Here's a good read on this topic: https://www.gillware.com/digital-for...d-nand-memory/ |
Conventional recovery software does not work against magnetic platters. It works against the storage's logical (firmware) interface. Just as the read suggested explains
, the recovery trick is in "logical-to-physical mapping" solely. For both HDD and SD card. It's just SD card has it different and more complicated. A logical recovery is still available for SD cards. It's just there's a physical recovery "last chance" option beyond the logical interface which is opaque in fact. The simpler method should be tried first, of course.
