A Maxtor external hard drive is seeming to be interfering with other devices on this computer. It is a Maxtor Personal Storage 3100 (100 GB) with a USB connection.
The problem is that when the hard drive is plugged in, the Lexmark printer is not able to print or view pictures on the SD card.
On a laptop with Vista, the drive must be plugged in numerous times to be recognized and after it is recognized, the computer is knocked off the internet, possibly the entire network.
So, any ideas?
