Have 32gb micro sd memory card for phone which worked at first. Now will not format or open.
Also says it is 8mb now and is write protected. Any advice??? (apart from bin it)
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.
