Reformatting Old Micro Sd card

Yeah I mean if you still have the dashcam of course put it in and see what happens. I suspect its the way it set it up that's caused the problems if in fact it isn't dead.

@night.fox : I thought that in the event of an accident the files lock so they can't be overwritten, (for legal evidence submission) Like a protected partition.
Does the card work for other things? Could you format NTFS or FAT32 and use the remainder (unprotected) area like that?

Perhaps as INSTG8R said, another dash cam can unlock or remove that protected area???

EDIT: https://www.sdcard.org/downloads/formatter/
SD/SDHC/SDXC Cards have a “Protected Area” for SD Card security purposes. The SD Memory Card Formatter does not format the protected area in the SD/SDHC/SDXC Cards. The protected area shall be formatted by an appropriate PC application or SD host devices that provide SD security function.

When I used linux, I could see some space like 300mb or even less. I have formatted that but it cant. Have tried formatting to any other file systems, ntfs and exfat. Windows shows it is formatted. But once reinserted, it came back original state. Same message for linux. But most of the time, it shows cant be fornatted.

I have the other day inserted to my dashcam and to a friends daschcam but message says cannot be formatted.

I have tried formatting (after backup) my dashcam existing memory card and it can be formatted like usual.

So most probably, that dashcam on my old car have that security implementation which it can be only be edited by manufacturer.

Unfortunately, I cannot remember what brand that was. But as I recall, it is a very cheap model and only recording at 480p.
