OK, I am trying to figure out how to make a HD activity light , using power from the HD. I am going to use a small 80 meg IMB HD as a test unit: http://www.storage.ibm.com/techsup/hddtech/wds2/wds2jum.htm Reading the above docs it says a LED can be run from pin 8, then to ground. After looking at all the drive's docs... where is ground ? And for that matter, how do you specify a SCSI address using these types of drives ? I am expecting 2 pins per address jumper..... Assuming I can find the ground, then I can build a circuit: Drive LED power ---->resistor---->LED----->ground although I am not sure how to choose a resistor (power from the drive is 100mA max). thanks, Mad Dog ---------- Duo/2400 List, The friendliest place on the Net!
