Having an issue with my Samsung RV511. I had to replace the screen on it and since then it does not load, says it does not see the hard drive. I have tried the Samsung recovery tool but it will not run it. I have tried to reinstall using the recovery disk but it does not see the hard drive to load it on. Any help would be great as I dont know a lot about the inner workings on computers. Afraid I may need a new hard drive. Thanks for any help.
