I tried to reboot, but unfortunately the system paniced (something about a flush-cache not finishing). After rebooting, I started a dd if=/dev/zero bs=32k of=/dev/wd4dNo. rwd4d.
Ooopppsss!Yeah, it works much better on the raw device. After 10 minutes, the rate has remained constant at 100MBytes/sec. And I can even run a second dd on the other prospective raid member and they _both_ run at 100MByte/sec.
At this rate it will take about 1.5 hours to zero the entirety of both drives, then I can start reassembling the raidset.
