My Book Thunderbolt Duo

Hi, I bought this RAID external HDD about 4 years and its run with 2 x 2tb WD caviar green disks all that time. I believe that these green disks are being discontinued and so clearly I need to replace both before one fails. Will the red, blue and black versions work in the enclosure if replaced as pairs
?? I emailed the support team but didnt get anywhere.

Hi burnie01,

Yes, all the drive would work but I would recommend you to get the WD Black drive to get the better performance.

Hi Alex

I have My Book Thunderbolt Duo 2 x 2 TB in Raid 0. I wanted to reset the drive to factory settings, there’s no reset button the drive enclosure. How does one reset the drive to factory settings? Also, I was told by someone else in WD that the only drive now supported for the My Book Thunderbolt Duo is the RED drive, is that correct or can I use the Black Drive instead?

To add some info I tried using Disc Utility to erase the drive in APFS format. The Drive is now not recognised by WD drive Utilities hence my question about resetting it to factory settings.



Hi bontfaen,

Maybe you should try contacting WD’s Technical Support about this.
