I know my disk is 120GB so that's the right one. This tells us the name of the new disk which is "sdb" in my case. Running :EXAMPLE: $ sudo /sbin/fdisk lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-ST31000528AS_6VP08W65 -lu > ../dev../sdb | grep NTFS

In my case, there' For hard drive(s just one partition, sdb1) that contain data to be preserved, so this is skip to the partition I will mount[[Adding_a_second_hard_drive_to_your_HDA#Mount|Mount]] step.
Now we can go on to create ==Command-line (Fedora)==To partition the mount points if needs be. But because my disk contains all my musichard drive(s), I want it to be mounted as if it were my local "Music" foldersubstitute sdX with hard drive device name, so for me the mount point already exists. But if just want to access your disk easily you could just such as easily mount it anywhere. Commonly mount points are put in either /mnt/ or /media/. It doesn't matter where - just be consistent when you are doing this. To do this run these commands as root'sdb'': $ cd /mnt/ $ mkdir my_ntfs_disk
Substituting my_ntfs_disk for whatever you want [[Open Terminal as root|In a Terminal, as root]], execute the following:<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> parted /dev/sdX</div></blockquote>Up to call it2TB, at the ''(parted)'' prompt, enter:# mklabel msdos (answer ''yes'' if prompted)# mkpart primary 0% 100%# quit<br />Greater than 2TB, at the ''(parted)'' prompt, enter:# mklabel gpt (answer ''yes'' if prompted)# mkpart primary 0% 100%# quit<br />Verify the new partition was created:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> ls -l /dev/disk/by-id/</div>: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 lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-ST31000528AS_6VP08W65 -> ../../sdb <span style="color:#FF0000">'''lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-ST31000528AS_6VP08W65-part1 -> ../.. /sdb1'''</span>
Now we can mount the disk The new partition is named sdX1 (i.e. sdb1 in the desired location. Again as root run this command<span style="color: $ mount #FF0000">'''RED'''</dev/sdb1 /mnt/my_ntfs_drive -t ntfs-3g -r -o umask=0222span>).
This command will make Format the mounted drive read only.

==GParted (Ubuntu)==From the HDA desktop (or in my caseusing VNC), [[Open_Terminal_as_root|In a terminal as root]] and type '''gparted''' to launch the application.
$ mount Here's a general introduction on [http:/dev/sdb1 www.youtube.com/home/USERNAME/Music -t ntfs-3g -rw -o umaskwatch?v=0000vdWkdrnNGRg YouTube]. Just use ''ext3'' or ''ext4'' instead of ''fat32'' if you follow that tutorial.
because I want it mounted For drives > 2.0 TB, following these steps:* Choose hard disk in my "Music" filethe dropdown menu (top right)* Select Device > Create Partition Table...> Advanced > (Choose 'gpt')* Create partition
Remember in both of these commands you'll need to substitute sdb1 with whatever the partition name/number is on your machine. And in the second command USERNAME is your linux username.
If you now go to your desktop:<b>NOTE:</b> [http://gparted.org GParted] supports GUID-partitioned drives, however, you should see the drive is mounted there.

