I can't solve this error

The disks are genuine. I checked the QR code on them

The Raid 1 keep getting degraded. Then I reset disks to non-raid do a full check with chkdsk /f /r /x

0 Errors found

Then I do byte comparison of each file in each disk and they are exactly identical

But Raid 1 is kept getting degraded

How can I debug this issue?

Here my disks and drivers

I am using Windows 10

@Swiss3003 thanks

I changed both ports and cables (brand new). testing again right now

Only DST left

what are CRC errors meaning?

Also which controller card you would suggest me as raid 1?

@Swiss3003 thank you so much for answers

I did the DST tests and no errors shown. So what do you think? By the way currently I am on new cable and new port. Haven't tested Raid 1 yet

Thank you @Swiss3003 but the disks are still not working properly. Sometimes they just freeze too long

I plan to purchase this raid card and test it what do you think?

Marvell® 88SE9230

look at this image not normal at all. it just 100% active no read or write

image

and here my another sata 3 reguler hdd drive

the other hdd immediately starts read write as supposed to be

@FurkanGozukara ,
You seems to have a SW RAID 1. So it might be a good idea to look into this issue from RAID initiator perspective. After all the RAID logic is taking the decision of degrading the volume.
There must be a trigger for that. If we can find that trigger then we should be able to narrow down our search.
I might have started looking at the "Computer Management" -> "Event Viewer"
Capture1
We need to look for the event for volume degradation. Once you find that then look for the Drive Events just before that. For both cases look at the event description to have a better understanding.

@DebabrataSTX thank you so much

currently disks are non-raid but speed is terrible for some reason and i can't find. normally I use intel raid manager to make my raid 1

I changed cables as @Swiss3003 said

I have another HDD in same area in their previous slot working perfectly fine. this is also eliminating many other listings @Swiss3003 made

interestingly i did another test today and results are different than before

still very slow compared to what it should have been but didn't wait forever (10s of minutes) to start reading writing like before

I made this change recently

disk K is ST4000NM0024-1HT178
disk U and D are ST8000NM000A-2KE101

@Swiss3003 thank you so much for reply

They have been idle all the time since i opened this thread

But I didn't remove cable

I just did a test and still slow but at least directly starts working

image

Also intel raid manager is displaying 6 GBs . so i think sata 3?

image

Also what technique do you suggest to erase disks? self-clean

the disks are so new but i want to give it a try

@FurkanGozukara ,
Just to add, you can download SeaChest_Erase from https://www.seagate.com/content/dam/seagate/migrated-assets/old-support-files/seachest/SeaChestUtilities.zip

Can you summarize exactly what operation/functions you want to do with the drive. That way it will be easy for me to send the right command(s).

An erase on the drive would self-clean all the LBA's and set the drive back to factory and clean all the glist and plist on the drive. returning the drive to a health state.

I want to do what @Swiss3003 said

Thanks started it lets see what happens
