I have a Sandisk Ultra Class 10 8GB microSD. When I plug it into my laptop with a microSD adapter, I can not write on it.
When I try to copy a file on it, the write operation seems ok. But when I replug it, I can not see that file.
I can not erase partitions. I can not format. Whatever I did is no go.
It looks like it is in some sort of read-only mode.
Is there any low-level tool to check what is going on the card?

Thanks for your reply drlucky.
Card is rather old, so no warranty anymore.
Is there anything I can do to turn it back to write enabled mode?
Does it mean flash chip on the card is somehow damaged and therefore sd-card is useless anymore?

No, once the card locks down in write protection it cant be removed.
the ultra cards have like a 5 or 10 year warranty so it may be worth checking the warranty status with sandisk support.
