I use Windows 8.1 and I have problem in one of my external hard disk drive. It is showing shortcut and files are hidden. I opened the hidden drive icon and found all the files except a folder of 15 GB. That's a very important folder for me. I used attrib -h -r -s /s /d g:\*.* but shows access denied system volume information. I don't know what to do, i really need to recover the folder. Please help, this is urgent, I have assignments to complete.
