MyBook Disk Replacement

Hello guys,

Yesterday I realized that one of the disks from my WD MyBook Studio stoped working. I’m looking for the drive for replacement a caviar green 3TB disk but in my country its quite difficult to find one of those.

My question is, can I use a WD BLUE disk (WD30EZRZ) instead the GREEN one (WD30EZRX) ?

Kind regards,


Page #27 of the user’s manual it says:

Important: Only WD Caviar® Green™ hard drive assemblies can be inserted into
the My Book Studio II enclosure.

Onde the green line is no loger available which line may fit to this enclousere?
