So, I have completed the copy of the subset of the data to the USB stick. Two of the files were corrupted. I removed the two files and rsynced all the files from that day. No joy. I then ran a diff on them again and another file appears corrupted. It appears the USB stick is losing sectors.
I am happy to go get another USB stickand put the files on that. I could use one the smaller USB drives I have on hand and just copy and compress the files onto that.
If you have another solution, let me know.
