I have a 1TB Toshiba Canvio Basics 3.0 Portable Hard Drive. After Plugging it in, a check disk window pop upped and I chose the option to automatically fix file system errors and scan for and attempt recovery of bad sectors but was interrupted because a friend of mine got impatient and clicked cancel. after that, my hard drive became inaccessible. When I tried opening the hard drive an error message appear: Corrupted Hard Drive the Parameter is incorrect. after searching for a solution on that problem, I found sites which said that using cmd chkdsk on the hard drive might fix the problem. so I ran chkdsk using cmd and I think it got interrupted again. I left it alone for half a day and when I checked it again, the cmd was gone. I assumed that it was already finished running chkdsk but when I tried accessing my hard drive again It now said that I need to format the disk before I can use it. when clicking cancel, an error again appeared: Location is not available. A: is not Accessible. The volume does not contain a recognized file system. Please make sure that all required file system are loaded and that the volume is not corrupted.
Any Idea how to fix it? Is it still fixable? All my important files are there so I'm a little worried. I appreciate all the help that I will get.
