In Mac OS X operating system, the File Vault is a utility that protects your critical and confidential data and information from unauthorized access. This tool come in-built with Mac OS X 10.3 Panther and later versions. The File Vault is a significant application that uses encrypted file system that is mounted and unmounted when you log in or log out of system or account. The home directory of the user account is encrypted using the Advanced Encryption Standard (AES) algorithms. But in some situations, the interrupted process of File Vault application might cause serious data loss situations and need Mac Data Recovery to be sorted out.

When you turn the File Vault on for your account from the Security Preferences in your Mac OS X System Preferences, entire home directory gets changed into the encrypted hard drive image. The encrypted disk image needs to be decrypted, using a password or decryption key, to access data from it.

In Mac OS X 10.4 Tiger, the File Vault can also be used to safely remove data from your Mac OS X hard drive. You can safely remove your data using the “Use secure erase” option if you have File Vault protection enabled, when you see the following message:

“You are now ready to turn on File Vault protection”

Secure erase option of Mac OS X removes all of the files that are copied in encrypted disk image of the File Vault. In case if you have selected the “Do not interrupt the secure erase process” and accidentally the process gets interrupted, you might fall in critical problem of data loss.

In case if the erase process gets interrupted due to any reason such as hardware malfunction, power surges and system crash, data erase process gets halted and you might come across below situations:

You can not log into your account, for which you've enabled File Vault protection.

All the files in Home directory, would be removed and you won't be able to access encrypted disk image.

In all such cases, data loss occurs and you need to Recover Mac Data to get your valuable information back. Recovery is best possible with the help of third-party Mac Recovery Software.
