I’ve got a P4-3.0ghz,512mb ram,64mb video memory. My OS is win2k connected to a server. My problem is the message “unsafe to unplug device ” pop-ups in my screen. I don’t have any usb device plugged and it turns out the Samsung DVD/CD writer is the one having trouble. It is set to slave and i used one cable for the HDD set to primary. I noticed that system slows down while working in Arcview software. I checked the device manager and no conflicts shown. Please help. Thanks.
