I have a problem with my two LiteOn IHAS124 E (FW: 4L06, 4L07, 4L0A... chipset: Mediatek MT1882n... buffer size:768 kb).
When I try to do a surface scan with Nero CDSpeed/DriveSpeed 4x/5x/7x on a data CD-R the scan speed stays below 0.5x and red dots appear periodically.
All other CDSpeed functions and the surface scans on DVD-R and audio CD work fine. Surface scans with Plextor PX-880SA and LiteOn IHAS124 W (FW:HL0F... buffer size: 512 kb) on a data CD-R work fine too.
Could it be an incompatibility between CDSpeed/DriveSpeed and the Mediatek MT1882N chipset?
Sorry for my english
