Unable to change name of newer external HD on TimeMachine

I was unable to get this answered the first time I posted this so trying again in hopes. Below

was the discussion. If you don't have an answer, please send me a link to another website

that might be able to help. I've have this problem for some time now and getting pretty

frustrated.

I completed switching from old to new external harddrive, and everything went smoothly, and I'm able to backup and recover to new drive.

However, even after repeatedly changing external hard drive, by doing the following:

-Clicked on "select disk"

-Selecting the name of the new drive

-Clicking on "Use for Backup"

The name of the old external drive still shows up on Time Machine window.

I also have disconnected/reconnected the old external harddrive.

Any ideas why it still shows the name of the old external drive?

I tried to reset Time Machine > http://pondini.org/TM/A4.html

I went through every step very carefully from above link several times, making sure, that drive was disconnected, that time machine was off,

and deleting the plist file from mac->Library->preferences->com.apple.TimeMachine.plist.

However, whenever I reconnect drive the drive and select disk's new name, the old name still comes up.

I'm guessing it's reading the name of the old drive from somewhere, but not sure from where.

The com.apple.TimeMachine.plist file in step 5 is practically empty every time I check it.

5.Delete the file /Library/Preferences/com.apple.TimeMachine.plist

(in your top-level Library folder, not the Library folder inside your home folder,...

However, that same file under my acct->Library->Preferences has a lot of information, including the name of the old external drive.

Is it possible this is the one I need to delete without risk?

Does anyone out there have any ideas?
