SD Card Read Only? Can't Write to it? In Properties, there's No Security Tab to Change the Card Reader Permissions? Try THIS.

Question

WINDOWS 7 AND WINDOWS 10

YOU CAN THANK ME LATER ! - The Solution is hidden within gpedit.msc

After sifting through all the frankly useless 'help' out there ( e.g. unlock the write protect tab etc, change the registry keys etc...), it's simply a restrictive setting within Windows 7 or Windows 10.

Thank you to ****/blog/enable-or-disable-folder-options-in-windows/ for sending me in the right direction.

Run gpedit.msc

Windows 10 try the following: - User Configuration > Administrative Templates > Windows Components > File Explorer

Windows 7 try this: - User Configuration > Administrative Templates > Windows Components > Windows Explorer

I tweaked the settings within "Remove Security Tab" and "Prevent Access to Drives from My Computer" and then BOOM - disk write permissions returned to my SDHC Card in the Card Reader Drive, H:

Also check in Computer Configuration > Administrative Templates > System > Removable Storage Access > Setting: Removable Disks Deny Write Access (select Disabled)

Answer 1

Some SD cards have a physical switch that controls write access. The switch is very tiny and hard to find.
