Hi, Had a good look round the forums but couldn't see anything specific to my problem. I've got: Dell Lattitude C610 Windows XP Prof. Nero express 220.127.116.11 Samsung sn-308B combo cd writer/dvd player External (usb) NEC 2510a I have no problems burning both data and music CD's on both drives. However, if I try to burn an image e.g. cue/bin or ISO, the external writer (NEC) works - BUT the samsung drive dosen't... it burns, verifies, but is a coaster maker! - tried different media, CD-R, CD-RW, reducing speed x4 instead of x8 - but still no joy. Can anyone help? note: I've also just updated the fireware of the samsung drive.....no change. cheers in advance.
