Micro SD lost Partition

Hi,

i need some help. today i had my samsung micro sd card (64GB) which usually is used by my mobile phone, plugged in my notebook (win8.1) in order to delete and copy some files. after doing so i disconnected the device and put it back to my mobile. unfortunately the micro sd did not show up, so i tried it with my notebook again: "Insert Disk". OMG!

I managed to restore thousands of files with photorec, but without any directory or file name, moreover most of them where deleted files i do not want to recover.

however testdisk fails to find any partition, as well with "quick search" as with "deep search".

please look at the screenshots - can you give any advice how to restore the old partition?

thank a lot!

Can you repeat your diagnose and can you select your card as disk instead of a drive?
It looks like Disk /dev/sd* (*=a, b, c, etc..).
Only disk displays your partition table at Analyse and your current partition structure.

Did you use TestDisk 64bit?
TestDisk 7.1WIP 32bit is recommended.
Actually all disks should be listed and not your SD Card as a Drive only?
I'll download the latest release and test it too.
It's unusual?

Fiona

Edit:

Already tested and it works.

//ich habe keine Ahnung, warum ich gestern im englischen Forum gepostet habe, Gewohnheit wahrscheinlich. sehe gerade erst, dass du aus dem ländle kommst, kannst mich somit auch ggfs. ins deutsche Forum schieben und wir sprechen auf deutsch weiter - as you like it, i don`t care! danke nochmal, melde mich heute abend!

Mache ich doch glatt mit Verschieben.
Zuerst habe ich immer ein Auge auf deutsche Themen.

Hattest du deine Daten anschauen können?
Wenn die Partition markiert ist, geht es mit p drücken.

An deiner Stellle würde ich ertsmal alle Daten und Ordner kopieren.
Beim Listen der Daten werden unten am Screen alle Befehle angezeigt.
Hinterher sollte versucht werden die Karte zu Formatieren um sie wieder einsatzfähig zu bekommen.
Auch sollte der Status der Karte mit CrystalDiskInfo in der portable version überprüft werden.
