TDK 880N CD DVD R/RW Does not read ANY media

[BlaineIII]

After cleaning my system of spyware using several registry and anti-spyware
free and shareware programs, AND after getting a message on reboot saying that ElbyCheck has detected a corrupt Filter Driver PxHelp20
This driver will prevent your CD-Roms to work properly.
I took the option to delete this file. I rebooted and found that
Windows XP could no longer find my CD ROM which is a TDK 880N DVD CD R/RW device. I resintalled "CloneCD" that did not help. I finally found that the power connections were loose, then my system could read the device, Nero, Roxio and Windows XP shows the TDK 880N DVD CD R/RW device is online, BUT it will not read ANY blank, or pre-recorded CD DVD or any that I have burned.
I tried deleting all references to the device and the two ide channels out of Device manager and letting the system search and find the device but it still could not read any discs. I tried deleting upper and lower filter referencesin the registry but that did not help. I un installed and reinstalled Nero but that did not help. I updated the Firmware for the TDK 880N DVD CD R/RW but that did not help.

I found three references to TDK 880N DVD CD R/RW in: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\I DE\CdRomTDK_DVDRW880N___________________________1. 36___
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\I DE\CdRomTDK_DVDRW880N___________________________1. 34____

I removed the last one removed the last one but the others could not be removed.Just as well for I had backed up the registry but now I cannot restore the backup to the registry.
