I can't quite tell from your post whether you are trying to recover the data from the drive or just fix the drives as you have formated one already.

If you are trying to recover the data it may be possible but it can be tricky. You will need a replacement drive you can copy the data to once it is recovered.

You can use a tool called DDRescue (Note: DD_Rescue is a different older tool) to attempt to recoverer the data.

There is a good guide here on how to use it:

Best of luck.

Scratch that just re read your post and the contents were backup up.

In that case just bin the drives and replace.

If you are unable to format the usb because of write error, try doing a low level format.

Have you ever tried to safely unmount/eject your USB drive before pulling it out?

Yeah, as I mentioned earlier... you need to try a low level format.
