  • GParted in UBUNTU shows entire disk as UNALLOCATED SPACE

    - by msPeachy
    Good day to everyone. I hope someone can help me with my problem. I have a dual boot Windows and Ubuntu system. I recently encountered an hd0 out of disk error and wasn't able to boot Ubuntu. So I booted into Windows, after 2 to 3 times of booting and rebooting Windows, I tried booting Ubuntu but still I get the hd0 out of disk error. I decided to run Ubuntu from LIVEUSB to try to fix my Ubuntu partition using GParted, but when I run GParted, it shows my entire disk as UNALLOCATED SPACE! The strange thing is that Nautilus still shows and mounts my partitions. Also every time I boot into Windows , my partitions exists and I am able to read and write to them. I have no idea what is wrong. Please help! I can't stand using Windows since most of the tools I use are in Ubuntu. I don't mind reinstalling Ubuntu. In fact I already tried reinstalling using the LIVEUSB but I wasn't able to, since GParted or the Ubuntu installer itself does not recognized my partitions and shows the entire disk as unallocated space. I am currently running Ubuntu from LIVEUSB. Here's the outpuf of sudo fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 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 Disk identifier: 0xb30ab30a Device Boot Start End Blocks Id System /dev/sda1 * 2048 104869887 52433920 83 Linux /dev/sda2 104869888 105074687 102400 7 HPFS/NTFS/exFAT /dev/sda3 105074688 156149759 25537536 7 HPFS/NTFS/exFAT /dev/sda4 156151800 625153409 234500805 f W95 Ext'd (LBA) /dev/sda5 156151808 169156591 6502392 82 Linux swap / Solaris /dev/sda6 169158656 294991871 62916608 7 HPFS/NTFS/exFAT /dev/sda7 294993920 471037944 88022012+ 7 HPFS/NTFS/exFAT /dev/sda8 471041928 625121152 77039612+ 7 HPFS/NTFS/exFAT When I run, sudo parted -l, I got this error message: ubuntu@ubuntu:~$ sudo parted -l Error: Can't have a partition outside the disk!

  • Ubuntu installation does not recognize drive partinioning

    - by Woltan
    I have a 1TB drive and installed Windows 7 on a 128GB partition. When I now try to install Ubuntu 11.04 it does not recognize the Windows partition but offers the complete 1TB drive to install Ubuntu on instead. It displays: However, in the Ubuntu Disk Utility the Windows partitions are recognized. What do I need to do in order for Ubuntu to recognize the Windows 7 partition and install Ubuntu as a dual boot? Response to comments The following commands were executed and the results are shown below: fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT.

  • Why does Ubuntu 13.10 not detect my Win7 partition?

    - by goutham
    I'm trying to install Ubuntu 13.10 alongside Windows 7 on my DELL INSPIRON 14z 5423 laptop and I'm new to all of this. I'm using the Ubuntu 13.10 64-bit ISO burned onto a CD. The first time I tried to install it, Ubuntu said it did not detect any other OS, which meant I only had 4 options: Erase disk and install Ubuntu (I don't want to do this) Encrypt new Ubuntu. Use LVM. Something else. If I choose the Something else option, it brings me to the partition menu and says that I have 1 disk with free space of (500Gb), but that's not true because I have Windows 7. I restarted the laptop several times and booted the CD again and I got exactly the same as I did previously. How do fix this problem and install Ubuntu alongside Windows 7? After executing "sudo fdisk -l" command in terminal ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

  • How to use Secure Erase and is it on the install CD?

    - by Mikey
    Supposedly there is some built in hard drive magic called "Secure Erase" which is wildly faster and more secure than "dd if=/dev/zero..." I am most excited about the speed increase. There seems to be a GUI for it as part of Parted Magic: http://www.ocztechnologyforum.com/forum/showthread.php?81321-Secure-Erase-With-bootable-CD-USB-Linux..-Point-and-Click-Method Is there something like this for Ubuntu? Better yet, is there a way to actually issue this command "manually" like with smartctl or something?

