Constant flashing white light?! UPDATE : Now flashing yellow

Hi,

I have an 4 year old MyCloud (4TB), which now just stays on flashing white light… it will sometimes hop to blue, but then reverts back.

UPDATE : Now flashing yellow!

I can not connect to the device at all (i have changed ports on my hub, tried different cables, and even direct connection). I have tried soft and hard restarts, no fix.

Does anyone have any ideas?

Side note : If it is dead, will the drive be readable by MacOS or do i need to linux up?

the hard drive file system format is EXT4 which is Linux
