One nice Gnome application is baobab. It comes with default ubuntu installation. To get it, sudo apt-get install baobab apt-cache show baobab Description-en: GNOME disk usage analyzer Disk Usage Analyzer is a graphical, menu-driven application to analyse disk usage in a GNOME environment. It can easily scan either the whole filesystem tree, or a ...

In my experience, I don't think there is something faster in the command line as dd. Adjusting the bs parameter can increase the speed, for example, I have 2 HDD that I know have a read/write speed greater than 100 MB/s so I do this: dd if=/dev/sda of=/dev/sdb bs=100M There is also pv (Needs to be installed first) that checks for the fastest speed on both ...

ncdu If you use the command line, you could use ncdu. It uses a command-line GUI (ncurses). Installation sudo apt-get install ncdu Description From its webpage: [...] ncdu: A disk usage analyzer with an ncurses interface, aimed to be run on a remote server where you don't have an entire gaphical setup, but have to do with a simple SSH ...

Keep the /home partition Yes! You can keep the existing home partition using one of the advanced installation options called Something Else After choosing this option, you will be able to tell the installation process to use the existing / and /home partitions. Make sure to choose to format / partition as ext4 and Not format (remove the check mark) ...

First, note there is a typo in mount your command. It should be: $ sudo mount /dev/sda2 /media/username Here /dev/sda2 is the device (in this case, a hard drive's partition) you want to access, and /media/username is your mountpoint, i.e., the location in the filesystem where you want to mount the device. To answer your questions: Yes, using cd is the ...

The problem is your connection type, and block size. For the fastest results your block size should be half the lowest write speed you typically receive. This will give you a safe margin, but still allow for a large number; of course you need to have enough ram to hold the data too. Usb 2.0 is 12 megabits per second (Mbps), Usb 2.0 High Speed is 480 Mbps. ...

Known Bug There is a bug (see below) that overwrites the UUID for the partition as soon as data is written to it. Therefore, you cannot use the UUID to reference the partition to use for encrypted swap. These days, swap space is hardly ever used. On my machine, swap is only used when I open my 40th tab. When I have no swap, suddenly my computer starts ...

Firstly, the "partition merging" question you ask. There is no "merging" of partitions - the actual 'merging' involves deleting a partition completely and then manually expanding the partition (in layman's terms). Because there is no 'merging' of partitions, your question on it is going to be answered with a "No, there will be no merging of partitions". I ...

In general, they should leave each other alone. If you do the install correctly (Windows first, then Linux, as a rule, because Linux is more 'considerate'). As far as I am aware, there is no additional risk involved in sharing a drive. Having said that, here are some gotchas to watch out for. 1) Windows will not be able to see the contents of your Linux ...

It is safer to use 2 hard disks. during formatting it is easier to recognize the different hard disks. 1 will be named sda and the other sdb. Though the installer puts names next to bootable partitions it does help to find other partitions that belong to that specific OS (like a D: drive will be sda2 on sda where sda1 is the OS for Windows or db2 is a ...

First some background:The rule of thumb in use for the last 25 years has been a minimum of 1xRAM and maximum 2xRAM. That minimum today is chosen so hibernation is possible and the maximum because of diminishing returns: it's just too slow to have to swap so much memory as HDD access is a factor of 1000 slower then RAM: good in an emergency, but not really ...

In the Unity applications dash look for "Disks". It's a disk manager that you can use to apply a partition table (choose mbr/ms-dos), create a partition, and add a filesystem to your second hard drive. Then you should be able to mount the partition, and see it.

If you have a OEM-preinstalled copy of Windows 8 or later Computers with OEM installs of Windows usually come with more than 1 or 2 partitions. Starting with Windows 8 the partition table should be GPT, allowing for more than 4 primary partitions. 1. Resizing the Windows partition There are at least 2 ways doing this: from the live media in Windows A. ...

I know Windows well but Ubuntu not so well (or the other way around) Both Windows and Ubuntu are POSIX compliant operating systems and they both allow you to define which user has access to which individual file, directory, partition or disk! But they do it just a little bit differently (There are full-time jobs for people who have to clean up wrong ...

