Hello, We have some old system (2.4 kernel) which use hot swap with sata (IDE) , bu using commands such as: hdparm -U 0 hdparm -R 0 0x1f0 ... But in newer system HW&SW we never use these commands when removing and inserting sata. Why was it used once and why is it not used in newer system ? Is it that newer system do this somehow automatically ? Where ?is it done, in SW or HW ?
