100 Percent Disk Usage

[gengyuntx]

I added a brand new 14TB HDD to my system. Win 10

 

When I didn't put big files in the new disk the disk runs fine except sometimes it disappears from the system but after I restart the computer it works fine. 

 

It is when I start to add bigger media files (~2GB) to the disk it starts to give me problems; smaller files are fine (~100 MB).

 

The disk usage would stay at 100 percent and the system monitor tells me that the system is accessing that big file with 100 percent disk usage even after the transferring has complete. This makes the drive unusable. I could not even open the folder. I have two other HDD and another SSD in the system they all work fine. Is there something obvious in the configuration that is wired or is it a faulty hard drive? Thanks!

Sounds like its faulty.
