EDIT: New discovery! It seems there is something about idling that's getting to it. If I load a program immediately as after the OS is finished loading the speed is perfect and phenomenal! But if I wait for say half an hour or more before loading anything from disk its dirt slow. I suspect windows 10 is doing something on it if its left for idle too long

I have a SSD as main disk drive for frequently used applications and OS (windows 10) and a second HDD 1TB Seagate barracuda.

The SDD is fine the problem is with the HDD

It has the exact same issue as it was with the previous unit before it was replaced:

Early on the Disk was running fine for about a month or two but recently it became slower than dirt. Any read write action would lead to 100% disk usage with barely a few KB of data transfer actually happening.

I in the Task manager I noticed it was msmpeng.exe scanning it all the time which is window's antimalware tool , so I added the drive into exclusions for it so that it no longer scans the disk leading to disk usage because of it, but the problem stopped only temporarily

Opening a large file like a video is so slow that the playback become choppy as the system struggles to read the file as it is being played. It sometimes becomes universally slow as in anything that uses the drive becomes dirt slow as well, including de-fragmentator , chkdisk , image thumbnail generation or any disk check utilities.

I used seatools on it and did pass the SMART check

Since it was sealed packed and everything like its predecessor I don't suspect a vendor foul play yet, but rather something wrong with the configuration of the system or damage from a faulty power supply etc.

I will assume you mean that you are talking about your new 1TB Seagate.

My workday involves plugging hard drives into workstations for data destruction. Often, I come across hard drives that have the following problems that do not raise any errors from S.M.A.R.T. tests:

  1. Very slow random write speed. This could be due to internal resistance on the spinning platters or resistance on the read/write head. Read speed is about 20% percent faster than the random write speed on a normal hard drive.
  2. Very loud metal scratching sound coming from the hard drive. I have had hard drives pass S.M.A.R.T. tests that sound like a car is dragging a metal body panel behind it.

Possible cause:

  • Shock to your hard drive. Did you or a mail service drop it or accidently hit the drive on something? This could cause the drive to degrade rapidly.

Check:

  • Check for programs making frequent read/write requests to the disk in activity monitor. Make sure no unwanted programs are tying up your disk in the background.
  • If activity monitor looks OK, check how long it takes to transfer a large file to the disk. It should be close to the drive's advertised write speed (this may be affected by how the drive is connected i.e. USB 3.0 versus SATA).

If your disk is unable to write close to its advertised speed (or the maximum speed of the connection type) with few interruptions from other programs, it may just be faulty or damaged.

Update:
Just came across this possible solution

  • I found some new symptoms ! please see the Edit on the top of the question – user1062760 Dec 5 '16 at 17:10
  • @user1062760 This sounds like the behavior of a "green" hard drive. The RPM slows down when the HDD is not being used, thus taking longer to spin up and access files. Is it a Barracuda LP or green drive? This however doesn't sound like the full answer to some of the problems described. – Craig Dec 10 '16 at 0:38
  • @user1062760 I am not too knowledgable with the software side, but I would try some basic tools like [CCleaner] 1 – Craig Dec 10 '16 at 0:47
  • Well that didn't work. Here is the link to CCleaner: link. Also try out the tools on link. TDSSKiller, rkill, and adwcleaner have helped clean up my computer for free. If this is a virus of some sort, maybe this will help. – Craig Dec 10 '16 at 0:50
  • So after multiple similar tests I can gurantee that its somehow related with drive being idle. leaving it idle goes to dirt speed of 20KBps but a system restart immediately restores it to 50MBps or more. checking the windows power settings says shut down harddisk after 20 min of inactivity, is that the reason? – user1062760 Dec 18 '16 at 1:27

I had a similar experience with 1Tb Western Digital drive.

Turned out it was a defective drive.

Suggest 1. testing that adequate power supply is available for this drive. 2. check that corrrect PM and ACPI drivers are loaded (my experience is with Lenovo, and they are quite famous for providing bad drivers) 3. if possible replace drive with another one as a test.

Windows 10 seems to have some serious driver issues with SSDs, from my limited experience. Windows 7 seemed quite hunky-dory and happy with having one swapped in (did that about a year ago for someone who was very happy with it.)

I just helped a kid replace a drive on Windows 10 and it kept going to 100% disk use (reported; and it would become unresponsive/hung) with no (or very little) actual disk use, a search found many instances of the same problem, and various "solutions" (many of which did not work for us.) In this particular case, what worked for us eventually was setting the drive mode (which started out as "RAID" - kinda odd for a 1-disk-space laptop) and also failed for us as AHCI back to IDE.

This requires a trip into safe mode each time you change the drive setting.

There's a Microsoft forum post claiming that changing the interrupt setting fixes the problem, but it did not work for us...likewise someone claimed that going from RAID to AHCI worked for them. So what will work for you, I don't know - I just report what appears to have finally worked for us.

I should note that this problem did not "wait a month" - we could not get get the initial windows 10 updates to load because the computer kept hanging (original disk died, no backup, reinstall 7 from CD and re-upgrade to 10)

  • Umm My SSD is fine , HDD is the one that's pain – user1062760 Dec 5 '16 at 17:11
  • That was not at all clear. – Ecnerwal Dec 5 '16 at 21:20

I tried to disable some window service like bellow. My HDD performance 100% go down arround 10%

net.exe stop "Windows search"
net.exe stop superfetch
sc config "DiagTrack" start= disabled
sc stop "DiagTrack"
  • Just so I understand correctly - is your HDD performance improving or getting worse from disabling diagtrack? and it looks like a telemetry service so where/how you found it might be helpful, since it shouldn't impact performance that much – Journeyman Geek Apr 14 '18 at 7:26
  • Run these command will prevent HDD too busy by these services (100% active) . when the HDD is not busy it will run other application faster. "My HDD performance 100%" => it mean HDD run too much. it's so busy to run needed application – Lê Tuấn Apr 17 '18 at 8:33

Even though the post is a bit older I thought id share my experience for future readers: I had a somehwat similar experience with a 3TB Seagate Harddrive that suddenly operated excruciatingly slow. That also showed in the TaskManager, the hard drive was always at 100% utilisation.

I tried setting the MSISupported Key and changing the Harddrives from ACHI to IDE as suggested by Ecnerwal, but that did not help.

I then checked the services and processes again, sorting by drive utilisation, and found the Oracle RDBMS kernel executable among the top processes with about 10% usage (its always hard to tell which drive is used, since I got 3 in the computer and TaskManager wont tell you which one is used). After killing that the usage of the "bad" drive went down to 0% again. I have no idea what oracle's executable was doing there, but it did the trick.

So I recommend checking your process list and getting rid of this and that before you start messing with the Registry or the BIOS like I did (the latter screwed up my boot order and PC would not boot, got a bit scared there but managed to fix it), sometimes the solution can also be simple ;)
