  • How can I copy data from a windows disk to another partition?

    - by TardisGuy
    I have a new Solid State Drive, and it's very fast (but tiny, 128GB). But it seems to be much faster in Linux. Now, am I correct in assuming that if I Gparted copy paste the {_Boot MSreserved__][_________NTFS__________] in to (1st Empty space, same partition) and it will be bootable, right? Will this work? I also heard I should turn off 'journaling' for the SSD filesystem. Is that needed for this as well?

  • preseeded installation keeps asking for confirmation while creating RAID-Partitions on certain hardware-platform

    - by Marc Shennon
    I am aware of the partman-md/confirm_nooverwrite thing, that was the solution to most of this problems in the past. The thing is, that the preseed-file works for almost all hardware-platforms I tested, but only for one (Primergy MX130) it keeps asking for confirmation, before writing the partition-layout to the disks. All machines I tested are running with two SATA Disks, nothing special. I'm not really sure, what information could be needed in order to investigate the cause of this behaviour, but I would of course be willing to provide more information, if someone has an idea. Relevant part of the preseed file is the following: d-i partman-auto/disk string /dev/sda /dev/sdb d-i partman-auto/method string raid d-i partman-md/confirm boolean true d-i partman-partitioning/confirm_write_new_label boolean true d-i partman-md/device_remove_md boolean true d-i partman/choose_partition select finish d-i partman-md/confirm_nooverwrite boolean true # Write the changes to disks? d-i partman/confirm boolean true d-i mdadm/boot_degraded boolean true # RECIPE # Next you need to specify the physical partitions that will be used. d-i partman-auto/expert_recipe string \ multiraid :: \ 500 10000 1000000000 raid $lvmignore{ }\ $primary{ } \ method{ raid } \ . \ 512 1000 786 raid $lvmignore{ }\ $primary{ } \ method{ raid } \ . \ 8192 10240 10240 raid $lvmignore{ }\ method{ raid } \ . # Parameters are: # <raidtype> <devcount> <sparecount> <fstype> <mountpoint> <devices> <sparedevices> d-i partman-auto-raid/recipe string \ 1 2 0 ext4 / /dev/sda1#/dev/sdb1 . \ 1 2 0 ext2 /boot /dev/sda2#/dev/sdb2 . \ 1 2 0 swap - /dev/sda5#/dev/sdb5 .

  • Moving 11.10 complete system to a new bigger Harddisk

    - by pl1nk
    I would like to move my current installation of Ubuntu 11.10 to a bigger harddisk, since the old one is failing. I would like to avoid solutions like dd block copying (since there would be unused space at the end) with something cleaner, but I'm open to suggestions. Partitions info: Size Used Avail Use% Mounted on Partition type Encrypted 19G 9.9G 7.6G 57% / ext4 59G 50G 6.2G 90% /home ext4 Yes What is the best way to accomplish such a task, preferably with advantages/disadvantages.

  • if a usb pen drive has 64349 cylinders, is it damaged?

    - by Andrew S
    I have a 4Gb USB pen drive that I'm trying to format with FAT32. When I run fdisk, it gives me this message: The number of cylinders for this disk is set to 64349. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) I've tried deleting the partition table, creating new partitions, etc, but they never work. Sometimes I can write to the drive the first time I use it after formatting it, but then it becomes read-only in both Windows and Linux. I've tried this on multiple computers. Am I doing something wrong, or is the drive reporting an incorrect number of cylinders? Is the drive itself likely to be corrupted, and is there anyway to fix this under Windows Vista or Linux? Thanks

  • cannot boot Ubuntu after fresh install

    - by Jonathan
    I just installed Ubuntu on a Lenovo v570, and cannot boot into the system. All I get is a loop, where some (bios) info is displayed, and then the computer asks me where I would like to boot from. I tried reinstalling, reinstalling with a custom partition scheme, and boot -repair after the install. None of these work. I can see the files on my harddisk have been copied. I have installed many Ubuntus in the past, as well other distros where custom partitioning is required. I don't know where to find any useful information since I don't even get too the grub menu. One odd thing I noticed. The bios now had options to boot USB, OpenSuse,Fedora, or the HD. I am not dual booting. I also realized that the boot info is for a network boot, which means the computer is not recognizing what to boot. It is boot an HD problem, because I can install other OSs just fine. I am completely stumped. I would like to settle this, and end up with a tutorial, that explains to me what happened.

  • Shakespeare and storing Unicode characters

    - by John Paul Cook
    This post is about the political issues involved with using multiple languages in a global organization and how to troubleshoot the technical details. The CHAR and VARCHAR data types are NOT suitable for global data. Some people still cling to CHAR and VARCHAR justifying their use by truthfully saying that they only take up half the space of NCHAR and NVARCHAR data types. But you’ll never be able to store Chinese, Korean, Greek, Japanese, Arabic, or many other languages unless you use NCHAR and NVARCHAR...(read more)

