A few days ago, I experimented some strange issues with my Windows Phone device. After lose some data, I decided to perform a hard reset of the device. Previously, I extracted the micro-SD card and copied all its contents to my PC's hard disk. Aparently there was no problem with this copy.
Once loaded on the computer, I tried to erase some folders from the card but it wasn't possible. The card seemed to be readonly protected.
I tried to manipulate the card in a Windows 10 system, in a Windows 7 and in Lubuntu 14.04, using diferent adaptors, USB, standard SD...: in all systems the card was shown as readonly filesystem. Neither Linux's gparted nor Windows' diskpart were able to change this condition.
Despite has been related with a previous question, the difference is that I'm sure is not concerned by a mechanical switch. As I said, I tried to modify this micro SD card in 3 different devices, a PC (dual boot with Linux and Windows10), a laptop (with Windows7) and a Lumia Windows Phone (ver.8.1). To connect the card with the computers I used one SD/MicroSD adapter and two differents USB/MicroSD adapters (with no write protection switch). Both computers displayed messages about a readonly protected filesystem and the smartphone was not capable of install any app or move no multimedia file to the folders in the card.
Any idea of how proceed with this without reformating the card? It is possible the card is fatally damaged or it could be only a problem of corrupted data?
The card is a Lexar 128Gb SDXC, exFAT formatted.
