    I was rooting and accidentally hit format and then had to buy a program over 100 to recover the memory...It shows up fine but like when I downloaded tibu nothing from the sd card popped up... Like none of my games were on there. Also I cannot get my pictures back.

    What was the program you used to recover the data on the card? It sounds like it didn't do anything.

    Greetings kench33,

    I don't know what program you used to recover you SD memory, but it's possible that the recovered files are not in proper Android folder structure.

    You might try dragging them to your computer, formatting the card, setting your phone back up the way you want, and then dragging the files back to the SD card and putting them where they belong.

    Handy recovery I've used several times to recovery sd data. 1.0 is a free version, which you can extract from ultimate boot cd ubcd4win.

    Luckily I have it here:

    I have always had success with Test Disk It is a more advanced recovery program. However for me it just plain works

    EDIT: Also note the more you read and write to the disk the less chance of recovery so keep things to a minimal.

    If you fully formatted the SD card, there's nothing to recover. (The files are gone forever.) If you quick formatted it, Test Disk has a companion program called PhotoRec PhotoRec - CGSecurity which will probably recover all your files. (They're both free. Test Disk is for recovering partitions after you repartition the card.)

    If you've overwritten a file you might be able to recover it, but the old data will be gone, so the recovery will be useless.

    not true there are unformat tools you can find anyone with access to a Win9x Norton Utilities can get the program. Its still fat and fat32 partitons for the SDCARD not like trying to unformat NTFS or EXT. You may need to Go DOS'ing to find one of the old unformats but they are out there. And very handy for current situations.

    Which will work if you quick formatted the card. If you fully formatted the card (wrote to every cell on the card) there's no old data to recover.

    An SD card isn't like a magnetic platter - there's not even any residual magnetism that could be recovered with a scanning electron microscope. If the cell is 1, it's 1. If it's 0, it's 0. To find out what it was before you rewrote it, the only tool that would work is a time machine.

    Fully formatting a FAT (16 or 32) drive means writing F6 to EVERY SINGLE CELL (in an SD card - every data location on a magnetic drive), overwriting ALL the old data. So, yes, you can "recover" - the NEW data. But that won't do you any good. (And you CAN format an SD card to rfs, NTFS or any other format you like. Even if there's no current formatting program to do it. A format program is one of the most trivial pieces of software to write.)

    I though Linux usually did a quick Format of DOS I am assuming Android would do the same. I can't say about SDCARDS My Knowledge of them is that either it works or it don't I do regular backups of my card so that moment that it don't work no biggie put a new one in and start again. My recovery experiance is left on the Hard Disk. It feels like I have Recovered The internet as much stuff as I have had to recover for Friends, Family, Fat and Psychopathic wives. However the reality of it is that I haven't come close to the vast number of data as the internet just feels like it :D

    I have "Accidently" Formated Fat drives within Linux and was able to us unformat to get it back. However the real lesson here is
    1. Always have a Backup
    2. Make sure of what your doing before you do it.
    Those two alone could have saved valuable time for me and a host of people I've had to get data back for.

    You can try a program called Recuva. Free download. I have used it several times to recover photos from camera SD cards and USB drives. Once written over though, it is basically useless.

    Recuva works ok I actually Like their CCleaner

    PhotoRec is my choice I think its a bit more powerful at recovery than the GUI's

    I used Photorec to get files off a borked SD card just this weekend. Well worth a try!

    Recuva recovers deleted files.

    Photorec looks for blocks of data that look like files and recovers them.

    If you completely overwrite the directory on a drive, Recuva is useless - there are no "files" to recover, there are just tracks and sectors on a platter (or the equivalent on an SD card). Photorec is just looking at raw data blocks and doesn't care if they're linked to a directory structure or not, so it'll "recover" them - whether the directory entry never got written, whether the directory structure was overwritten, whether it's an NTFS, ext4 or any other format storage medium. Of course it takes a LOT longer to do a full recovery on the same medium than Recuva takes, but in a lot of cases it'll recover a lot more data.
