Hi,
Irecently added a Sony DVD-RW to my hardware to suppliment a Toshiba DVD-R
and a Sony CD-RW. After doing so, Device Manager no longer contains a
heading for CD drives and has moved all three of these devices to "Unknown"
category.

They all seem to working fine and "IDE Drives" category has DMA assigned to
the all.

Can anyone explain why Device Manager no longer identifies these devices?

Thanks in advance,

Try uninstalling then from DM, rebooot and see if they get enumerated
correctly.
Also check see if they are listed in BIOS setup.

Thanks for getting back to me, sorry I 'm slow getting back to you...

Roberto - nope, uninstalling/reinstalling did not work - it was my first
reaction, too.

Nutcase - Your suggested download did not work, either, which is too bad,
because it's pretty insane that such a tweak actually exists.

Nor did a combination of the two....hmmm.

In Device Manager under IDE/ATA...Controllers, all three of the drives are
shown to be working properly and have been assigned 'ultra DMA' modes
(2,4...) but are not identified - the window looks like this under Advanced
Settings:

Device Type - Auto Detect (grayed out)
Tranfer Mode: DMA if available
Current transfer mode: Ultra DMA mode 2 (or 4 or whatever...)

Any other ideas? Could I effect change if I could access the Device Type slot?
Thanks again
Terry Davidson

Hi Terry,

What does the BIOS read the drives as?
Did you recheck that jumpers are set correctly? Made that mistake myself a
few times....

Hi Rick,

Thanks for the reply and the questions. Here's what I got....

This is what the BIOS reads:
Primary Master - my harddrive's model #
Primary Slave - Sony CDRW xxxxx (jumper set to Slave)
Secondary Master - Sony DVD/CD RW xxxxx (jumper set to Master)
Secondary Slave - Toshiba DVD ROM xxxxx (jumper set to Slave)

As far as the ribbons go - the connects at the ends are connected to the
Masters, the connects at the mid points are connected to the Slaves.

Some devices are finicky about placement. You might try placing the new Sony
drive as a master.

Rick -

Thanks and thanks...
Changing the jumper to Master only made the primary slave invisible in BIOS
- switched it back.
This is getting complicated...

Hi Terry,

I would next then detach all of them, then attach only one at a time. If
each is recognized ok separately to ensure that one drive in particular is
not the cause (and if it were, it would likely be the new drive), then work
with two at a time (you already know the two older drives work ok together,
so use combinations of one of them and the new one). It may be that there is
a conflict with the combination, sometimes this is not resolvable.
