Yesterday, a drive “unplugged” on my Synology DS-1520+, as blogged here. I ran the recommended S.M.A.R.T. Extended Test, which it told me would take 32 hours. Today I went in to check the results.
The S.M.A.R.T. results are not where you might expect them, under HDD/SDD > Logs. Rather, you need to select HDD/SSD > HDD/SSD, highlight the drive you tested, click the Health Info button, click the S.M.A.R.T. tab, then scroll down to view the Test Result:
This article also has instructions about how to view S.M.A.R.T. results from the command line using smartctl. Note that in my NAS, the disk devices are now names /dev/sata1, /dev/sata2, etc.—no longer /dev/sda, /dev/sdb… So with this command:
smartctl -a -d sat -T permissive /dev/sata2
I was able to view this in the results:
Incredibly helpful article. Thank you
