[Trisquel-users] Re : Strange Checksum-Problem with Acer Aspire V3 772G

If you have been convinced by rms' speech, you should certainly have written  
"GNU/Linux" whenever you wrote "Linux" above:  
https://www.gnu.org/gnu/linux-and-gnu.html

Check out your disk's SMART data and self-test it. In Trisquel, you can use  
the "Disks" utility in the "System Settings". Select your disk on the  
left-hand side of the window, click on the "gear" button in the top-right  
corner and choose "SMART Data & Self-Tests...".
