I cleaned out my phone by deleting images which were on my memory card and have recently discovered that the N900 has been misbehaving. (see attached image) i get an image of a cracked photo instead to indicate something is wrong with the file. when i click on the broken image i get the message 'this image is not available'. so i cant even delete this file. i literally have a hundred of these icons which make their way between my normal gallery photos. today however i noticed these annoying icons disappeared. in their place were photos i had deleted a while back. on trying to re delete these the icons came back. so it looks like files have not been deleted properly from my memory card. i cannot see them anywhere except when they show up in the gallery. any ideas guys/girls on what i should do? i want to avoid formatting the memory card. thanks
