Thanks for the help and terminology definitions. I already have a CD/DVD/BD optical disk unit in the PC. The Plextor drive is an external USB3 attached drive. That USB cable is the one the LG unit was attached to. I could search for an internal replacement with the LG functions. Had two separate read/write units to make disc copy easier. Spent some time researching an internal replacement. Seems like all of them have problems relative to manufactures media support or reliability. Also, saw a report that SATA is slower than USB3. Anyway, will continue to pursue the drive or even the PC hardware as the problem area.

ImgBurn.log I think I did it right this time! Slow learner

Forgot to attach the log file.

Windows 10 Home. Optical Disk Drive: LGBE14NU40 External Blu-Ray Writer USB 3.0. Microsoft driver 6/21/2006; 10.0.105 86.0; 32 bit. Is connected to a USB 3.0 port. From error messages, looks like firmware is at 1.01. Device list ID = “O”. Using ImgBurn V 2.5.7.0 to write in test mode which does send the data to the LG but the laser is turned off. (1) Powered up PC. Open ImgBurn. Write 10 GB ISO file to LG unit. Went thru the write ok. (2) Repeated the write option again. Got to “Synchronizing buffer” at end of write and ImgBurn error: “Synchronise Cache Failed”; Device: [0:0:0] HL-DT-ST BD-RE BE14NU40 1.01(O:)(USB); Reason: The Semaphore Timeout Period has expired. Had to CAD to close ImgBurn . The LG unit is now offline. (3) Cycle power on LG and unit comes back online. Start the write action third time. Software shows the buffer filling (not the device buffer yet). Nears 100% full and get an “I/O Error”. “Interrupted Write (12) Sectors 0-31”; “Reason: device not connected”. The File Explorer list does now show that the LG unit is offline. (4) Cycle power on LG and it comes back online. Start the write operation the fourth time. Got a repeat of “(2)”. This time clicked on “Cancel” three times and got “CreateFile Failed!; Device: ‘\\?\usbstor#cdrom&ven_hl-dt-st&prod_bd-re_be14n40&rev_1.01#prolificmp00000001d&0#{53f56308-b6bf-11d0-94f2-00a0c91efb8b}’: Reason: The system cannot find the file specified. I was using a Plextor optical disc unit prior to replacing it with the LG (wanted to be able to write M-discs also). The Plextor worked fine on the PC and Windows 10. I just got the LG unit so have no idea if it would have worked ok with previous Windows versions. At a total loss to identify the problem area. Any suggestions? What is a “Semaphore”? Is the “Timeout” an option value? Why is the device taken offline after the errors and what software does this? ImgBurn shows two buffers used; a “buffer” and a “device buffer”. Where are these buffers located (drive or PC)? Where is the “failed cache” located? What “caches” are being synchronized?.....and so on. I did not have any other programs running during this testing; however, there may have been some “services” running in the background. ​I doubt there is any problem with ImgBurn; however, maybe someone has encountered this problem and can direct me to the right support area. Thanks.

Thanks for the information. Just got the LG BE14NU40 which does support both media formats.

Does ImgBurn support BDXL and M Disc media? Joe

I use "write image file to disc" to place a commercial player format on a disc. I use "write files/folders to disc" to build a data disc. My question is, how can I place both file formats on the same write once discs? As an example, I wish to place a travel video playable on a commercial player and add in the TIF images used to build the video. The latter is in case someone would like to print a quality, large image of presented in the video.

Image Burn V2.5.6.0 with Windows 7 Home Premium Service Pak 1. Optical disk device = Plextor PX-LB950UE attached to PC via USB 3.0 and Rosewell PCIe card. Write data files on blu-ray disc. Verify write data. Disc is JVN-Tayo Yudin 6X. Starts the write process and randomly fails fairly early in the write. Here is one error message: Device (0:0:0) PLEXTOR BD-R PX-LB950UE 1.02 (01) (USB) Scsi Status = 0x02 Interpretation = Check Conditions CDB: AA 00 00 07 C7 60 00 00 00 20 40 00 Interpretation = Write (12) - Sectors = 509792 - 509823 Sense Area = all zeros No additional sense information For this example, the progress window shows 5%, write speed=2x, write retries=20. All drivers and software up-to-date. Have run all the Plextor checking utilities and see nothing wrong between the utility applications and device. My question is, what is the failure data telling me?