  • Weird Ubuntu Desktop Boot Partition On External Hard Drive

    - by Magnitus
    I have a Thinkpad with Windows 7. Last time I installed an Ubuntu/Windows dual boot, Windows was never same after and regularly got corrupted so this time, I installed Ubuntu on a separate external hard drive. I took a 500 GB external hard drive and used Windows to shrink the partition on it to 400 GB, freeing 100 GB to install Ubuntu. Then I modified the booting priority of my computer to boot from the external hard drive if present. Then, I installed Ubuntu desktop on the external hard drive using a DVD, picked the most simplistic partitioning scheme I could get away with (didn't go auto as it didn't include the external hard drive as a choice) and voilà. Fast forward some time and I'm trying to refresh my understanding of Linux partitions to install a bunch of servers, so I'm looking at the current partitioning scheme on my external hard drive and find the boot partition puzzling... sda is my integrated hard drive with Windows 7. sdb is my Ubuntu desktop external hard drive. Running parted on sdb, I get this: (parted) print Model: WD My Passport 0740 (scsi) Disk /dev/sdb: 500GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 393GB 393GB primary ntfs boot 2 393GB 500GB 107GB extended 5 393GB 425GB 32.8GB logical linux-swap(v1) 6 425GB 500GB 74.6GB logical ext4 At this point, I'm wondering why the ntfs partition is flagged as "boot" and not my ext4 partition which is the partition that contains / (and by extension, /boot since it's not on its own separate partition). Looking at mtab only confirms what I already know: eric@eric-ThinkPad-W530:~$ sudo cat /etc/mtab /dev/sdb6 / ext4 rw,errors=remount-ro 0 0 proc /proc proc rw,noexec,nosuid,nodev 0 0 sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0 none /sys/fs/cgroup tmpfs rw 0 0 none /sys/fs/fuse/connections fusectl rw 0 0 none /sys/kernel/debug debugfs rw 0 0 none /sys/kernel/security securityfs rw 0 0 udev /dev devtmpfs rw,mode=0755 0 0 devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0 tmpfs /run tmpfs rw,noexec,nosuid,size=10%,mode=0755 0 0 none /run/lock tmpfs rw,noexec,nosuid,nodev,size=5242880 0 0 none /run/shm tmpfs rw,nosuid,nodev 0 0 none /run/user tmpfs rw,noexec,nosuid,nodev,size=104857600,mode=0755 0 0 none /sys/fs/pstore pstore rw 0 0 systemd /sys/fs/cgroup/systemd cgroup rw,noexec,nosuid,nodev,none,name=systemd 0 0 gvfsd-fuse /run/user/1000/gvfs fuse.gvfsd-fuse rw,nosuid,nodev,user=eric 0 0 /dev/sdb1 /media/eric/My\040Passport fuseblk rw,nosuid,nodev,allow_other,default_permissions,blksize=4096 0 0 My lack of understanding concerning this is not vital to anything (this is only my development desktop partition), but somehow annoys me. Any insight that could shed some light on this would be welcome.

  • Ubuntu 10.04 preseed unattended install results in faulty partition table

    - by joschi
    I'm currently trying to set up an unattended installation of Ubuntu 10.04 (Lucid Lynx) through preseeding. But whenever I try to create a custom partition scheme, the Debian installer (which Ubuntu is using) produces a faulty partition table. I've taken the partition scheme described in the example preseed file: d-i partman-auto/expert_recipe string \ boot-root :: \ 40 50 100 ext3 \ $primary{ } $bootable{ } \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ /boot } \ . \ 500 10000 1000000000 ext3 \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ / } \ . \ 64 512 300% linux-swap \ method{ swap } format{ } \ . Unfortunately it also produces an incorrect partition table on the disk. The installation process itself is working and the installed system eventually boots and is working, as far as I can tell. But fdisk and cfdisk are still complaining: # fdisk -l /dev/sda Disk /dev/sda: 17.2 GB, 17179869184 bytes 255 heads, 63 sectors/track, 2088 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000a1cdd Device Boot Start End Blocks Id System /dev/sda1 * 1 5 37888 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 5 2089 16736257 5 Extended /dev/sda5 5 2013 16121856 83 Linux /dev/sda6 2013 2089 613376 82 Linux swap / Solaris cfdisk even refuses to start at all: # cfdisk /dev/sda FATAL ERROR: Bad primary partition 1: Partition ends in the final partial cylinder parted on the other hand does not complain about the cylinder boundary of /dev/sda1: # parted /dev/sda p Model: VMware Virtual disk (scsi) Disk /dev/sda: 17.2GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 39.8MB 38.8MB primary ext4 boot 2 40.9MB 17.2GB 17.1GB extended 5 40.9MB 16.5GB 16.5GB logical ext4 6 16.6GB 17.2GB 628MB logical linux-swap(v1) Since the installed system is working, it shouldn't be a big problem but I'm afraid that this will mean trouble in the future.

