Hello everyone! Does anybody know how to fix the unknown error (-23) on IPad 2? It is running on IOS 4.3.3 and I really don't have any idea about that error. It's just new and all. I only have it for a week by now. It says "Attempting to copy to the disk "iPad 2 WiFi" failed. An unknown error occurred (-23). The photos on my selected folder won't show up on my iPad. Actually, it doesn't show any pictures at all. Some of my books won't show up in iBooks either. The music was okay though. Oh no. I tried it again just now and it doesn't say "Attempting to copy to the disk "iPad 2 WiFi" failed. An unknown error occurred (-23) anymore. It says now The iPad "iPad 2 WiFi" cannot be synced An unknown error occurred (-23). Please I really need your help guys. By the way, I'm also new to this ipadforum.net and I don't know if I posted on the right forum (Sorry for that) but your help would be so much appreciated. THANKS A LOT.
