External HDD FAT32?

How do I confirm that my Western Digital ‘My Book’ external 1tb drive is formatted as FAT32? Is there a way to check while it’s plugged into my Windows XP laptop? I want to use it as my USB storage drive. Will this drive work for that?

If it’s relatively new it’s probably formatted in NTFS. You can easily reformat in FAT32 by following the guide here:
