Simply botch ....

Have the USB flash drive (after the first anger was gone) checked again:

The stick is recognized after plugging it, the data can tw. read, tw. an error message appears.
Makes me suspicious that the stick as a "read-only" is specified.
Delete, format, partition or remove what is not possible whatsoever.
Have this checked on different machines and different operating systems.

On the web many possible reasons to be mentioned, among others:
* Permissions under NTFS (definitely was not the case with me)
* The stick has internal write protection contact which is provided on the board. (This has somehow contact, in metal enclosure quite possible)
* There are many built-in memory cells is defective, so that the controller for safety's sake to "read only" is to limit data loss.

I now do not know if and what reason is true with me. It is ultimately matter.
The fact is that I have a stick, can be read on the sensitive data.
I can not use or remove it and send it back.

Amazon itself has shown very accommodating and therefore their duty more than fulfilled.
Too bad it's my time, I've consumed with troubleshooting and the preparation of this review.
But if I can warn other customers before buying this product, has made this all makes sense.

So long ....

I for myself have flattened the stick with the clamp and it has been a satisfaction :-)

Have this USB stick purchased in the offer, because it pleased me well.

When I then wanted to use it, that store data on it, I had to quickly realize that nothing is.
Copying got stuck several times, the whole computer seemed slowed.
Today I wanted to call some data again, but, oh Graus, even when plugging the computer is frozen.
After a few minutes the mouse has had to move again, but no access was possible.
Now, this data is not so important, gave the stick therefore no second chance.

A USB flash drive to store data and back out again. If that does not work properly, as here, the good looks also saves nothing
For all those for whom their data are important, this is the wrong choice.
