Formatting. What does it mean? Does it really delete everything? You’ll often see formatting being posed as a solution to fix various SD card problems. How could one action fix so many issues?
This article aims to answer all your questions. We’re going to discuss what formatting is, what it does, and how to recover data from an SD card, even after formatting it.
Does Formatting Erase All Data?
Formatting is the process of refreshing the file system your SD card uses. Essentially, it’s like resetting your SD card (which is why it’s an effective solution to fixing a lot of issues). No matter what, this process will delete the data on your SD card. However, the type of format you perform is important in understanding how recoverable your data is, as data can be recovered even after a format is performed.
To answer the question “does formatting erase all data?”, let’s break down how each type of format operates.
- Quick format – Performing a quick format will delete the data on your SD card, but not completely. You will still have a window for recovery until new data is written to the same location as the old data, effectively overwriting it.
- Full format – A full format rewrites each sector of the drive. This overwrites the existing data, making it impossible to recover. Additionally, a full format checks the entire drive for bad sectors, which can save you from problems later on.
Even after a full format, data can still be recovered with the right knowledge and tools, though chances are very low.
How to Recover Data After SD Card Formatting
If you performed a quick format on your SD card, whether it be accidentally or purposefully, there’s a chance that your data is still recoverable. You can even scan a fully formatted SD card, though it’s improbable that any data will appear. To do so, you need to use specialized recovery software, like Disk Drill. Disk Drill is capable of reading your SD card and finding information that’s not available in the traditional File Explorer.
Follow these steps to recover data from an SD card that was recently formatted.
Once Disk Drill is finished recovering your data, it will display how many files were recovered and provide a shortcut to the output location.
How to Increase Your Chances of Successful Data Recovery
Encountering data loss for the first time can lead to lots of mistakes, such as improperly formatting the SD card or copying new data to the SD card to see if it still works. If you’re unfortunate enough to be the victim of data loss, there are a few things you can do to maximize your chances of successful data recovery.
- – Every new action on the SD card puts your data at risk of being overwritten. In its current state, your data can easily be overwritten with new data, resulting in your original data becoming basically unrecoverable.
- – Never recover data to the SD card you’re performing recovery on. Data can not only overwrite the data you’re trying to recover, but it has a chance of corrupting the data, further decreasing your chances of recovery.
- – When possible, make a byte-to-byte copy of the SD card and recover data from the file instead. Performing recovery on the file instead leaves the original SD card intact, reducing the potential of critical errors.
Making use of these tips, especially recovering from a copy of your SD card, can contribute to a successful recovery of your data. Once you’ve recovered your data, make a backup to protect it against future data loss scenarios.
Formatting an SD card involves refreshing the file system it uses. This, as a result, removes any data on it. For instance, formatting a Sandisk SD card will delete all of its contents and leave you with an empty SD card that’s ready to store new data.
Formatting an SD card on Android is the same as formatting it on a computer. You’re formatting the SD card with a new file system, which will delete all data that’s currently on it, including any internal files that are hidden. Mobile devices often offer a quick format option as opposed to full format.
Conceptually, erase and delete often mean the same thing. If you’re asking yourself, “does formatting an SD card delete everything?”, the answer is yes. In terms of erasure though, this depends on the format type you use. Performing a quick format will delete your data but retain some information that can be used to recover it. A full format or secure erase, however, will often result in all data being erased completely.
