[qanda]This question is published in the hardware section for the Sony DRX-820U. Click here to view full specs.[/qanda]I’m unable to use the Sony DRX820U DVD burner; the device is not recogonized. I tried to use the 1. Windows trouble shooting but it did not work; “No drivers are installed for this device. If you are having problems with this device, click Troubleshoot to start the troubleshooter.” 2. i also tried upgrading the driver (using 820UL_20D.zip) but got a message stating “HL-DT-STRW/DVD GCC-4241N It will be updated fromÂ A100Â ToÂ 2.0d Â The drive is not allowed to be updated.”
Hi and Welcome!
please try the unit with another computer.
Either there is something wrong with its hardware, or something does not work with your computer’s USB setup.
Bad components of the drives could be:
- USB cable (easily to replace)
- internal USB/IDE chipset of enclosure
- power supply unit of enclosure
Thank you for replying; let me check and I will let you know how things go.
let me add this:
In case you are using an USB hub, try connecting the drive directly to your computer.
I have had a dying USB hub, which also caused recognition problems.
