xtacbyme,
I read quickly through this thread, but I am still unsure of what exactly you have now (or before if you already changed the file locations) and what you are trying to accomplish.
What is the total size of your media files (in gigabytes) and how big is the new drive? If you bought a significantly bigger drive, would the most straightforward method be to copy all folders and files to the new drive as they are on the old drive using Windows Explorer and just fix the drive letter with the Rename, Move, & Copy Files tool inside MC? (It can optionally apply the changes only to the database.)
After testing that everything works as intended you could delete the files from the old location and get lots of free space for other things.
I just consolidated the media files from three almost full 300 GB drives to one new 1 TB drive. The drive has now only a bit over 100 GB of free space, but probably, when the time to upgrade comes, I can buy a 2 GB drive for the same price I paid now.
In addition to installing a new internal 1 TB drive I copied the contents of the new drive to a new external 1 TB USB2 drive that can be used with any PC. For now, the three old 300 GB drives are in a shoebox and serve as an additional backup set. Later on I'll revice my backup strategy, because I always want to have two, quite up-to-date backup sets of my media files.
