They correctly report NO SCT ERC ability (unlike WDxxEADS from November 2009 on). Trying the commands nevertheless results in "command aborted". So my recommendation would be: if you need a fast large array and want to use WD, keep enough redundancy and a cold spare. (Respectively because I returned 2 drives to Western Digital today, too. They had reallocated and pending sectors >100 and already dropped out of RAIDs.) Or use Hitachi deskstar HDS722020ALA330 - these can set ERC timeouts and they cost about the same. We have sold about 10 times as many Hitachis compared to WDs, but had about the same amount of defective drives. All the best, Stefan
