End-to-End error S.M.A.R.T. parameter is a part of HP's SMART IV technology and it means that after transferring through the cache RAM data buffer, the parity data between the host and the hard drive did not match. For detailed information see SMART IV Documentation from HP.
This is a critical parameter. Degradation of this parameter may indicate imminent drive failure. Urgent data backup and hardware replacement is recommended.
