What does it mean "the volume has the wrong case sensitivity for a backup"?

I am trying to transfer my backup data to a new hard disk and I get this message.

WD 3TB External Disk-OTHER, Mac OS X (10.6.8)

Most likely the new disk needs formatting. Some are factory-formatted as case-sensitive. Macs normally don't use those. Just erase and format it as Mac OS Extended. That should allow you to use it with for your backup data.
