sd card recovery macYou’re transferring files from your SD card to your computer when you accidentally delete some valuable footage. Whether it’s a simple photo or a professional video clip, we can recover deleted files from your SD card through your Mac.

Before anything, you should immediately stop using the SD card to increase the chances of recovering your deleted files. In this article, we’ll go through a step-by-step guide to recovering the deleted files and we’ll talk about the common reasons for data loss and how to avoid them.

Types of SD Cards Explained

SD or Secure Digital cards are portable memory cards used to store data in electronic devices. 

Here are the different types of SD cards you’ll encounter.

  • SDHC – These are the most common type, with high capacity storage that can hold up to 32GB of data, so they are usually used for digital cameras.
  • Micro SD – These cards are smaller in size and are designed for mobile phones.
  • CF Cards – Compact Flash cards are known to be faster and more durable than SDHC, and are mostly used in high-end cameras.
  • xD Pictures – Extreme Digital picture cards were commonly used with Fujifilm and Olympus cameras, though they were discontinued in 2009.

Even though there are several types, the ways to recover deleted files from SD cards are similar, if not exactly the same. So without further ado, here’s how!

Reasons for Data Loss from SD Cards

There are several possible reasons as to why you’ve lost files from your SD card. The most common reasons are:

🛠️ Corrupted Card

Improper physical handling of an SD card can result in a corrupted card. When your SD card cannot be recognized or cannot show files saved on it, then it may be corrupted. Aside from improper handling or exposure to heat and unsuitable environments, age can also degrade and slowly corrupt an SD card.

An SD card typically has a 10-year lifespan, but it’s a great rule of thumb to prepare backups and think about buying one after 5 to 7 years of use. This is especially true if you’ve used your SD card on a consistent basis, since these cards only have a limited number of reading and writing operations.

🦠 Virus or Malware

If your device accidentally downloaded a malware or virus, then that will also affect the memory card installed. Data stored may become unreadable or inaccessible. 

💿 Formatting

Formatting a memory card on Mac, whether intentionally or accidentally, deletes all the data that was stored in it. Unless you are sure that you no longer need the files stored in your SD card, or you have them all backed up, do not format your memory card. 

How to Prevent Data Loss on an SD Card

Knowing all that, here are a few tips for you to prevent data loss:

  • Always safely eject your SD card after using
  • Avoid using or placing your SD card in high temperatures to avoid damage
  • Use multiple memory cards for extra security
  • Do not remove your SD card while read/write operation is in progress
  • Regularly backup your files.
