SD cards are compact memory cards with huge amount of storage space. Since they are compact in size, offer huge amount of storage space and retains files without power, most of the digital media devices like digital cameras, mobile phones, camcorders and others prefer SD cards to store the data. Most of the times SD cards deal with media files like photos, videos, etc.
Along with the popularity of SD cards, their data complexity also increases gradually. There are many cases in which data stored in SD cards misused by other people. Simple deletion of data from SD card will never erase the stored files. They can be easily recovered with the aid of recovery software. If you are looking to delete the data stored in SD card for ever, then you need to shred files from SD card with different shredding patterns.
If you just delete a file stored in SD card, only the index file which is responsible for deleted file manipulation will be removed and storage space marked as available but the actual data still resides on the stored sector until it is overwritten with new data. Such files will be inaccessible only for operating system but data recovery software easily retrieves such data by performing a sector by sector scanning.
Prior to discussing how to delete a file beyond recovery let us see the scenarios in which user needs to permanently delete the file.
- In case if you are thinking to sell a SD card which you were using to capture photos, then it needs to delete all the files beyond recovery, because someone else might recover your files which eventually leads to misuse the photos.
- When you are handling your SD card to your colleague or subordinate at work, it is good to erase the stored files beyond recovery.
In order to delete a file beyond recovery it needs to overwrite the stored sector with random values, which is practically impossible, because no one likes to manually trace the stored sector of the file in SD card and overwrite with random values, but a file shredder easily shred the files with different standard shredding patterns. They will overwrite the stored space of a file with standard file shredding patterns.
