Someone actually buttonholed a Seagate engineer a couple of years back and he said with absolute certainty that a Seagate drive would lose up to two sectors, but not more then that. I've had direct experience with this. Seagate drives will indeed lose up to two sectors if you are writing during a power loss... and this is *GOOD* for the industry. Quantum drives (more direct experience on my part) have been known to lose whole tracks and even multiple tracks. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
