Disk Utility verfy found too many clusters allocated

I just purchaced a new LaCie firewire drive. While copying files over to it I got some errors. I ran Disk Utility "verfy" on it and got the following:

Verifying disk "LACIE".
** /dev/disk3s1
** Phase 1 - Read FAT
** Phase 2 - Check Cluster Chains
** Phase 3 - Checking Directories
/Desktop DF has too many clusters allocated
Drop superfluous clusters? no
** Phase 4 - Checking for Lost Files
1284 files, 1097600 free (2393596 clusters)

Verify completed.

Do I need to do a repair? Are these errors? Will repare delete the files I've already copied? I want to send this drive to my father in Venezuela. I need to make sure the drive is ok. The errors I got concern me. Should I re-initialize the disk? He is running OS 9 so I need to make sure he will be able to read it.

Thanks,
Alfredo
