My DVD/RW Drive is not reading DVD discs, when I go into 'Event Viewer' in 'Administrative Tools' I see this error -

The device, \Device\CdRom0, has a bad block.

What the hell does that mean, and is there a way to fix it.

My Warranty on my Acer laptop has just expired too, and now im getting this.

I have a Acer Aspire 5633WLMi if that helps.

Hi, did you try multiple DVD's?

What do you mean?

More than one DVD?

Yes sorry, I have tried a few, still doesn't work.

Whats that error mean?

To save me typing lol

The device, \Device\CDRom0\, has a bad block


Usually this error is the result of a failing DVD drive, or faulty media. Try this:

I: Reinstall the device driver
==========================
1. Restart your computer.

2. Press F8 when the computer finishes Self-Test and begins to load the
operating system.

3. Select Safe Mode and press enter when the boot menu appears.

4. Right click My Computer on the desktop, and click Properties.

5. Click the "Hardware" tab and then click the "Device Manager" button.

6. Expand the "DVD/CD-ROM drives" item.

7. Right click your DVD device and choose Uninstall.

8. Click OK to proceed.

9. Restart your computer. The computer will automatically detect the
device and install the driver.

II: Remove the upper filter and lower filter values from the Registry
================================================== =======
1. Click the Start button, click Run. Type Regedit in the Open box and
then click OK.

2. Browse to the following key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11C
E-BFC1-08002BE10318}

NOTE: This is the CD-ROM/DVD global class key.

3. Delete the upperfilter and lowerfilter entries if these strings are
present.

4. Restart your computer and check if the problem disappears.

III: Hardware issue
=================
If the problem persists after trying all of the above methods, it may be a
hardware drive issue. Please check if the DVD is physically damaged.
