I'm asking for help because I am really losing my patience now. Ive tryed on 5 f---ing different CD's, of two different marks, and it always give the same result, when it reaches 20-50 percent, I get this stupid error message that says Session Fixation Error. I used Nero 5.5.10, and I attached my log to this post. Now if you have the solution please help me because I'm really losing patience and I absolutely need to make a backup of my files before I format. --------------------- Windows XP 5.1 IA32 WinAspi: - ahead WinASPI: File 'C:\Program Files\Ahead\Nero\Wnaspi32.dll': Ver=2.0.1.59, size=160016 bytes, created 2003-01-29 22:37:36 Nero Version: 5.5.10.42 (Nero Express) Recorder: <MSI CD-RW MS-8340S> Version: 120D - HA 0 TA 1 - 5.5.10.42 Adapter driver: <atapi> HA 0 Drive buffer : 2048kB Bus Type : default (0) -> ATAPI, detected: ATAPI CD-ROM: <MSI CD-RW MS-8340S> Version: 120D - HA 0 TA 1 - 5.5.10.42 Adapter driver: <atapi> HA 0 Bus Type : default (0) -> ATAPI, detected: ATAPI === Scsi-Device-Map === DiskPeripheral : Maxtor 6E030L0 atapi Port 0 ID 0 DMA: On CdRomPeripheral : MSI CD-RW MS-8340S atapi Port 0 ID 1 DMA: On DiskPeripheral : Conner Peripherals 420MB - C atapi Port 1 ID 1 DMA: On ======================= AutoRun : 1 Excluded drive IDs: CmdQueuing : 1 CmdNotification: 2 WriteBufferSize: 40894464 (0) Byte ShowDrvBufStat : 0 EraseSpeed : 0 BUFE : 0 Physical memory : 255MB (261616kB) Free physical memory: 74MB (76052kB) Memory in use : 70 % Uncached PFiles: 0x0 Use Static Write Speed Table: 0 Use Inquiry : 1 Global Bus Type: default (0) Check supported media : Enabled (1) Wizard: Off 22.7.2004 CD-ROM (ISO) 15:16:07 #1 Text 0 File Isodoc.cpp, Line 7589 Iso document burn settings -------------- Determine maximum speed : FALSE Simulate : FALSE Write : TRUE Finalize CD : FALSE Multisession : TRUE Multisession type: : Start multisession Burning mode : TAO Mode : 1 ISO Level : 1 (Max. of 11 = 8 + 3 char) 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 15:16:07 #2 Phase 72 File dlgbrnst.cpp, Line 1655 BURN-Proof activated 15:16:07 #3 Text 0 File Reader.cpp, Line 115 Reader running 15:16:07 #4 Text 0 File Writer.cpp, Line 125 Writer MSI CD-RW MS-8340S running 15:16:08 #5 ISO9660GEN -11 File geniso.cpp, Line 4571 First writeable address = 0 (0x00000000) 15:16:08 #6 Text 0 File Burncd.cpp, Line 3745 Turn on Track-At-Once, using CD-R/RW media 15:16:08 #7 Text 0 File ThreadedTransferInterface.cpp, Line 672 Setup items (original item values) 0: TRM_DATA_MODE1 (CTransferItem) 2 indices, index0 (150) not provided original CD pos #0 + 22089 (22089) = #22089/4:54.39 relocatable, CD pos for caching/writing not required/required, no patch infos ----- 15:16:08 #8 Text 0 File DlgWaitCD.cpp, Line 225 Last possible write address on media: 359844 (79:59.69) Last address to be written: 22088 ( 4:56.38) 15:16:08 #9 Text 0 File DlgWaitCD.cpp, Line 230 Write in overburning mode: FALSE 15:16:08 #10 Text 0 File DlgWaitCD.cpp, Line 1700 Recorder: MSI CD-RW MS-8340S; CDR code: 00 97 15 17; OSJ entry from: Ritek Co.

I think the clue is the "no seek complete" error message (it is the first error)investigations lead to the following from another site and not written by me http://www.mp3machine.com/discussion/messages/10913.shtml I got the problem when I try to erase no-name CD-RWs. I think it is atleast in part because of a dirty lens - let me explain to you why I think so. Every part of the CD is provided with a laser power calibration area - here's the spot where the laser adjusts its power to suit the medium. If the lens is dirty or foggy or whatever, it's too "hard" for the cd-rw or cd-r to be written. Sometimes the Cd-re/writer gives up and tells the computer "No seek complete". I suggest cleaning your lens professionally - not with those cleaning discs they don't even do a good job. They'll need to open it up and clean the lens and objective mirror etc etc. This is just my guess though. Try it out! Techy n Welsh

Well thanks for trying but I just spent 45 minutes opening my PC, then my CD burner and I saw no fog or grease or dust of any sort. So I guess that's not the problem.
