I am currently using a Toshia Techra 8000 (Windows 2000) and am having issues with my cd/dvd drive. While troubleshooting the hardware, I was given the following message, "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)". It then told me that the associated device is not working and if that was corrected it should work. I assume that the associated device would be the toshiba cd/dvd device that loads the the drive? This is my first question... what is the associated device? Thinking that it was an issue with the drive, I decided to try an alternative. I am trying to install a Sony Dual RW Drive (Sony DVD RW DRU-710A USB Device). I had no problem downloading the drivers for the external drive. However, I keep having the same issue with the toshiba cd/dvd. I get the code 31 message and the information about the associate device. I would appreciate any help, information, guidance, facts, etc. that you can provide to me I realize that this is a discontinued model but it is all I have to use right now. Thanks for all your help!
