Hello again I've formatted my SSD using ext4 and enabled TRIM using the "discard" option. Then i've run that test https://sites.google.com/site/lightrush/random-1/checkiftrimonext4isenabledandworking and it failed : no TRIM with that configuration. Since it's theorically possible to get TRIM without AHCI, only using 48-bit LBA addressing, do you know if a can find a driver that would enable TRIM ? thanks in advance Thibaut France 2011/9/14 thibaut bethune <thibaut.bethune@xxxxxxxxx>: > Hello, > > I'd like to know if my system is ATA TRIM compatible : > > 1°) I've just bought a SATA SSD (Crucial M4) which handles TRIM > 2°) I'm running Linux 2.6.33 whch also handles TRIM (ext4 + "discard" option) > 3°) My motherboard (ASRock Conroe 1333 DVI/H R2.02, featuring the ICH7 > southbridge) doesn't handle AHCI.
