I have the same problem, except that I'm running Ubuntu 12.10. The disk in question is Hitachi HDT721010SLA360 connected to ASUS P8H77-I motherboard. The disk goes to standby with hdparm -y , but hdparm -S 1 (or any other number I tried) has no effect. I have a feeling that this might be related to having the system configured in BIOS to AHCI mode instead of PATA, but I haven't examined that further.
