Accidental deletion or drive formatting are the two leading causes of data loss. Be it an internal drive or an external storage device such as an SD or a compact flash (CF) card, accidents do happen and might leave you unnecessarily distressed. These days, most professional cameras come with an SD or CF card slots for storing the captured photographs; this allows the user to store large amounts of data (especially in the case of CF cards). When you delete a file or a folder, in the file index, the space occupied by that folder/file will be marked as empty, so that new information can be written on it. Formatting is similar to deletion in the sense that formatting erases all the data on the drive, all at once.
The system usually does not overwrite the space previously taken by a now-deleted file; it merely marks that space as ‘available.’ The system will never overwrite on this ‘available’ space unless it runs into low disk space; in that case, only it will overwrite on this ‘available’ space. Till then, there is always a scope for the recovery of deleted data.
Common reasons for data loss from CF cards
- Accidental deletion or formatting of drive: It is one of the reasons for loss of photos . Sometimes the deletion can be intentional too and formatting of the drive is another reason for the data loss.
- Physical damage: physical damage to the device in which the memory card is inserted can in-turn harm the memory card.
- Damaged hardware: You may have received a faulty memory card from the vendor . Some firmware damage can be the result of virus or a malicious attack also.
- Improper handling of the device: Improper handling of CF cards such as improper ejection of the storage device, can corrupt the photos stored on the device and cause consequent data loss.
- Storage issues: If the memory card is running out of space, then it can lead to the automatic deletion of photos and even give rise to corruption.
- Virus or malware attack: A virus or a malware attack can overwrite the data on your storage device and can severely corrupt your photos.
Tips to prevent CF card damage
It is essential that users make a habit of the practices given below to reduce the likelihood of corruption in CF cards and avoid potential data loss. Some tips to prevent data loss in CF card are:
- Take frequent backups: Taking routine backups of your photos ensure that in case of any unfortunate scenario, users won’t lose their valuable data.
- Proper storage: Ensure that your CF card is stored properly in a safe case with a stable temperature which is neither too hot nor too cold to prevent any physical damage.
- Format occasionally: Formatting your CF card routinely reverts it back to its factory setting, ensuring that your CF card remains in a good condition.
- Dedicated CF card: Using a single CF card for several devices can give rise to corruption which may lead to data loss. It is advised to use a CF card for one device only.
Methods to restore photos from a CF card
