Hardware Format write protected Mirco SD card

[Pe7ey]

I'll try to make this short...

Got a new switch/SD card and put it into the switch to check it out.
Now it's write protected.
Tried to remove the protection with "cmd" to no effect.
Any way to remove the write protection or do I have to get a new mirco sd...?

micro sd is never write protected. That is only a feature of normal sd cards triggered when the switch on the side is in the 'lock' position.

I would make sure your sd card adapter has the lock switch (it's usually a little notch on the side of the adapter) set to off. Sometimes they come already set to lock.

My micro adapter is definitely unlocked. I'll try looking for another I may have somewhere. Seems like my new adapter could be faulty then?...

(update)
put Micro SD adapter into old 32-bit laptop
wants to format it so it can read it
but shows it's 14.2gbs when it's 238gbs
would it be smart to try and let it format?

Usually when a microsd card is writeprotected, then there is something wrong with it hardwarewise. This is a way to prevent loosing the data on it completely before it gets destroyed.

You can try to recreate the partitions on the sd card and reformat it (diskpart clean and create part prim). But when it is write protected there is nothing you can do except to buy a new sd card.

238gb? Did you buy it off Ebay, Aliexpress or Wish?

Got it from walmart...
It's a PNY

It sounds broken atleast, a microsd should never turn write protected if everything works fine. Get it back to Walmart.

Just found another micro sd to test the adapter and it's definitely a problem with the adapter.
Does the switch have a good enough read/write speed to justify getting an Extreme Micro SD?

No. A class 10 card will performance the same on a switch

I've had microsd to sd adaptors with a lock switch that moves to the lock position just by inserting, which is annoying but can be fixed with some tape.

I've also had sd to usb adaptors where the lock switch detection stops working and I had to solder it so it thought every card was unlocked.

Actually a A1 rated card will perform slightly better for games. It's optimized for random IO which is a good match for games.

Restarted my computer for an unrelated reason and now I seem to have write access...
Formatting it to FAT32 since that seems recommended.

You never know what kind of trickery fixes this write protection nonsense. Sometimes its a problem with the port, the adapter, the card itself...
i would advise you to use h2testw to check if the card has any issues itself though.
takes lots of time but better than finding out that, after transfering 100gb, the card just break or something.

as for speed. class 10 u1 cards should be just about the norm at this point and they work well enough.
u3 cards (i think the extreme sandisks are u3) are slightly faster, but not by much, not worth paying almost double for on the switch.
