Pulling my hair out over a micro SD

Have you tried a different card reader or adapter if you are using a micro
card?
I have a slot in my laptop that doesn't work. I narrowed it down to the
reader. It is giving code 10, which means the device is bad.
Also, I experienced that some micro to disk adapters tend to fail sometimes.
Finally, keep in mind that this is 16GB. Those I believe are the latest on
the market. I would not be surprised at all if it went bad on you.

Hi
Thanks, to you both.
The original fs was fat32 not ntfs. All attempts in windows to format fail,
hense reading forums and learning of the HP tool which also fails.
Micro SD's don't have a tab. If it did I wouldn't be able to touch and
delete a file.

four kinds of freedom, for the users of the software:
* The freedom to run the program, for any purpose (freedom 0).
* The freedom to study how the program works, and adapt it to your
needs (freedom 1). Access to the source code is a precondition for this.
* The freedom to redistribute copies so you can help your neighbor
(freedom 2).
* The freedom to improve the program, and release your improvements
to the public, so that the whole community benefits (freedom 3). Access
to the source code is a precondition for this.
