The drives read-ahead mechanism is usually better than our write buffering. Even when the drive has its write-cache enabled, there is a difference. Also, with just writing you will never know wether there was a parity error and by writing the full disk (or parity blocks) you may cause additional errors. -- -- Michael van Elst Internet: mlel...@serpens.de "A potential Snark may lurk in every tree."
