Fixing IC errros

Hello

Can anyone be nice and show me an example of IC error fix.

I read about fixing IC errors using DSE but I want to be sure  before
I start.

Here is the IC report:

I understand (I hope) that I must fix the "Block incorrectly marked
busy" error before I fix (if it will remain) the "local bit map
incorrect" error.
So how I switch the BUSY block to FREE block using DSE.

Thanks in advance.
