Cluster sizes don't matter, because a CLONE (or backup and restore) will make the clusters the same on the destination. SECTOR or block size is a different issue. If the two drives are not the same, virtually no cloning or backup software will work. (I.e., if one is 512-byte sectors and the other is 4K-native.) I only found one software, Casper, that would clone or make a backup and restore between the two sizes. I really don't understand WHY this is an issue, since most of the time this software is just copying data files, not bit-for-bit copying.Yes I can still install on the old drive and get into windows effortlessly. The new ssd also shows up in MyPc and is fully functional apart from the booting.
I want to give Macrium Reflect image restore a try tomorrow. I tried cloning it but I got an error because of different cluster sizes.
Because of this, pretty much all consumer drives, including the SN770 and SN850X (at least mine from last year) comes with 512-byte emulation enabled, even though the drive itself is physically 4K. I wanted to get the benefits (slight) of using 4K-native, and the only way to change it is sending SCSI/NVMe commands from an OS that supports it (Linux) so I had to do a Live USB boot to change it. Then cloning from my old SSD with 512-byte physical sectors to the SN850X meant finally having to use Casper. But I still had some boot issues.
This shouldn't be a problem if you're doing a fresh install. But maybe the software you tried did a clone anyway, but can't properly create the boot configuration due to the sector size difference, if in fact there is one?
Run this command in an elevated command prompt for the old and new drives (replace c: with whatever drive letter).
Code:
fsutil fsinfo ntfsinfo c:
You'll see a section like this:
Bytes Per Sector : 4096
Bytes Per Physical Sector : 4096
Bytes Per Cluster : 4096
What does yours show for each drive? (Unfortunately I found this is not 100% accurate on every drive.)
