![]() This encryption process is transparent to the user and to the operating system. ![]() Each drive has a unique encryption key, which results in every drive, given the same data to write, saving uniquely different data patterns to the media. This is perhaps better explained from Seagate’s FAQ:Įvery Seagate FDE drive is built to encrypt all data, all of the time, right out of the box. In its default mode of operation though, an SED will decrypt any data upon request, functioning identically to a non-SED drive. This key can only be changed using specialized (but available) tools, and doing so destroys any existing data. With an SED, data written to the drive is always encrypted using a manufacturer-set encryption key. It functions identically to a non-encrypted drive after authentication. All operating systems and platforms are supported.Encryption is always on and cannot be disabled.Performance of the computer is unaffected as the encryption is done by the drive controller and not at the operating system level.There are number of benefits to this approach: A number of departments on campus have started to use ATA password security in combination with Full Disk Encryption (FDE) drives, or Self-Encrypting Drives (SED), to comply with the mandatory encryption policy for portable devices without having to install encryption applications such as SecureDoc.
