SD card with bad sectors will become unreadable. To access the data inside, you have to repair the SD card with bad sectors and recover data as much as possible with EaseUS SD card data recovery software.

"SD card has bad sectors..." How can I retrieve the pictures?

I have a 4GB SD card purchased on eBay, which has been used in a Cannon camera for some months and it's been working perfectly fine until today. When I was browsing pictures on the camera screen, suddenly I received an error message "SD card has bad sectors...". After that, I switched to the next photo, it didn't show up. Neither did the rest images. What's wrong with the card? Now I can see only parts of the photos I've taken. Will I be able to retrieve the loss? How can I repair SD card with bad sectors? Any help would be greatly appreciated. Thanks in advance.

An SD card with bad sectors surely leaves people in a panic because the data from the bad sectors will become unreadable. In another word, you're very likely to lose the data. How does a normally working memory card suddenly go bad? An SD card that has bad sectors is often caused by the following factors:

1. Cheap card of low quality bought on an online store, like eBay, etc.

2. Improper handling of the SD card. For example, abrupt removal from a camera or computer when it's still working; connecting SD card to multiple cameras with various brands and models; keeping using the card by ignoring the error messages, etc.

Usually, if people don't take the SD card with bad sectors seriously, and fail to take immediate measures to correct the errors, the bad sectors will lead to severe card corruption. In this case, the chances of memory card data recovery would be less with higher costs.
