Test to see if your Synology NAS is using 4k sectors

Login using SSH/Telnet as 'root' with the admin user password and run the following command.

'fdisk -lu'

The first partition should start at 256, not 63 as shown in my example.

You'll need a clean install of DSM in order to have the Diskstation automatically format your dives using the 4k advanced format. More info on data migration on the Synology website here.
