Removing write protection from MicroSD card?
Hey there. Subject says it. Regular SD cards have a physical switch but MicroSD don't, yet I can't use this because it's reported as write protected. Any suggestions? Is it a micro-brick? Thanks!

I have a card in that state. I have never found a solution to fix it. Pretty annoying. -- Len Sorensen
Micro SD don't have a switch, so it's on firmware or something like that. https://unix.stackexchange.com/questions/138518/how-to-format-write-protecte... says hdparm can help. On Feb 2, 2018 19:00, "Lennart Sorensen via talk" <talk@gtalug.org> wrote:

Unfortunately I suspect that at least in my case the card may in fact have failed and gone read only to protect any remaining data. It was being used to increase internal storage on an HTC 10 phone, and I have found a lot of people who say they have had cards (usually Samsung cards) die in quite a short time when used that way. -- Len Sorensen

One basic check to do is make sure the file system on the device isn't corrupt. If it is that could account for it being mounted read-only. -- Cheers!

I can't even overwrite the entire card using dd. It's not the filesystem that is readonly, it is the block device. -- Len Sorensen
