How to Restore Data from RAW External Hard Drive?

“I need some help in recovering data from my 1TB Seagate external hard drive. It has about 800 GB data including music files, photos, videos, movies, applications and documents. I think it is an NTFS file system but started out by showing 0 bits free of 0. I have tried changing the drive letter and letting the Windows to scan and fix the drive. It is now visible and showing 200 GB free of 1TB. Although when I try to open the drive, I get an I/O error. I tried using a data recovery tool, but it shows that it will take 672 hours to scan. The most important thing I wanted to do is to get back files from external hard drive. Thanks for any help that is given to solve this issue!!!”
