I'll receive my first NAS (a Synology DS413) and three hard disks tomorrow. Of course I'd like to check if everything's fine with the disks before setting up RAID and migrating my data. Unfortunately, I don't have a PC to put them in; I've got only notebooks.

Can I somehow do this with the NAS firmware? And what kind of tests should I run, apart from S.M.A.R.T.?

There are really no other tests other then S.M.A.R.T you can run. You are at the mercy of the HDD knowing its going to fail before it actually fails. Synology provides software to verify the interity of the raid. S.M.A.R.T is not guaranteed to catch anything. It won't catch a mechanical problem for instance. – Ramhound Jul 16 '13 at 15:38

The Storage Manager will show the SMART status of each disk. Log into the web interface and go to Main Menu > Storage Manager > HDD Management.

HDD Management Screen

You can also schedule a more in-depth SMART test using the Test Scheduler Option on this screen.

As Daxlerod has stated you should use the SMART tools, however you also need to perform what is called data scrubbing.

If you haven't already, create a disk group. For data scrubbing to be available you need at least 3 disks, with at least 1 redundant drive and at least 2 data drives. Wait for the disk group to fully synchronise, then perform a data scrub.

As of Synology OS v4.2 data scrubbing can be accessed from

Storage Manager -> Disk Group -> Manage -> Start data scrubbing

This will take hours as it reads all sectors of all of the disks and performs some math to see if the checksum data adds up properly. You can use you NAS while this is going but it will be a bit slower. Many people run a data scrub once a month.

There is a good article called Scrub Synology RAID disks that also tells you how to run the file system check tool called fsck even though there is no option in the web interface for it.
