I have been using Record Now Max version 3.01 and also recently version 4 - Both exhibit the same error when trying to burn/copy a data disc in the DVD format. I have the following system: Panasonic DVD-RAM LF-311 drive OS: Windows 98/2000 PIII 1.0 GHz 512MB's Ram ATI Radeon 7000 AGP Vid card All patches and upgrades as well as drivers are current. I have also run the drive and software on another system and I get the same errors during recording/testing. When I try to test burn or burn it stops midway through the recording or testing phases and ejects the blank disc with the following error: Terminated with Errors Error -10 at Sector 1230864 Command 55 Sense: 05 ASC: 26 ASCQ: 00 Usually I am able to run a test burn till about 50% completion before the recording fails. In the above error message the sector address changes per burning attempts but it is always the same error message. I have installed and tried burning using Record Now Max (both versions) on two different systems - one running Windows 2K Pro and another running Windows 98SE - I have adjusted the drive cables and ran the drive as a master on a separate IE bus as well as in every combination as a slave/master on both primary and secondary buses with the same results. I have also tried disabling shadow bios via the bios settings with no avail. I have also tried using other software such as Gear Pro DVD 6.0 and Nero version 5, same results but in a diferent error message. Any help in this matter would greatly be appreciated.
