If I understand correctly you want Timemachine to backup your external drive too, right?
How is the drive formatted? FAT32 or NTFS? You need to format the external drive in HFS+ or time machine won't back it up.

I think that most drives are NTFS factory,
Go to Applications>Utilities>Disk Utility. Then select the Drive and format it to HFS+. That should do it. Is this a Western Digital or Maxtor External Drive?
