Thank you Mr Singer. This is the information sheet I had been trying to use. Bur still no success. I have got as far as numbers 6/7. Then ... Click on Erase. Done. Then there is the "Are you sure message ....?" Click on Erase Then Erase again. click on this and get Mounting Disk to erase. Then it is back to the original message. I keep going round in circles. And make no progress. Am I being dense? Thank you for your support. Keith Mills On 4 Apr 2011, at 23:25, Randy B.
