I have a 3 TB Seagate External HDD. It is NTFS. I have Windows. It crashed in the middle of my backing it up.
Now, it is recognized, even showing up sometimes with Total and Used space in the "My Computer" listing of drives as well as the acknowledgment of the NTFS file structure
However, It wont read from Explorer and generates an "I/O Output Error" in response
I have tried Chkdsk, but it says the drive is RAW and the Chkdsk is not available.
