Make Load Cycle Count stop on Western Digital Green drive:(

I have a Western Digital Green WD15EADS-00P8B0. I've read that thread here and some on Synology about these drives. But it's still going up up up.

# smartctl -a /dev/sda | egrep  'Power|Start|Load' 
  4 Start_Stop_Count        0x0032   100   100   000    Old_age   Always       -       67
  9 Power_On_Hours          0x0032   098   098   000    Old_age   Always       -       1596
 12 Power_Cycle_Count       0x0032   100   100   000    Old_age   Always       -       35
192 Power-Off_Retract_Count 0x0032   200   200   000    Old_age   Always       -       15
193 Load_Cycle_Count        0x0032   183   183   000    Old_age   Always       -       51471

This thing has only been running a month or two. I can hear it clicking all the time.

I did

 
hdparm -B 255 /d/dev/sda

setting Advanced Power Management level to disabled
 HDIO_DRIVE_CMD failed: Input/output error
 HDIO_DRIVE_CMD(identify) failed: Input/output error

but it's still going up. It's gone up like ten while I've been writing this post.

Here's teh dirty expire and dirty write back things:

# cat /proc/sys/vm/dirty_expire_centisecs /proc/sys/vm/dirty_writeback_centisecs
3000
500

Have you tried 254 instead of 255?

/d/dev/sda

Wrong. Should be /dev/sda - why did you insert "/d" at the start?

The command is:
hdparm -B 255 /dev/sda

That extra d is just a typo in the forum.

I have tried 254 too.

I tried 255 and 254 again. Nothing works. Is there anything else I can modify?

Set it to 255 and left mpd playing random music off of it and Load_Cycle_Count still went up 130 in 2 hours.

Will changing  dirty_writeback_centisecs and dirty_expire_centisecs do anything maybe?
