Most likely one of 2 things, both having to do with cable connections.

1. Power connection not connected/fully seated. If this is the case, the drive doesn't open, is not seen in BIOS, not seen in Windows. Reseat the 4 wire power connection to the drive

2. Data cable not connected/fully seated. In this case, the drive will open, but is not seen. Reseat the data cable.

How does P4 Connector connect to the CD Rom Drive

Hmmm, P4 is usually a designation, for a 4-pin ATX +12 Volt power cable,

I see though that they have P2 as the 4-pin ATX +12 Volt power cable, and P4 as a SMALL 4-pin Peripheral power cable,

This type of power cable is used on a Floppy Drive, or a Card Reader.
Not a Harddrive, or Optical Drive. (CD/DVD drive)

The Standard 4-pin Peripheral power cable, is used on an IDE (PATA) harddrive, or optical drive,

Rounder corners on the Top of the plug connector.
Only plugs in, in one direction.

Owner's Manual > Page 109 -
Power Supply DC Connector Pin Assignments

P1 = 24-pin ATX main power cable,

P2 shown above - 4-pin ATX +12 Volt power cable

P3, P5, and P6 are SATA power cables,

If you have a SATA optical drive (CD/DVD drive), the above is the power cable used.

Uses a SATA data cable,

SATA data cable connector on motherboard, is shown below the SATA data cable.

Color does NOT matter

What is the cd rom drive letter on a dimension c521

Microsoft Windows XP?

1) Left-click on Start
2) Left-click on My Computer

Look at the drive letters.
Local Disk (C:) is for the Harddrive.

If you have Local Disk (D:) this is for Recovery - Windows files, on the harddrive.

If it states Drive (D:) it is for the optical drive (CD/DVD drive)

If you have Local Disk (D:), then Drive (E:) is for the optical drive.

If there is no drive letter that corresponds with the optical drive;

1) The power cable to the optical drive has become partially unplugged,
2) The data cable has become partially unplugged,
3) The data cable is bad,
4) The power cable isn't giving out any power. (Use a different power cable from the Power Supply, IF available)
5) The optical drive is bad.

[Driver: A small piece of software that allows the Operating System to communicate with a device.

Windows XP Media Edition is the O/S.
The optical drive is the device ]

A) Left-click on Start
B) Right-click on My Computer
C) In the drop down list left-click on - Properties - at the bottom.
D) Left-click on the Hardware tab.
E) Left-click on Device Manager

F) Left-click on the + sign to the left of - DVD/CD-ROM drives.
DVD/CD-ROM drives is NOT listed? Stop. Instructions after this part.

G) Right-click on the name of the optical drive.
H) Left-click on Uninstall

A Microsoft 'squawk box' will come up,
"Warning you are about to uninstall this device"
Click on OK. (It is OK I assure you)

Now close all windows, and go back to your desktop screen.
Restart your computer.
(Start > Turn Off Computer > Restart)

When Windows fully loads again, you should see -
"Found new hardware"
And perhaps "Found XXXX device"
XXXX being the name of the optical drive

Then it is time to go to Dell Support, and download AND install THE driver for your optical drive.
Post back in a Comment for this, and I will guide you step by step.

No Drive Letter for the Optical Drive in My Computer:
You need to check if the power cable has come loose, from the optical drive.
You also need to check if the data cable has come loose, from the optical drive.

No? They are tight?
Then try another power cable from the Power Supply, IF available.
Try using a different data cable if you have access to one.

More than likely the optical drive is bad.
(NO DVD/CD-ROM drives listed in Device Manager)
A CD/DVD drive is a mechanical device. It only has so many hours it can be used.

For additional questions, or to have me clarify anything I have stated above, please post in a Comment.

you have either one of these ..

5187-5619 = DVD-ROM/CD-RW combination drive - 48X CD-R write, 32X CD-RW rewrite, 48X CD-ROM read, 16X DVD-ROM read

EL436-69001 = 48X DVD-ROM CD-R/RW optical drive - 48X read, 32X read, 48X read, 16X max write speed

make sure you buy CDs or DVDs which are speed compatible to your optical drive or COMBO drive speeds

if you are busying compatible speed CD media, then take some compressed air (can) and clean the drive bay and inside the optical drive area, to dedust it .

go to this site and review all the related sites .. read carefully and try to figure out what the possibility (issue) is .

if ALL this fails, you may have to replace the DRIVE itself

i hope this helps

My CD-rom will not work after inserting CD's or DVD will not rev-up what wrong and what should I Do I Have Inspiron 531????

1.The laser optical eye of the CD-ROM drive may be dirty, and needs cleaning.
If the optical eye is dirty, it won't read the information on the disk you install.

A) Computer on, Windows loaded, open the tray of the DVD-ROM drive. (Or DVD burner drive. Whichever drive you are referring to. DVD-R/RW)
Shut the computer down normally. (Start>Turn Off Computer>Shut Down)

Unplug the computer from power.
Use a can of compressed air fror computers, and spray air into the DVD-ROM drive.

The optical eye, is located on the bottom of the DVD-ROM drive. (Or burner drive)
The opening in the bottom of the tray, that comes out for your disk, is where you spray the air.

You won't be able to see the optical eye, so how will you know you are spraying the air at the correct place?

If you start at the front of the bottom of the DVD-ROM drive, and work your way towards the back, you will clean the optical eye. Spray across from side to side, and in rows, as you proceed towards the rear.

