I tried this with a drive that had been faulted out of an array. I ran "fsck 
-c -c" on it before I ran "raidhotadd". The drive is one that I has given 
trouble in the past.

It took a long time for the "fsck" to completed (about 24 hours) but the 
drive might not have had dma active at the time.

In this instance it did not help. The drive has faulted out again after 
about a weeks operation. It seems this device is on a slow inevitable 
slide to total failure. I have done a "raidhotadd" again, but I think I 
must organize a new drive.
