It says on the drive "Enhanced IDE Hard Drive"
Well...unless your new Win7 system has an IDE port (unlikely), you'll have to go through other means.
Fortunately, there are multiple options...
A
USB-SATA/IDE dock, or
USB-SATA/IDE cable (I use one of these all the time)
Or, a
PCI-E IDE card.
How large is the old drive, and what space do you have available on the new system. It is often advisable to just get the cheap cable option, copy your personal data to the new system, and move on.
After that, you can format the old drive (you don't need the XP install anymore) and possibly use it as a once a week backup.
