When should this be done?

I have 2.6.1 + the 2.6.1-specific patches + core patches. It suspends
without difficulty, but on boot, it says it couldn't read a part
of the resume data (a "chunk", iirc). The status bar doesn't make
much progress.

I tried hdparm -W 0 right before the call to hibernate (in a script).
But I still have the problem.

When should hdparm be called?

Thanks!
