which errors? Waiting for hard disk activity to reach threshold level ?
its not an error , just info .you can disable it in settings .
maybe your hdd and burner share the same cable?

maybe but your problems are related to your media choice which isn't verbatim
look under help->imgburn logs or if the programme is running just press 'L' on your keyboard.
firmware updates add new discs to the drives write strategies and improve on existing strategies on some discs
verbatim and taiyo yuden are the best. dont take our word for it , look here http://www.digitalfaq.com/media/dvdmedia.htm
tests done on this forum on your media http://forum.imgburn.com/index.php?showtopic=580 show it to be inconsistent
if you do as mmalves describes above , after the layer break choice window appears and you have made the layer break choice , you can either burn direct to dvd or make a new iso/mds on your hard disc, its all explained in the guides section.
if it is connected to the mb it should be reporting ata so i would say its a bios setting (raid confusion maybe) or drivers
edit:
is the ide port intel or jmicron?
