I have a micro sd card which can't be formatted in Disk Manager or in Diskpart, i always get a message saying that windows could not compelete the formatt.
I thought I solved it by following a guide that said to go in to Disk Manager, right click on the disk and remove its "name"/"location" (or what it's called F:.) and then add it again, and lastly format it. It seemed to work as it formatted completely, and I was able to put files into the SD card and opening the files from it.
However I decided to remove the card and then put it back in my computer to see if everything was working and found that the SD card suddenly was Unformatted. I can't open it or reformat it exept for with the above described method.
I have no knowledge of if the card currently has NTFS or FAT or something else.
How can I format this memorycard?
Any ideas are welcome! :)
