Secure Digital Cards, also known as SD cards, are the perfect way to store a decent amount of memory on a very small-sized space. Cards can be moved from PCs to cell phones and cameras and other devices with ease, however, in some cases, you may want to change the size of the card being used, and therefore it is important to understand how larger 4GB SD cards can be used in slots that you've been using your 1GB card in.
Instructions
1. Check what type of cards are support by your memory card slot. There are two major types of SD card slots: standard SDIO slots and SDHC (high capacity) slots.
2. Check if your 4GB card is an SDHC card. If it is you'll need support for that card type. If your card is not supported, the device manufacturer may have an SDIO-to-SDHC upgrade. You'll need to check with the manufacturer.
3. Remove the 1GB SD card and replace it with the 4GB card once you have determined that the drive supports your card. You may need to choose the "Format" option found on your device. If your device does not offer card format support, you can place the card in a supported computer and format the drive as you would a standard hard drive via the "My Computer" screen, which will display your SD card drive.
4. Test the card by loading a file onto the drive and then attempting to open the file. If the file opens, your new 4GB card is supported.
