Q:
Yesterday, when I attempted to copy something on my hard drive to the burn disc in DVD-RW, something happened, the DVD-RW seemed not be recognized in BIOS, besides, in device manager, there’s no DVD-RW. The door is open, so I inserted a disc, but it seemed that the DVD-RW couldn’t read data any more. Device manager cannot find the existence of DVD-RW, why is this? Hope to get your suggestion and help. Thank you very much!
A:
1):  Suggest you entering BIOS and inspect. If it could inspected, then system software doesn’t recognize it, if couldn’t, it’s the problem of hardware. Solution for the situation if it could be inspected: enter device manager and delete IDE controller and then restart the computer. If it’s still unsolved, then reinstall system.
2): Click “My computer”—“Management”—“Disk management”:
Check up whether the DVD-RW is under the disk, if yes but drive volume is lost, then reallocate a volume for it: right click the DVD-RW—change volume and path—choose a volume and done.
If the DVD-RW is not existed, then it means the computer cannot recognize it: right click “My computer”—“Properties”—“Hardware”—“Device manager”—find the DVD-RW from the list, uninstall the driver and then uninstall the device, refresh the list and auto install, done!
If the steps above don’t work, then you need to pull and plug the data cab
