That's good news. Have you tried seeing if you can run the manufacturers SSD monitoring app on your machine?

I have had another look at mine. I have 2 SSDs, both M.2 drives so I would expect your 2.5" SATA drive to run a bit cooler. The System disk, a 500GB Western Digital Black, ticks over at 44°C. The Data disk, a 1TB Crucial one is at 36°C.

@Baldrick1  Sorry for delay.... no, I have not !. don`t know anything about that.

Try installing package gsmartcontrol.

GSmartControl is a graphical user interface for smartctl, which is a tool for
querying and controlling SMART (Self-Monitoring, Analysis, and Reporting
Technology) data on modern hard disk drives. It allows you to inspect the
drive's SMART data to determine its health, as well as run various tests on it.

Well.... that was a load of fun !

After the "install"   ( sudo apt install gsmartcontrol )

gerry@gerry-GL752VW:~$ gsmartcontrol

@shutter You don’t need that package. Just use “Disks” from the control centre. Select the drive on the left and click the three dot button top right (top bar, middle right really) and select SMART tests and info.

gsmartcontrol is intended to work in a GUI environment - which it does (at least for me).

@RPMozley  Thanks for that....  looks like the 250GB ssd is doing ok !   running this one to make sure I haven`t missed something in the re-install/transfer of files and folders, before replacing it with the original 2TB SSD, and then cloning the 250GB to it.
