I'm having an intermittant problem my 4120B, in that when I insert the blank media into the drive the light will flash for a few seconds and then the mouse pointer will freeze on the screen. I have to reset the system every time which is getting really frustrating. The 4120B is the slave drive with my Samsung DVD-Rom as the master. Both drives are running in Ultra DMA mode 2.
I hope someone can help me solve this problem
