I need to setup a big hard disk (4TB) so that I'll be able to use it in both macOS and in a Raspberry Pi.  Up to now all my attempts failed - at the moment I have formatted it so that it uses GPT, type "linux filesystem", and all the 4TB are recognized - linux recognizes it but not the Mac  The solution proposed in  does not work since it suggests the MSDOS type, which doesn't work for big disks.  Is there a recommended way to solve this?

I have a USB drive that I can see/access/modify/etc in Linux/Ubuntu but it doesn't show up on my Mac OSX.  I did sudo fdisk /dev/sdb (where my USB is) and then g to create a new GPT partition table, n to make a new partition, used all default settings, then w to save and exit.  Then I did sudo mkfs.fat -F32 /dev/sdb1 to format the partition with a FAT32 filesystem.  I ejected the USB and put it in my Mac and it doesn't show up / get detected.  What did I miss?

I'm sure this has been answered somewhere on here before (I even found kinda a guide , but seemed to be a bit spotty and incomplete) but I was wondering if someone could assist me or at least point me in the right direction to get what I'm trying done accomplished.  Basically I installed Ubuntu 14.04 (via "Guided - use the entire disk and setup LVM") on a 20GB disk. I then physically added a clean 80GB disk to the machine, which it detects as 'sdb'.  Basically my question is, I want to be able to add/combine the allocated amount of space from the new disk (80GB) to my machine so that instead of showing two drives (20GB and 80GB), it simply shows one drive (100GB). I'm not worried about RAID or any other special add-ons.  I'm somewhat new to Linux, but understand that I need to use LVM to accomplish this.  If there is anyone who can help me out or link me to a helpful guide/tutorial, it would be very much appreciated! Not sure if this is needed either, but here is my 'fdisk -l' and '/etc/fstab' output:  fdisk output (shortened):  Disk /dev/sda: 21.5 GB, 21474836480 bytes    Device Boot      Start         End      Blocks   Id  System /dev/sda1    *       2048      499711      248832   83  Linux /dev/sda2          501758    41940991    20719617    5  Extended /dev/sda5          501760    41940991    20719616   8e  Linux LVM  Disk /dev/sdb: 85.9 GB, 85899345920 bytes Disk /dev/sdb doesn't contain a valid partition table  Disk /dev/mapper/ubuntu--vg-root: 20.4 GB, 20392706048 bytes Disk /dev/mapper/ubuntu--vg-root doesn't contain a valid partition table  Disk /dev/mapper/ubuntu--vg-swap_1: 801 MB, 801112064 bytes Disk /dev/mapper/ubuntu--vg-swap_1 doesn't contain a valid partition table   /etc/fstab (shortened):  # &lt;file system&gt; &lt;mount point&gt;   &lt;type&gt;  &lt;options&gt;       &lt;dump&gt;  &lt;pass&gt; /dev/mapper/ubuntu--vg-root /               ext4    errors=remount-ro 0       1 # /boot was on /dev/sda1 during installation UUID=26710773-7a64-4f34-a34e-0057cb1739d7 /boot           ext2    defaults        0       2 /dev/mapper/ubuntu--vg-swap_1 none            swap    sw              0       0

I would like to setup my Macbook Air's disk drive with 3 partitions - 50Gb for OSX Lion, 50Gb for Windows 7, and the remaining 150Gb for Data to share between both OSes (music, photos etc).  What's the correct way to do this?

I am a Linux user. I don't have Windows on my laptop. Also the hard drive size is less than 2 TB. Then why should I use GPT tables? Can't I go with old fasioned MBR?  I will be having two root partitions, two home partitions, and a swap space. So when a partition is not primary, but is extended, does that make any performance difference?

