General :: DD Install From One Drive To Another (2 Different Sizes)
Oct 19, 2010
I just ordered a 60 G SSD drive which I am going to use as my OS drive to replace the drive below. Can I just use DD to switch ?

Usually I prefer to keep my operating system on a small partition (50 gigs or so), with the rest of my system on another partition. Normally, with windows (don't flame me for saying the W word!) a small OS partition makes sense.... this way i can scan for viruses, or defrag quickly-- two non issues with linux openSUSE. (with windows, i never install programs on my C: either; this keeps the OS partition small)One advantage at least on windows, with having a small operating system partition is that it's really easy to backup & restore. If my system gets wiped out, I only lose the OS and if i have to re-install, all my personal files are still there.
Is This Done for Me Already With the Default openSUSE Partition Set-up?I just got a new 1TB Seagate HD, which I'm going to use for development purposes in the openSUSE environment.I'm wondering if I can somehow apply my methodology explained above to openSUSE (or if it even makes sense). Are the default LVM partitions ideal for a clonezilla back-up? (can I just backup my primary partition, on the second partition somewhere in case I really mess up my machine). I've been using openSUSE for just a month now, and I'm really liking it (its my favorite linux OS now).

Opensuse Linux (Linux sr-server 2.6.37.6-0.7-default #1 SMP 2011-07-21 02:17:24 +0200 i686 athlon i386 GNU/Linux). I have a very unusual problem where fdisk reports one size BUT df reports a TOTALLY different and unexpected size. Besides doing a full backup, repartition, reformat and restore, is there anything else I can try first??
Here are the outputs: (sda1 and sda2 sizes are completely different from fdisk!!)
df -v -h
Filesystem Size Used Avail Use% Mounted on
rootfs 22G 17G 4.2G 81% /
devtmpfs 369M 152K 368M 1% /dev
tmpfs 375M 648K 374M 1% /dev/shm
/dev/sda2 22G 17G 4.2G 81% /
/dev/sda1 15G 7.8G 6.6G 54% /windows/C
FDISK reports correctly (sda1, sda2, sda3 = 24Gb, 949Gb, 3.1gb) .....

We talk about 12pt, 14pt font sizes. Do those numbers represent physical size in some unit or number of pixels? I guess it is the former, because same font size looks different for different DPI values, but in what unit? Also a relevant question: does browsers like firefox and chromium use different system of font sizes, because to get the same physical size, I alwasy need to set larger values in firefox than in other applications. Setting dpi and resolution values using about:config has no effect.

Let's say I want to get the size of each folder of a linux file system. When I use ls -la I don't really get the summarized size of the folders.If I use df I get the size of each mounted file system but that also doesn't help me. And with du I get the size of each subfolder and the summary of the whole file system.But I want to have only the summarized size of each folder within the ROOT folder of the file system. Is there any command to achiev that?

I have used cp -rl to copy a folder. When measuring the size of the source and of the result of the copy du -sl returns slightly different sizes, even though diff confirms that their content are identical.Both folders reside on the same hard drive, no modifications to any of them have been done between the copy and the measure. I found nothing in the documentation of du and cp which could explain the difference.

kernel 2.6.21.5, GNU (slackware 12.0)I have entered sourceforge.net. The fonts in their pages I find I cannot change their size. Neither ^+ (cntl++) has any effect. And the resolution I have it (/etc/X11/xorg.conf) at 640x480 (in this way I have a really big screen; so, big characters). I can't almost read that tiny characters.

I recently resized one of my Logical Volumes that contained 160MB data from 500MB to 6.5GB. After resizing it, I checked the size of the data via 'du -sh' and found that my data had reduced to 143MB.
Fortunately, I backed up the the 160MB of data on another partition before resizing the Logical Volume. I ran 'diff' on both directories holding the 160MB and 143MB, but there was no difference detected.
how come there is a 17MB difference after resizing?
In case you're wondering how I performed my resize, this is what i did:
e2fsck -f /dev/VolGroup01/LogVol00
lvextend -L +6G /dev/VolGroup01/LogVol00
resize2fs -p /dev/VolGroup01/LogVol00

The "[SOLVED]" attribute to the How to set defaulter size in RHEL5 thread notwithstanding, the problem really is not solved. I've set my default language to both "C" and to "EN-us" and the problem is that absolutely every single time I print, I have to meander through varying layout print menus to find the "A4" setting and change it to "letter". That, or sacrifice the last two lines on every page because the default size is larger than the actual size. Bad default. It is not unique to Red Hat/CentOS, of course. Same problem exists on Debian and SuSE, too. Why is this such an intractable issue? Why is there not some simple and obvious way to say, "squish all instances of A4 (or "letter") and replace with "letter" (or "A4")!"?

