Well put - I should have read your message before responding. However: > ... Since we don't do read after write verify operations if > a data hard error occurs in the block during the write that is undeteced > during the read there is nothing that AWRE/ARRE can do about it... Do think this happens often? Are there situations where "write and verify" support would be worth the probable huge performance hit? -- Peter Dufault Real-Time Machine Control and Simulation HD Associates, Inc.
