Trying to mirror a volume

Question

I originally had my HD mirrored to another one, but then it said the plex was missing, so I took it out and checked it and it was dead. So i bought a 2TB SSHD to replace it. But now it's not letting me mirror it, coming up with this error: "All disks holding extents for a given volume must have the same sector size, and the sector size must be valid." So I checked the sector sizes:

And the physical sector sizes are both the same, so I don't understand why it's not letting me do it. The other disk is a 1TB SSD and I'm using Windows 10.

Answer 1

I have encountered similar problem last night and it took me an hour to find the solution. Short answer: the information given by fsutil might not be accurate.

My home server is running Server 2012R2 on an Intel 320 SSD. I wanted to mirror the drive with a new bought Intel S3500 SSD. Same error occurred and fsutil told me the physical sector size of the two drives are both 512 bytes. MSInfo and chkdsk reported 512-byte sector size as well.

I downloaded Intel SSD Data Center Tool and it told me a different story: the S3500 drive had a physical sector size of 4096 bytes. I toggled the sector size to 512 bytes with the same tool and restarted the computer. Problem solved. I also did a benchmark with HDTune Pro and didn't find any significant gain or loss in terms of random read performance before and after the switch.