Another very useful app for this is: JDiskReport Is very similar to windows SpaceSniffer and has a very useful and intuitive IU. You need Java to use it but it can run in every OS with Java An image to see the user interface: Hope it helps !

In a hybrid SSHD all SSD access is integrated with the hard drive's firmware and should not be controlled by the OS. You will be safe to just use, partition and format your 500 GB hard drive and rely on the engineers of that drive to give you optimum performance from the integrated SSD cache. Also see Is Seagate's new "FAST Factor Boot" ...

I'm an expert at both Windows and Ubuntu Good! Welcome! :-) You've probably read the non-expert versions above and wondered what's in it for you... Well, I'm not going to tell you that: creating 4 primary partitions on one single MBR drive is locking yourself in a corner (though some of the users above will have them on a GPT drive), nor what ...

From the fdisk and lsblk output we can see that: /dev/sda1 is your main partition, and is used for the root mount point (/), which holds everything else. How to understand the Ubuntu file system layout? /dev/sda2 is an extended partition - which means you are using an MBR partition table instead of GPT. The Ubuntu installer usually sets up one extended ...

I'm a beginning user of Windows and/or Ubuntu Both Windows and Ubuntu are advanced operating systems that allow you to define which user has access to which individual file, directory, partition or disk! But defining all these access rights can be a cumbersome task. (There are full-time jobs of people just doing this all day long!) So take the average ...

It seems like you need a bit more information on the Linux directory system: You have one root directory / on your system. And this is where you have a number of folders like /home, /dev, /usr, /etc and so on. Some of the folders really exist on the disk, like home, usr and etc, but some are only virtual like proc or dev and contain temporary ...

As long as you always mount your separate data partition I can see little if no benefits for the security aspects you mentioned. Any mounted partition including your data partition can be written to by you and by all your applications in case you had the appropriate permissons. A virtualised Windows will however only be able to access you data in case you ...

Okay so I tried and got the same problem. You can get round it by using a IDE controller based HDD rather than a SATA ( which is default ) Edit your VM -> Settings -> Storage, then add a HDD to the IDE controller and delete the SATA controller. Reboot the it should work okay.

Do you have long-term experience with such a dual-boot setup and can recommend it? Yes and yes. I started using Dropbox just after it started and have been using the same disk space for Windows and Ubuntu. This setup will be my daily driver so it should be reliable. I had some bad experience with dual-boot so I wanted some confirmation that it will ...

swap / /home efi Why? Indeed, the beginning of a HDD is faster then the end (SSDs are entirely different animals), and when you need to swap, you want it to be as fast as possible. You want your applications, temp files, ... to start as fast as possible to have a nice user experience. (For completeness: If you're running a database server, put the ...

Because those values aren't UUIDs; they're NTFS serial numbers. They're identified as UUIDs in /etc/fstab (and elsewhere) because the developers chose to use the identifier "UUID" for fundamentally non-UUID data, rather than use some other identifier. The same is true of FAT, by the way, but FAT serial numbers are even shorter than NTFS serial numbers.

I was having the same exact problem in Ubuntu 14.04 and came across this thread; this link that mutant provided worked well for me. I used the /dev/disk/by-id reference rather than the /dev/sdXY, as that reference is not always pointing to the same physical partition. My /etc/crypttab ended up like: cryptswap1 /dev/disk/by-id/wwn-0x500...-part6 ...

You cannot get rid of a GPT partition. GPT is a table type as is an MBR partition table. Since it appears you have a Windows 8 installation disc you can always disable UEFI, and install both operating systems in CSM (legacy bios mode) with an MBR partition table. If you wish to install under UEFI then use GPT for both operating systems. If Ubuntu isn't ...

Just create a new partition table, and this will get rid of all the partitions. You can do this in Gparted by going to "Device" and then "Create Partition Table".

To copy a partition wholesale, use cat instead of dd. I ran benchmarks a while ago, copying a large file rather than a partition, between two disks (on the same disk, relative timings are different): dd bs=64M 51.3 dd bs=1M 41.8 dd bs=4k 48.5 dd bs=512 48.9 cat 41.7 cp 45.3 The conclusion from this benchmark is that the ...
