SEAtools isnt going to detect any drives because its for SEAgate drives and you have a Western Digital...
WD uses Data Lifeguard:http://support.wdc.com/product/download.asp?groupid=613&lang=en
Also don't forget to update you motherbds' Bios:http://www.asrock.com/mb/Intel/Z75%20Pro3/?cat=Download&os=BIOS
Thanks for the response. Couple questions before I move forward:
I was under the impression that SeaTools might work as a general diagnostic test, but if that's not the case I can certainly give Data Lifeguard a shot. Is it possible to make a Data Lifeguard boot disc? SeaTools was an .iso file, but Data Lifeguard appears to just be a zipped .exe file. Will that still work?
Likewise, I'll try updating the mobo bios as well.
