Then by the magazine ct (H) the h2testw tool used. This describes a disk full and then makes a reading test (verify).
When writing for about 3 gigabytes, flying the stick out of the system, it is quasi unmounted. The tool then aborts also. It takes a few seconds then the drive is reached again. Further tests also cancel unexpectedly.
The second test was then directly in USB3 port of Surfaces. Same Mistake.
Third Test at a workstation, re-USB3 port, write to about 10GB, stick flies out of the system.
Fourth Test at a USB2 port: successful! Stick can be 100% reading and writing.
Stick was claimed by me and sent back, today came to the replacement drive.
This shows the same problems.
So I myself have no confidence in the new model DT101G3 and will let it first with the brand Kingston.
Very very bad, he looks good, is small and cheap.
Tested 2 sticks at each 2 PCs, flawed: Conclusion. Although there is no scientific test series / rate but for me that arrived.
But that was unfortunately nothing :(
