I am a noob, but it looks like either the drive is not of the right type (BEVS) or you may have something going on with your sata chipset. Make sure it is set to legacy and then try it again.
I found this here:
HDDHackr v1.25 Build 20101114
People with misflashed hard drives should try out the following:
* Vendor Intro Power Brute for misflashed drives *
To enter the recovery mode you should boot to MS-DOS, connect your hard drive to PC and type
'HDDHACKR R [PORT] A0 UNDO.BIN'. If the hard drive is misflashed you will be prompted with:
"Western Digital Vendor Intro failed on port [PORT]"
"Do you want to resend the command until the drive responds (Y/N)?"
Press YES, disconnect the hard drive from power and connect it again.
You should get Status 0x50 and the drive will be reflashed.