(Air will make it's way through, and reach the optical eye. The optical eye is not visible, as it can be harmful to the human eye when operating.
When the tray is closed the optical eye is exposed. It is not exposed to where it can harm the computer user.

More information that may be helpful, in understanding where the optical eye is located,

Scroll down to the heading - CD-ROM drives. Also view the photos down on the right, and the animated GIF.

How a CD Player Works. Same principle for your DVD-ROM and DVD burner drives )

2.Make Windows reinstall the drivers.
This solution requires physically removing the flat ribbon cable from the back of the DVD-ROM/DVD burner drive, then reattaching it.

Software advice of Updating the drivers, Rollback the drivers, or downloading, and installing the drivers, doesn't always work, or doesn't work.

If the physical solutions I am providing here does not work, we will proceed to the software solutions if you wish. (Comment)

1.Computer off, and unplugged from power. Open the computer case,

Dell Support - Dell Inspiron 531 Desktop PC - Manuals - Documentation - Removing and Installing Parts,

(Removing the computer cover)

BEFORE you reach inside you need to relieve your body of Static electricity!

Not trying to freak you out, just needed to catch your attention.
Static electricity, can fry out the delicate computer hardware components, inside your computer.

Touch the metal frame of the computer case.

Computer unplugged from power you are safe.
Touch the metal frame of the computer case, (AFTER you unplug the computer), the computer is safe.

In the above Manual documentation - Removing and Replacing Parts, click on - Drives

Scroll down to the heading - CD or DVD Drive
(Towards the bottom of the page)

Unplug the DATA cable from the CD-ROM drive.
(No.2 in the illustration)

[The two optical drives you have are SATA drives. Dell indicates you have a DVD-ROM drive, (Plays CD's and DVD's), and a DVD burner drive.
(Plays CD's and DVD's, and records)

DVD-R/RW is a 'Burner drive'.

If the information above is correct, you have a SATA power cable, and a SATA Data cable.
(The Data cable transfers information from the optical drive, to the computer, and vice-versa)

The SATA power cable connector, is longer than the Data cable connector.
The power cable connector has 15 pins.
The Data cable connector has 7 pins.


Scroll down to the heading,

Look to the right at the photo. This is a SATA Data cable, and it's connector.
Yours may not be a bent 90 degree elbow, but it will have the L shape in the connector, and 7 pins.

Scroll down to the heading Power Supply. Look down to the right at the photo of the 15 pin SATA power cable connector.
This is Not the cable/connector you want to unplug.

Unplug the SATA Data cable from the optical drive you're referencing to.
Press the Power On button in, and hold it in for a count of Five seconds.
Let go of the Power On button.
Do this two more times.

Plug the SATA Data cable back in.
Close the computer case.
Plug the computer back into power.
WAIT 1 minute.
Turn the computer on. Try the drive.

All dvds will not play in dvd rom on xps400

You can start from checking its general status (it is not clear from your description of the problem).
The first you can check if the drive is visible to the system
With WinXP it is in menu Start\Control Panel\System\Hardware\"DVD/CD-ROM drives" like in this picture, for example:
With Vista it is in menu Start\Control Panel\System\Device Manager\"DVD/CD-ROM drives". If you see it - click on it and check its status: "This device is working properly" or not.

If it is in the system, it should be visible in MyComputer as a disk drive as well. If yes (and still not working) then try another known-good drive to hook up to your computer and if it works - there is most likely a problem with your drive on hardware level -your drive need to replace it. If the known-good one does not work either - something is wrong on the motherboard or power supply (check power supply by pressing CDROM eject button - it's supposed to get open/closed if it is powered). For complete clarification you can check your CD-ROM with a known-good computer.

If system does not see it - you'll need to check its wire connections (switch off the power and unplug the computer case power cable before opening the computer) - there should be power (coming from power supply) and data cables (usually coming from motherboard) hooked up. The drive can be either IDE or SATA type - check to see how the cables look like.

If the both cables are connected, you can check BIOS: in the beginning of booting you'll need to press an indicated button to enter Setup (usually it is either "Delete" or "F2" buttons). In BIOS you'll need to check setup related to CD-ROM or/and IDE if anything funny is there (they should be OK by default).

That's practically all what you can do about it. You do not need any special software for accessing data files as photos or docs - the disk should be visible in MyComputer just as any other data disk. For video and DVD - MS Windows Media Player is fine.

I hope it'll help.

Can't reboot Compaq/Presario desktop, (power supply is working)

If the system recovery disk doesn't work it usually mans that the hard drive is bad. I would change the hard drive and use the system recovery disk on it after replacement.

Dvd/cd writer, and dvd rom drive does not work

Check if you have both cables attached to the CD/DVD drive. There are usually 2 that needs to be connected: the SATA or IDE (that ribbon-like connector that goes right to the motherboard), and the power supply (a connector that has 4 colored lines going to the power box). Make sure they are snug, and if necessary, try changing them with others that are known to work (there should be lots of spares). If the CD/DVD light blinks or powers on upon boot, it means power line is OK, but data cable connection is bad.

Dvd rom won't work

You forgot to check the jumper settings of the Hard Disk and the DVD Drive found at the back near the IDE and power cables. If you are using one IDE cable, then one jumper should be a Master, that's the Harddisk, and the DVD drive a Slave. If you are using two IDE cable then both must be Master.

You should check also the Harddisk jumper help settings printed on them, some harddisk needs the jumper settings for Slave presence on the same IDE cable.

If it doesn't work then It's either the cable or the DVD drive has a problem.