I am way new to Linux and am getting thrown into the deep end. My company is rolling out a Linux environment to support an application we are using. We are using RHEL for the OS. Does anyone have any recommendations for partition sizes?From what I can tell that appears to be the default values if you do a 'wife install' (yes, yes, yes, yes, yes) on RHEL.

I've been using Linux for about 15 yrs.. and this is driving me crazy.My daughter often plays on my linux box - a kinda-fresh f12 install.. running gnome.SO one day I go on my computer and my icons on my desktop are as if she changed my display to 800x600 - since the icons are so huge - but web browsing & once i open an application the sizing is fine.Wondering what she may have done to make my icons so huge.i can't seem to figure out any settings for this - she was messing with accessibility options since she had some software keyboard coming up at login too

I would like to create the following setup:
3 monitors: 1 2 3
monitor 1 and 3: 4:3 monitors, running 1600x1200, rotated 90 degrees
monitor 2: 16:9 monitor, running 1920x1080
Can this be done in Linux? If so: how? If not: what's preventing it from being possible?

In the past, I have used dd to replace (as well as overwrite) hard drives.
If you do a direct clone of a drive, you are supposed to make sure the target drive is the same size as the source drive.
It is quite important that I am able to clone a failing drive (250GB), however, my only other drive available is a completely new 1TB external hard drive from a different manufacturer.
Is it still possible for me to safely clone the failing drive? If yes, how would I go about doing this? Make a 250GB partition on the 1TB drive?
If I use the TB drive as a "temporary backup", and once I have copied over with dd burn everything directly to DVDs, and then restore the TB drive to it's original state, will this be able to be done?

I'm downloading the iso images for 9.10 Alternate CD. As the desktop does not work, graphical. For whatever reason even once it starts to boot live (With no direct install) it says in the "boot terminal" (non-graphical, full screen) as I call it "Authentication Failure even bEFORE the actual program is loaded. Asks me for username / password which does not exist, etc. I'm sick of windows. I used Ubuntu for about a week and fell in love.
Windows is poppy-cosh, compared to the speed, performance, customization, updates, few errors and bugs, everything is superb! I already converted my fiance and best friend to using the OS in Dual-Boot I'll be an avid supporter and do even more using my media company to help promote xD What's the point? Wine allows me to use all the programs I need that require windows, regardless.. You have converted me. "If you build it, they will come." Amazing job.
I tried re-installing windows and to no-evail for whatever reason screwed up my entire re-installation of Ubuntu. Instead of saying Owner it says Administrator for the new install. Here's my list:
1.) I need to completely wipe out all partitions and start over with a "fresh" HDD. Any ideas how to do so without an OS? It was suggested on wiki answers to use BootDisk.com
2.) I have the torrent downloading which is 689.6MB [URL] and the normal ISO which is 690MB [URL] from two different Ubuntu.com pages...Which do I use? Why are they two different file sizes? I assume the larger file size is the best to use. This has happened when downloading the Desktop CD as well. The lesser file never worked properly. Do you guys have incomplete files on the server or something or perhaps just my hardware?
3.) Use alternate installer to have Ubuntu as the ONLY OS. Alternate Option: Put Ubuntu alternate cd installer onto my external HDD by Seagate and boot up to it, then install ubuntu...

As a recent migrant to Ubuntu from Windows, I was expecting to be able to compare the sizes of two folders or set of folders by Bytes (as in windows). I'm slightly OCD when it comes to my personal files and folders, and I like to maintain identical backups in various pen-drives; as such, I was hoping to be able to track the file sizes of each folder set, but I can only do so in Kilobytes... Is there any application or other means by which to compare sizes in bytes --as is the case in windows?..

