Hi Aram, and all flexers....
There is one other interesting thing to consider. Many people, especially
users of p&s & bridge cameras, use the "erase all" function to clear their
images. Much better to use "format", as if "erase all" is used enough times
without formatting a card, it can cause problems with the file system, and you
lose your precious shots. Unfortunately, in many cameras, the format function
is hidden well down in the menus. :-(

Interesting. I have always had a sweet spot in my heart for
DOS. Once learned, it was pretty powerful and fast way to manage files and
the system.
At any rate, I never delete anything from my card on the computer.
Import all and then when I know things are backed up, format the card in the
camera. Never a problem that way.

Subject: [LRflex] SD card management, cute dogs,
though
Good day
All,
I just stumbled over this video the other day: https://youtu.be/cPdQVWP5pRs
And I watched it to see the dogs
action, it was however a bit dull but nice dogs, comparable to
mine.
The photog seems to discover that using a computer to
add/delete/mod the images created by a camera will lead to an
error.
Of course,
it comes as no surprise to you, from your own experience,
probably.
But the fundamental beneath that is that a camera does
not implements the complete file system management as a computer does. And
more
to the point, the file management is closer to Microsoft DOS than any UNIX
system.
First
because now MS DOS has fell in the public domain, second because it is is much
easier to implement than the recent file system such as 'ext4' or 'ntfs'. Both
are typically built for networking.
Back to the cameras, one must think that it is a tiny
processorthat does the input/output of the files (tiny but probably 10 or 20
times beefer than the Intel 80386 we had in the 90ies). The processor has been
optimised to write/read large sequences of bytes in a row (a 17Mbytes in raw
images for instance).
Of course if the SD support starts to contaiin 'deleted'
files put in .trsh folder with a .lost+found directory as it might happen on a
Apple Mac (it is a UNIX Under), the camera looses its paddles and bugs out.
Normal behavior.
So, best practice, download all images on
the computer and edit them on the computer. Or use the file management of the
camera to delete them before downloading. But never mix both practice or else,
you may loose your precious work!
It was the tech minute of the
week, enough, back to Imaging
:)
