How to overcome write protection on micro sd card

They typically have a small switch or tab that is easily pushed that will cause write protection. If that is not the cause, then it may need to be reformated.

Removing the write protection depends on the source of the problem.
Broadly speaking, it can be any of the following scenarios
1. There is a write-protection tab on the mini sd card HOLDER. Every time you insert this into your PC or card holder, this tab slides to the write protect position. Either keep resetting, inserting & reinserting until it doesn't slide or tape it down.
2. There is nothing wrong with the mini sd card. Simply locate the write protection key and push it.
3. The mini sd card has some error: Go for a low level formatting.
4. The card has virus: Remove the virus. The link for the steps is present in the related link at the bottom of the article.
