I have a desktop with an Intel motherboard running Windows 7. A few days ago I bought a 2nd internal hard disk (SATA Seagate 500GB). I installed it and it was running normally. I copied some of my very important data on that new hard disk from my old internal hard disk whose data was deleted from the old hard disk.
Now for some OS problem, I had to reinstall Windows 7 on that old hard disk as it was before. The new hard disk is no longer showing in My Computer. How can I recover the data from the new HDD?
