32 bit External Hard Drives on Vista

Let me preface my question with the fact that I have a very rudimentary understanding of computers.

I have a Toshiba Satellite with the following specs:
AMD Turion X2 Ultra dual-core mobile processor ZM-80; 4GB DDR2 SDRAM; DL DVD±RW/CD-RW drive; Labelflash support; 250GB hard drive; Windows Vista Home Premium 64-bit with SP1.

I am attempting simply to take music off an external hard drive, but have thus far been unsuccessful. The message that displays says something like "unable to read, 32 bit driver?"
Could anyone explain to me how I could reconcile my OS with the External so I can get this music?

Could you post the brand/model of the External Hard Drive? And it's connection . USB / FireWire etc...

The External I am trying to get music from is called Ceedo/FreeAgent and the connection is a USB.

I have previously had success taking some files off a Maxtor External through a USB with no problem
