New hard disk running very slow 1mb/s

[klokklok]

For some reason my hard disk is running very slowly on my pc and sometimes not even reaching above the 1mb/s while copying.

PC Specs:
HDD: Seagate Barracuda 7200.14 - 1TB
SSD: Samsung SSD 840 EVO 250GB
CPU: Intel Core I7 6700k
GPU: Gigabyte GeForce GTX 1070 G1 Gaming
MOBO: MSI Z170A GAMING PRO CARBON
PSU: XFX XTR Series - 650W
OS: Windows 10 64 bit

Screenshot from my hard disk in my Disk Management window:

I have installed the right drivers and set the hard drive up with software from Seagate. Also switching the sata cables and changing the sata slot didn't help. After this I decided to send my hard disk back to the store to get a replacement. This replacement has exactly the same problem its just running way too slow.

I have tried it on another windows 10 64 bit pc today. The hard disk runs fine on that pc with the same sata cable (100mb/s+ copy speed to the SSD). So the hard disk isn't broken.

I'm wondering if someone has any ideas how I can solve this problem so my hard disk will run fine like it should do!

Welcome to the community, @klokklok!

I'd strongly recommend checking your connections to the power supply unit and also try using a different hard drive in your PC to see what its performance would be. You have done a pretty good job with the troubleshooting so far, but I'd also recommend you check if you have installed the latest BIOS version for your motherboard. You can do that through their official website. In the meantime, another thing you could try is resetting BIOS . This will get your settings back to factory defaults, so you will need to re-configure all manual changes in the BIOS.

Give these a try and let me know how it goes. Good luck!

I'm going to switch the psu cable later today and put it in another slot. I forgot to say I flashed my bios to the newest version. Also I didn't change alot of settings in my bios except a small CPU overclock.

Do you think trying another hard disk is really going to help? (I Don't have one) because my SSD runs fine.

If you don't have a spare drive, you don't have to try this method. I'm just suspecting shortage of power supply to the secondary drive. If you have any important data on that drive, back it up elsewhere before proceeding with the troubleshooting, though. Indeed, give another Molex cable a try or better yet test your power supply unit altogether.

If the PSU is malfunctioning, you should definitely consider replacing it.

Keep me posted with the tests.

check the disk with crystaldiskinfo and seatools

firmware of the hdd up to date?

is it an M.2 SSD or sata?
try sata slots 3 or 4,
not 5 or 6

I just switched to another sata power cable for my hard disk and I put it in another slot on the PSU. Sadly I'm still getting the slow overwrite speeds.

@helpstar I tried to check the harddisk with software from Seagate but it still didn't reach 0% after 1.5 hours. I used sata slot 4 and switched to sata slot 2 some days ago. I also setup the harddisk with software from Seagate and I updated to the latest firmware.

install intel update utility and try updating drivers (chipset,...)

run checkdisk on the hdd (right click in explorer on it, properties, tools, scan)

Couldn't find any new drivers for intel. I tried the checkdisk and it took ages to even fill up 1 pixel of a green bar so I decided to restart windows. After this the check only took 10 seconds and it repaired an error on my Hard Disk. It seems to run fine for now (100mb/s) copy speed but this happened before and after a while it jumps back to the low 1mb/s. I'll give an update later if this actually fixed the problem!

run memtest86+ booted from an usb flash drive

where did you plug in your SSD? Which SATA port?

This seems pretty odd, @klokklok!

Do you have a spare HDD lying around somewhere? I'd suggest you check it will perform with still the SSD + another drive in those SATA ports. Try also swapping the places of the HDD and the SSD to check if the system will boot up properly and how it will behave then.
