(For units which are not redundant,this option is not shown on the screen.) When this policy is set, ECC (ErrorCorrecting Code) errors are ignored when they are encountered during arebuild. (ECC errors are typically defects that have been detected in the drivesince initialization.) When this policy is not set, if a unit is rebuilding, therebuild will abort when it encounters an ECC error and the unit will be setback to Degraded.Since enabling this policy could result in the loss of some source data in theevent of source errors, the default is to not enable this policy. Select thisoption only if you want to ensure that a rebuild will complete successfullywithout manual intervention. If the rebuild fails and Overwrite ECC(Continue on Source Error When Rebuilding) is not selected, then youhave the option to start another rebuild manually. After completing a rebuildwith this policy enabled, it is recommended that you execute a file systemcheck when the rebuild completes. Under Windows, you can do this by right-clicking on the Drive and choosing Properties; then on the Tools tab, clickCheck Now. Under Linux and FreeBSD use fsck /dev/sda1.
