How to change SD card permissions

[hinderbrus]

Hello

Is there any program that can change permissions of the internal/external sd card?
I am a rooted user with root explorer and can change the permissions of all other files except the ones of the two storage cards...

Anyone has a clue about this?

tnx

If you're talking about /sdcard/, the reason is that the permission mechanism in linux/android is implemented by the filesystem. The /sdcard/ filesystem is a windows filesystem (FAT or NTFS, I think FAT). This filesystem does not support UNIX-style permissions like the other filesystems on your phone (ext2/3/4, squashfs,...).

I am having a problem where suddenly none of the Apps on my phone can write to the SD card, what is the solution for the permissions problem? I can read from it ok and both read and write when it is in my computer.

Did you sort this? I'm having a similar issue, can't write to my SD card..

I get this error message when I try to change permissions: "sdcard permissions cannot be changed because the file system is read-only."

All good. Re-formatted my SD card (FAT32).. fixed the problem.
