I have installed windows using Hp Recovery Disks to WD Black 2 installed in my Hp pavilion lap to as primary HDD. After that it worked well and i installed WD Black software and got the 1TB HDD also. Later yesterday i used recovery disks and done a factory reset and format and installed windows again.Problem is now it has 1TB+ partition and 26GB recovery partition from HP also. Now i can not install WD Black software also. (It gives no WD black is found) How to reset my WD Black to original state?
