3Tb drive (raw) showing as 746.51 Gb...
location: ubuntuforums.com - date: September 7, 2011
Title says it all; it's a new drive, and all that shows is 746 Gb HDD space.
Any ideas about how to proceed here? Like maybe go ahead and format, with disk label assignment, and see if the rest of HDD space shows up?
3TB drive appears as 2TB with LVM
location: ubuntuforums.com - date: April 29, 2012
I just bought a 3TB drive for the purpose of adding to the LVM pool in my server. After formatting it as Linux LVM, the LVM utilities are detecting it as 2TB only. fdisk -l shows 3TB. I've added all the space to a logical volume, because I thought another terabyte available to my other volumes.
What can I do?
3TB external drive inaccessible (recognized as only 2TB)
location: linuxquestions.com - date: September 8, 2014
I have a 3TB 3.5" WD SATA drive connected via eSATA.
I created it as a GPT with protective MBR and 1 single 3TB ext2/3 partition.
My PC has a BIOS and I use Grub2 as boot loader. See attached BIOS.txt
All worked great for some time, then it suddenly isn't recognized anymore (possibly after a reboot, not sure).
I am running Fedora 19 kernel 3.14.17-100.fc19.x86_64
lspci listing attached as lspci.txt
gdisk info attached as gdiskinfo.txt
Basically it seems:
my backup GPT header is corrupt (CRC errors)
my main GPT header is not corrupt
MBR is showing a 2.0TB device with single 2.0TB partition (as expected)
GPT is showing a 2.0TB device with single 2.7TB partition
one strange sidenote (maybe unrelated):
the partition type seems to be 0700(MS basic data). Shouldn't this be 8300 (Linux filesystem) since I created this drive in Linux?
Because the partition size in GPT is larger than the apparent disk size, gdisk won't allow me to make any changes.
[Solved] Hard Drive not showing up on install of ubuntu 8.04/8.10
location: ubuntuforums.com - date: January 15, 2009
Trying to install ubuntu 8.04 or 8.10 on my desktop. When in the partitioning step of install there is no hard drive showing up to partition.
I have tried doing the wubi install but get a initramfs prompt showing up when booting into ubuntu and nothing after that. I have vista installed on the hard drive and reformatting the drive is not an option.
The hard drive i'm trying to install on is a western digital 500GB SATA drive.
I have tried setting drive to AHCI mode as read from other posts that might help.
Please help, new to linux.

Mounted Drive Not Showing Up in Unity Launcher
location: ubuntuforums.com - date: September 10, 2013
I am currently using Ubuntu 13.04 and I tried to update the kernel today to 3.11. After doing so I was having issues with Unity where I could log into my user account but it would only display the wallpaper. I couldn't see the Unity launcher or menu bar.
So I rebooted my system and through GRUB I booted using the previous kernel. Same thing happened and I only had wallpaper. Was able to get everything back again by performing the below tasks.
dconf reset -f /org/compiz/
unity --reset-icons &disown
So now I am back to the 126.96.36.199 kernel, I have purged the 3.11 kernel and my Unity Launcher and menu bars are back and things are functioning as normal.
The issue I am having now though is when I go to files and mount my Windows Drive (to access the files located in the drive) it doesn't show up as being mounted on the Unity Launcher. It does show as mounted in Files and I can navigate and open all my files as normal, but nothing shows up on the launcher indicating it is mounted. Usua
Formatting a 3TB drive GUID partition table
location: ubuntuforums.com - date: August 23, 2012
How do I get the server to see a 3TB drive? I was told to drop the old partition table and put a guid partition table on instead. That I did but the drive still only reads out at 802GB. What am I missing in the recipe? I want to end up with NTFS on it because that is all the person I am sending it to can read, but it cannot be a mbr partition table or whatever MS puts on their extra-large drives because I cannot read it on my Ubuntu servers or Debian servers.
I am writing this from a Debian server with a 3.2.0 kernel. My Ubuntu Server is a Ubuntu10.04 server with 2.6.32-41 kernel. The Ubuntu server could be too old, I guess, but the Debian one is running Wheezy with backports on.
3Tb drive 4096 sector partition alignment
location: ubuntuforums.com - date: September 29, 2012
I'm in the process of setting up Ubuntu 12.04 LTS Server for my home server, and am installing a Seagate Barracuda 3Tb drive as the data drive called /dev/sdb (Ubuntu is happily installed on an SSD - /dev/sda).
I've realised that I have to use parted because fdisk doesn't like drives larger than 2Tb.
I've run parted -a optimal /dev/sdb, then created a primary partition over all of the drive. Seems to work okay.
Within parted, the align check always comes back as aligned.
I then use mkfs.ext4 to create an ext4 filesystem on that single partition. Again, it seems to work fine.
However, if I do a sudo fdisk -l, it tells me under /dev/sdb that Partition 1 does not start on the physical sector boundary.
Which program is telling the truth?
Hope someone can help. This drive will be storing all of our movies, photos etc, so I don't want to take any chance with the partition being out of alignment and it becoming unstable or slow.
Regards, and thanks in advanc
Swap partition showing as unknown
- date: August 31, 2011
I just reinstalled Ubuntu 11.04 on my netbook, and I've noticed that my swap partition is now showing as "unknown" in GParted (I recreated the partitions completely when I reinstalled, so it's not an old swap partition), I don't remember it showing as unknown before reinstalling, but I'm not completely sure.
When I execute 'free' on the terminal, it shows the swap space as available (output pasted below if it matters), and swapon -a and swapoff -a execute fine with no errors, so I assume that there's no actual problem with the swap, but rather the problem is with GParted, so it's not a big issue, but I'd like to understand why this is happening and possibly fix it.
