Fixing Corrupted SD Card

Hi,

When my SD card is in my Samsung Galaxy S2 (Android) the phone appears to boot up and then reboots when it comes to a certain point.

I have tried a different SD card or booting up without a card and the phone completes the bootup sequence.

But I would like to get my original SD card working since it has application data on it.

When I connect the SD card to a PC using a USB adapter - I can see the files fine but had to rename about four corrupted directory names.

How can I have my SD card repaired for the phone to use?

I moved the contents of the SD card to a temp directory on the SD card and put in the phone.  The reboot loop has now stopped.  I then moved what appeared to be important directories back out into the root directory and used an android file manager to delete the temp directory.  Seems fine now.

You generally can't "Repair" SD cards once they are defective. You can try recovering data and copying elsewhere, but that is about it. You could try formatting the card, but I wouldn't trust the card even if it works after that.

I'm not sure if the problem is with the card or an interruption in the write process from the phone.

If I copy the data using a PC - to another SD card - I'm not sure what that will achieve because I may take problematic files with it.

I found the solution by trying a couple of things that weren't suggested.
