WD5000KS Post Hot Swap Problems

[Balvan]

I have a WD5000KS with bad head #1. I copied modules 31, 32, & 33 to donor drive and regenerated translator. Then I did a smart hot swap.

I can read all of the firmware modules (copy 0) with the modules table, and all are good. But DE is painfully slow and there are too many ECC errors.

I am guessing there are some other adaptive parameters that are different and which are making this difficult.

Any advice?

Spaceba,
