The new ones worked fine. Thanks for all your help, and to the others who advised me. I found that the drive worked in the end - I'm not sure what did the trick, I sprayed the contacts with Contact Cleaner, changed the drive to a different bay, took the drive out of its tray and re-installed it using Torx screws (though I'm sure the last made no difference). -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland
