Hi. i have an hp 655 with a 320 gigabytes harddrive. my laptop was a bit unstable and wanted to format the harddrive and re install a fresh windows 8 pro. So i opened the laptop, removed its harddrive and connected it to another laptop to save my important files and connected back the harddrive to my 655 to completely format and install a new windows. after installing the windows, i removed the harddrive from the hp 655 connect it as an external to copy back the files i had saved to in another laptop. Unfortunately i did a "cut and paste" to the harddrive. Now when installed the harddrive back to my hp655 it boots normally but i cant access any of my old file. The used space indicates they are there but i cant access them even if i search the harddrive there are no matches. Please help.
