  • Hard drive corrupts when fiddling with partitions.

    - by Archagon
    I've had problems with my hard drive ever since I got it a year ago. For the most part, it works fine, but whenever I try to do anything with partitions, be it adding, deleting, or resizing, some of the data in my other partitions inevitably corrupts. I've tried formatting my entire drive, but to no avail. What's going on?

  • Partition falsly recognized as RAW

    - by Paul Hiemstra
    On my 2 TB data disk I have two primary partitions, one of 1.6 TB for data storage in Linux (ext3) and one of 300 GB for some additional data storage for Windows. I run a dual-boot Windows 7/Ubuntu 12.04 install. The issue I have that if I start my computer into Windows 7, bot the partitions on my 2TB data drive are not recognized. In stead, Windows 7 sees one 1TB partition with type RAW. However, if I reboot to Linux, and then back to Windows 7, the partitions are correctly recognized. The following two screenshots illustrate my situation. Before I reboot to linux: and after the reboot: I have two questions: What could cause this behavior? How can I solve this issue.

  • Ubuntu not showing hard drive

    - by ojek
    I have a laptop which had a broken installation of Windows 7 installed on it. I created a Ubuntu live USB and tried installing Ubuntu over that Windows 7. After a few minutes, I got an error message, so I needed to restart the computer. Now the laptop says that there is no bootable device - reasonable message given that there was an error during Linux installation. However: BIOS can see my hard drive, When I start Ubuntu in live mode, and try either sudo fdisk -l or gparted, it doesn't show any hard disk drives. I am 90% sure that the hard drive is broken, but it is weird that BIOS can see it, and Ubuntu doesn't. How can I be 100% sure about that hard drive? Is there any additional way of detecting my hard drive from Ubuntu?

  • Linux cannot see Windows 7 partitions on install

    - by Nash0
    I've been trying to install Linux as a dual boot with Windows 7 on my Dell latitude e6510. It is currently running Windows 7 and I have used the MS disk tools to shrink the Win 7 NTFS partition to make room for Linux. The issue I'm having is that when I run Linux installers by boot from CD they see the entire hard drive as unallocated space. I have tried Ubuntu 10.10, Kbuntu 10.10 and Fedora 14 and they all have the same problem. I have also tried the Ubuntu "install in Windows" option and could not get it to work. EDIT: Booting Gparted 0.8.0 from a usb drive did not work. It reported the entire drive as unpartitioned.

  • What are the current options to encrypted a partition on mac os x ?

    - by symbion
    I recently got my laptop stolen with some sensitive informations on it (personal source code, bank details in a secure file, passwords, etc) and I learnt the lesson: encrypt your sensitive data. Now, I am wondering what are the options to encrypt a partition (not an encrypt disk image) ? Aim: The aim is to prevent anyone (except me) to access those data. Requirement 0: The software must be able to encrypt non system partition. Requirement 1: Plausible deniability is required but preventing cold boot attack is however not an absolute requirement (I am not famous enough or have sensitive enough info to have this kind of requirement). Requirement 2 : Software taking advantage of AES hardware encryption are very welcome as I intent to get a Macbook Pro with i7 CPU (with AES-NI enabled instructions). I will have avirtual machine running in the encrypted partition. Requirement 3 : Free or reasonably cheap. Requirement 4 : Software must run on Mac OS X Snow Leopard or Lion. So far, TrueCrypt is the only option I have found. Regards,

  • Linux cannot alter partition table of main hard disk of my laptop

    - by djechelon
    I run openSUSE 12.2 on my ASUS N76VZ laptop. My problem is that I cannot alter the partition table of first hard disk /dev/sda1. YaST partitioner says it's unreadable, but actually it can read it but not alter it. It doesn't tell me anything else, except that I can wipe the partition table (having to reinstall Windows for the third time). Since I want to create new partitions on that disk, how do I fix the partition table layout? I could create new partition from Windows Computer Management and format them in Linux. I could do this, but it doesn't explain the problem

  • Can I delete the OEM partition on the new Dell XPS 15?

    - by timepilot
    My new Dell XPS 15 L521X just arrived. I need to set this up to dual boot Linux. Sadly, the system comes with four primary partitions. I can't do a clean install at the moment, so one of the partitions will have to be deleted before I can install Linux. The layout is as follows: OEM: 39mb Hibernation: 8gb OS: 457gb Recovery: 12gb Obviously, I can't delete the Hibernation and OS partitions (will shrink to make space for Linux) and I'd like to keep the recovery partition if possible. So my question is what is on the small OEM partition? What functionality will I lose if I delete it?

