Best Way to Transfer Music Between USB Harddrives

I recommend Windows Robust Copy then use Beyond Compare for subsequent updates.

In the example below:
F = source
E = destination

Create a text file with the lines below the -- then rename the extension to .bat.
Double-click the .bat file.

This will copy all files and subfolders from 1 to the other.
You'll also have a log of all the files it copied.

--
C:

robocopy "F:\roger waters" "E:\roger waters" /e /mir /np /log:backup_log.txt

exit

+1 for Beyond Compare. I'm even going to pay for this gem when my trial is up.

It's pretty good value. I've been supporting them for years. Maybe 20 or so? Basically, you pay up and can install it on as many machines as you personally own. Multiple platforms in my case. Free minor version updates, and they don't muck around with a paid major version update every year like some other companies. They've been been supporting and improving version 4 for years now. So they treat their customers well, thus I am happy to support them in return.

Indeed, Beyond Compare is a nice piece of software I had heard about it but never really pursued it, the comments here helped like any new software there is a learning curve, but it works well.
I actually bought a license. Thanks To All.
