However, it will not work because the FreeBSD version will not skip over the bad sector on the source drive. I am not sure if I would want this feature in the first place as I would like to know where my corrupted data is. If both my drives are physically degraded, I would look to restore from backups instead. >Also, the lack of support for the current firmware on the 7000 series >cards makes me hesitant to use those cards with FreeBSD. What specifically does not work with that firmware ? ---Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
