I have an nvme drive with a logical and physical sector size of 4096.
The block size of this drive as reported by blockdev --getbsz
command to be 4096 as well.
The destination drive is an SSD with a logical and physical sector size of 512. The block size of this drive is 4096.
I tried using dd with the next parameters to clone the drive:
dd if=/dev/sda of=/dev/sdb
but the only partition that i am getting is GPT partition.
I also tried cloning the GPT table with those commands:
sgdisk
and
sfdisk
but no luck there. i am getting a drive with a partition table that every partition is 8 times smaller than the partition in the original drive.
Do you have any suggestions?
dd
the individual partitions separately. However, filesystem internal structures might still cause issues with this operation.
