    External hard disk spins all time.

    My 2TB WD external hard disk spins all time while it is plugged in even when I don't save/backup. Is it normal ?

    Does your external hard disk have a programmable shutoff?

    With hdparm software you can try

    sudo hdparm -S 1 # to standby after 1 minutes idle.
    sudo hdparm -S 6 # to standby after 30 minutes of idle Each -S unit represents 5 minutes

    Note it is a capital -S and not a lower case -s

    man hdparm
    messsage: hdparm [options] [device ...]

    Options:
    -a Get/set fs readahead
    -A Get/set the drive look-ahead flag (0/1)
    -b Get/set bus state (0 == off, 1 == on, 2 == tristate)
    -B Set Advanced Power Management setting (1-255)
    -c Get/set IDE 32-bit IO setting
    -C Check drive power mode status
    -d Get/set using_dma flag
    -D Enable/disable drive defect management
    -E Set cd/dvd drive speed
    -f Flush buffer cache for device on exit
    -F Flush drive write cache
    -g Display drive geometry
    -h Display terse usage information
    -H Read temperature from drive (Hitachi only)
    -i Display drive identification
    -I Detailed/current information directly from drive
    -J Get/set Western DIgital "Idle3" timeout for a WDC "Green" drive (DANGEROUS)
    -k Get/set keep_settings_over_reset flag (0/1)
    -K Set drive keep_features_over_reset flag (0/1)
    -L Set drive doorlock (0/1) (removable harddisks only)
    -m Get/set multiple sector count
    -M Get/set acoustic management (0-254, 128: quiet, 254: fast)
    -n Get/set ignore-write-errors flag (0/1)
    -N Get/set max visible number of sectors (HPA) (VERY DANGEROUS)
    -p Set PIO mode on IDE interface chipset (0,1,2,3,4,...)
    -P Set drive prefetch count
    -q Change next setting quietly
    -Q Get/set DMA queue_depth (if supported)
    -r Get/set device readonly flag (DANGEROUS to set)
    -R Get/set device write-read-verify flag
    -s Set power-up in standby flag (0/1) (DANGEROUS)
    -S Set standby (spindown) timeout
    -t Perform device read timings
    -T Perform cache read timings
    -u Get/set unmaskirq flag (0/1)
    -U Obsolete
    -v Use defaults; same as -acdgkmur for IDE drives
    -V Display program version and exit immediately
    -w Perform device reset (DANGEROUS)
    -W Get/set drive write-caching flag (0/1)
    -x Obsolete
    -X Set IDE xfer mode (DANGEROUS)
    -y Put drive in standby mode
    -Y Put drive to sleep
    -z Re-read partition table
    -Z Disable Seagate auto-powersaving mode

    Using hdparm -S 6 /dev/sdc #or whatever your drive is. Check the drive after 5 minutes.

    Note, if you issue a find or some task that needs to read each disk, the drive will restart to satisfy that read.
    It will of course return to Sleep thereafter based on the initial the -S timeout value
