TRIM activé ou pas, Activable sans danger à postériori ?

[olrik]

Bonjour

Je viens de voir par hasard sur mon Hack numéro 4 (voir signature) que le TRIM de mon SSD n'est pas activé (dans information système) alors que j'ai bien le patch suivant dans mon config.plist

IOAHCIBlockStorage
Find : 00415050 4C452053 534400
Replace : 00000000 00000000 000000

Puis-je l'activer maintenant avec le terminal ? Mon installation fonctionne ainsi depuis 2020.

A part une sauvegarde faite quelle précaution prendre ?

Merci d'avance.
