Windows 10: Possible HDD problem

Just had a scare...
A L W A Y S B A C K U P *Shock

I have a bunch of HDs in this box. I have a client HD that is a Seagate®NAS HDDST3000VN000

I was working on it and it disappeared. dskmgr said it had failed. reactivate did nothing. panic.
I took off the connectors, reconnected and it came back. Immediately started copying to an intel SSD (Older drive, NOT the OS drive)
This was the behavior:
It would ramp up to a decent speed 30MB/s and my PC was fine. Then it would ramp down to 0kb/S and the pc would start running slowly, really lagging. Click and wait.
Repeat. Finally it finished copying the critical data. the 80 was full so I started copying to another (new) SSD I have.
I assumed that the drive was dieing because it kept going down to 0kb/s but it just copied 30 gigs of data to the SSD with a consistent speed (130MB/s) and the PC did not lag at all.

I don't know if I need support or not but what is going on here? Has anyone ever experienced this kind of behavior?
I will run chkdsk and a seagate disk checker but I will replace the disks (I have 2 identical drives). they are cheap enough.

Hi Johan,

It is possible that your

• 
  Unhooked
  the
  HDD
  and

  PC.
  
• 
  Reconnect
  your
  HDD
  and

HDD Corrupt ?

Hi,

There are many possible reasons this issue is happening. We'd like to ask few questions below:

• What is the brand name of you Hard Disk Drive?
  
• How old is the HDD?
  

Since you already tried multiple troubleshooting steps, we suggest visiting the manufacturer's website. Find and download a hard drive diagnostic software to help resolve the issue.

Let us know how it goes.
