Cannot build my database

[Ramblin]

I have been using my laptop for a while to do my Karaoke shows. Yesterday I added 75 new songs to my 16,000 song 500 gig hard drive. I did this on my desktop computer like always. Then I backed them up to my secondary 500 gig hard drive. When I got to the club, I told my laptop to build the songs database. It gets to about 700 songs and slows way down. After about 100 songs going through real slow (about 15 minutes) it speeds up and stops now and then to tell me there was an error. I did chkdsk on the hard drive and defragged it. That didn't seem to do any good. I put the hard drive back on my desk top computer and used it to build the database and it worked fine. Then I put it back on the laptop and it did it again. I uninstalled Hoster and reinstalled it again, but it is still doing it. Any ideas about this?
