How to understand what spoils photos in linux?

Question

linux

There is a certain sequence of actions for processing photos. In most cases everything works fine, but sometimes something is buggy. And I can't imagine what it could be and how to fight.
Here's what I do:
1. I take some photos.
2. I upload photos from the camera using a computer with ubuntu 10.04 to a mounted network folder on the second computer.
3. On the third computer with windows xp these photos are cropped in gimp.
3.5: Something strange is already happening here. Thumbnails of processed photos in nautilus are not displayed correctly. They are not at all what they are in reality. And if you open them from the first computer, it turns out that the picture is damaged. From other computers everything opens correctly.
4. Then, on the first computer, run mogrify -resize x700 -quality 65 -sharpen 15 *jpg
As a result, we get corrupted pictures like this:

Ie . mogrify tries to work with some cached version of the photo. Why is this happening? How to fix?

Answer 1

I would start with a system test - smatrctl, memtest and fsck. Most often, according to the killed pictures, it turns out that the disk / fs or memory is pouring.
With three computers, of course, it's a little more difficult to localize.

Answer 2

Or maybe memory or storage is buggy?

Answer 3

Most likely, the photos are not loaded, I had this when I tried to open from a USB flash drive inserted into a network printer. I decided to change cifs to nfs.

Answer 4

I had the same thing, Fedora 17. Very rare, so I didn’t dig, but a few photos got messed up, yes. I haven't used mogrify, so that's not the issue. KDE.

Answer 5

You can't investigate anything here without running memtest86+ on all three computers (for the night).

Answer 6

If the photos were taken on a camera in which the software does not fall under the criteria of open source software , then perhaps they are spoiled by Virtual Richard Stallman
