In a nutshell, you shouldn’t use iOS Recovery Mode unless you first created a complete backup of your device before doing so. For the most part, metadata is utilized in computer forensics investigations to provide a record of phone usage – for most folks this data is going to be useless. Calling it a Format would frankly make much more sense, but sadly it is what it is.ĭata recovery engineers from Hard Drive Recovery Associates may be able to retrieve metadata from iPhones and other iOS devices after performing a complete reset to the factory settings. Nevertheless, the Recovery Mode delete command is not like other delete commands rather, it performs a format operation on the device, bringing it back to its original settings. There are, however, a few notable exceptions: After an ordinary delete command has been executed on a device running iOS 12 or an earlier version, the user’s photos, videos, internet browsing history, and text messages may still be retrievable. When data is deleted from an iOS device, the encryption key is also removed. This means that each file has its own special encryption key. When the charge isn’t there anymore, neither is the data.įile Based Encryption: The iPhone encrypts the majority of the user’s files using encryption that is based on the individual file. The data is rendered permanently unrecoverable as a result of this process, which involves clearing the charges from the transistors. A garbage collection process is utilized by NAND flash media in order to improve efficiency and maximize storage space. ![]() When data is deleted from flash drives, it is typically removed from the device permanently. In order to store data, transistors are used to hold electrical charges. This technology was developed by Flash Media Engineering. There are several reasons why deleted files on an iPhone cannot be recovered through normal means:įlash Media Design: iOS devices use NAND flash, a type of non-volatile memory consisting of transistors arranged into a grid. ![]() In most cases, data that has been deleted is completely irretrievable and cannot be recovered, even by a data recovery company. When activated, the Recovery Mode on an iPhone from Apple will delete all content from the device, and is certainly not a great thing to do without absolute certainty.
