I never replaced the PSU. Instead I put the drive into an external USB enclosure and the problem has disappeared. Western Digital was no help in finding a reason for this issue.


It could still be a PSU issue then, since the drive now has it's own separete external PSU, and the problem went away... Maybe WD is more sensitive to power fluctuations than other drive brands are.

But anyway, glad to read you've found a satisfactory solution.
