New DVD ROM drive, works but PC warns on boot up

[LWC]

Hi all,

I bought and installed the Liteon DH-20A4P-04 model. (The OEM version of DH-20A4P-08)

The DVD burner is working fine. The problem is that when I boot up the PC now, I get the error message that my old CD ROM Drive is missing. If I press F1 to continue and ignore the warning, the PC boots up fine and I have not noticed any problems. Windows Device Manager shows the DVD drive as installed and working.

However, I would like to get rid of the warning message and have my DVD drive recognized on booting up.

Does anyone have any suggestion what I have to do?

Thank you.

Go into BIOS setup and set all the IDE channels to AUTO DETECT.

I don't see the autodetect option in BIOS. The only option I have is to either enable or disable a drive. Under the drive 1 setting, BIOS says unknown for the name of the drive, as if it can't recognize my new dvd drive.

might be a bad cable/or an old 40 wire cable and the new drive needs an 80 wire ide cable.

What does it say for DRIVE 0?

One other thing to try, uninstall the channel the DVD drive is on and see if Windows properly detects it on a reboot. But since the problem occurs during the initial boot, the BIOS may be the source of it.

Windows XP had no problem detecting the new DVD. It's the BIOS.

Number Six, here is what the details for Drive 0 in BIOS are:

Control = SATA
Port = Sata - 0
Drive ID = 3T34...... [ID of the drive]
Capacity = 40 Gb
BIOS = Controlled by System BIOS
Link Speed = 1.5 Gb

For Drive 1 it's:

Controller = PATA
Port = Pata - 0 (Pri IDE Master)
Drive ID = unknown

My PC, which I bought used, is the Dell GX520 model (I think it came out around 2005). Is this too old for the Liteon DVD drive? (In regards to aedipuss' suggestion about the cable)

[redwudz]

If it's a PATA (IDE) drive, you definitely want a 80 conductor cable. If that's what you have, try a new cable. The older 40 conductor cables look similar to a floppy cable, just more conductors. You also want to make sure the drives jumpers are set properly, apparently as master if it's the only drive on that cable. Most optical drives come set as slave, so that can cause problems.

[Number Six]

As Redwudz said - Definitely check the jumper on the back of the DVD drive. Look at the jumper setting on the CD drive that you removed, and set the jumper on the DVD drive the same way.

This really does not make sense since you only have 1 PATA optical drive installed, it should accept it as a master or a slave

[LWC]

The jumper may be the problem! The old cd drive has the jumper at "cable" and the dvd drive has it at "master."

I am going to change it tomorrow and see if the warning msg goes away.

I don't have any pliers handy. What's the next best tool to safely remove the jumper?

I don't have any pliers handy. What's the next best tool to safely remove the jumper?

Fingernails. Tweezers. Hemostat.

[redwudz]

I use a bent paperclip and hook it underneath and extract if I don't have any needle nose pliers handy.

[LWC]

changing the jumper fixed the problem!

Thanks guys!

I guess that Dell does something strange with the BIOS settings, forcing Cable Select.

Glad it is working OK now.

Even the burning is much faster now. It took somethng like 40-50 mins to burn a dvd before at max speed of 16x. Now even at 8x, it took me 8 mins to burn the first dvd with the jumper set correctly.

[Number Six]

That is because it was not working properly - the BIOS knew something was attached, but it did not know what it was, or how to use it. Although Windows was able to recognize it, it did not have the right settings to work correctly so it was assigned the most minimum resources. Actually, I'm really surprised that it worked at all with the jumper set incorrectly

Enjoy
