files don't load in Bridge

I recently upgraded the external hard drive where I save my RAW files to an SSD, and have about 2 TB of files on a 4 TB drive.  When I navigate to the drive in Bridge, the files don't load, the little circle on the bottom left of the screen just spins endlessly.  I realize it's a lot of data, but on my previous drive the files would eventually load pretty quickly, after navigating to the drive a couple times back and forth.  Now, not at all.  Any idea why?  Thanks.
