I just repaired my card reader for the sticky wheel problem and after a few tries, got it back together. Thanks to everyone who has posted ideas on this site about this repair (I used model airplane tubing). Now the problem. I can write a program to a card, clear the memory and then read it back in, so I know the reader is working. What I can't do is read all my old cards. When I run them through, I get a checksum error, or a card error message. Sometimes I get the 1 of x message, but it still won't read. I have run the red cleaning card through, but it does'nt seem to help. And the cards are clean.
Any ideas would be appreciated.
