Thank you very much, Stephen., that will help me to move forward greatly! I will have to wait for the morning to try it since I am formatting an old ESDI drive on the microvax and am getting lots of errors, have to wait and see if it can map the bad blocks for me to use or if I have to look for another one!
cheers,
Nigel
