Your file system is some FAT 32 (or some FAT modification). It has limitation. Limit is on 4 GB but sometimes can be less. You must convert it to NTFS system. You can use Exporer for that purpose (righ click on drive and Properties), or format it with NTFS option. But with NTFS lot of cheap devices will not work (they must pay to Microsoft lot of patents for compatibility). Windows or Linux has not problem with that kind of memory card.

You might be using a memory card with a larger capacity than your device can use. But as you haven't given any details regarding the make and model of device it's impossible to be certain.

One thing is certain though: FAT is a Windows formatting system. Just because they use it, it doesn't follow that other devices do; most cameras and phones use their own proprietary formatting system. To be safe, NEVER format memory cards in anything other than the device they're intended for, you can ruin them for use in anything other than a pc.

You can also try formatting your drive using disk management.To do so:-

• Just right click on My computer.
• Select Manage.
• Select Disk Management
• Find and select your Pendrive and format it.

Alternatively, you can open it from the command prompt

• Open the command prompt and type diskmgmt.msc.
• Press Enter
• Select the pen drive, right click on it and click on Format.

If you using your microSD in phone,better you format the card using your phone
Thats it !!

Hello,

I've been encountering this issue. The problem may come from the card reader or the card holder. If possible, use a different card holder and of problem persists, try a different card reader or test on another computer.

Hope this helps!!

In that case the card is defective and unfixable. Get a new one.
