An 8 GB microSD card showing as 1.3 TB in Windows 7

Question

My 8 GB microSD card is showing as 1.3 TB in Windows 7, and I am unable to format it. How can I do it?

Note: it's been formatted with ExFAT.

Answer 1

Might be an issue with the controller reading the card. Try:

• checking Windows Update to see if there are updated drivers for your SD reader drivers
• using a different device to read the card (try your phone if it has an SD card slot)

Answer 2

First off, SD cards bigger than 4 GB are not normal SD cards - they are the "new" standard called SDHC, which means it's possible your card reader doesn't support it. Check it out first, or as ultrasawblade suggested, try putting it in a phone and connecting that via USB.

Otherwise, in Windows 7 you could try using Disk Management tool to delete/re-create the partition and re-format:

1. Right-click on the Computer icon on your desktop and select Manage (or alternately via the Start Menu > Computer > right-click):
   

2. Now, click below on Disk Management:

3. Find your drive, right-click and select Delete Volume.

4. Right-click again on your drive and select Create Volume

5. Right-click yet again on your drive and select Format

6. Enjoy your newly formatted drive(?)
