It can be frustrating when your Canon digital camera seems to be taking longer than usual to read or write data. Perhaps this delay is getting in the way of capturing certain moments, or eating up precious time as you wait for your images to load.
You may want to get rid of this marked lag but not know how to, wondering to yourself: why is my Canon so slow to shoot and display images? For me, it did not initially occur to me that the SD card, or Secure Digital card, was at fault for the slow camera speeds.
Fortunately, in just a few steps you can solve this issue simply by formatting the SD card on your Canon digital camera. Formatting an SD card is also recommended when using a new SD card with your Canon camera.
When you format an SD card on a Canon camera, you are essentially initializing the memory card and deleting all of the data on the memory card.
Note that Canon cameras offer low level formatting as well as standard formatting. The former offers a more thorough cleansing. Because low level formatting completely erases all of the recordable sections within your SD card, it will likely take longer. However, it will restore your Canon memory card to its full working capacity, akin to its "brand new" state.
As noted above, formatting will erase your data. You want to ensure that all of your photos have been saved and transferred prior to your SD card formatting. If by any chance, you've erased the card without backing up the files, see this post how to recover Canon pictures or this one unformat camera card for solutions.
Be careful not to mishandle the SD card or touch the gold contacts. In addition, you want to keep your SD card in a safe environment (i.e away from extreme temperatures).
Now your SD card is blank and formatted. It should no longer lag when writing or recording new data, and it will now be compatible with your camera (if you're using a new memory card).
