Now your Raspberry Pi device will spin down your usb hard drive to save power and hopefully extend the life of your hard drive. So a value of 120 yields 10 minutes (120*5=600).Įnable write cache and spindown time by adding this text to the bottom of the file /dev/sda | sudo crontab. The spindown_time value is multiplied by 5 and you have the total time in seconds.
Time to make hdparm configurations permanent edit the configuration file sudo nano /etc/nf Values between 1 and 127 allow spinning down of the hard drive. To make hdparm spindown the device you can use the -B flag In raspbian, just change the root flag in /boot/cmdline.txt to root/dev/sdaX where X is the number of the appropriate partition. If you don't see a star (asterix) then write cache is not possible for your drive Write cache If you see a * (asterix) then you are good to go. Sudo /usr/sbin/hdparm -I /dev/sda | grep 'Write cache' If you see output like this you will need to use hd-idle or sdparm /dev/sda: You should get output like this indicating a successful standby command /dev/sda: Make sure your drive supports hd parm, if you have multiple hard drives it could be /dev/sdb or /dev/sdb – the command blkid will show you all disk drives connected.

Raspberry pi hard disk manager install#
Install hdparm sudo apt-get install hdparm -y We are going to test hdparm first as it is widely used
Raspberry pi hard disk manager update#
sudo apt-get update Install and Configure hdparm on Raspberry Pi I have just learned that the USB host adapter firmware is also upgradeable on the Pi 4. Check the power supply of the external hard disk. Also look at /var/log/syslog at around the times this is happening and see if anything is there. You can find out your device names on your Raspberry Pi, usually /dev/sda with this command sudo blkidĭo update your repository list before installing any of these programs, you only need one to work so make sure to remove the others if they are not compatible. Try: 'dmesg tail' and see if there are any hints there. If you are trying to figure out which hardware would work best for you, consider reading the Pi benchmarks. I tested these guides on Lubuntu, Raspbian and Minibian and should work on any Linux Debian/Ubuntu based system for devices like the Banana Pi, Orange Pi, Hummingboard, ODROID, Cubieboard and Hummingboard devices.
I recommend using hdparm or hd-idle and using sdparm as a last resort. I have included guides for hdparm, hd-idle and sdparm which should cover most users wanting to manage hard drive power consumption on the Raspberry Pi. We can partition/format the mSATA SSD on Raspberry Pi or other Linux PC.The OS should be based on Linux.such as debian. Which program will work for you depends on the USB to SATA controller you have and the hard drive itself. For the little Raspberry Pi and its relatives (Banana Pi, Orange Pi, Beaglebone etc) there is an array of programs that will assist you.