  • How to fix: Ubuntu 12.04 reboots after loading with elilo

    - by Casey
    I have an HP p6-2120 with CPU: AMD A6-3620 APU with Radeon Graphics RAM: 6GB BIOS: HO2_710.ROM v7.10 [AMI v7.10 4/19/2012] Disk: SATA1 (/dev/sda) - 1 TB (windows) Disk: SATA2 (/dev/sdb) - 1 TB partitioned using "parted -a optimal /dev/sdb" as follows: .. 1049KB 201MB FAT32 boot flag set .. 201MB 60GB ext2 (/) .. 68GB 78GB linux-swap(v1) (swap) .. 78GB 790GB ext4 (/home) .. - rest is "free" space reserved for other purposes (eventually) ubuntu: 12.04.1 LTS [specifically: Release 12.04 (precise) 64-bit] kernel: linux 3.2.0-29-generic I created a bootable EFI USB from the ISO (64-bit) which I downloaded. I can run and install from the USB without any problems. The BIOS is an EFI bios that appears to be capable of booting in either EFI or Legacy mode. Initially, I did the "standard" install with NOTHING on disk2, and let the installer configure everything. The net result of this was that when I started the computer and forced it into "boot" menu mode, it DOES NOT recognize SATA2 as an EFI drive, and when I attempt to "legacy" boot from it, I get the message "ERROR: No Boot Disk has been detected." The "standard" install created one large partition that consumed the entire disk. At that point, I manually partitioned the disk (using sudo parted -a optimal /dev/sdb) as described above. I selected the "other" install, and changed the /dev/sdb1 to "bios_grub", /dev/sdb2 as "/" (ext4), /dev/sdb3 as swap, and /dev/sdb4 as "/home". [Note: fearing that possibly elilo did not recognize ext4, I switched /dev/sdb2 to ext2 and re-insalled] The net result was that the install appeared to trash the /dev/sdb1 partition so that it was NOT readable by anything. I re-formated /dev/sdb1 as FAT32 and set the boot flag. I repeated the install ignoring the messages about no bios_grub partition. After several attempts to get GRUB2 to work, I switched to elilo. I downloaded the most recent version and copied it (elilo-3.14-ia64.efi) to /dev/sdb1/efi/boot/bootx64.efi. (The BIOS boot loader did not recognize it either as elilo-3.14.ia64.efi or as elilo.efi. Based on the advice in one of the web-pages I found, I renamed it to bootx64.efi. This worked.) In that same directory (/efi/boot), I copied the file pointed to the link in /dev/sdb2/vmlinuz to /efi/boot/vmlinuz, and the file pointed to the link in /dev/sdb2/initrd.img to /efi/boot/initrd.img. I created an elilo.conf file as follows: timeout=5000 prompt default=linux-boot image=vmlinuz label=linux-boot read-only initrd=initrd.img root=/dev/sdb2 The /efi/boot directory contains 4 files: bootx64.efi elilo.conf vmlinuz initrd.img When I power-cycle the computer and force the boot menu, drive2 shows up as an EFI bootable drive. When I select it, I get the elilo prompt. Pressing , it appears to load the kernal (I have tried it with verbose=5, and there is a long string of messages with the final one a command line to load the kernel and a series of several dots that fly by) then the screen goes blank, and it reboots the computer. [Note: I have also tried substituting the UUID as found in the /etc/fstab of the installed system for the root directory. This had no effect.] This is a brief synopsis of several nights of fiddling with this. I would deeply appreciate any help you can give.

  • OCZ Vertex 2 not recognized by Ubuntu installer

    - by Zsub
    As I boot into the Ubuntu 10.10 (or 11.04, doesn't matter) live environment or installer, it just refuses to recognise my Vertex 2. It reports the disk as ATA and not supporting smart, shows no serial number, and doesn't list the size correctly. All fdisk tells me is Unable to read /dev/sda (it's the only storage in the PC). I'm now running a temporary install of Windows 7 off of it, which worked like a charm, so where am I going wrong with Ubuntu... Specs: Asus M4N68T-M LE V2 (BIOS 0702, most recent) OCZ Vertex 2 SSD 60 GB Amd Athlon II X4 640 Patriot PSD34G13332 4GB DDR3 ram (two banks) EDIT I installed a second drive, installed Ubuntu on that and booted, it recognised the SSD just fine. I'm now trying to apt-get upgrade the live-environment. I wonder if there is any way to sort of install Ubuntu from Ubuntu (I boot into the working install on the other drive, install it on the SSD and then boot from the SSD). EDIT2 Ok, so that doesn't work. The install detects the SSD, however, it cannot format it. EDIT3 After a fresh boot I can read out SMART-data and even perform a read-benchmark, but if I try to format it, or do a write-bench, it'll crap out and after that it says SMART is not supported. So basically it seems I can't write to the disk, as it will stop working when I do, I will try to run repeated read-benchmarks to see if that has any effect. EDIT4 I'm running several read benchmarks on the drive right now, they give results that are to be expected from an SSD. If the read-benches don't fail, I can use fdisk on the disk, but it is now stuck trying to re-read the partition table after issueing the 'w' command. EDIT5 Parted Magic did recognize the drive and with hdparm -I even could tell me the drive was in a frozen state. I powercycled it (just pull out the plug from the SSD and plug it back in) and it wasn't frozen anymore. After that I could upgrade the firmware on the drive (still using Parted Magic) and format it to Ext4. After I rebooted into the Ubuntu installer, it wouldn't get recognized and hdparm didn't want to talk to it saying HDIO_DRIVE_CMD(identify) failed: Invalid exchange. EDIT6 For some reason if I enable one of the RAID controllers (the one the SSD is connected to, obviously) Ubuntu will let me format it, mount it and write to it. The installer also recognizes it. However if the raid controller is enabled but no array is defined the motherboard can't boot from it :(

