I have a MyBook Duo 4TB that I’ve changed the raid to 1. Model number is WDBLWE0080JCH-00.
When my Windows 7 computer is reading or writing I hear a noise (not a clicking sound) as it’s being accessed. The Drive Utilities is reporting everything is ok but I’d like to confirm that the sound I’m hearing is normal for these drives.
I have an SSD and a WD slave drive on my my computer and can’t hear Hdd drive activity but that may be because it is internal and different model of drive.
Better safe than sorry to ask.
