a problem. On the other hand, compare the cost of disks to the
value of your files. 1 TB SSD's run about $65 USD. A 2 TB disk
is about $60.<br>

"validate jpg files" revealed several candidates, but they seem
intended for programmer/geek people. For example, the JPG data
begin with FFD8 hex and end with FFD9. So all you need do is
find or write a program to test for those values. And sure
enough, people have done that, if you can figure out how to
build/install on unix/linux.<br>
Maybe this repair site will help: <a moz-do-not-send="true"

I have not tried it.<br>

using FreefileSync each time I import new raw files. It includes a

space used, so today I'm relying on the network trashbin plus a
regular backup on an another disk.
<br>
But clearly not enough 🙁
<br>
<br>
What could help is to be able to validate the integrity of the
collections and/or the backup. So if any idea is welcome

Off on a tangent...
<br>
If your backup procedure can overwrite older backups, you need
to use a better backup.

I, too, am a victim of Windows.
<br>
I use Macrium Reflect ($69 USD).
<br>
I don't know how to make it overwrite earlier backups. It's
probably impossible.
