I have an exFAT SD card which runs great and serves excellently for my needs. But it is mounted as read-only in my Windows 7 computer. It reads and allows copying, but not the changes.
Actually, there are many cases like “this word document is read-only”, “the pen drive comes with read-only status”, and “the disk is write -protected” that will forbid any changes including modify it, erase it, append to it, move it. The main purpose of read-only is to control how you use the data.
When you receive the exFAT is mounted as read-only in Windows 7, to solve it, you can make use of Windows Diskpart.
Open CMD prompt, and type in the command as the following:
diskpart
list volume
selectvolume N (N refers the volume number of the read-only disk)
att vol clear readonly
Besides, you can run “chkdsk /” in cmd.exe or run the GUI based scan by right-clicking on the exFAT partitioned drive and selectingProperties-> Tools and running theScan disk tool. The exFAT partition needs the scan to be done to reset it back to read/write capable.
If your problem was not solved by those given suggestions, you can try to reformat the exFAT read only drive such as USB drive, SD card, pen drive, etc. And here, we will take an example of reformatting an exFAT SD card.
