Cleaning a MicroSD card can mean one of these things:
- The outside portion of the card is dirty or damaged, which you can clean it up and see if the card is in a working state
- Another possibility, when the card is filled with useless files, cleaning also indicate deleting everything from the card!
Which one are you? Well, if it is the first option, then it is easy. If you are looking for the second one, then you might be wondering what could be the ways for cleaning MicroSD card. Some might suggest you to just delete the pictures that you feel no more needed on the card, or few may say to format the card in the camera, or others may tell you to go with low-level formatting.
But for those people who are new to the world of digital photography, the above advice will be bit confusing and disputing. They may get afraid of doing new things which may probably go wrong! Even wonder what if I just delete the photographs? Why is the formatting a better option?
But, there is no need to be worried. We all are here to learn and this article simplifies the things and helps out in choosing the best method for cleaning the MicroSD card.
Let’s begin with some basic idea of data storage. Just assume your card as a simple book with Table of Contents (TOC) and pages, say 50 of TOC and 450 of actual content pages. Total 500 pages’ book. Whenever you take a picture, the camera writes all the info to the page and notes that page in TOC. That’s all the analogy.
You are done with clicking pictures and also transferred the files onto your computer. And now you want to clean the memory card. So here are the methods you can pick up.
When a photo is deleted, what happens is that the entry in TOC of that particular picture will be deleted, but not the actual information available in the page. This then allows the camera to know that the page is available for new data. Only the TOC will get affected, not the actual pages when you delete. The camera only looks into TOC, but not the pages. According to it, there is nothing on the page and it is available to be overwritten.
There will be an option called Format on all the cameras. This option is a quick way for deleting files from the card in one go. Just like the deleting process, formatting also removes the entries from TOC. Only the difference is it does at once. So we can say that it is only a TOC operation again, not a book function while high-level formatting of a MicroSD card.
This is where the real culprit comes in! When you perform low-level formatting on the card, the camera not only erases the entries from TOC but also each letter from every page. At the end, you will be just left out with a book with pages’ written zeros everywhere.
NOTE: Before performing any of these methods, just make sure that all important files from the card is backed up to a safe drive. In all these methods, file from microSD card will be erased. In case you need any file after erasing, then with this backed up copy you can restore your microSD card data whenever you need. But, if no backup is taken, and still you want those erased data back then you can go for Remo Photo Recovery software.
Now let’s conclude which way is better to cleanup MicroSD card…
If you are looking for the maximum amount of space and really want to have the cleanest card, then go for low-level formatting provided your camera should have the option. As deleting pictures from the card and a High Level Formatting doesn’t yield much benefits.
Well…this is all about how data is stored on MicroSD cards and how you can clean-up them. We can’t conclude which method is best but hope this article will help you in future to take an informed step. Which way you opt for totally depends on your decision.
