Someone plzz help.. Here is wat happnd. There were two hard disks connected to my pc and both were running fine until I connected another hard disk of my frnd's removing the previous secondary hard disk. And that's it!!! I am not able to boot from my primary hard disk at all!! Just before booting it shows a message "Primary Master Drive Fails". I changed the IDE cables and did all permutations but to watever slot (Primary master/slave or Secondary Master/slave) i connect the hard disk. it just shows the same message and boots from any other available drive. I have some real important data and I am in trauma of missing all of them.. Please provide some solution and tell me if you wanna kno some more details.. Thanks in advance.
