I have a P6200, no root and using stock recovery as of this writing.
I had a P6210 and I was able to fix External SD Card writing on it manually.
I tried the .zip in this thread and it didn't work on my P6200.
I am thinking it didn't because my device is either rooted, or using stock recovery.
I will root and perhaps install CWM, and test further.
My test was using ES Explorer to create a new directory in the SD card. It couldn't, so I'm pretty sure the fix didn't work with my particular configuration.

Do you have some kind of file explorer installed? If so, please browse to /system/etc/permissions and view the "platform.xml" file. Scroll down to find the line with "WRITE_EXTERNAL_STORAGE". There should be two lines below that that start with "<group gid". One should have the string "media_rw" and the other "sdcard_rw". If so, then the fix DID apply properly.
"root" shouldn't matter for this...
Wait... how can you get into /system/etc/permissions if you haven't rooted the device? I was of the impression that you can only access that directory if you are rooted. I certainly can't get there.
I was able to on my P6210 when it was rooted.
