Files hash get changed

[JekylHyde]

Hi
i have a strange problem.
i have a ssd hard drive.
the problem is that my files hash get change for some reason.
i found out about that by watching my video files & here & there i saw some visual error.
i checked the hash & compared it to the hash of this file that i had on a backup - & it was changed! the file on the backup didn't got this visual error...
why a lot of my files got this problem?
i tried checking my hard drive with chkdsk & with "Data Lifeguard Diagnostic for Windows" but no errors found on the drive.

Is you SSD a Samsung brand SSD? If so, what model specifically? Maybe can post a pic or link to that drive model.

Sounds like a silent data corruption.
Perhaps you could check if issue happens with another SSD drive, just to be sure it is with SSD drive and not with storage controller in your PC (or maybe buggy controller drivers)?
I had similar issue around 10 years ago and i've found out it was caused by buggy windows drivers for ICH10R controller.

I did had the same issue once with "cheap" and crappy chinese flash pen drive ... Sollution was to toss it to the garbage.

Try with another drive, if possible a standard drive - not flash/ssd and if you don't see the problem again you can confirm that the issue was with the ssd.

If you do have the same problem even with stnadard drive then the problem is with the system/computer doing the corruption while moving the data to the drive.

Also did you check if the hash was correct when you saved the file to the drive ? If so and if the drive changed over time even if you didn't change the file the problem is with SSD loosing the caacity to hold your data intact ...
