Disk behavior symptoms opinion...

I have a situation that's weird. 

I have 12 disks. If I access any file on 11 of them on windows via share, it instantly opens. And of it's a video, scrolls fast fast forwarding or rewinding. 

 

But if I specifically chose and open a file on that 12th drive, it takes a long time to open. Video is slow to scroll. Sometimes it hangs for a good long bit before being resposive again.

 

As a test if I move a file from that disk to another via krusader, it works instantly again so I know it's not corruption.

 

Smart short and long checks have shown good with no errors. 

 

Is this behavior a precursor to failure?

Sounds more like a cabling problem (SATA or power) causing retries to happen on the drive.    You are likely to get better informed feedback if you attach your system’s diagnostics zip file to your next post in this thread taken after the issue has occurred on drive 12.
