>Description:
When FreeBSD kernel writes to the RAID array (in my case - HPT370, RAID0, /dev/ar0) looks like it tries only one write operation and, in case of failure, it complains about error (ar0 - broken array). After that it's nearly impossible to recover my RAID array. It would be much better if kernel first retry a write operation at least three or more times and only then give up. Looks like it was so in FreeBSD 5.2.1 but somewhy it has changed in FreeBSD 5.3
>How-To-Repeat:
Sample: ataidle -S 1 2 0 (disk in raid0) or more.
