[chbot] Unlocking a microSDHC or SDXC card

[Henri Shustak]

Hello,

I am no aware of a software / hardware lock on a microSD card that is accessable. If this exists please someone let me know. Fascinating.

Is it possible it was somehow damaged by the phone / another device? Sometimes when solid state devices fail the controller will go into a locked state so that you can pull the data off the device. It could be that something happened and they had problems the controller figured was bad enough to look the device. I do know that some really high end malware is capable of getting into HDD / SSD controller firmware so I suppose it could be possible to do this to the firmware on an microSD card (never heard of that).

Hopefully someone will have better luck. What are these microSD cards branded and did you purchase them from a reputable supplier? If they are under warranty, you could just get them replaced.

Hope that helps.

I have tried a number of methods including trying to reformat them in a camera, using a Hard Disk Low Level Formatting Tool, using AOMEI Partition Assistant, and using SD Card Formatter. Nothing seems to be able to change the card's contents. I have two cards, one of which (64GB SDXC card) is readable, even after all of the reformatting attempts. The other (32GB SDHC card) is more totally bricked. I am not worried about the contents of these cards, just after a way to allow these cards to be reused.
