So I should add thisOnce there are no errors, reboot machine: 

Save and exit nano If all drives mounted successfully, it should look something like this (CTRL-X, Y, ENTERUbuntu), and try your new mount:

mount e2fsck -a<brcn />ls /var/hda/files/drivesdev/'''sdb1'''

That last command should show you the content of you new hard driveAnswer ''yes''.The <code>-cn</code> option we're using can safely be used on mounted file systems.==Spin Down Hard Drives==

That's itLow power is a good thing to have in servers. Your share(s) are now on If you do not use your new server very often, you may want to force the hard drivedrives to spin down faster than the default. Here is how.

FirstTo force to spin down after 10 minutes of being idle, you'll need add these lines to make the mount permanent<code>/etc/rc. [[Open Terminal as root|In a Terminal, as root]], type the following commandlocal</code>:<pre># power drives down after 10 minutes idle/sbin/hdparm -S120 /dev/sda/sbin/hdparm -S120 /dev/sdb...</pre>

<div style=Most drives will power down on their own without doing this. Once stopped, the drive may take as long as 30 seconds to respond to a subsequent disk access, though most drives are much quicker. The encoding of the -S timeout value is somewhat peculiar. A value of zero means "timeouts are disabled"border: 1px solid #A3B1BF; padding: the device will not automatically enter standby mode. Values from 1 to 240 specify multiples of 5 seconds, yielding timeouts from 5 seconds to 20 minutes. Values from 241 to 251 specify from 1 to 11 units of 30 minutes, yielding timeouts from 30 minutes to 5.5 hours. A value of 252 signifies a timeout of 21 minutes.5em 1em; color: #000; backgroundA value of 253 sets a vendor-color: #E6F2FF; margin: 3px 3px 1em 3px;">umount /var/hda/files/defined timeout period between 8 and 12 hours, and the value 254 is reserved. 255 is interpreted as 21 minutes plus 15 seconds. Note that some older drives/sdb1<br/>nano /etc/fstab</div> may have very different interpretations of these values.

In nano, It may make the system run cooler and power efficient (especially on a Home Server you'll need to add a new line are rarely using all of the pool drives at the bottom. Take the line that hda-diskmount gave you (the blue onesame time), and change the first value only.<br/>Instead of /dev/sdb1, enter '''UUID=''' followed by the UUID you found earlier.
