Prob: IDE Drives recognised as SCSI

Greetings!

Running an ASUS P5LD2-VM

Two IDE drives - an IBM and a Samsung installed on the red PRI_EIDE
connector are not recognized by the IDE Detector in the BIOS.

In XP Device Manager they appear as SCSI drives and do not show up in
Explorer.

They are inaccessible to me.

Why is this happening?

How can I get them to be recognized as the IDE drives they are by the
IDE Detection system so I may use them?

I have a non bootable IDE as Primary Master, my DVD drive as Primary
Slave connected to the blue PRI__IDE socket, and a S-ATA as Third
Primary Master - bootable XP

Thanks in advance for any assistance!!

There's a driver for that on the CD that comes with the motherboard.
Did you install that ?

There's an enable/disable in the bios for that connector.
 
When you add an ATA/EIDE (or SCSI) controller into a Windows computer,
It will show up as a SCSI device in Device Manager.

You list a Red PRI_IDE and a Blue PRI_IDE
Motherboards (usually) come one Primary IDE and one Secondary IDE
controller.
How come you list 2 primary controllers?

Do the ATA/IDE devices show up in Disk management?
(Right click on "My Computer", click on "Manage", then select "Disk
management"

That's the way Asus has chosen to do it. That appears to be
because they are on different controllers on the motherboard.
 
You have connected them the wrong around. The blue connector (controlled by
ICH6, as are the SATA connectors) is to use for bootable media, as the red
connector (controlled by an ITE8211F) is an add-on controller and as such
seen as SCSI in Win..

OK - one is blue and is described as the Primary IDE connector (40-1
pin PRI_IDE), and the other is Red and is described as ITE IDE
connector (40-1 pin PRI EIDE)

The two drives on the blue (Primary IDE connector show up in Device
manager as SCSI devices but are inaccessible.

Thomas:

On this connector, described in my manual as the Primary IDE connector
(40 -- 1 pin PRI_IDE) I have an IDE drive (non-bootable, used for
backup) set as primary, and my DVD drive set as slave.

My bootable disk is a S-ATA disk on a S-ATA connector.
connector (controlled by an ITE8211F) is an add-on controller and as such

On this connector I simply wanted to install two more IDE drives for
data storage


OK - so am I not able to install ordinary IDE drives on this
connector?

If I am able to do that, could you kindly explain how to have them
installed as IDE drives so that I may access them? :)

In the manual it descibes this connector as one which "supports two
IDE hard disk drives for easier data storage".

Two IDE drives - an IBM and a Samsung installed on the red PRI_EIDE
Yes - I have installed that driver - many times :)

Yep - enabled.
Click to expand...

Check it again. Did you enable ITE8211F Controller?
Try Standard Mode.
That is for PCI_EIDE (red) connector.
 
Check it again. Did you enable ITE8211F Controller?
Peter:

Yep - checked several times;)


Standard mode what/where?

BIOS?

Did you get my hint about motherboard manual?
If you have misplaced it, it is here:
http://dlsvr01.asus.com/pub/ASUS/mb/socket775/P5LD2-VM/e2281_p5ld2-vm_v2.pdf

Now, which IDE disk does not show up?
That one on PCI_EIDE connector (red)?
If this one, Standard Mode bios setting is shown on page #2-27 of manual.

Or, the one on PCI_IDE connector (blue)?
If this one, disconnect DVD from ribbon, set drive jumper for master; and
boot to BIOS again.
It should be visible as on page #2-15 from the manual.

Make sure hard drive has power attached and it spins.

Yes I got your hints - I have RTFM'd so many times that some pages are
starting to fall out and the corners are dog eared !

Manuals are not always what they are cracked up to be.

I am at work, and the offending system is at home, so I will take your
excellent advice and pour over it, the manual (again) and my system
tonight when I get home. Thank you very much.

Cheers!

Doc.

IDE/ATA/ATAPI came about after Windows NT was shipping and the original IDE
drivers were built to work on the SCSI hooks, which already had most of the
necessary pieces in place to support drives with onboard controllers,
rather than the MFM/RLL/ESDI hooks which didn't.

This continued to work well, but eventually in 2K or XP (I forget which
offhand) Microsoft provided dedicated IDE support. Some manufacturers of
IDE chips have written new drivers that hook into the IDE support, others
have continued to refine their older drivers that hooked into the SCSI
support rather than starting over with new drivers that hook into the
dedicated IDE support.

Like that a system cares where the controller sits.

Any reference for this?

I think you are mistaken with standard (MoBo) IDE showing up as SCSI in NT.
Any addon IDE controller is sub-classed as SCSI on the PCI bus.
SATA on the other hand will have SATA as PCI sub-class.
