Ok, so I have a 4gb sdhc card that I'm using for my R4i sdhc... When I try to copy files onto it I get "Cannot copy 'FILE': The file directory is corrupted and unreadable." So I removed all my files and tried to format it and got "You do not have significant rights to preform this operation." Any help?
Try a different MicroSD adapter, and check your adapter for any Lock switches that might be on. Try this formatting program. http://www.sdcard.org/consumers/formatter/
It's not the adapter, I've tried 3. I'll try that program and see if it does it. Thanks for the reply EDIT: Thanks, it's working properly now.
