I take it your computer is running OK on the new disk. If so, take your old drive and change the jumper setting to show it as "SLAVE" To do that there should be a diagram on the label side of the drive that shows "Master" "Slave" and "Cable Select" jumper settings. On the back of your drive - where the big ribbon cable plugs in - look to the left and you should see a small rectangle with little plastic jumper over two of the pins. If your drive didn't give you a diagram look right under that jumper either on the case or sometimes on the printed circuit board itself and you should find (M) for Master (S) for Slave and (CS) for cable select. The jumper just slips over the pins and can be gently lifted out and placed in the (S) slave position. Now put your drive back in your computer without disconnecting your present drive (That means now you'll have two (2) hard drives. The computer will recognize the added drive and automatically set a Drive letter to it. Go to "My Computer" and you should see it listed. Make a note of the drive letter. Now you can copy your files anyway you like and then, if you choose, format it and have all that extra space. Remember if you format it you will lose the date so be careful. If the disk is actually "physically broken" you will get an error message. Hope this helps
