I have a few hard drives in this mac pro tower 10.9 Mavericks - they show up in Disk Utility but will not mount. DU shows a sort-of "blank document" or "unidentified filetype" image instead of the normal icon for external media.
 
I used CCC to migrate data from a 3TB drive to a 4TB drive on a computer running a 10.8 Mountain Lion - and then (with the hard drives disconnected) upgraded that machine to 10.9 Mavericks. Since re-connecting, they will not mount. However, they will also no longer mount if I place them in a NAS connected to my MacBook Pro running 10.6 Snow Leopard. 
 
Both yes, are over 2.2 TB in size.
 
They used to work before (and connected to each other via shared folders, etc, etc.

disk0 is the System SSD - running smooth as butter.  disk1 and disk 6 ("Medias") are the culprits.  they will not mount and Disk Utility shows them as having "0 folders and 0 files" - although showing they're actual disk usage/capacity. disk 2 is a Windows installation (doubt its relevant though) disk 3 and 4 are USB sticks, and disk 5 is another drive equivalent to the "Medias"

try boot with the USBInstaller and go to UTILITIES/DiskUtility and REPAIR the disks that you have problem, or you can try from Maverick or ML the app Disk Warrior to repair it

 

 

Good Luck!!!!

DiskWarrior said it fixed things, but nothing actually changed

It "mounts" with 0 files and folders - but you can see that the files are taking up space. It doesn't every actually show up in Finder either. - DiskUtility says I can "unmount" it but it never popped up into the Devices list in Finder. This is rather weird

try copy a file from the disk with of terminal app

 

cd /Volumes/Media 2 

then a ls

 

then copy  any file to the desktop

 

 

EDIT: more easy to you

 

open diskutility and app Terminal

 

now in terminal app type

cd                      and pull the disk from disk utility to window of the Terminal,  +enter

 ls

and see if display yours files
