I have recently bought new WD hard driver.
Like in subject it is new driver with 4K sector size.
First of all WD had writen on hardware that this disk doesn’t need any preparation in other system then WIndows XP.
I am using Linux and this statement is false and wrong. This model needs preparation before installing Linux on it.
Without preparation performance is very low.
Secondly I have noticed recently that Load_Cycle_Count from smart is raising rapidly (10 points in 20 minutes).
I read that it shouldn’t raise more then 2 points in one hour.
I tried executing command: hdparm -B 254 /dev/sda
but it shows:
setting Advanced Power Management level to 0xfe (254)
HDIO_DRIVE_CMD failed: Input/output error
APM_level = not supported
This command should turn of power saving and solve problem with Load_Cycle_Count.
What is wrong with this driver.
With this progress of Load_Cycle_Count in smart I will need new hard driver sooner then I expected.
With old driver I didn’t have those problems.
