I have one SD 4Gb. When i try to read this in pc3 flash, it read only 2gb. The chip memory is MT29F16G08MAA, i don't know the controller because is covered. When i try to recover files, with Block Number Type1 i see the root, folders and files, but the files are corrupt. I need help!! Regards! |

Most cases in wrong size, maybe caused in bad controller! I am confused about you said it covered , and how do you use block number function? |

I there is two, disregard from this post. You can't read more than 2GB because the chip size is only 2 GB. Is it a no-name SD? I think it is a fake card. Treat the chip as a 2 GB card as it is and try to recover it. When you do the high level recovery, be aware of the partition size which also most probably is wrong! |
