Topic: Recovery of files with formatted SD cards in the android-device

Prehistory such: updated the smart phone with 6.0 on 7.0 . Having updated on 7 version, decided to make the full reset, delivering a daw "to clear SD a card" being assured that the card (as it always and was earlier) will in addition be formatted only internal SD, and exterior will not be touched.
Phone informed "there is a SD-card formatting", it lasted seconds 5, and rebooted.
To my horror after reboot I found out that my exterior 64-GB the card also is formatted.
Solving, what not all is lost, I got a card, and interposing , ran full  R-Studio. It did not find any file, any signature! DMDE - the same! Only a few the empty folders created again.
How such generally can be? How it is possible to make for 5 seconds empty each sector? In what there can be a business and what it is possible to undertake in my case?
Thanks.

Very simply. Low-level formatting. If in the same DMDE it is not visible generally any signs of the helpful information - it is necessary to reconcile.

In R-Studio green color of sectors with designation Unrecognized. Really it is possible to make low-level formatting to 64 gigabytes for 5 seconds? Here scanning lasts hour. And I remember, how any software overwrote rigid completely - all is very durable procedures.
I do not persuade myself, simply technically I do not represent, as it is possible to carry out it for some seconds.

When at level of physical command by command copying of separate sectors - long.
The command to the controler, and it somehow drops. Many cameras perfectly are able to do it. Normally from a semisecond till 10-15 on overwriting of all card leaves.
