Time Machine and Boot Camp/XP

When using Time Machine, does it also back up the info on my Windows portion of my hard drive? I use Microsoft Money on the my iMac and it seems the hard drive is dead - using the disk utility it sees no problems with the Windows partition, but an Invalid Node Structure on the Mac HD.

I'm not so concerned (other then the major pain in the...)with the HD loss on the Mac side, since I use Time Machine and it's backed up, but I'm beside myself if I loose all that Microsoft Money data!

I feel there is a HD problem with iMac, as my friends HD died on the same timeline that mine has, but that's another discussion.

Thanks in advance for any help!
