You likely won't be able to. But let's get more info first..

What is the full model drive? And how do you think it failed? Anything out of the norm happened?

The Model is "BUFFALO INC. (formerly MelCo., Inc.)" and when I plug it to Linux then it just show me an empty Hard drive but In Windows it ask me for format it. I did some Linux commands like "fsck" and "ntfsfix" but they told me that I must run "chkdsk" and after it Linux can show my Files but Windows can't. I want to know how can I understand that it is a software problem or hardware problem?

Thank you.

I would try running ddrescue to clone the drive to another one. If it can image all the sectors, then you know the hardware is good and can test things off the copy. Here's a tutorial about how to use ddrescue: https://www.data-medics.com/forum/how-t ... -t133.html

To test with limited free resources, I would try MHDD (http://hddguru.com/software/2005.10.02-MHDD/)

ddrescue is a Linux tool. Try MHDD (Dos). It will not try mount the drive or anything as it is a diagnosis based tool.

ddrescue allows for more flexibility with more switches/options, including the most critical - ability to skip "bad areas".
Try both on practice drives and see for yourself.
