The progress bar in clonedvd does not show the % and after some time I get the 10 11 w2 error. The disk actually does burn and windows recognizes the disk as being xx gb. This only happens on 1 of the 2 drives. The other drive burns fine(& the progress bar does fine also). This problem drive I just installed replaced a previous one that burned fine also. This drive is set with same jumper setting as previous one (CS). I Have been using clone & any for a couple years with little real trouble but this ones new to me & I have come to a stand still on this. WINXP SP2 Have reinstalled CloneDVD 2909 & ANYDVD 6160. No upper filters lower filter is ElbyDelay AnyDVD Media tried TayoYunden 8x -r & memrex 2x -rw Region setting in windows is 1 Problem drive is a (Sony NEC) Optiarc AD7170A OEM 1.02 fw. (found a 1.03 update but states it is only for retail & bulk drives not oem) Jumper setting= CS Have done a driver update for ATA/ATAPI controllers--Standard dual channel pci ide controller.(used the standard)? Should I use the intel by intel OR intel by microsoft? The other drive is a NEC ND3520AW 3.07 (& is working fine other than not wanting to recognize some newer commercial DVD's) BURN SPEED has no effect. Thanks for anyones help.
