Lg 4166b...need Help

I have two drives configured as Master/Slave on the second IDE channel…LG GSA-4166b(master) and a Toshiba SD-M1502(Slave) I use as reader. I’ve used the same drives in the same config for months and burned an untold amount of discs. The other day, I started to get errors on the burn end of the process over and over again. Since then I have formatted my HD and tried another drive (Plextor PX-716a)getting the same results. Using “ImgBurn”, this is the error and the log I get every time…

I/O ERROR!

Also, the LG Drive won’t recognize CD’s of any kind or many DVD’s (both retail and copied) and it’s listed on my puter as a DVD-RAM Drive. Any advice would be a great help and “Thanks” in advance!
