I have two partition on my hard drive that is Drive C and Drive D. I have installed the Windows 7 on C drive and after installing this, I found that the Drive D is not accessible. I can see the both the drives but that is not accessible. Some of my friends told me to format the D drive and that will be accessible again but I have a lot of materials saved in that and I do not wish to lose those data from my drive. Can somebody tell me any alternate solution for this? Thank you in advance for replying.
