The camera scheme is a standard. "DCIM" is not random.

https://en.wikipedia.org/wiki/Design...ra_File_system

"The filesystem in a digital camera contains a DCIM
*(Digital Camera IMages)* directory, which can contain
multiple subdirectories with names such as "123ABCDE"
that consist of a unique directory number (in the range
100…999) and five alphanumeric characters, which may be
freely chosen and often refer to a camera maker."

See if you can use the in-camera SD format capability. It
should put a fresh filesystem and place a DCIM at the
top level.

There have been cases, where Windows computer meddling with
an SD, results in the SD becoming useless, as the camera
won't fix it. There are some corner cases where this
simple scheme falls apart. It does not pay to "edit"
the media from the Windows side.

To reformat, you'll probably need to pull the USB cable,
request the camera to shut down or something, to get the
current operation to stop. USB Mass Storage, only one entity
can be Master, so if the PC runs the camera memory, the
camera cannot run it. Once the umbilical is disconnected,
and the camera is back in charge of the SD, it should
be able to format it the way a camera needs it.

Now you'll know the next time, to not screw around.

I'll tell you how I use mine. I have a 32G SD in the camera.
I use flash cells like toilet paper (sequentially). The camera
just keeps creating new folders, per session. I have no plan
to "clean it" or use in-camera format, until the entire 32GB
is used. Which is probably the year 2050 or so. I don't practice
a special ceremony on the SD, put it on an alter with an animal
sacrifice. I just use it until it's full, which hasn't happened
yet. That way, even if the wear leveling isn't all that good,
the wear is actually spread out by the application of the thing.
That's why I do it that way.

I run my flash-based telephone answering machine the same way,
use the flash sequentially, only blow away all the calls when
it's nearly full.
