What controllers did you test with ?
Tested with my own Crucial CT128M225 model which has the IndiLinx

Oh I see, I have an Intel DP35DP motherboard with onboard IDE controller
with AHCI enabled. I hope thats sufficient information for now. I did read

would disable for all drives connected.

Please let me know if further info/log files (dmesg, lspci etc) would help
and I will pastebin them...

Can you identify the specific Indilinx build number that your drive firmware
is based upon? If not, then at least post the identify data for us to examine:

hdparm --Istdout /dev/sd?
