Is this "short while" in the middle of an active session, or have you
suspended/hibernated/rebooted/powered-down, in the meantime?
No, I've been through all those issues.
The system is live, and hasn't even timed-out an turned off the screen.
You may need to look into your power-management settings, and make
that any wake-up/thaw events reprogram the setting. I had to do that
I've looked into those, and haven't found anything related.

Try a different value, such as 254, instead.
That was the second thing I tried, all to no avail.
Its as if the drive ignores whatever hdparm does.
I also just tried (with no success)
hdparm -S 0 /dev/sda
