Hi. I found this website and openboard by typing in my problem on google, and i saw that sometime last year someone really found some solid help with fixing their dvd drive. I have a Toshiba Satellite Laptop that i bought in 2003, and for the past 6 months have had extreme difficulty with my DVD drive. It won't read any CD's or DVD's at all and keeps saying that the "request could not be performed due to I/O device error." Does anyone know how to fix this problem? I was reading that someone else was able to fix it by doing something called "regenit" in the "run" folder. I'm an aid worker in Pakistan and in desperate need of help as my work depends on this drive. Thanks.
