command line issue

To restore an archive to an SSD I used this command line:
acrocmd recover disk --loc=Z:\deploy --arc=MyArc --volume=1-1 --target_disk=1 --start=1024kb --size=32gb --type=active --progress

Remark: --start=1024kb
But the partition still starts at 32KB instead of 1024KB.
The GUI works, but  I need the command line.
Any suggestions?

TIA
