Windows Won't Detect Any 8GB SD Card
According to the Secure Digital (SD) Card Association website, the "small, postage stamp-sized memory cards are the most popular storage cards in the world." They come in many different storage capacities, but only cards 2GB or smaller are truly SD cards. Cards 4GB and higher are Secure Digital High Capacity (SDHC) cards; as such, your 8GB SD card is actually SDHC and may require a free download to be used on your Windows computer.
Check the user manual of your computer or SD card reader to see if it can read SDHC cards. If it doesn't state that it's SDHC-compatible, download the latest card reader drivers from the Microsoft website.
Eject the SD card from the reader and examine the contacts. If you see any markings or debris, clean it with a lint-free cloth and reinsert it into the reader, pushing until you hear a click.
Click the Windows "Start" button and click "Computer" or "My Computer" and look for your 8GB SD card under "Devices With Removable Storage." If you don't see it, eject the card and try reinserting it.
Format the card by entering it into another computer or any device that accepts SDHC cards. If you insert it into another computer, click the Windows "Start" button and click "Computer" or "My Computer." Right-click your SD card under "Devices With Removable Storage" and select "Format." Select "FAT32" and click "Start." Wait for the format to finish, then eject the card and reinsert it into your computer.If you insert it into another device, look for the "Card" or "Memory" option in the main menu and click "Format." When the format is finished, eject the card and reinsert it into your computer.
