I unpluged too fast my ScanDisk microSDXC Ultra 64Gb from my phone. Now i can see free space (27Gb) just in my PC-WIN7-64bit. In my phone-Galaxy GT-N7000 the card is not recognized. The used place (33GB) can not be seen (probebly in RAW file system).
I saved allready all the data with testdisk.
TESTDISK in Win7 write the following partition can't be recovered


edit: Linux see all the sizes, i can format the card in any format(fat, ntfs, extFat) but in Win7 i see just the last free space 27GB


I did allready some test in Parted Magic following instruction byJames Litten from similar topic.

Disk /dev/mmcblk0 - 63 GB / 59 GiB - CHS 1948992 4 16

Warning: the current number of heads per cylinder is 4
but the correct value may be 128.
You can use the Geometry menu to change this value.
It's something to try if
- some partitions are not found by TestDisk
- or the partition table can not be written because partitions overlaps.



After deaper seacher the same like ^^
