Other Trim the entire SSD from FreeBSD's LiveCD?

[Athian]

Recently I bought one, and while playing with reinstalling distributions I wonder if I can TRIM the entire SSD using Live tools? Or I am mistaking something?

EDIT: To make it clean and faster. Again, am I missing something?

This should work for SATA SSD: camcontrol security -s qqq -e qqq -y adaX.

 

[Athian]

It does not work.
camcontrol(8) reports:

ATA_SECURITY_SET_PASSWORD_FAILED: 0.

The one Linux-based distribution I found, PartedMagic, fails too.

The SSD model is Crucial CT250BX100SSD1, part of the BX100 series.

Can I just erase all the data, install an OS, and wait faithfully that it will trim the drive for me?

 

[mav@]

If file system of the OS supports TRIM, then it should erase new disk. For UFS that should be explicitly specifies with '-E' parameter to newfs. ZFS does it automatically if it sees device supporting TRIM.

From my understanding the newfs -E is to delete the content of the disk. Adding the parameter -t should enable trim. See newfs(8).
Dear Athian, please have a look at http://www.wonkity.com/~wblock/docs/html/ssd.html and do not miss the other articles. If you are in doubt do not follow my suggestions since I am a newcomer. Better ask again to be sure . For myself the link above was very helpful.
