Milk,
If the XP drive is DEAD, you're not going to get anything out of it any way you connect it.
Now, if the drive is OK, but windows is screwed up, then you have some options.
Like was just said by 'Carbon Dudeoxide' , you should attach that drive to another computer as a slave drive and extract the files you need using Windows Explorer on the OS drive. Then the files could be copied to a Flash Drive or burned to a CD/DVD.
I perform this "Service" all the time for my customers.
From DOS you will NOT even be able to read the average Windows XP drive, because it will be formatted NTFS and that's
invisible to DOS. (Sorry, I didn't make the rules!)
However, if you have "NTFS4DOS" on your boot disk, it will allow you to read and copy files from an NTFS drive.
Due to this restriction, I NEVER set up any HD for XP on an NTFS formatted drive.
XP runs just fine on a FAT-32 drive and then I have full control over that drive, even from a DOS boot disk.
Good Luck to you!