  • Java @Contented annotation to help reduce false sharing

    - by Dave
    See this posting by Aleksey Shipilev for details -- @Contended is something we've wanted for a long time. The JVM provides automatic layout and placement of fields. Usually it'll (a) sort fields by descending size to improve footprint, and (b) pack reference fields so the garbage collector can process a contiguous run of reference fields when tracing. @Contended gives the program a way to provide more explicit guidance with respect to concurrency and false sharing. Using this facility we can sequester hot frequently written shared fields away from other mostly read-only or cold fields. The simple rule is that read-sharing is cheap, and write-sharing is very expensive. We can also pack fields together that tend to be written together by the same thread at about the same time. More generally, we're trying to influence relative field placement to minimize coherency misses. Fields that are accessed closely together in time should be placed proximally in space to promote cache locality. That is, temporal locality should condition spatial locality. Fields accessed together in time should be nearby in space. That having been said, we have to be careful to avoid false sharing and excessive invalidation from coherence traffic. As such, we try to cluster or otherwise sequester fields that tend to written at approximately the same time by the same thread onto the same cache line. Note that there's a tension at play: if we try too hard to minimize single-threaded capacity misses then we can end up with excessive coherency misses running in a parallel environment. Theres no single optimal layout for both single-thread and multithreaded environments. And the ideal layout problem itself is NP-hard. Ideally, a JVM would employ hardware monitoring facilities to detect sharing behavior and change the layout on the fly. That's a bit difficult as we don't yet have the right plumbing to provide efficient and expedient information to the JVM. Hint: we need to disintermediate the OS and hypervisor. Another challenge is that raw field offsets are used in the unsafe facility, so we'd need to address that issue, possibly with an extra level of indirection. Finally, I'd like to be able to pack final fields together as well, as those are known to be read-only.

  • Why can't I install Ubuntu 10.04 on a system that already has Ubuntu 8.04?

    - by Android Eve
    Ubuntu 10.04 is beautiful. I love it. I am dying to install it on my PC, alongside the existing Ubuntu 8.04 (from which I write this message right now). But... it won't let me! When I reach the partitioning stage (manual!) Ubuntu 10.04 sees my two HDDs as one RAID volume. It doesn't see all the partitions I already have in place in /dev/sda and /dev/sdb. Even Windows 7 doesn't behave like this... (yes, I actually managed to install Windows 7 64-bit in dual-boot configuration with Ubuntu 8.04 on this same system). Note: GParted on Ubuntu 10.04 (live CD) sees the partition intended for Ubuntu 10.04 (/dev/sda4) perfectly, but is unable to format it. Any idea how to solve this problem?

  • Types in Lisp and Scheme

    - by user2054900
    I see now that Racket has types. At first glance it seems to be almost identical to Haskell typing. But is Lisp's CLOS covering some of the space Haskell types cover? Creating a very strict Haskell type and an object in any OO language seems vaguely similar. It's just that I've drunk some of the Haskell kool-aid and I'm totally paranoid that if I go down the Lisp road, I'll be screwed due to dynamic typing.

  • Way(s) of browsing the filesystem that are more flexible

    - by ixtmixilix
    I have two related questions, both probably (but not necessarily preferentially) accepting the same answer : When browsing or exploring the filesystem in a GUI, I want to be able to right click on the empty space between the files, choose a menu item and say 'open terminal in this folder,' optionally as root Do the converse when using the terminal, optionally as root I use Universe with kubuntu but have Debian Lenny running with gnome installed separately, so anything on kde or gnome would work

  • Development environment clean installation

    - by ruigoncalves
    Hi there! I'm about to install a new and clean development environment. To accomplish that, I would like a Windows operating system (possibly Windows 7) and a Ubuntu one (possibly the most recent, 10.04). To allow sharing data between the two operating systems, I'm thinking to create a partition (workspace, for example) with using NTFS to format it and that be automatically mounted by Ubuntu. In terms of the partitioning schema, how would be better to organize the previous mentioned partitions? Thanks in advance, Best regards!

  • How do I remap the keyboard shortcut for Gnome Do?

    - by johnc
    I am giving Unity a chance to win me over in Natty, but I admit I am a heavy Gnome Do user and Unity has remapped the Super+Space keyboard shortcut to show the Unity Launcher. I am not yet convinced with the new Unity Launcher and would like to keep using Gnome Do, at least until such time as I am convinced that the Unity launcher is as frictionless as Gnome Do. Is it possible to remap it to Gnome Do?

  • Phone number mask in a DataView WebPart (DVWP)

    - by PeterBrunone
    This came up today on the [sharepointdiscussions] list.  A user needed to display a read-only field in a phone number format; it's pretty simple, but it may be just what you need.Assuming your list item contains a field called "Phone Number" (with a space), the following XPath will give you a number in the classic US telephone format: <xsl:value-of select="concat('(',substring(@Phone_x0020_Number,1,3),')',substring(@Phone_x0020_Number,4,3),'-',substring(@Phone_x0020_Number,7,4))" /> If you need to mask an input, try this jQuery solution.

  • RAID 1 after install and two controlers

    - by jfreak53
    I have question regarding RAID 1. Can I setup software RAID 1 after having installed the first drive and setup ubuntu 12? I know that during server install and partitioning I can select RAID and setup then, but what I am not clear on is how in the world to setup RAID 1 after the fact? Can someone provide directions for this? Also, can I RAID 1 two drives one being 500GB and the mirror drive being 1TB? Of course the mirror drive would have a 500GB partition but that's my point. Lastly, can one drive be on IDE and the other on a SATA controller? I know speed will be an issue, that doesn't matter, I just need to know if it will work without corrupting data and if it's the same process? Thanks.

  • Compaq Presario V2000 Vista/7 trial virtualization

    - by James Schweninger
    I am currently studying for an A-Plus certification to which was recently added troubleshooting Windows 7 to the exam. You also have to be very familiar with Vista as well. I only have XP on my Compaq Presario V2000, but I wanted to set it up ( I believe I have the minimum requirements for both ) so that I could run trial versions of Vista and 7 virtually.Windows 2000 is also on the exam. Is there an easy legal way to do this? I wouldn't mind partitioning my HDD for the four operating systems either. Thnx if you have any ideas, JLS
