ssdnow s100 ext4 trim not working
 

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.

The link you provided is bad.

Just fixed the link.
Thanks

any luck? having the same issue, drive supports trim, on the latest firmware, ahci mode, mounted with discard option...but automatic trim not working.
