"Active/passive means that one controller is active to process I/O requests, while the other is idle in standby mode ready to take over I/O activity should the active primary controller fail or be taken offline.
An active/active configuration enables both controller nodes to process I/Os, and provide a standby capability for the other."

windows dd usage
Show you how to clone usb disk first 100MB
suppose your usb disk is drive number 1 (check windows "Disk management" and find out its number)
dd if=\\.\PhysicalDrive1 of=sdb.dd bs=1M count=100
But this windows dd's writing to disk is very SLOW.
