DVD drive read errors

Hi Everyone,

 On my Win XP Pro SP3 computer , I have a Samsung DVD-Rom SD-616T drive, with the latest firmware :F310 . My problem is that recently, the drive 

won’t read DVDs, but it will read Cd’s just fine. But the drive will go back and forth between reading DVDs or not. Right now it won’t read DVDs at all.
I looked in computer management/event viewer/system , and saw about 16 of these errors :

Now my question is , what is causing a bad block of memory ? And how can that problem be fixed ?
Thanks.

Hi,

the drive can’t read the inserted disc properly. That’s why Windows reports a bad block.

If cleaning the lens does not help, then it’s time to replace the drive.

Today I purchased a Maxell DVD Lens Cleaner, cleaned the drive now it’s reading disks ( DVD’s) just fine.
