Archlabs booting from SSD in caddy but (unmounted) internal HDD still being accessed? (noises)

I boot the T410s from the sdb SSD in the caddy, and have confirmed that (got the below from here)

leigh@T410s / % lsblk -r | grep '/boot'
sdb1 8:17 0 512M 0 part /boot
leigh@T410s / % lsblk -r | grep '/$' 
sdb2 8:18 0 223.1G 0 part /
leigh@T410s / % awk '$2=="/"{print $1}' /proc/mounts

The internal HDD is sda, and its not mounted at all (I can see this in Thunar)

All is working fine, but I cannot understand why I can still hear the internal HDD being accessed (the HDD type noises coming from where the HDD is). SSD’s are silent as far as I know.

Can anyone suggest a reason please?

polite things, preferably.

I know I dont need to know, but its bugging me

thunar does volume management AKA reading any drive, have you looked into that?

sounds to me like thunar is just getting excited and “mounting” stuff. Even if it’s not setup to automount it would make spinning plates get warm for the order to be mounted somewhere.

Thanks @cog

I do have Thunar volume management selected
But I didn’t have thunar-volman installed (is this just to access settings or is it needed for vol management?

Strangely, the HDD noises have now stopped
I will try later on next reboot with this unenabled, or even disabled

Could it be anything to do with the integrated Intel graphics card ?
Memory allocation being low and then it access the HDD when this is exceeded?
I did notice that it was being accessed as I pageupped and downed through a long Joplin note
But its stopped accessing it now,

not having volman installed kind of negates my ideas. but even the kernel would spin up the disk. dmesg

you can’t just go around sharing strange disks with T16s and women in lakes with swords and expect something not to happen


Its definitely being accessed not just spun up, you know, that scratchy sounding disc sound
Opening up Firefox set it off

That film is pure genius
when I was in the archetypal student house, there was obviously no internet then (we did have electricity when we had enough coins for the meter tho) and we had no TV aerial, and only one VHS cassette - but it was The Holy Grail.

And then, impossibly, they made something just as good

what am I looking for there, please?

I took out sda HDD and it booted fine
But that noise was till there
No idea what it is, it is definitely a sporadic sound like that when an HDD is read/writing (high speed clicky/clacking) its not a rotational noise, but does seem to be coming from same area as caddy
But the only disk in there now is the SSD in the caddy

the SSD is a cheap blueray ultra m8s
I cant find much info on it
this ‘brand’ seems to be only available in PT

Maybe its this?

Definately not an SSHD
