SD cards and Micro SD cards are arguably the most important basic requirements for the storage and access of digital photos. They can be accessed by a number of different devices.
- Digital Cameras
- Mobile Phones, Smartphones and Cellphones are most common.
- SD Card Readers
Over time, SD cards have proven themselves to be the most convenient way of digital storage. They owe this to their compact size. They’re much smaller than other options such as mini-CDs or DVDs. Also, they have a long life span and are not easily damaged.
The easy portability of an SD card or a Micro SD card also makes it very appealing to users. The fact that they can be used by a number of devices ads to their popularity.
Corruption of SD and micro SD Card Data and Prevention.
The use of an SD card is the most common way to store digital photos in a camera. No matter what storage method one uses, corruption or loss of data on a microSD flash drive can occur. Thus, despite the user’s best efforts, it happens. However, as technology has progressed, storage media has become more and more durable. Today, it’s more difficult (but not impossible) to accidentally lose information on SD cards.
Loss of data on an SD card can be prevented by taking the following precautionary measures.
- Safely remove the SD card from the computer.
- Avoid filling up of the microSD card completely.
- Reformat the microSD or SD card periodically.
- Switch the camera off before ejecting the SD memory card.
- Avoid exposing an SD flash card to extreme temperatures.
SD card manufacturers recommend users always remove cards safely from the computer at all times to ensure that the data is completely saved. In OSX, this can be done using the eject command. In Windows, the same can be done by choosing to safely remove hardware before pulling out the SD card. When removing an SD card from a digital camera, turn the camera off before removing the card.
Also, do not turn the camera off immediately after taking a photo. This is especially true when taking photos in burst or continuous mode. This mode takes a number of pictures very quickly, and after taking these photos, it takes time to save them completely to the microSD card because they are fairly large files. The DSLR camera can produce heat in the SD memory card. Switching the camera off immediately might interrupt the process and result in the loss of images or damage to the microSD card. microSD and standard SD memory cards will become hot and could be damaged. Check to see if your SD card is getting hot. If so then purchase a SD card or micro SD card with a faster transfer speed.
Deleted data should be done on a computer rather than on the camera. The fewer times the card’s information is accessed and deleted, the longer its life. Therefore, it’s better to copy all the images to a computer and then erase them in bulk rather than deleting them individually from the camera. When removing all images from a card, format it completely.
Handling SD cards carefully goes without saying. They should be kept dry and clean. Keep cards out of direct sunlight for extended periods of time. The card shouldn’t be bent, dropped, or punctured.
In the event an SD card or Micro SD card begins showing an error message, immediately stop using it to avoid further damage. Using a card after it starts showing signs of damage can result in a loss of all the information on the card.
Recovering Digital Images from SD or micro SD Cards.
The loss or corruption of data on an SD card or Micro SD card can be caused by a number of problems.
- Unintentional formatting of the card.
- Loss of data.
- Wrongful deletion of images.
- microSD Cracks or Bending by Accident.
- Dog bites that crack the SD card.
- SD card overheating due to consistent saving of photos taken quickly.
Once the camera flashes an error message related to the SD card, stop using the card. Remove the card from the camera. Connect it to a computer, and check if the error message still appears.
If the error message doesn’t appear, copy the images and format the card. However, if an error message is displayed, eject the card safely. Do not format it or use it again.
As long as the images are available on the card, they may be able to be retrieved. A data recovery service like eProvided can help retrieve data that has been lost. The images and data may be extracted successfully. In some cases, the SD card may be repaired and usable again, but in many cases, the damage is permanent and the card will need to be replaced. SDXC and SDHC cards are usually faster versions. Check your SD memory card speed ratings.
