[gentoo-user] Cleaning the SSD

[Alain Didierjean]

Just about to install gentoo on a used SSD (Samsung SSD 840 120G). 
How to proceed to get a clean, like new SSD ?
Could the --security-erase or --security-erase-enhanced hdparm options do the job or should I use something more sophisticated (or more efficient) ?

Hi,

Have you looked at https://wiki.gentoo.org/wiki/SSD ?

I suppose what exactly you are asking for, is to make new filesystems on
your SSD, mount them and then do "fstrim <mountpoint>". But the article
suggests to run that regularly rather than once.

Hope that helps.