  • Recover Partition-Table still present in running system

    - by theomega
    Hy, I accidentially overwrote the first 1M of my harddisk on linux (using dd). So, the partition-table is gone. I can still access all partition (except the first one) using /dev/sda2 (and so on), so the data is still there. I only need the partition boundaries to restore the table. How can I do this? The Linux-Kernel must still know them because all mount-points still work. fdisk -l /dev/sda doesn't work because it acctualy reads the partition table. Thanks!

  • How to access both partitions on a bootable USB flash drive in Windows

    - by Maccyjam
    I have a 16GB USB Flash Drive that is partitioned into two different sizes. The first partition contains a bootable version of Ubuntu, the second partition is for general saving of files. Windows will only recognise the first partition. I have tried using Bootice but this breaks the bootable partition. Disk Management recognises the second partition but does not allow me to do anything with it. Is there a way to make both partitions accessible by Windows and keep the USB disk bootable?

  • Unnamed, hidden partitions on my 500 GB HD, HP Pavilion dm4 Laptop

    - by emotionull
    I have multiple doubts here. Its a Seagate 500GB 7200RPM HD. I had installed it few months back after my original Laptop HD stopped working. The current drives on my latop, as shown by the Windows Disk Management are: After installing the new HD, I had done a complete clean install of Windows 7 and I didn't create any parition myself, manually. So there are 4 drives. Even previously, before I installed this new HD, my laptop had 4 Partitions. But the there were no un-named partitions like the two in this case. The other two were HP tools and Recovery or something. It was pre-configured, Factory installed Windows. Also, now when I right cick on the unnamed Drives from Disk Management, all the options are greyed out (see image) except the delete partition image. So how do I know what's inside those partitions? Will it be ok if I delete them? I want install Ubuntu and dual boot it with my current windows installation. I cannot do it in current setup as there are already 4 partitions of my HD and if I will try to make a new partition, it will be a logical one (correct me if I am wrong here). So can I delete the un-named, hidden partitions and use them for Ubuntu? A bit unrelated question. As a backup option, can I use the Windows 7's Backup and Restore facility to keep a complete backup of all the drivers and system softwares.

  • Install Second Copy of Windows in a Partition, Block Access to other Partitions

    - by Mat
    I want to lend my computer to my flatmate so that he can play some games for which his computer is underpowered. Is it possible to install a second copy of Windows 7 into a separate partition and configure it such that it has no access to the other partitions and disks on the computer, the ones that I use in my main Windows install? I'm not concerned about security, just want to avoid him accidentially messing with my data somehow. Can I do that?

  • Multi-partition USB stick

    - by nightcracker
    In my freelance job as "the dude that fixes your computer" I have an extremely handy tool, a bootable USB stick with Ubuntu LiveCD that allows me to recover and investigate in a known, working environment. Now, I want to reformat this USB stick and reinstall with Casper-RW persistance. I did this a few times before with a FAT-formatted USB stick. It was a horror. The USB drive corrupted constantly, by people accidently removing the USB stick, the computer not properly shutting down, ETC. Now what I want to create a multi-partition USB stick so I can put Ubuntu on a ext partition, but still be able to store some Windows stuff in it, by having a secondary FAT partition. However I read somewhere that Windows will only check the first partition on USB sticks, giving a problem with the first bootable linux partition. Is this possible on some way? EDIT Perhaps it wasn't clear what the problem is. The problem is that I read somewhere that Windows will only recognize the first partition on a USB stick. But I want two partitions, a ext partition and a FAT partition. No issues so far, but in order to be bootable the ext partition must be the first one!

  • How can I restore GRUB without a live CD?

    - by Looterguf
    I realize that this is a duplicate of a question asked before, but in that question the asker managed to find his live CD and no real answer appeared, thus I am re-asking it. I managed to screw up my GRUB by deleting two linux partitions on my hard drive from windows. After this, GRUB gives the error "partition not found", and gives me the grub-rescue prompt. The only command I have found to work in this is 'ls', which spits out my partitions. I would use the live CD fix, but I am in India, and all my live CDs are back home in the US... What I've got is an internet connection, a 4GB flash drive with Flow OS installed (which I am currently using but can wipe if need be), and a working laptop that I can borrow. What should I do?

  • WindowsXP+7 on C:/D: :moving the System Partition

    - by user938921
    I had installed Windows 7 on a separate 20gig partition, and I'm absolutely loving it! Plus I can now dual-boot, with my original WinXP residing on the C: drive. But I'm running out of disk space on D:, and I was able to shrink C: and expand D:. But now I would like to make D: not just a Boot Partition, but an Active System Partition, without losing my ability to boot into Windows 7 (since it was created on a separate D: partition, not the current Active System C: Partition). Any advice?

