Merging Songs on 2 different hard drives

[Chuckster1936]

I have a PC and 2 laptops. I have imported CD's on each of these at different times. In so doing, I have BookID numbers with different songs and DiskID assigned to them. I have all this on 3 different external hard drives.

I would like to merge all these on 1 hard drive, but I lose the duplicate BookID numbers. Is there any way of renumbering the BookID, or must I indentify the Dups, and re-import each disk, which would be a monumental job.

My hoster is: 3.321, Windows XP, WD and Seagate 250GB and 320GB hard drives and a Seagate 1.5TB.
