SD card with bad sectors will become unreadable. To access the data inside, you have to repair 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.

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 turn to bad? An SD card that has bad sectors is often developed from the following factors:

1. Cheap card with low quality bought on online store from eBay, etc.

2. Improper handle with SD card. For example, abrupt removal from camera or computer when it's still working; connect SD card with multiple cameras with various brands and models; keep using the card by ignoring the error message, etc.

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