I once had exactly the same problem with my Hitachi hard disk.

For me it turned out, that the culprit was the "SMART Auto Offline Data
Collection", I had turned on with the smartctl application.
With this setting active, the drive did never spin down on its own, but
stayed in standby for several minutes (using laptop-mode) after "hdparm
-y".


However, you don't mention any change you might have made in this
direction, so I don't think this is the solution for you.
Unfortunately, I don't have another idea, sorry.
