1TB MyBook Studio firmwire 3.2.4.4. for Mac oS X Mavericks won't find the drive

I followed the instructions on this page:

http://www.wd.com/wdproducts/wdsmartwareupdate/firmware.asp?id=wdfMB_Studio&os=MAC

It had no trouble finding my drive. Wish it hadn’t. To give you an update I have scanned my drive with ‘iSkysoft Data Recovery’, ‘Data Rescue 3’, ‘Remo Recover’, ‘Testdisk’ and ‘Photorec’. Where there was once 1400GB of RAW photographic files absolutely nothing remains. Not 1 single image. All because of this Firmware that you are trying to install. Lots of cases on this forum of drives dying from firmware updates…

Good luck.
