I'm having a weird problem with my 811S. Reading CDs and DVDs is no problem, but when I try to burn a disc, my PC freezes somewhere in the process on every 2nd attempt. I started removing any virtual disc drives, AnyDVD, even set the drive back to RPC-2 status but to no avail. Basically what happens is I start burning, and at some point the drive LED turns orange, and the PC freezes without warning. I thought maybe Nero fucks up again so I started making ISO images and burning them in DVD Decrypter and just when I thought things were finally working again, I also started getting freezes. Sometimes, even reading DVD-Rs that I previously burned leads to freezing (with the same symptom.. LED is steady orange). I use the latest drive firmware (HS0J I believe) but this has happened with the HS0E as well, and both Nero 6.0x and Nero 6.3.x. My dad got me thinking it might be a heat problem since the drive is in a Shuttle barebone, but I'm not sold to that idea yet.. the system temp is normal and the system is rock stable (7 days of 24/7 encoding should speak for itself), no crashes, no freezes, no anything except for when I'm burning . Is the 811S very heat sensitive? If so I suspect someone else must've made the same experience.
