Hi my friend,
Try to format it in a PC using a software for it.
You can use the software which you can download clicking
here.
Then do followings:
- Plug your memory card in the PC.
- Run the "HPUSBFW_2.2.3_MASTER.exe" file that you downloaded.
- Select device as your memory card.
- Select file system as FAT32,
- Write a volume label.
- Confirm that the quick format option unchecked. (And also the other options will be unchecked.)
- Click start button to format.
That's all.
Hope this helps.
