I can't get the trim working on this ssd although it is supported on ext4 fs from kernel 2.6.33 onwards.
I have tried with ubuntu maverick 32 bit and the discard option, AHCI enabled in the bios too but with no success. ( device is a Zotac ZBOXHD-ND22-B )
To test whether or not the trim is working I am using the dd test you can find in here http://sites.google.com/site/lightru...bledandworking
I have tried to:
Using different kernels/os versions ( ubuntu natty narwhal )
enable/disable AHCI DID linux in the bios
enable/disable AHCI in the bios
enable/disable SATA mode in the bios
But I keep getting the same sequence of letters/numbers, instead of zeroes.