Edit ''/etc/fstab'' to mount each drive:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> nano /etc/fstab</div>Then '''very carefully''' add the following line for each disk into the end of the fstab file. Ensure correct UUID, hard drive number and hard drive file system (ext4 in this case) are added. :EXAMPLE: UUID=55d9333f-d801-425a-b2af-d65c5966d56f /var/hda/files/drives/drive1 ext4 defaults 1 2 It should look something like the following when lines are added for each of the five drives in this example. :EXAMPLE: # Mounting Greyhole Drives for Drive Pool. # # Drive1 = Seagate-Alpha2TB in Microserver Bay 1 from left UUID=55d9333f-d801-425a-b2af-d65c5966d56f /var/hda/files/drives/drive1 ext4 defaults 1 2 # # Drive2 = Seagate-Beta2TB in Microserver Bay 2 from left UUID=5bd5498f-30c1-4780-948e-ca46656507d2 /var/hda/files/drives/drive2 ext4 defaults 1 2 # # Drive3 = WD-Charlie2TB in Microserver Bay 3 from left UUID=a7337504-376a-4d36-9f7a-1a24c0f55fbd /var/hda/files/drives/drive3 ext4 defaults 1 2 # # Drive4 = WD-Delta2TB in Microserver Bay 4 from left UUID=8d881dcb-8de3-4621-b9bd-00025196868a /var/hda/files/drives/drive4 ext4 defaults 1 2 # # Drive5 = 250GB OS Drive mounted in Optical Drive bay UUID="4d6f8004-d190-4234-a03b-b68de988abf0 /var/hda/files/drives/drive5 ext4 defaults 1 2 # # :'''NOTE:''' Lines beginning with # are comments where the remainder of the line is ignored Verify there are no issues by executing the following:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> mount -a</div>If there are errors,most likely a line was not added properly. If this is not corrected, the machine may not boot and hang trying to mount the hard drives! Once there are no errors, reboot machine:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> reboot</div>Verify the hard drives have successfully mounted in the '''HDA Dashboard'''. If all drives mounted successfully, it should look something like this (Ubuntu): :EXAMPLE:[[File:Gstreet_greyhole_pool.png|options|caption]] ==Bad Blocks==Optionally, you can test your new drive for bad blocks.<br/> :'''NOTE:''' This can take a ''long'' time to complete! Recommend starting it in the evening so it will be completed the next day. [[Open Terminal as root|In a Terminal, as root]], execute following command (replace '''sdb1''' with the (<strong style="color:blue">BLUE</strong>) value you received from ''hda-diskmount''):<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> e2fsck -cn /dev/'''sdb1'''</div>You'll receive a message stating '''WARNING!!!''' ''Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage. Do you really want to continue (y/n)?''<br/> Answer ''yes''. The <code>-cn</code> option we're using can safely be used on mounted file systems.==Spin Down Hard Drives== Low power is a good thing to have in servers. If you do not use your server very often, you may want to force the hard drives to spin down faster than the default. Here is how. First ensure ''hdparm'' package is installed: sudo dnf install hdparm To force to spin down after 10 minutes of being idle, add these lines to <code>/etc/rc.local</code>:<pre># power drives down after 10 minutes idle/sbin/hdparm -S120 /dev/sda/sbin/hdparm -S120 /dev/sdb...</pre> 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": 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. A value of 253 sets a vendor-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 may have very different interpretations of these values. It 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). =Troubleshooting===hda-diskmount==If ''hda-diskmount'' does not mount the hard drive or you prefer to do it manually, complete the following steps: Create the mount point (choose one '''NOT''' in use) [[Open Terminal as root|in a Terminal, as root]] by executing the following:<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> mkdir -p /var/hda/files/drives/drive1</div></blockquote>Identify the hard drive to mount and copy the UUID from the output that corresponds to the hard drive (i.e. sdb)<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> ls -l /dev/disk/by-uuid/</div></blockquote> :EXAMPLE: lrwxrwxrwx 1 root root 10 Dec 29 18:10 1b8597e0-5d95-4474-b093-53099c8c81c9 -> ../../sda1 lrwxrwxrwx 1 root root 10 Dec 29 18:10 1c161033-c695-4291-aba1-257d3987edf7 -> ../../dm-0 lrwxrwxrwx 1 root root 10 Dec 29 18:10 b7017251-cb54-438b-92a3-781537c565e6 -> ../../sdb lrwxrwxrwx 1 root root 10 Dec 29 18:10 c1fe62b3-41dc-4a67-8a6b-09f90b7893ba -> ../../dm-1 lrwxrwxrwx 1 root root 10 Dec 29 18:10 e0f5a9bd-f52b-431e-89af-61da70659bdd -> ../../dm-2 lrwxrwxrwx 1 root root 10 Dec 29 18:10 <span style="color:#FF0000">'''547b073d-e591-4913-b4fb-7c5084353979'''</span> -> ../../sdb1 :The UUID for sdX1 (i.e. sdb1 is <span style="color:#FF0000">'''RED'''</span>).Add the following to the end of ''/etc/fstab'', replacing the UUID as captured in the previous step<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> nano /etc/fstab</div></blockquote>:EXAMPLE: # # /etc/fstab # Created by anaconda on Sat Nov 9 01:46:39 2013 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # UUID=1ebbf241-528c-465e-889f-acc15400dd8c / ext4 defaults 1 1 UUID=087b15a5-c3ca-4615-b6ee-bf5f399a803e /boot ext4 defaults 1 2 UUID=75346b8e-b162-458c-b0e9-a8d48ec2bc82 swap swap defaults 0 0 UUID=ad85eeb9-18f0-4b85-9bfa-b88a5d1489b3 swap swap defaults 0 0 <span style="color:#0000FF">'''UUID=547b073d-e591-4913-b4fb-7c5084353979 /var/hda/files/drives/drive1 ext4 defaults 1 2'''</span> :The new entry will be mounted as ''/var/hda/files/drives/drive1'' (i.e. sdb1 in '''<span style="color:#0000FF">BLUE</span>''') Mount the hard drive<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> mount -a</div></blockquote>:If all goes well, there should not be any output.
