On my Toshiba laptop my TSSTcorp CDDVDW TS-L633F driver is not working in Windows 7. In the Device Manager, I get:
Windows cannot load the device driver for this hardware. The driver may be corrupt or missing (Code 39)
This is because Windows 7 uses a generic driver for the TSSTcorp CDDVDW TS-L633F DVD writer, which does not work. To fix the TSSTcorp CDDVDW TS-L633F driver error, find the correct driver for the DVD writer and install that.
Sorry, I don’t have the download link for the driver anymore. If you find it, please drop a link in the forum to help others.
