My Android phone gives the following message when I try to format a volume (SD card or USB OTG.)
Formatting SD card will delete all data. Data cannot be recovered. Continue?
Now, this message is obviously (correctly) trying to warn the user that if they have any data they care about on the SD card, they should back it up before formatting.
However, the statement "data cannot be recovered" is factually incorrect. In fact, much of the data can usually be recovered with tools such as Photorec, Recuva and Disk Drill.
Why does this matter to the user? Well, someone may, for example, be thinking of passing on a storage medium to someone else, and want to make sure none of their naughty photos or business secrets will be retrievable by that person. A tech illiterate person who knows little or nothing about how digital data storage works, could easily take this message literally as an assurance that their data is securely deleted.
How should the message be written to warn the user about data loss while also emphasizing that formatting the volume is not a secure way to shred data?
Every OS I have ever used has warned me when formatting volumes or deleting files. But I cannot recall a single one ever pointing out that it's not really a secure way to erase the data. Why is this?
Edit (After most answers): In case anyone is curious, it's a Samsung Galaxy S3 (I9305) running stock Android 4.4.4. Here's what the process looks like:
