Hi Paul,

thanks fopr your help.

When I submit a

    sudo hdparm -B /dev/sda
    
I get back:

/dev/sda:
 APM_level      = not supported


when I do a 

    sudo hdparm -B 254 /dev/sda

I get back

    /dev/sda:
     setting Advanced Power Management level to 0xfe (254)
     HDIO_DRIVE_CMD failed: Input/output error
     APM_level      = not supported

so I think I loose the game.

Or did you use other options?

Best regards,
mcc
