hello
i had a big problem with disc read errors too. I bought a new dvd writer (the cheapest one here LG GH-20LS/22LS) and burn on verbatim dvd-r with 8x and i had not one error message since that.
whats up with u hdd. Are u working with FAT32. This can not work with files over 4 gb. U have do convert one partition in ntfs and extract the iso file in this partition. And u need space.
