Hi,
I inserted a micro SD of 2 GB, and tried the following:
1) Only press power-up (nothing happened)
2) Press continuously power-up and connect to PC. The Pc detects the ADFU device
-No disk is detected.
-In order to validate (or not) your assumption that the device wants re-format, I went to disk manager in order to find the device. Note that if the device was detected as a disk, but no drive appeared on 'My computer' it may happen due to bad partitioning. I opened disk management but as you can see in the following picture the device is nowhere to be found. That means, that no partition software can do something on this device. If there is no disk, then you cannot create a partition.
I may try to find a linux computer to plug the device there to see if a disk may appear there, but I am pretty sure that nothing will appear.
I will try to check your suggestion too, just to eliminate also this option.
I am still open at any other suggestions or things to try.
Thankx m8.
