I am having a problem with CloneCD doing an on-the-fly copy of dual-layer discs. When I use My Asus DRW-1814BLT SATA burner, with a Verbatim 8x DL disc, I get the following error : Image doesn't fit on destination Disc! Space available: 5546 MByte Space required : 4482 MByte Firstable, the message is reversed - the source disc is 5546 MB, not 4482. But also I am using a DL target disc, so I shouldn't be getting this message at all. I am using the latest 1.14 firmware for the Asus burner. I am able to burn the DL disc just fine in the DRW-1814BLT in other programs like Imgburn. The problem is only in CloneCD. If I put the DL disc in another burner - Samsung SH-S182M IDE with latest SB06 firmware - then CloneCD does not complain, and the DL backup works. Any idea what's going on ? FYI I am using Vista 64-bit SP1, Intel Q6600 CPU, P35-DS3R, and the Gigabyte SATA/IDE controller from that motherboard for my optical drives.
