Many many thanks to you for the hint - I added the On/Off switch on the adapter power and everything now works fine! I insert cassette, cycle the power and mount the drive - it works! Once again - many thanks. -- __________________________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup
