If drives are not on the compatibility list, they will still work. Some business-targeted systems such as XS series might have a warning about compatibility though. But people have figured out how to remove this warning.
edit the /var/lib/disk-compatibility/<model>host_v7.db or <model>host.db file adding in your drives.
Enable SSH on your Synology Device
Login via SSh in your Synology Device
cd /var/lib/disk-compatibility
make a copy of the directory on your local hard drive for backup purposes
example: scp admin@YOURSYNOLOGYIP:/var/lib/disk-compatibility c:\temp
change the filename of my rs2821rp+_host_v7.db to your device model
Inside the file change "MZ7LH1T9HMLT-00005" to your Harddrives model and change "HXT7904Q" to your Harddrives firmware. Save afterwards
copy the file via scp to /tmp on your Synology Device
example: scp c:\temp\rs2821rp+_host_v7.db admin@YOURSYNOLOGYIP:/tmp/rs2821rp+_host_v7.db
overwrite the existing file via sudo cp
example: sudo cp /tmp/rs2821rp+_host_v7.db /var/lib/disk-compatibility/rs2821rp+_host_v7.db
reboot your Synology Device
Check your Harddisk Status
If it won't work
copy the files eunit_rule.db and host_rule.db over the existing files on your Synology Device.
Reboot your Synology Device
Check your Harddisk Status
