The harddisk (63 GB / 59 GiB) seems too small!

#1 Post by saskiav » 19 Sep 2016, 05:11

I was transferring a .png screenshot from device memory to memory card when i got an error message that the file was unrecognized. Memory card was about 80% full at time of unfortunate event...

The files are in folders and subfolders. The folder with the naughty .png can be deleted. But I would like to recover the others, if possible (mp4, amr, jpg, mp3)

Phone shut itself down and rebooted.
Memory card folder is no longer visible on my device.
Memory card is recognized by my laptop but with a message to reformat.
Partition is visible but shows a size 59.06 GB instead of the original 64 GB

Phone: Android mini s4:
Memory Card: Patriot SDXC 10, 64 GB
Laptop HP15: Windows 10

Would greatly appreciate guidance on how to best proceed.

The harddisk (63 GB / 59 GiB) seems too small! (< 76 GB / 70 GiB)
Check the harddisk size: HD jumper settings, BIOS detection...

The following partitions can't be recovered:

Try TestDisk, Advanced, Boot, RebuildBS, List. If you can see your files, choose Write, confirm, Quit
If it doesn't work, try PhotoRec instead https://www.cgsecurity.org/wiki/PhotoRec_Step_By_Step
