I have a Windows 2008 R2 64 bit SP1 Server running with 2 WD20EARS-00MVWB0 drives in a mirror-set.
No problem so far.
1 drive became faulty, so I orderd a new WD20EARS drive.
When it arrived, I’ve noticed that it was a WD20EARS-07MVWB0 drive.
AFAIK the last part of the code is the firmware, so it should be much of a problem.
When I replaced the faulty drive and tried to remirror the drive, I got an error in Windows saying “All disks holding extents for a given volume must have the same sector size, and the sector size must be valid.”.
I’ve tried searching for any solution on the internet, removed patch 982018, didn’t find any firmware updates to download…
Can someone please help me with this problem?
