck. Might
be a good idea to check mfg websites too.

If the BIOS can't see the drive theirs no way the O/S can.

I think I've been through all the settings. (except no jumper at all)

Scott, sounds a good plan to put each dvd with a h/d but I aint gonna
try it just yet in case I mess up my hard drive access
Will do eventually, though. Recently, Partition Magic, and similar
software, cant see one of my hard disks, although windows works fine.
No idea why.
But it sounds like it'll take a weeks work to sort out. It'll be a
good time to get a new motherboard and faster processor. total rebuild
looming.

Cheers,
I understand it all better...

I have an older 30gb Maxtor HDD that has a simuilar problem. It works
fine on an IDE cable by itself but as soon as I add another HDD it
mostly shows up but on occasion it won't show up in the bios or device
manager. I can fix it by shutting down and doing a cold boot but it
ain't worth the hassle. I put it down to bad hardware and don't use
that HDD anymore.

I guess it makes sense, when the option is there, to get drives of the
same make & similar vintage!
