Hello,

I'm about t replace a harddrive (more space needed)
So while looking around I noticed the following..
I have two drives in my as6102.. drive one a 4tb WD red.. and in the second slot.. a seagate barracude 1 TB.. which I'm about to replace..

But I noticed that the barracuda shows a running temperature for the drive.. while the wd doesn't. I never looked at this. Before but it strikes me as odd. I never have had any problems with the drive.. could this still be a failure? Or is it normal for a wd red of 4tb..

I tried to look at specs.. but can't seem to find if it should or shouldn't display temp readings.

Any suggestions would be appreciated!

I'm surprised. I can always read disk temperature. You can go to ADM web -> Storage Manager -> Disk -> select WD disk -> SMART Info. Did you see ID=194? That's temperature record of this disk.

i checked what you suggested...
smart info: completely empty field. on the other hand for the other disk (already, showing the temp) shows a full list of (smart) data.
Smart scan (full): no error found.. guess it has something to do with smart not being on? although the status is good, and status is healthy

i also rebooted and checked the uefi / bios.. but for 1 i didn't see a reference to s.m.a.r.t as such.. but did find no difference in settings for both drives.
als on boot it clearly stated s.m.a.r.t. enabled. but no reference to a specific drive.
and ofcourse some part is indeed enabled as the 2e slot drive's smart capabilities work great.

SMART info is generated by HDD itself. So it's surprised that this HDD don't provide ID-194 SMART info.

i figured out how to solve it..

i took the drive and connected it externally to my ubuntu laptop.
installed smartmontools:
# sudo apt-get install smartmontools

ran:
# sudo smartctl -i /dev/sdb

to check the drive's info, including smart.

apparently the smart functions can be turned on and off! didn't know either but some googling led me there.

running:
#sudo smartctl -s on /dev/sdb

turned the smart functionality on..

why it wasn't on from the start is somewhat of a mystery to me but it got solved.
hope this will help others.

ps: sdb is just my drive's name, please check you run this on the correct drive on your system for your self!

Wow, I didn't know that. Thanks for sharing.

my pleasure..

i ask a lot,, but once i find stuff out that could be intreresting to all, i try to share.

Just in case somebody had similar issue, you can install smartctl commandline tool on NAS too. It is available through entware-ng package from App Central.
After installing it you can connect through ssh and launch:
opkg update; opkg install smartmontools
