paired 2 WD 1TB win7u hdd = "FW status recovery error" after ASUS logo

I tried creating a new Win7u install on a second Western Digital 1TB hard drive, because the first drive was taking forever to settle down after entering Windows 7. Win7u was installed on the first drive in mid 2013.
I wanted the new Win7 to boot the system, while the old Win7 drive would be used only for the data it contained.
A single phrase "FW status recovery error" appeared on an all-black screen after the ASUS logo (with press Del or F2 to enter setup) when booting up. The old Win7 was the boot disk, while the new Win7 was the data disk, the reverse of what I wanted.
I had answered Yes to a question that was asked upon the previous boot up. (No longer remember the terms, could have taken a snapshot of the screen with my cell, but was too tired to think straight.)
(This error probably is the cause of the appearance of this phrase.)
I've researched this topic. "FW" would seem to mean 'FirmWare'. The topic would be 'FirmWare status recovery error'. The firmware would be related to the two identical hard drives. But to which one?
I have since succeeded in booting up with the new one being the starting drive, and the old one the data only drive. But the phrase still shows up after the logo.
I removed the 3V lithium battery on the motherboard yesterday, and did a Clear RTC RAM on the motherboard, then replaced the battery. The phrase remained after the Asus logo.
I reflashed the BIOS with the original 0707 version today using EZ Flash 2, and the phrase did not go away. I then reflashed it successfully using the 1105 version of the bios, and the phrase appears again after the logo.
Does this make any sense to you?
Do these hard drives contain firmware?
And can this firmware be repaired or reinstalled in some way?
The new Win7 installation is fast and nimble. It does not appear to have any major problems.
Removing the phrase is the only issue.

Welcome to the forum. Was the old drive cloned and did you leave the old drive in when you installed as its possible it put boot files on it. Post a screenshot from disk manager showing the disks with full details

The old drive was disconnected entirely when I installed the new drive. The new drive had Win7 installed back in 2013 as well, because of problems with the initial drive. They were solved, so it lay unused and unconnected until the old drive began slowing down on startup.

Then I disconnected the old drive, went into Win7 with the new drive alone, and began the updating process. I also installed my most useful programs. It is not fully installed yet.


Next I began the pairing process.

As to Disk Manager, I stlll have the contents of my old copies of Ontrack Disk Manager software 7.03 for Fujitsu and Quantum drives circa 1995 using MS-DOS originally on 1.44MB disquettes. The contents could be copied to a usb key or dvd.

There is also an Ontrack Western Digital version for Windows 95 circa 1997 on the web.

I don't think they could handle 1TB drives. Could they?

Can you provide a link to a modern equivalent that uses the same name? To the specific software you have in mind?

Disk managment in win 7 I ment what do you mean Next I began the pairing process?

Thank you, Samuria. I found Disk Management in Windows 7, and took a screen shot. The file is attached.
