I have a 1TB external seagate backup plus hard drive. yesterday, I carelessly just unplugged the hard disk even though I got some sort of an unmounting error when I did it. Now, the hard disk doesn't appear on any system! I tried it on windows, Mac and Ubuntu.
The filesystem of the hard disk is NTFS. The disk also shows up on the boot menu when I restart. It simply doesn't mount I think. Could this be due to some corrupted NTFS file? Can I fix this on windows using chkdsk?