I need a command to list the total sizes for all the directories in a mounted drive.I tried df and du.df list the total size for the mounted drivedu depending on what option I give it either list the total size or list all the sizes for every file on the drive.All I want to know is the sizes of all the directories on the mounted drive.This is a windows vista hard-drive and for some reason ubuntu is reporting a 50 GB partition and only 10GB free, I want to know what's taking up all the free space. I can't find anything in the file browser, so far I've only managed to count up about 10GB of used space so where is the other 30GB.

System: Linux flashvoyager 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 07:54:58 UTC 2010 i686 GNU/Linux Ubuntu 10.04 Installed onto 64gig Flash Voyager GTR plugged into Tosh satpro laptop dual core 4 gig memory. This is not a casper r/w persistent install version. This is installed directly onto the flash pen and running as if the flash drive was a solid state disc.
I have obtained a 64gig which can read at 34mb/s and write at 28mb/s. The reason I wanted this was so I could install linux ubuntu and run the OS straight of the flash as if it was a Solid state disc. I have tried using the pendrivelinux method where the persistent data is stored inside a virtual file system but I found it did not allow grub or kernel updates without the need to rebuild the entire datapen plus I did not know how to get rid of the live boot menu where it asks for language and the like.
I boot the pen straight into linux ubuntu 10.04 via the bios boot menu and select the usb pen drive. Once into grub I select the most recent kernel and then load up ubuntu. When I first started using the distro from the pen the speed of the web browsing was so slow. I have since configured the browser to store the cache inside tmpfs /media/ramdisk and browsing seems fine now however there is underlying speed issue with using the method of install. Uncompressing installs takes an age. I have configured fstab like so:
#System
proc /proc proc nodev,noexec,nosuid 0 0
/dev/sdb1 / ext4 errors=remount-ro 0 1
[code]....
PS: I am not allowed to use the HDD on the laptop since it is company laptop. My previous company laptop had Kubuntu 8.04 with XP as VM. Also having the install on the flash drive would give me the convenience of booting the pen from any hardware.

I have Linux mint 8 iso and would like to install it on an Asus eee machine, for light web surfing and perhaps a movie only. I have istalled Linux mandrake once ages ago and red hat once too. The only other machine I have is a bigger netbook on vista, if I can get Linux working on the smaller then use it on my bigger machine too. Is it possible to use an USB HSDPA modem using mint on this netbook?

Having problems installing Xubuntu 9.04 to my Dell Latitude CPi (old, I know, but available...). Problem is that the CDROM is not working right and the BIOS doesn't support boot from USB so I can't do a complete live CD install via the CDROM or USB.What I'd like to do instead is install the ISO to the HD and run the install from that HD. Even with the CDROM problems I am able to load the Live CD installer from CDROM.
With that I think the best option will be to extract the ISO files to the HD (attach to another computer and extract to a FAT32 partition, then replace HD back in the latitude) then direct the liveCD bootloader to find the install files on the HD. Unfortunately I don't know the necessary commands to pass to the bootloader.

I'll select that drive and hit ok it just takes me back to the Universal Installer Screen. When I first started the Hard Drive was listed and somehow I must have removed it. Is there another program where I can select the HD and partition it etc.

I'm running the installer, and "Guided Partitioning" selected partition sizes I'm not completely happy with. I selected separate partitions for /home, /var, /usr, /tmp etc, and by default it gave me only 5GB for the /usr partition. I'd like to take some space away from /home and give it to the /usr partition, but I can't figure out how to do that using the menu options available.

In /etc/X11/xorg.conf, under Identifier "Screen0", add:
Option "UseEdidDpi" "FALSE"
Option "DPI" "90x90"

I have a few partitions on my hard-drive, one for Ubuntu, one for Windows 7 and another for general data storage. When I installed Ubuntu, I was presented with a GUI which allowed me to easily reassign storage space from the latter two to create the former. Is there any way to get to something similar, from which I can adjust the proportions of the partition sizes, without affecting their content?
