I had connected a 20Gb hard drive of my friend. His system is crashed he wanted the data of his hard disk. Here when I try to open an copy the file a error pop-ups denoting access denied to the file. The hard disk is connected as slave in my windows machine. I tried to copy the files but still the error comes out. Is the hard disk corrupted. What are the other ways I can get the data. What is reason for this error. Thanks.
