The Request Failed Due To A Fa

Have you ever met “the request failed due to a fatal device hardware error”? Do you know what does this mean exactly? And do you want to recover data from the device on which such error appears? I guess the answers to those questions are “yes”, “no” and “yes”. The not accessible fatal device hardware error (once this error occurs on a drive, that drive will become not accessible) shows up now and then on different devices (WD external hard drive and Seagate hard drive are two most common devices).
