Drives "locked" after being in NV. HELP!!!

hdc: WDC WD740GD-00FLA1, hdc: enable ATAEXT,security=7 
hde: WDC WD740GD-75FLA0, hde: enable ATAEXT,security=0 

Security value is from IDENTIFY DEVICE word 128
bit 0: Security supported?
bit 1: Security enabled?
bit 2: Security locked?
bit 3: Security frozen?
...

From the log, 1st 3rd and 4th drive are locked, 2nd drive is not locked.
This can only happen when user aborts XRAID build, because we only
lock drives for XRAID build(Initial and Expansion). Drives will be unlocked
when build finishes.

If there is no data on these disks yet, you can build XRAID
with unlocked 2nd drive first, shutdown and then and all locked drives in,
system will then erase all 3 locked drives and then unlock it.

You may unlock disk yourself, the procedure would be:
1. Unlock drive using user password first.
2. Disable password using admin password.
The passwords we use for admin and user both are:

for i=0:15
         password[i] = 0xbeef + i; // 2-byte short word
We use big-endian while Intel uses little-endian, so password
on PC may be: 0xefbe, 0xf0be, ... Sorry for picking up beef as password. 

Let me know if you have any problems. I am going to ask our software
engineers to prepare a service package to unlock drives accidentally
locked by us.
