First off you HAVE to determine which HD the MM Database is 'linked' to,
once that is determined use that drive's VSN and change all the other hard drive's VSN to match it.
Scenario:
You have 1 internal and 3 external hard drives.
The 3 external drives have two partitions E: & F:
All partitions are mirrored/identical on all three drives.
You plug in a single external drive and build your MM.DB from it.
Then shut down Media Monkey.
Copy the MM.DB file from \application data\MediaMonkey
to the root of E: on all three external hard drives
You then add the following entry to the mediamonkey.ini file.
[System]
DBName=E:\MM.DB
Now the easy part.
Open a command prompt and type E:\ and hit enter.
Then type vol and hit enter.
Listed will be something similar to this...
"Volume Serial Number is 58CA-F9CF"
Write down that alpha-numeric string.
Repeat for F:\ and write down that string also.
Download the following program....

Hard Drive Serial Number Changer
[Note: Windows 8 is not listed, but am using Win8 Enterprise Evaluation and it worked flawlessly.]
Use the program to change the Volume Serial Number on the other two drive's partitions
[E:& F:] to match the Volume Serial Number on your "original database building" hard drive.
All your drives partitions now have identical Volume Serial Numbers.
You have now successfully 'fixed' the issue of Media Monkey deciding to
tie the database to a drive's Volume Serial Number instead of a drive letter.
Now when you are in the middle of a wedding, and your primary hard drive crashes,
you can 'hot swap' your drives without having to rebuild your database or
Locate Moved/Missing tracks to get rid of the 'gray', while your guest wait and wait and wait.
ps...you may have to assign/change the drive letters E: & F: to the other two external drives,
using the
C:\Windows\System32\diskmgmt.msc tool.
I did not have to, but I have had to with other systems.
In your case [assuming all songs are located on your internal laptop's HD] you should
change the VSN on that HD to match the VSN of the HD that the database is 'linked' to.
Good Luck
