The GCC 4522B does not have a SCSI interface. SCSI drives are no longer manufacturered. This one has an IDE/ATAPI interface.

If the drive is not detected by the os, eg: is not listed in My Computer or Device Manager, you probably need to do the "Delete upper and lower filters fix" in the registry.

Be sure to create a system restore point before doing the changes (or backup your registry file) as you can roll back if something goes wrong.

Troubleshooting CD/DVD-ROM devices in Windows 2000 and XP

Many third-party programs that control CD or DVD burning (as well as some player applications) install CD- or DVD-ROM filter device drivers into Windows. These filter drivers are meant to allow for low-level hooks into the hardware, to allow for functions such as packet writing (where a CD-R/W or DVD-/+RW can be written incrementally, like a hard disk).

These filter drivers sometimes have problems that can cause the CD or DVD drive to stop working correctly. The device entry for the CD or DVD drive in the Device Manager may show up with an error descriptor that reads "The device could not start." Additionally, there may be an error message that reads "One of the filter drivers for this device is invalid." The devices themselves do not show up in Explorer. Error codes for the device include code 31, code 32, code 19 or code 39, and sometimes the even more ominous warning "Your registry might be corrupted" appears.

Fixing the problem simply involves deleting the filter entries for the third-party device drivers. These entries can sometimes become damaged (which is what produces the "corrupt registry" warning).

To delete the offending keys, open the Registry and navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

-->Delete the keys named UpperFilters and LowerFilters and reboot.

Several of the products made by Roxio are infamous for causing this problem, although in fairness to the company the most recent versions of their Roxio CD/DVD writing software (6.2 and higher) do not have these problems. Users of 5.0 or 6.0 editions of the Easy CD & DVD Creator product, which has been bundled with many new PCs in the past, should upgrade to 6.2 or better. Other programs can also cause this problem, with the same solution.

Note that after you do this, you may lose functionality in the program that uses the filter drivers, which may need to be reinstalled, eg: reinstall your recording software.

There is also a file you can download that will do this procedure for you automatically. Just read a few of the posts below your to find it. eg: CDGone.zip
