I need to find a good free utility to do a checksum on the contents of a USB stick that has multiple directories and files.  Unpacking a Visio 2013 .ISO (with 7-Zip) to this USB stick and then using to do installs.  Sometimes the USB stick is missing files during install time after made.

I want a utility that can give me a checksum on contents of USB stick made each time to make sure it has all files etc..

Thanks

I tried the md5sums program but it only gives checksums for files in a directory and does not traverse each folder etc.. I looked at command line options and tried wildcards but it only does the files in top level USB drive folder.

Also, this program would give me a list of all files with check sums (if I can get to traverse all folders automatically) but then I need to find a way to tell if the output is the same each time (as I compare two USB sticks made).  I guess I could capture output to a file and then run a Unix like diff command but I am using Windows 7..  Not sure where to get a good free version of that (the pc-tools.net does not list one..

Thanks

That shouldn't happen, perhaps your anti-virus is disallowing some files. (I think 7zip has a verify option).

Instead of CRC checking, you could try this free file/folder comparison utility ...
