All data gone on My Book Studio II

I removed WD folders from Library/Application Support and all files with WD in their names from System/Library/Extensions. Finally the WD Drive Manager does not show up in the menu when I connect the formatted MyBook Studio Ed II 6TB.

BTW my Time Machine is on a 2TB single hard disk WD My Book drive and it’s working fine under Mavericks with and without the WD software. “seriously” said that his WD RED disk has not been affected but his WD GREEN disk on the same dock has been formatted to “MyBook”. I wonder if this could be a Red/Green problem as well as a RAID problem.
