Urgent help required - IDE DRIVE

Hello - short on time.
My friends computer stopped working. He needs sensitive files OFF his desktop ASAP. So he's coming to my place tomorow and I'm plugging his DRIVE into my PC... However, his drive is IDE... my DISK DRIVE is IDE... I have ONE IDE CABLE... it would be possible just to temporerily swap the IDE SEATBELT CABLE to his DRIVE....right? Would there be any problems?
I understand I cannot boot from his drive, I'm booting from mine, then accessing his drive from my computer. How do I access files on Windows XP home, that are on another admin user account, on another drive? The files are on his desktop btw.
