Norton Ghost 14 - Problem with incremental backup of external hard drive

Hi:

 

I have been using Norton Ghost 14 for a couple of weeks. During that time I created separate full recovery points for my internal C: drive and my external hard drives.

 

Now I have run a few incremental backups of the C: drive and the file size of the results appear to reflect only changes made to my C: Drive since the last backup. So everything seems to be working fine for my internal hard drive.

 

However today after downloading some MP3 files, I did an incremental backup of my external L: Drive which I use solely for MP3 storage. But the size of the incremental backup was practically the same as that of the original full backup. It should have been very small since I only made a few additions.

 

The extension of this backup is .iv2i which would indicate an incremental backup. But the size seems to reflect a full backup.

 

Can someone please explain to me what might have gone wrong here?

 

Thank you.
