I have been having a problem with my Samsung SH-S203D DVD burner. Whenever I try to verify an iso that I have burned with ImgBurn, I get an I/O error... Timeout on Logical Unit. This always happens at about the 70%-90% mark, regardless of the iso that I try to burn. The burnt DVD always seems to work fine... but I just find it strange that I have this problem when verifying the burn. I had a similar problem when verifying with Nero as well, and when using CDCheck. I also sometimes have problems with reading burnt DVDs on this drive which work perfectly on other computers. I am using decent quality DVDs, have the latest firmware and BIOS and am burning at either 4x or 8x, with the same results.
I appreciate any advice! I'm not sure how much of the ImgBurn log I should put in here, so here is all of it:
