My Compaq internal CD-ROM drive stopped reading disks after I tried to delete the Sonic Record Now! software. I didn't realize this software was important to keep on the hard drive. So far, my research indicates I need to do something with the Upper and Lower Filters folders in the registry, but I am unsure about what specifically needs to happen.

Hi,
For that problem, Try first replace that internal DVD-rom drive other good internal DVD-rom drive. if not Also Detected or recognize.
Try this second solution. insert external USB type DVD-ROM. if not recognize also, Your operating system Have internal software device data corrupted. You need to reinstall operating System like windows xp, windows 7 (OS) etc.. to fix data Corrupted of operating system device for hardware software.
Please see sample external DVD-rom USB type.



Just let me know if not yet working your Compaq Presario 700 series DVD-rom Drive.
Thanks for using Fixya.

click start control panel,administrive tools,computer management,device manager scroll to cd/dvd rom drives right click properties then properties again then tick enable cd digital cd audio for this cd rom device or scroll to dvd regions select the no _ for your specific area
you might have to install the burning software you used to burn the data to the the disc to be able to read you might have to copy the software to a USB drive if you can not read a cd/dvd

hope this helps

Sonic is typically a cd burner software. look for any CD utilities running down by the clock and right click on the icon to exit them. Maybe look for a sonic or CD/DVD software package that would have come on a disk with your computer , insert it and re-install the package, that may do it for you. If the nag is tooo annoying, for the interim look in your start menu under startup and delete anything in there that is in relation to sonic or cd writing software. Hope that helps you. Cheers

The drive has NOT been able to read the directory of the disk you put in.

Possible causes:

Disk may be a DVD which your drive may not be able to read.
Disk may be a DL DVD (double layer) whcih your drive may not be able to read.
The disk might be a BluRay which your drive may not be able to read.
Your drive may be defective or have a dirty read head.

Hi,
Check the cd-rom power is on or not. Then also if its not reading then Insert an DVD/CD cleaner disk and follow the steps. The cleaner disk is available in any of the computer shops. There may be some lens problem. After trying above steps if again same problem occurs then you need to replace the cd/dvd rom drive. Thank you.........

Hi, if the PC's are older than 3 years or the cdrom drives are near it's end of life, it will make problems to read some CDR's. If you recorded the CD's you are trying to read, try recording at less than 4X speed.
Sometimes, even "original" or "silver" CD's will make problems because they are not recorded correctly at the factory.
If the problem is with a CDRW drive, it applies the same theory, the recording laser is damaged or used up. It will not record a legible CD or DVD even if the software says that the record operation ended successfully.

if you have deleted the cdrom, just restart your pc and it will find it on the boot up

hi try taking a air can spray with a nozzle and clean the laser eye other option is to buy a more quality CD's good luck
