By the look of the command you posted it’s from an old version of the iceman firmware. Make sure you are running latest.
Here’s how it goes.
Hf mf wrbl -k (key used for writing the block, default is FFFFFFFFFFFF) -b 0 (specifying block to write) -d (data to write, this is where you put the block 0 data you wish to write onto the card)
E2A: when you’re on latest the command you’re looking for the rest of the data & optionally to also write the uid block is hf mf restore -h
