No i dont try SFC. But it working fine with GPT partition now. So why it get corrupted with MBR then? So why it not worked well with MBR then ?

Ah and i forget. Almost everytime when i was clicking run 3dmark11.exe test, my system become unresponsible and laggish. I cant do almost everything. I cant restart system because START button stop working.
Opening some file taking 10 second. I must force hard reset to work properly again system. Almost everytime
when i was clicking run test in 3dmark 11 causing this issue. After long wait i was ablee to check usage of cpu ,ram and disk, and was 0%.
So where was the problem? Software , my disk or ram?

But after format is ok.

Data corruption doesn't come and go every few weeks or so.
in my experience, when some data fails to read on one day, and then the next day it is read fine, it is 99% likely to be the ssd.
You do realize you are advising someone to RMA a perfectly good drive, don't you?
How else would you diagnose this issue ?

So rma SSD and say what? If on GPT partition and new install of Windows 10 is fine.

Also smart is reading all fine. What you think ?

many ssds slow down overtime, and 'gets fixed' and appears perfectly normal when formated or data refreshed, ... i have no idea what to say when RMA.

maybe wait few months and see if the issues re-occur after the same time span as the 1st issue happened ?

how old is the ssd ? how long did it take for errors to show up after the last windows install ?

What makes you so sure any data failed to read properly? You have had no contact with the OP's system, have seen no error report, no diagnosis whatsoever except for the SMART parameters list which indicates the disk is healthy. Is that what your experience is based on?

All we have so far is the OP telling us his system stopped malfunctioning after a new OS install. Before I were to think about disk failure, I would seriously consider software issues (faulty drivers for example) and/or other hardware issues that lead to silent data corruption - since the SSD error corruption mechanisms picked up no error even though the OS was seriously crippled.

Also, why do you keep mentioning SSDs slowing down? Did you experience data corruption on your SSDs or just slow read/write speeds?

So what you think? That issue with system slowdown when i was clicking 3dmark 11 was caused by ssd or software?

Tough to say. Could be a driver issue. Could be a power supply issue. Could be a SATA cable that has a microscopic fault. Could be an ants crawling across your motherboard on the way toward that bowl of ice cream. If you've ruled out memory and reinstalled the OS and have it working fine going forward and the problem does not come back, it's clearly a software issue or so it seems.

Even if i try to RMA my SSD , they check SMART STATUS on disk and they tell me that SDD is ok and they dont accept RMA. Still on GPT partition all is fine now. Problem with corrupted Windows 10 was when i was on MBR . I dont know what to think now.

both (slow down + corruption) on both M4 SSDs.

i experienced similar bahvior to what the OP is describing, sometimes windows fail to load, sometimes it loads fine, and sometimes it is very slow to load.

this also applies to many applications, not just loading windows, but loading windows is where most issues are most noticable.

in my case i ALWAYS fix it with taking backup image, and then restoring it, without clean install.

This rules out hardware/software issues, because the same os installation works on the same hardware with no issues after doing the data refresh.

You said:"This rules out hardware/software issues, because the same os installation works on the same hardware with no issues after doing the data refresh." So what you mean? It software or hardware fault ( ssd )?

And yes in my situation os now working fine with my hardware this time on GPT partition after format. Thx for reply.

Try to rma ssd or they dont accept rma?

i meant that no other hardware/software are the issue, only the ssd.

also, please answer this question:

SSD is 2-3 month. And it get corrupted month after 1 month after install of Windows 10. But all smarts of ssd telling that ssd is fine.

What you think?

But somebody said to me this:
"One of GPT's features is better reliability for its partition info: "On an MBR disk, the partitioning and boot data is stored in one place. If this data is overwritten or corrupted, you’re in trouble. In contrast, GPT stores multiple copies of this data across the disk, so it’s much more robust and can recover if the data is correupted. GPT also stores cyclic redundancy check (CRC) values to check that its data is intact — if the data is corrupted, GPT can notice the problem and attempt to recover the damaged data from another location on the disk. MBR had no way of knowing if its data was corrupted — you’d only see there was a problem when the boot process failed or your drive’s partitions vanished.
If your Samsung Evo 250 GB drives need refreshing or formatting that often, it's time for new SSDs that don't have that problem.

" "



So maybe it is something with my SSD if it get corrupted on MBR partition and needs refreshing? Like i said on GPT partition all is fine.





This:" — if the data is corrupted, GPT can notice the problem and attempt to recover the
damaged data from another location on the disk. MBR had no way of knowing if its data was corrupted

So, how would MBR get corrupted, and not GPT?
This isn't like a HD, where the sectors won't relocate (unless it has bad blocks), so, every time you write something to the SSD, you are accessing different cell locations on the NAND.

Something must be going on to be causing issues.
Do this, create a 1GB archive of whatever files, and use winrar or 7zip, and copy that a few times on the SSD. When that is done, run a archive check, and see if anything is corrupted.
If it is corrupted, it is either the SSD acting up, or one of the other things I mentioned above that you didn't try.
