How to check WD My Book World Edition disk temperature?

Normal MBWE WD Caviar Green HDD temperature should fit in range 38-50°C. We can simply use S.M.A.R.T. monitoring hard drive feature to read current temperature using few commands.

Solution

To read MBWE hard disk temperature do the following steps:

  1. Enable SSH on your MBWE. To do this, login to your MBWE web interface and go to Advanced Setup > System > Advanced then check SSH Access to Enable and click Submit.
  2. Open Terminal on your Linux/MAC OSX (for Windows use PuTTY or simple boot Ubuntu Live CD) then write following command, providing your MBWE current IP address (here is an example):
    ssh root@192.168.1.2 [hit ENTER]
    and provide password:
    welc0me [hit ENTER].
  3. Write the following command in Terminal after login to SSH MBWE is done:
    smartctl -d ata -A /dev/sda [hit ENTER]
  4. Read your disk temperature on 194 position, column RAW_VALUE (see Teminal window below). If you want read temperature of second disk (sdb) in MBWE II, then write command:
    smartctl -d ata -A /dev/sdb [hit ENTER]
  5. Disable SSH on your MBWE as shown in step 1 when you finished.
  6. Done.
