Hi all

Yesterday I received my new 4TB WD Mybook.

As I wanted to make sure that the drive didn't have any failures, I runner HD Tuners Error scan.

No errors were found.

However, even though the scanning speed of the individual blocks started at 178MB/s, I noticed that around the middle it went to 152MB/s and towards the bottom was only 85MB/s.

Is this an issue with the disk or normal?

Many thanks
