New cd rom doesn't work

Op sys can't find the CD rom anymore, A, C E and F drives are recognized but the D isn't even though the device manager shows it.

So does anyone have the Mother Board dip switch settings for the 300PL ?

    I swapped the original DVD rom with a RW and it worked fine then I switched back to the DVD ROM drive and that is when the D drive was gone. I have been in admin tools drive/disk mgmt and the D drive doesn't show up anymore only things that show up are A (floppy), C main, E: USB and F a second harddrive which was there from day one.

    I did disconnect the 2nd harddrive F and the USB E and try reinstalling the DVD but in this case all that was visible were A and C and still the BIOS showed the DVD drive as installed.

    The BIOS still shows the DVD-ROM drive but it's listed in slot zero with my C drive. I did check to make sure it was set for slave but it still won't recognize it.

    I did swap it to another slot and still doesn't work.

    I tried master and slave config on different cables but still it does not show up in admin tools disk mgmt; but as I said the bios shows it there.

    Lets see what else ?

    Oh yeah both the CD-RW and the DVD drives work in another PC so it's not a drive problem.

    Interesting when I go to admin tools / computer mgmt storage/removable storage/physical locations it shows the DVD-ROM drive as crossed out in red, IE disabled but I cannot enable it.

Have any you added any drives to your computer recently? If so you'll have to check the jumper settings on your drives. If nothing has changed to your computer between the time it was working and when it stopped then you most likely have a dead drive.

But since you say the device manager sees your drive you'll need to go into your administrator tools in the control panel and select computer management. Under storage select drive management. If you see your drive listed but has no drive letter you can right-click the drive and assign a drive letter. The change should be immediate.

Cannot boot from cd,code 5

First, make sure that the disk is not damaged, scratched, etc. Try putting it into another machine and see if it will boot. Next, make sure the drive itself is working. Will it play a cd, or let you "explore" it with windows explorer?
Check the device manager in the control panel under system (xp). Find the CD Rom entry and make sure that there isn't a yellow question mark by it (or anywhere else in the hardware list). Expand the CD Rom entry in manager and right click on the drive, then choose "properties" Make sure that drivers are installed and that windows reports it as working.

If everything checks out, then :You may have connection issues. Make sure the cables on both the board and on the device are snug and fully inserted. Do the same for the power cables.
If that doesn't solve the problem, try switching the cables themselves. They sometimes become damaged or otherwise degrade.

My computer no longer "sees"

at end of this instruction set, see link to review more questions/answers,as your issue with CD/DVD ROM will vary .

This document applies to HP and Compaq desktop computers with Windows XP, Me, and 98. Use this document to make Windows and the CD writing software recognize the CD or DVD writer drive. Start at Step 1; do not skip to other sections until Step 1 has been completed. Step 1: Does Windows detect the CD or DVD drive? Use Device Manager to determine if Windows is recognizing the drive:
  1. In Windows XP, click Start , and right-click My Computer . In Windows 98 and Me, right-click the My Computer icon on the desktop.
  2. In Windows XP, select Properties , click the Hardware tab, and then click the Device Manager button. In Windows 98 and Me, select Properties , and click the Device Manager tab.
  3. Click the plus sign (+ ) next to DVD/CD-ROM Drives (or similar) category.
  4. Do the following depending on what is listed in the DVD/CD-ROM drives category:
    • If the CD or DVD drive name is missing , the drive is not being detected by Windows. Close Device Manager and skip to the section CD or DVD drive is not recognized by Windows .
    • If a drive name is shown but is disabled (icon is marked with a red X, c00877300.gif ), the drive has been disabled. Right-click the drive name and select Enable . You may have to restart the computer to complete the enabling process. The drive should work correctly once it has been enabled. NOTE: If the drive cannot be enabled, a required service or driver that the drive needs is not functioning or has been disabled. Click the plus sign next to IDE ATA/ATAPI controllers and troubleshoot any problems found according to any error codes in Device Manager. Resetting the BIOS may also resolve this problem.
    • If a drive name is shown but contains an alert icon (an icon marked with an alert symbol, c00877301.gif ), then use the section Using Device Manager error codes to troubleshoot the problem. You may also use the next section Disc burning software does not recognize the original drive to reset the drive configuration.
    • If the CD or DVD drive is listed as normal but your disc burning software does not recognize the drive, Device Manager shows no special icons c00877302.gif . Windows is detecting the drive but the writing software does not. Leave Device Manager open and continue with the next section Disc burning software does not recognize the original drive .

Why does my lenovo insist on my having a cd rom when i have a dvd writer installed? how do I fix it so that computer recoognizes it?

I have the same situation. My computer has a
DVD-RW/CD-RW installed yet when it is empty, the computer simply recognizes it as a CD drive. However, it will automatically recognize any DVD I place in the drive. Even a blank DVD-R. So it's not really a problem for me.

Also, if you type in DEVICE MANAGER in your windows search area, it will show you all your computer's hardware and peripherals. I have Windows Vista 64 bit and in device manager it does recognize it as an ATAPI DVD under "DVD/CD-ROM DRIVES".

I haven't seen a DVD burner yet that won't play or write cd's; maybe this is standard.

I wouldn't worry about it as long as it performs the functions (play/burn DVD's?)

Hope this helps.8a17955.jpgb9e40e6.jpg

I'm putting cds into the drive but they won't run and when I go to 'My Computer' it's not showing the drive

Is it a new drive? Is the latest driver loaded for it? are the cables in correctly? are the jumpers set correctly? Is it recognized in the BIOS? If you answered YES to all but not even recognized in the BIOS then its the ribbon cable or the unit itself
