First of all, WELCOME to TDF. Please go through this boring, long but useful thread. In future, PLEASE USE A PROPER THREAD HEADING and be specific with whatever you want to ask or say.

though recuva is a great utility to recover data from deleted/formatted disks, it's not the ULTIMATE! There's a possibility that it wasn't able to recover all the data from the formatted sectors and that's why some of your PDF files won't work. This happens a lot with images and other media files. AFAIK, the popup appears when your computer isn't able to access your memory card (either it has gone kaput, or it's password protected, or your card reader isn't able to connect properly-happens a lot with cheap card readers)
