Seagate FDE hard drives encrypt the data automatically as it is read and written to the drive. As you save data to the drive it is encrypted immediately and can only be accessed when you input your user name and password. The drive will then be temporarily unlocked and allow the operating system to boot. Once the drive is powered off, it will be automatically locked again.
We have received several of these drives from customers who cannot access their data due to a hard drive failure. You may still be asked for the password, but the laptop will then fail to boot. This can be as a result of bad sectors or electronic problems. We can overcome virtually any type of failure and can return your data back to you decrypted and fully accessible on a new hard drive.
