I made a second test. I added
// hdd cache read test
at the end of the main loop at powermgm.c, so that code is called once
I leaved the unit on without playing a mp3 file.
Result: every minute, the hdd spins up and reads the same sector
again. :-( Now i'm pretty sure that the hdd internal cache is not used
Could it be that one can enable/disable the cache of such a harddrive?
