Synology NAS

With any new hard drive you receive, disk break-in is necessary to ensure that the drive is fit to hold data. The process is no different, but finding the right disk path is.

You can run

 fdisk -l 

which will output a lot of mounts.. which in the case of the DS220+ I own, isn't much in theory. But, after a lot of trial and error, I have found that /dev/sata is the correct mounts to reference for full access to the disk. To list those disks in your NAS, run

 fdisk -l | grep /dev/sata 

Note, that due to how Synology utilizes a disk to get the OS functional to use, you won't be able to break in all the drives at once. If you have a spare drive you can toss in, that might help so that the OS can stay functional. The commands do not eat up a lot of RAM, so they can be run simultaneously. The disk can not be in use with the NAS.

smartctl on Synology requires the use of the -d option to force it to specific disk modes. In our case, this will be SATA, so '-d sat' is used.

## List disk
smartctl -d sat -a /dev/sata1
## Short Test
smartctl -d sat -t short /dev/sata1
## Long Test
smartctl -d sat -t long /dev/sata1
## Badblocks (will take several days, if not a week depending on disk size due to running five passes)
## Destructive
badblocks -b 4096 -wsv /dev/sata1
## Non-destructive
badblocks -b 4096 -nsv /dev/sata1
