Destrojed JPG picture (not from Affinity)

If you are having trouble with the output from a DOS command, then you can direct its output into a trxt file, for example:

CHKDSK > chkdskoutput.txt

A problem might be that you don't always know where the text file is being wriitten. I would recommend using a full path, for example:

CHKDSK > T:\chkdskoutput.txt

Where T: is my Temp directory. Or you could try %Temp%.

a DOS text box appeared for a fraction of a second and dissapeared. It happened with both commands (AFC and CHKDSK). No report, no prompt that it was working or stopped working. Just nothing. I can try something else when she comes back home about 6 PM and it is 8:30 AM now.

That's not expected. With either of those commands, the DOS box remains open until you close it so you can see the results.

Does the DOS box close as soon as you type the command? 

What happens if you type a simple command like 'dir'? Does it complete with the window remaining open?

I tried, also, MalwareBytes. It found some malware and removed them, but the photos are still the same.

The photos seem to be damaged on the drive already (as opposed to being OK but displaying improperly on that system). If this the case removing the malware or virus won't fix the issue.

I installed "Stellar Repair for Photo", too, but it didn't help. I was watching, in a separate window, the folder with the pictures while it was running and nothing happened when it said that a picture was repaired.

If the photos are damaged on disk a program like this is, to the best of my knowledge, your only hope. You might try different programs to see if you get better results. 

It sounds like you're running the program against an entire directory at once. You might want to try a single photo in each of several programs to see which works best (I'm assuming that all the photos were damages at once and thus in the same way).

One picture or all, it doesn't matter. The program doesn't allow to see pictures immediatelly after repairing and ask for a serial at the end.

I started with SFC /SCANNOW but no window is opened to monitor the progress. It is the same case with CHKDSK. Is it OK or something is wrong?

Where are you typing the command, Petar? When you choose ‘Command Prompt > Run as administrator’, a window should open and display a command prompt (‘C:\>’ or similar) where you type the command, and that window should remain open until you close it.

And for either, the DOS cmd window or Microsoft PowerShell, you can increase their scroll-textbuffer (under settings) to some higher numbers (1000 or what ever) in order to have enough buffersize for scrolling back on their windows and see every printed output.

I was right-clicking on "Start" button and choose "Run". There was no option like "Run as administrator". But now, after your post I found the "Command Prompt" and "Run as administrator" and I will try it after 6 PM when my wife comes back from work.
Thanks Alfred.

Good question - I wish I would have asked that earlier.

I finally found out how to switch to DOS and run those commands. Thank you @casterle and @Alfred.

Well, Petar, you could post one of those JPEGs here … I mean, one of the less personal ones … for review. I have seen similar artefacts on the Mac when Apple’s Preview App was overwhelmed with very large files. I would suspect it could also be a RAM or graphic cards issue.

You're welcome. Keep us posted if you need more help.

Once upon a time, in DOS era I was a guru for DOS (and programming in BASIC). But now, as time passes by...

He's posted one earlier in the thread (not the screenshot in the OP). I downloaded it and it of course it displays improperly on my system. I opened it in JpgFix (free oldie) but it found no errors in the file.

The program is quite technical - someone who understands jpeg internals might be able to salvage the more important images with it. At least some of the damaged images display properly in bands, so there are chunks of good data in them - perhaps repair is possible.

Me too. I wrote DOS-based software (and 805x firmware) to control telephony hardware for several years. Things were simpler then!

If graphic card is an issue, wouldn't it affect on everything it is shown on the screen?

How can RAM be a problem? I don't see the connection.

This doesn't sound like a hardware problem to me, but it is possible. Corrupted RAM, whether CPU or GPU, can manifest itself like this, but IMHO it is nearly impossible that this would occur without other symptoms. 

[Petar Petrenko]

I checked the computer with SFC and CHKDSK and there were no problems at all.

And how RAM, CPU, GPU or else can be problem if it only happens on pictures? Everything else works OK.

Firstly make sure you have a reliable external drive.

Have you looked at Volume Shadow Copies?

Also there may be a versions tab when you right-click on the image and there may be a version intact.
