I just bought a NEC ND-3540A today. And also a USB2.0 case because I am using a laptop.
The strange thing is, the driver will stop responsing after about 10~20 second running. For example, I copy a big file from DVD+R which was recorded by another DVD writer to my HDD, and 20 seconds later it stop responsing and USB connection lost. Then I changed to a DVD-R, the same thing happened. Last I tried CDSpeed to test the transfer rate, again about 15 seconds later it stopped. Each time I have to power off the writer and the power on, otherwise mp XP will not recognise it.
Could anybody guess what is the problem? I tried to set the writer as Master, Slave and CS, but it didn't help. Should I change a external casing?
