That is certainly right. I just wanted to tell you, that your /dev/hde
probably has a serious hardware error, and that you should replace it!

Of course you can just throw it out, put in a new drive, rebuild the
array with your other drive and the new one, and then resync. This
should work just fine.

I guess my first answer was quite confusing, sorry. It's absolutely not
necessary to copy the old hde with dd_rescue.
