Getting Data off a HDD from a WinXP PC

Hi.

I had Win XP Pro on a PC. I had a number of users set up to use the PC. My user account was the only one that required a password to get into Win XP.
The PC died so I removed the HDD and installed it in another PC as a slave drive. The new PC can see the whole HDD and I can get at all the data except that data which is under my user account. When I try to get at the data it says access is denied.

I know my password to get at the data, but no where does the new PC(running Win XP Home) give me a chance to enter that password.

Anybody have any ideas?

Thanks in advance.
