Hello, all. Here's the program I used to test various ATAPI transfer lengths based on the sample code Daniel Drake posted a while ago. The code Daniel Drake posted was taken from brasero and had the following bug. Byte 7 is high byte of alloc size not low and the whole CDB should be ten bytes long instead of nine. SPC tries to trick you here by omitting byte 5 in Reserved field. Daniel, care to forward this to brasero developers? Thanks. -- tejun