  • SDcard /dev/sdb2 is apparently in use by the system; will not make a filesystem here

  • Recover partition table after DD command

    - by Shreedhar
    I executed the following command from a Ubuntu live cd terminal (dont ask why). dd if=/dev/zero of=/dev/sdb2 bs=512 count=1 Where sdb2 is a NTFS partition (third partition) on a disk. Suffice to say it is now messed up. When I boot into windows 7, it does show me E drive but when I click on it it asks me to format it. I am not ever sure what I did, did I mess up partition table or only the MFT? Is there any way to get the data back PLEASE HELP! this is very important :(

  • How to setup RAID partitions with parted?

    - by psycketom
    I'm going through the https://wiki.archlinux.org/index.php/RAID guide in here, but I'm stuck on Partition Tables. Since my drives are 3TB, fdisk and cfdisk won't cut it due to their 2GB limit, but they are straight forward when managing partitions - adding da or fd as types. But, there is not that straight forward guide for RAID partition setup with parted. So, how do I make Non-FS or RAID partition with parted?

  • Moving from 1 Linux Partition to Many over USB Mount

    - by Mistiry
    We have devices which use Compact Flash for storage. They work OK, but we recently got industrial-grade CF cards to start using. One of the major problems we get is corruption on the flash card. As it is now, these flash cards run Debian with everything in a single partition. We want to have multiple partitions on the new industrial CF cards to help avoid some of the corruption problems. I booted up the device, and attached a USB CF reader. I then used fdisk to partition the CF card in the USB reader. How can I move the data to these partitions so that it works? I have a partition for each of these directories: /lib /var /root /boot /tmp /home /etc / swap space I imagine I can't just use rsync - do I need to attach a second CF reader with a copy of the CF card, so that it's not active and in-use - and then copy from the first reader to the second? How will the system know where to find its files? I know I'd have to change fstab, but that resides in /etc, which will be on a separate partition...how will it find the fstab file if it can't find /etc? And what about grub? I'm at a loss, perhaps its just because I'm under the weather, or I'm just missing a piece of logic here... Any help is greatly appreciated, this is somewhat urgent as our existing stock is nearing its end and we don't want to purchase anything but these industrial cards, but need to get it working with partitions.

  • Is there a software in windows that enables you to boot from a specific partition?

    - by Tono Nam
    I use acronis true image to mount images to my primary partition and it works great. lets say I have 3 partitions on my hard disk and all of them each is 600 GB. In the 3rd partition I keep files (documents, pictures etc), on the first partition is my primary partition where the operating system runs (windows 7). And in the 2nd partition is empty. I have an image of my primary partition and I save that image in my 3rd partition (50 GB is the size of the image so it fits in the partition number 3) and in an external hard drive. I know it is possible to install a new operating system in partition 2 such as windows xp but the only problem is that once I install that how could I tell the computer to boot from partition 1? is there a way to switch back and forth just like it's possible in the mac?

  • Restoring factory recovery partition (samsung)

    I have upgraded the HDD in a Samsung laptop and would like to restore the "Press F4 for recovery" partition. My new disk has three partitions, System, Windows, and Recovery. I did a dd of the recovery partition from the old HDD to the new. I also set the diag flag on the new HDD. F4 recovery still is not working. tldr: I mapped my new disk like my old disk with the exception of exact sizes. I did the recover partition from old to new via livecd. F4 recovery does not work

  • How to move a partition to the end in gparted?

    - by matnagel
    I can't find a way to move the partition /dev/sdb2 to the end, where 12GB are free http://dl.dropbox.com/u/3358699/permanent/gparted-sdb.png I can resize (expand) the partition, but not create (insert) any free space in front of it. How to do the trick? (There are 2 small black arrows on the top of the popup window in the screenshot at the side of the blue box that represents the 400 GB sdb2 - I can only move the right arrow to the right, which extends the size, but I cannot move the left arrow. When I enter something in the free space preceding box it is always reset to zero by the programm immediateley) I hope I explained this well enough, please feel free to ask for details. This is serious for me as I am expanding a live image. Maybe there is another solution with linux commandline tools ?

  • How can I shrink my Windows partition further than the disk management is allowing?

    - by Walkerneo
    I just bought a new computer with a 2tb hard drive that has only a single partition. I would like to divide this into at least 4 partitions, but when I try to shrink the current partition, it says the total size is 1888171 MB and that the size of available shrink space is only 939075 MB. The used disk space is at 40gb right now - why can't shrink it to somewhere around that? I read here: http://www.howtogeek.com/howto/windows-vista/working-around-windows-vistas-shrink-volume-inadequacy-problems/ that this is because of unmovable system files. I doubt this is the only problem though. I would like to get this partition down to 500gb. How can I do this?
