ok. im having issues with my card(16gb class4). I partitioned the card a while back, and i decided today to format it so i went to recovery and went to wipe, then wipe sd. it did its thing, then i did it again just in case but it froze. After a while i decided to remove the battery. i then booted the phone, once booted i went to sd storage and it said that there was no card mounted. i figured i screwed something up when i took of the battery mid format. so i went to recovery to try and mount the card but all it gives me is E:Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0) (Invalid argument) so to try and fix it i tried to format it on my computer. i tried 3 times with no luck. i tried different formats and nothing. of corse i tried fat32 first. i even tried deleting the partition and left it unformatted. Im gonna try my other card later and see if it detects those at least. Thanks for the help in advance.
