Memory card corrupted in Canon EOS 7D Camera

Embedded with brand new features, Canon EOS 7D digital camera is a delight for all the photographers. The camera with 18 mega pixel captures tremendous images and videos and stores them on the CF (Compact Flash) memory card. These cards, although considered to be safe media of storage, can be corrupted due to numerous reasons. Corruption of these cards primarily results in inaccessibility of all the images and videos stored in the cards. In such cases, these multimedia files can be easily accessed from a valid backup, usually created on a computer system. However, if a photographer has not created any backup or backup is incomplete, then the photographer needs to use an advanced third-party Card Recovery Software.

Consider a practical scenario, where any of the below error messages are displayed on the LCD monitor of the Canon EOS 7D camera:

“The card cannot be used”
Or
“Card cannot be accessed. Reinsert/change card or format card with camera.”

After the above error message appear on the LCD screen, the data stored on the CF memory card becomes inaccessible. Furthermore, these error message do not allow you to click any new images or videos.

Cause:

The root cause for any of the above error messages is corruption of CF memory card. Few major reasons for corruption are improper handling of camera, interrupted read/write operation, and virus infection.

Resolution:

The only possible way to resolve the above problem, in case of backup unavailability, you will need to format the memory card with camera (as suggested in error message). But, once the card is formatted, the data saved on it gets erased. The formatted images, videos, or any other multimedia files can be only recovered by using an advanced Card Recovery application. The Card Recovery utility allows recovery in three simple steps, download the software from Internet, connect card to your system, and run the application. With easy to understand documentation, the photographer can easily perform the recovery process. The software is completely non-destructive as it does not makes any changes in the original data stored on the memory card.

Stellar Phoenix Photo Recovery is an effective Card Recovery that ensures complete recovery of data from almost all formatted memory cards, including CF, SD, and SDHC. Compatible with almost all file types, the software is designed for Windows and Mac OS X. The software can recover data from other storage media as well.

Photo Deletion due to empty cell phone battery

A memory card used in a cell phone works in the same way as they are used in digital cameras. These digital devices follow a read-write process to save data onto the memory card. Pulling out the card while the phone is on, or the phone switching off suddenly due to an empty battery, while the read write process is ongoing, interrupts this process, and leads to card corruption. This further results in inaccessibility of data stored on the card. This data can be recouped using a card recovery software, in case of unavailability of adequate backup.

For example, when you use a memory card in a cell phone and the cell phone displays a ‘low battery’ sign, the tendency is to persist in using the mobile phone to take pictures and videos until the battery dies out completely. After this, when one tries to view or even save any more pictures to the card, he/she is unable to do so. Moreover, one gets an error message while attempting to access the data:

‘Memory card is corrupted’

After the error message, it is clear that the card in not usable—neither to view nor add pictures.

The cause for the above error message is that the read-write process of the card was interrupted unanticipatedly. This leads to card corruption. Once a card is corrupted, the phone and the computer cannot read the data, which is why the files can not be viewed.

The only way to resolve the problem is to format the card. Formatting a card sets up a new file system that enables the card to interact with the cell phone. This is why the formatting should preferably be done in the phone itself rather than on the computer system. However, once the card is formatted, all the data on it gets deleted. These formatted multimedia files can easily be recovered using a Card Recovery Software. To perform Card Recovery, one only needs to download the utility tool from the Internet, connect the card to the computer (ideally using a card reader), and run the software.

Stellar Phoenix Photo Recovery is a Card Recovery tool that enables users to recover lost files in three simple steps: Select the corrupt drive, scan it, and then save the recovered data. The tool supports recovery of numerous files, like JPEG, GIF, BMP, M4A, MP3, etc.. It can recover data from almost all popular storage media, such as, memory cards, memory sticks, Zip disks, etc.
