(Copying from here: http://forums.afterdawn.com/t.cfm/f-47/nero_fails_-856946/) Nero fails to write dvd-r disks but does write dvd-rw disks... WTH! I've updated my firmware and nothing changed. Actually I think it writes all old disks. It used to write dvd-r disks fine 2 days ago... I guess some smartash in the dvd industry dicided to change something on the dvd disks... Any ideas on how to solve this ??? ---------------------------------------------------------------- ahead WinASPI: File 'C:\Program Files\Ahead\nero\Wnaspi32.dll': Ver=2.0.1.74, size=164112 bytes, created 26/10/2004 7:35:32 μμ Nero Version: 6.6.0.19 Internal Version: 6, 6, 0, 19b (Nero Express) Recorder: <_NEC DVD+-RW ND-6650A> Version: 1.43 - HA 1 TA 0 - 6.6.0.19 Adapter driver: <atapi> HA 1 Drive buffer : 2048kB Bus Type : default (0) -> ATAPI, detected: ATAPI CD-ROM: <_NEC DVD+-RW ND-6650A>Version: 1.43 - HA 1 TA 0 - 6.6.0.19 Adapter driver: <atapi> HA 1 === Scsi-Device-Map === DiskPeripheral : FUJITSU MHV2100BH iaStor Port 0 ID 0 DMA: On CdRomPeripheral : _NEC DVD+-RW ND-6650A atapi Port 1 ID 0 DMA: On CdRomPeripheral : AXV CD/DVD-ROM 2.2a a347scsi Port 2 ID 0 DMA: Off === CDRom-Device-Map === _NEC DVD+-RW ND-6650A D: CDRom3 AXV CD/DVD-ROM E: CDRom1 ======================= AutoRun : 0 Excluded drive IDs: WriteBufferSize: 83886080 (0) Byte ShowDrvBufStat : 0 BUFE : 0 Physical memory : 1022MB (1046636kB) Free physical memory: 409MB (419092kB) Memory in use : 59 % Uncached PFiles: 0x0 Use Inquiry : 1 Global Bus Type: default (0) Check supported media : Disabled (0) 28.6.2010 Μεταγλώττιση ISO 8:01:45 μμ #1 Text 0 File Isodoc.cpp, Line 6368 Iso document burn settings ------------------------------------------ Determine maximum speed : FALSE Simulate : FALSE Write : TRUE Finalize CD : TRUE Multisession : FALSE Burning mode : DAO Mode : 1 ISO Level : 2 (Max. of 31 chars) Character set : ISO 9660 Joliet : TRUE Allow pathdepth more than 8 directories : TRUE Allow more than 255 characters in path : TRUE Write ISO9660 ;1 file extensions : TRUE 8:01:45 μμ #2 Text 0 File Reader.cpp, Line 127 Reader running 8:01:45 μμ #3 ISO9660GEN -11 File geniso.cpp, Line 3309 First writeable address = 0 (0x00000000) 8:01:45 μμ #4 Text 0 File Burncd.cpp, Line 3233 Turn on Disc-At-Once, using DVD media 8:01:45 μμ #5 Text 0 File DlgWaitCD.cpp, Line 272 Last possible write address on media: 2298495 (510:46.45, 4489MB) Last address to be written: 2254671 (501:02.21, 4403MB) 8:01:45 μμ #6 Text 0 File DlgWaitCD.cpp, Line 284 Write in overburning mode: NO (enabled: CD) 8:01:45 μμ #7 Text 0 File DlgWaitCD.cpp, Line 2494 Recorder: _NEC DVD+-RW ND-6650A, Media type: DVD-R Disc Manufacturer: MBI 01 - RG40 Disc Application Code: 64, Disc Physical Code: 193 8:01:45 μμ #8 Text 0 File DlgWaitCD.cpp, Line 450 >>> Protocol of DlgWaitCD activities: <<< ========================================= 8:01:45 μμ #9 Text 0 File ThreadedTransferInterface.cpp, Line 838 Setup items (after recorder preparation) 0: TRM_DATA_MODE1 () 2 indices, index0 (150) not provided original disc pos #0 + 2254672 (2254672) = #2254672/501:2.22 relocatable, disc pos for caching/writing not required/ required, no patch infos -> TRM_DATA_MODE1, 2048, config 0, wanted index0 0 blocks, length 2254672 blocks [_NEC DVD+-RW ND-6650A] -------------------------------------------------------------- 8:01:45 μμ #10 Text 0 File ThreadedTransferInterface.cpp, Line 1051 Prepare recorder [_NEC DVD+-RW ND-6650A] for write in CUE-sheet-DAO DAO infos: ========== MCN: "" TOCType: 0x00;
