Solution 3: Using FreeAgent software provided by Seagate
You should connect the hard drive to a Windows host and install the FreeAgent tool. Then change the auto spindown time to "nerver". You can also turn down the light of the drive, which cannot be done under linux.
Seagate FreeAgent drive auto spindown under Linux solutions
I bought a Seagate FreeAgent Pro hard drive, but find it doesn't work well under Linux. After some investigation, I find the following solutions.
Solution 1: Turn off the auto spindown/spinup ability of external drive.
# sdparm -a /dev/sdb /dev/sdb: Seagate FreeAgent Pro 400A Power condition mode page: IDLE 0 [cha: n, def: 0, sav: 0] STANDBY 1 [cha: y, def: 1, sav: 1] ICT 0 [cha: n, def: 0, sav: 0] SCT 9000 [cha: y, def:9000, sav:9000] # sdparm --clear STANDBY -6 /dev/sdb # sdparm -a /dev/sdb /dev/sdb: Seagate FreeAgent Pro 400A Power condition mode page: IDLE 0 [cha: n, def: 0, sav: 0] STANDBY 0 [cha: n, def: 1, sav: 0] ICT 0 [cha: n, def: 0, sav: 0] SCT 0 [cha: n, def:9000, sav: 0]To restore the default value:
To change the default standby condition timer to 1 hour:
