What Does End-to-End Error Mean

The first thing you need to figure out is the meaning of the end-to-end error. In fact, this error is usually detected by Hewlett-Packard’s SMART technology or other vendors’ hard drive I/O error detection technologies.

That is to say, the end-to-end error only appears on hard drives supported by the SMART attribute or other similar technologies. According to a survey, these hard drives come from Samsung, Seagate, IBM (Hitachi), Western Digital, Hewlett-Packard (HP), and Maxtor.

The SMART technology can detect an amount of parity data errors while transferring data via the hard drive’s cache RAM. If you receive the end-to-end error, it indicates that the parity data between your host and the hard drive cannot match.

Bear in mind that the end-to-end error is a critical parameter that means an imminent hard drive failure. So, it is highly recommended that you make a full backup of your hard drive in order to avoid any unnecessary loss.
