Thanks, thats what I needed. I followed those steps and the partition size looks good now.

I appear to have all the files back, but there were about seven I/O errors reported by 'dmesg' so perhaps something is corrupted. I was initially unable to format the card until I removed the virtual memory space I had allocated to it. That was still activated when I performed the copy so maybe that had something to do with the I/O errors (?)