I have a USB device and i'm trying to create it in a way that it has 2 partitions: one for a live linux disc and the other for document storage.  I created the partitions using gparted and and set a boot flag to the one I want to use as the live disc. Now, I have a usb like this:  Disk /dev/sdc: 14.6 GiB, 15623782400 bytes, 30515200 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xc3072e18  Device     Boot   Start      End  Sectors  Size Id Type /dev/sdc1       8439808 30515199 22075392 10.5G 83 Linux /dev/sdc2  *      51200  8439807  8388608    4G  b W95 FAT32   I then used dd to flash an Ubuntu iso to /dev/sdc2  sudo dd if=/dev/shm/ubuntu-17.04-desktop-amd64.iso of=/dev/sdc2 bs=4M   When the disc is flashed onto the usb drive, I try to boot from my laptop and it shows "Operating system not found". When i try to use qemu/kvm, it shows a kernel panic like this:    How would I be able to do this properly?

I have a computer with two WD 1TB drives and I want to configure disk mirroring on it.  I tried setting up RAID during the installation by creating RAID partitions but that does not work for me.  Is there a convenient software that I can install to do the job for me? If no, what shell commands can be used?  Once it is set up how should I verify that it is working?

I've got Ubuntu 10.10 installed to use my whole hard-disk, but would like to use the 130GB of free space I've got to create a new partition and do some development on Unity and Natty.  Can I use gparted to do this?  If so how?

I know this  but there is no comparison to OSX's TimeMachine.  I would like to find a backup software which is about the same as TimeMachine or better.  I would like to have such a software which can use some format of HDD which is suitable for big files (50 GB) in Linux.  I noticed that   OSX format of HFS+ is not supported by Linux distros, since no maintainer of HFS in Linux since 2006 NTFS format made by Debian 8.1 is not supported by older Linux distros   If Windows support, good.   Try with the Backups (Deja Dup) software  I did start the backup first time but I wanted to go to lunch after backup was running already two hours of just 10 GB files.  So it gave me this after the lunch    which is really insane, reported now , since the software is not designed to have pauses in doing the backups.

I'm encountering a problem with my HDD's partitions and can't resize it. I've described my problem and my system here: .  Now, from a more general perspective, I was thinking on whether it is possible to use an Ubuntu Live CD and use GParted in a live session to possibly go around that problem. Is that possible? I made a separate question as I'm interested in the possibility independently from my current problem.  You see, I only have one partition and that's mounted. When I use GParted through Ubuntu I don't get any error reports (unlike the case reported in the question linked above).  Thanks beforehand.

The hard drive on my MacBook Pro has two partitions. One with the OS and the other with data.  Yesterday, from a USB boot drive, I performed a clean installation of Mountain Lion to the OS drive. I created the USB boot installer from InstallESD.dmg that I received from purchasing the OS from the Mac App Store.  Now I can't see or mount my data partition.  I'm wondering if there's a problem with the MBR. In Disk Utility it shows up as "disk0s4", but it's greyed out.  Any ideas on how I can mount the data partition so I can get my data off it?  For diskutil list disk0 the result is:   /dev/disk0    #:                                 TYPE NAME         SIZE       IDENTIFIER    0:                GUID_partition_scheme             *500.1 GB   disk0    1:                                  EFI              209.7 MB   disk0s1    2:                            Apple_HFS MacBook OS    99.5 GB   disk0s2    3:                           Apple_Boot Recovery HD  650.0 MB   disk0s3    4: 46860E2C-2310-4F96-99F6-616D0B4CB55D              399.6 GB   disk0s4   Here's the result of diskutil info /dev/disk0s4  Device Identifier:        disk0s4 Device Node:              /dev/disk0s4 Part of Whole:            disk0 Device / Media Name:      MacBook Data  Volume Name:              Not applicable (no file system)  Mounted:                  Not applicable (no file system)  File System:              None  Partition Type:           46860E2C-2310-4F96-99F6-616D0B4CB55D OS Can Be Installed:      No Media Type:               Generic Protocol:                 SATA SMART Status:             Verified  Total Size:               399.6 GB (399629668352 Bytes) (exactly 780526696 512-Byte-Blocks) Volume Free Space:        Not applicable (no file system) Device Block Size:        512 Bytes  Read-Only Media:          No Read-Only Volume:         Not applicable (no file system) Ejectable:                No  Whole:                    No Internal:                 Yes Solid State:              No

