“Could Not Perform End Of Disc-At-Once Error” is an error message that appears at the versions of NERO (DVD/CD Burning Software), when we want to cover data on a DVD/CD.
If you will return NERO on the whole parts and you will test more version, you will notice that the error persists, and if you finally choose to use Windows DVD/CD Burner (Tool Default of Windows 7 and Windows XP – Windows Explorer (Write these files to CD)), there are weak chances that the operation of writing data on DVD will be successfully completed. Tested by me.
For those who use Windows 7, DVD's writing errorthe some causes may occur:
1. First of all, physical problems of the optical unit. DVD/CD RW defect. (The problem can be regardless of the operating system used, and the solution is in change of the optical unit. At laptopURLs Toshiba It changes very simple. A screw is broken, then draw Optical unit outside.)
2. DMA (Direct Memory Access) Mode is Off. Disabling the DMA greatly increases the writing / reading time on the optical unit, and this is often the main cause of “Could Not Perform End Of Disc-At-Once Error“.
ENABLE DMA (Direct Memory Access) in Windows 7.
a. Click-right on Compuer > Manage
b. Device Manager > IDE ATA/ATAPI Controllers > Identifies Cananul Ata (ATA Channel) al DVD/CD RW optical unit and do click-right on it > Properties.
ATA Channel 5 In my case.
c. In ATA Channel Properties > Advanced Settings bifam la “Device Properties” > Enable DMA & OK.
After DMA activationRelieve the process of writing the DVD.
3. Update Firmware DVDRAM.
It is very possible if you have an older optical unit (2-3 years), firmwarethe (control and control software of the unit) to have undergates with the launch of the new operating systems.
It is advisable to identify the exact model of the optical unit and search the manufacturer's website if there are firmware updates for that model.
How can we find the DVDRAM model.
Either from “Cumputer Management” > “Device Manager” > “DVD/CD ROM driver“…
… or click-right on DVD Drive in “Computer” > Properties.
HL-DT-ST DVDRAM GSA-T50N ATA – The model of the optical unit in the above screenshots.
On most models of laptopSITES Toshiba of the series Satellite A200 and A300 There are such DVDram optical units.
Download Firmware Update HL-DT-ST DVDRAM GSA-T50N (RP07).
Download > Extract > RUN GSA-T50N_RR07.exe (double-click) > Click on the button “UPDATE”.
Wait until the Community UPDATE process is completed, after which click on “REBOOT” to restart the computer.
The above would be the main causes of Writing and reading errors data on DVD/CD-uri (Could Not Perform End Of Disc-At-Once Error), but there are situations where poor quality or Physical deterioration of discs (scratches, marker spots or other substances on the disk writing surface) to prevent the process of reading / writing on disc.
