In some way to get the info off of it. If it is a bootable drive then install it as the master drive. If the drive is not bootable then it will have to be installed as a slave to the master. You will need A CD/RW or DVD/RW drive to put the data onto a disk and a program that does that such as Nero or CDBURNER XP PRO, You can google for both, the latter is free. If the data is small you can also use a flash drive.

Once the info is saved you can use the XP/OS cd to format the drive, that will clean the drive but not completely to anyone that wants to go to great lenghts to recover the info. I use DBAN (google for it) to wipe the drive. If you want you can go to my profile and send an email for additional help but it's up to you.
