First, make sure the reader didn’t leave any grime on the memory card’s metal connectors that could affect the card’s performance. Also, make sure the or damaged. Finally, it’s possible the memory card has been corrupted. If you unplugged the memory card reader while the memory card was being read, causing a loss of electrical power to the card, it’s possible the card is corrupted. You should be able to fix the problem by formatting the card, which (unfortunately) will cause all of the data on the card to be erased.
1: is my multi-card reader. This internal driver was installed when I got my machine (originally with XP). I do not know what make it is but the machine is a few years old 2: is my Dell external floppy drive. It is not USB connected, I don't know what the name for it is but it is bolted in at the back.
