Line 1: '''Time-Limited Error Recovery''' (TLER) is a name used by [[Western Digital]] for a [[hard drive]] feature that allows improved error handling in a [[RAID]] environment. In some cases, there is a conflict whether error handling should be undertaken by the hard drive or by the RAID controller, which leads to drives being marked as unusable and significant performance degradation, when this could otherwise have been avoided. Similar technologies are called '''Error Recovery Control''' (ERC), used by competitor [[Seagate]], and '''Command Completion Time Limit''' (CCTL), used by [[Samsung]] and [[Hitachi]]. ==Overview==
