=Partition and Format Hard DrivePreparation=[[Open_Terminal_as_root|In terminal as root]], execute the following to capture current hard drive configuration:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> ls -l /dev/disk/by-id/ > before.txt cat before.txt</div>

This step is optional, and should only be executed if you want to delete the content of your new hard drive, or if the hard drive has not yet been formatted:EXAMPLE: lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-Hitachi_HDS722020ALA330_JK1131YAGDU37V -> ../../sda lrwxrwxrwx 1 root root 10 2010-02-18 03:24 ata-Hitachi_HDS722020ALA330_JK1131YAGDU37V-part1 -> ../../sda1

You should (unless you have a good reason not to) use GParted to partition Power ''OFF'' the HDA and format your install/connect any additional hard drive(s).<br/>Not having X installed would qualify as a good reason! In such cases, either use SSH X11 Forwarding (Google that if you'd like to use this), or [[Adding_a_second_hard_drive_to_your_HDA#Using_cfdisk|use cfdisk]] from a [[Open Terminal as root|Terminal, as root]].

You'll probably want to create a single partition, and format it as =Identify=Power ''ext3ON''.<br/>Note that Windows can't read ext3 partitions, so if you want dual-boot Windows on your Amahi PC, or if you intend to connect this hard drive to a Windows computer later, you should format as NTFS instead, the HDA and you should do that on Windows before you connect collect data about the new hard drive in your HDAconfiguration.<br/>Remember that using NTFS partitions on Linux will be slower that using ext3 partitions Again, so you should only use NTFS if you really need it.<br/>How much slower: compare the blue bars (NTFS-3G) with the red bars (ext3) on [http://www.tuxera.com/products/tuxera-ntfs-commercial/performance/ save this graph]to a text file for reference.

To know what device (/dev/sdX) you need to partition and format, use the following command, in a [[Open Terminal as rootOpen_Terminal_as_root|Terminal, In a terminal as root]], execute the following to capture current hard drive configuration: <div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> ls -l /dev/disk/by-id/> after.txt cat after.txt

Find the row corresponding to your hard drive, and look at the end of the line to identify the correct device to use. Example:<div style="borderEXAMPLE: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"><small> [gb@hda ~]$ ls -l /dev/disk/by-id/ total 0

In the above example, :'''FYI:''' IDE/dev/sdb would be what I would select in GParted (or use on the cfdisk command). sda in my primary SATA hard drive, drives will start with '''ata-''' and sdb my second USB hard drivedrives will start with '''usb-'''.<br/>

Select [[Open Terminal as root|In a Terminal, as root]], execute the device (following:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> diff before.txt after.txt</dev/sdX) that you found above.div>

In the above example, :EXAMPLE: lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-ST31000528AS_6VP08W65 -> ../dev../sdb would be what I would select in GParted.

You should Google for onebe preserved, skip to find one that seems clear to youthe [[Adding_a_second_hard_drive_to_your_HDA#Mount|Mount]] step.

Here==Command-line (Fedora)==To partition the hard drive(s), substitute sdX with hard drive device name, such as ''sdb''s a general introduction on [http://www.youtube.com/watch?v=vdWkdrnNGRg YouTube]. Just use ext3 or ext4 instead of fat32 in you follow that tutorial.

2. Then edit /etc/fstab to mount Take note of the UUID's for each drive - for novices, easiest to do this using a graphical editor.

sudo nano /etc/fstab

3. Then '''very carefully''' add the following line for each disk into the end of the fstab file. Make sure you paste in the right UUID, drive number and drive file system (ext4 in this case).  <div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; marginEXAMPLE: 3px 3px 1em 3px;"> UUID=55d9333f-d801-425a-b2af-d65c5966d56f /var/hda/files/drives/drive1 ext4 defaults 1 2</div>

It should look something like the following when lines are added for each of the five drives in this example. Note lines beginning with # are comments where the remainder of the line is ignored)

<div style="border: 1px solid #A3B1BF; paddingEXAMPLE: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;">

Save the file and quit the editor. To see if that will work at boot time[[Open Terminal as root|In a Terminal, as root]], try execute following command (replace '''sdb1''' withthe (<strong style="color:blue">BLUE</strong>) value you received from ''hda-diskmount''):

mount e2fsck -acn /dev/'''sdb1'''

If that gives you errors, there is a good chance that Most drives will power down on their own without doing this line was not added properly and your machine may not reboot and get stuck mounting the drives!.

Note that 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 hda-diskmount command had already added lines S timeout value is somewhat peculiar. A value of zero means "timeouts are disabled": 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 mount my OS drive which had two partitions (root or /5.5 hours. A value of 252 signifies a timeout of 21 minutes. A value of 253 sets a vendor-defined timeout period between 8 and 12 hours, and home)the value 254 is reserved. Save file and close255 is interpreted as 21 minutes plus 15 seconds. Note that some older drives may have very different interpretations of these values.

4It may make the system run cooler and power efficient (especially on a Home Server you are rarely using all of the pool drives at the same time) Save file and reboot machine.

5) Check that drives have successfully mounted in Amahi =Troubleshooting===hda (Setup - Shares diskmount==If ''hda- Storage Pool)diskmount'' does not mount the hard drive or you prefer to do it manually, complete the following steps:
