I bought a western digital 4tb external hard drive and was planning on transferring all of my office's files on it from a my passport 1tb western digital portable hard drive.
First i plugged in the 4tb external hard drive and then it installed the drivers and everything was working fine.
Then i plugged in the 1tb portable hard drive and i only saw one of the two partitions come up. Also when i tried to view files on partition that came up the windows just freezes and then the partition diappears and I unplug and replug it to see the same result repeat.

I plugged the portable hard drive into other computers without the 4tb one plugged in at the same time and still the same thing happens.

I have extremely important data on it for my office and i don't know what to do.
How could a partition just disappear and why cant i view the files in the partition that is showing up.

Please can someone help me ?!??!!
 
It looks like the drivers may have been "mixed up" with the drives. Try rebooting, then plug only the 4TB drive in and see if everything is there. If not, try reinstalling the drivers for it.

Next, I would try to transfer the data from another machine using a share across the network.