My hard drive died in my macbook and it no longer will start up. It will not mount in an external enclosure but disk utility is still reading that the hard drive is there, and I tried to repair disk and I am getting this error: (Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.) So my question is how do I backup my files if the hard drive won't mount? The only way that I have been able to see the hard drive is through disk utility. I just want to be clear that I am using mac os x snow leapard.

Let me tell the story from the beginning: I installed Big Sur on an unsupported Mac using guidelines at Medium. In the guide it was stated that I should create a separate partition for Big Sur, and shouldn't install it on my current one. I had my SSD Called &quot;Macintosh SSD&quot; and later I created a partition named &quot;Macintosh SSD Big Sur&quot; of size 40GBs. After installation I wanted to clear the &quot;Macintosh SSD&quot; of size 80GBs(with old MacOS) and merge it with the new &quot;Macintosh SSD Big Sur&quot;. This is what I initially had after formatting partition with the old MacOS  So, I used the command sudo diskutil apfs deleteContainer disk3 after which I had (free space) in /dev/disk1  I want to extend that 39.6GB partition which free space of 80,1GB but all the commands I googled do not work:(( Could you please guide me on what I should do now? Thank you in advance!

I'm very new to this and I've been at trying to fix this problem for about two hours to no avail.  I just finished getting my new computer put together and installed a new 2TB Seagate hard drive as a secondary drive (my boot drive has no problems at all). I have it formatted into two petitions, one in ext4 through GParted. I want to use this partition to store extra files and programs (specifically games and CAD stuff). I went to make a steam library folder in it and found that it's read only. It is at /dev/sda1  I first attempted to reformat it to no avail. I looked around for some help (most of what I found related to external storage) and tried a few things through the terminal to change the owner.  mount /dev/sda3 /mnt/   Returned "only root can do that."  I'm stuck past here, I've tried a couple other things I can't hunt down now, but every attempt gives an access problem to me. How can I change this and regain access? Are there more effective ways to map/install this drive for this purpose to avoid this problem in the future? Thank you!

Long story short, I have an external USB hard drive formatted using a MBR partition table, and I want to install Ubuntu in UEFI mode in a ~23.40 GB unallocated space before a ~442.33 GB NTFS partition that I need to keep:    To install Ubuntu in UEFI mode I need the partition table of the drive to be formatted as gpt.  I don't think there's an easy / direct way to convert a MBR partition table to a gpt partition table, so I'm also looking for the complicated / indirect way.  For example I think something can be done by noting down the NTFS partition start, writing the new partition table and adding the NTFS partition to the new partition table, but I've never done this and I have no idea where to start; furthermore I don't wish to try this for the first time in this case, since I'm not really confident with this stuff and I can't afford losing the NTFS partition I need to keep.

I'm looking to treat myself to a totally portable TeX system and was wondering: is it possible to devise an installation scheme that would run on Windows, Linux and MacOS at the "same" time?  I think TeXLive is the best choice here, but I'd much rather avoid having to maintain three separate TeXLive installations. I'd like the three installations to share the package databases for instance.  I'll be using a 32Gb USB stick, in case it matters.  PS: I think I'm onto something here... will post back when I have a working prototype.  Edit: after reading  I managed to format a USB stick with UDF and have it read and written in Linux and Windows (need to perform some tests on Mac yet). This is the first step towards interoperability.  Edit 2: well, as it turns out, the previous note was useless (the partition table breaks under Windows), I've found  and it works like a charm. The only remaining step is writing a couple of scripts to set the environmental variables and we're done ;)