  • Quantifying the effects of partition mis-alignment

    - by Matt
    I'm experiencing some significant performance issues on an NFS server. I've been reading up a bit on partition alignment, and I think I have my partitions mis-aligned. I can't find anything that tells me how to actually quantify the effects of mis-aligned partitions. Some of the general information I found suggests the performance penalty can be quite high (upwards of 60%) and others say it's negligible. What I want to do is determine if partition alignment is a factor in this server's performance problems or not; and if so, to what degree? So I'll put my info out here, and hopefully the community can confirm if my partitions are indeed mis-aligned, and if so, help me put a number to what the performance cost is. Server is a Dell R510 with dual E5620 CPUs and 8 GB RAM. There are eight 15k 2.5” 600 GB drives (Seagate ST3600057SS) configured in hardware RAID-6 with a single hot spare. RAID controller is a Dell PERC H700 w/512MB cache (Linux sees this as a LSI MegaSAS 9260). OS is CentOS 5.6, home directory partition is ext3, with options “rw,data=journal,usrquota”. I have the HW RAID configured to present two virtual disks to the OS: /dev/sda for the OS (boot, root and swap partitions), and /dev/sdb for a big NFS share: [root@lnxutil1 ~]# parted -s /dev/sda unit s print Model: DELL PERC H700 (scsi) Disk /dev/sda: 134217599s Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 63s 465884s 465822s primary ext2 boot 2 465885s 134207009s 133741125s primary lvm [root@lnxutil1 ~]# parted -s /dev/sdb unit s print Model: DELL PERC H700 (scsi) Disk /dev/sdb: 5720768639s Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 34s 5720768606s 5720768573s lvm Edit 1 Using the cfq IO scheduler (default for CentOS 5.6): # cat /sys/block/sd{a,b}/queue/scheduler noop anticipatory deadline [cfq] noop anticipatory deadline [cfq] Chunk size is the same as strip size, right?

  • Clonezilla restore from Samba - no 'restoredisk' option

    - by MT_Head
    I used a CloneZilla LiveCD to back up a couple of Windows machines to a Samba share. Now I'm trying to restore those images, and CloneZilla won't even give me the 'restoredisk' or 'restorepart' options on the menu. I'm guessing that this is because CZ isn't recognizing a valid image... but why? Here's a listing of the folder on the Samba share: -rwxrwxrwx 1 marc users 319 May 31 03:45 blkdev.list -rwxrwxrwx 1 marc users 5307 May 31 04:41 clonezilla-img -rwxrwxrwx 1 marc users 4 May 31 04:31 disk -rwxrwxrwx 1 marc users 16091 May 31 04:31 Info-dmi.txt -rwxrwxrwx 1 marc users 11029 May 31 04:31 Info-lshw.txt -rwxrwxrwx 1 marc users 1502 May 31 04:31 Info-lspci.txt -rwxrwxrwx 1 marc users 170 May 31 04:31 Info-packages.txt -rwxrwxrwx 1 marc users 80 May 31 04:41 Info-saved-by-cmd.txt -rwxrwxrwx 1 marc users 10 May 31 04:31 parts -rwxrwxrwx 1 marc users 2097152000 May 31 04:06 sda1.ntfs-ptcl-img.gz.aa -rwxrwxrwx 1 marc users 247361656 May 31 04:08 sda1.ntfs-ptcl-img.gz.ab -rwxrwxrwx 1 marc users 823182034 May 31 04:31 sda2.ntfs-ptcl-img.gz.aa -rwxrwxrwx 1 marc users 36 May 31 03:45 sda-chs.sf -rwxrwxrwx 1 marc users 31744 May 31 03:45 sda-hidden-data-after-mbr -rwxrwxrwx 1 marc users 512 May 31 03:45 sda-mbr -rwxrwxrwx 1 marc users 315 May 31 03:45 sda-pt.parted -rwxrwxrwx 1 marc users 285 May 31 03:45 sda-pt.parted.compact -rwxrwxrwx 1 marc users 259 May 31 03:45 sda-pt.sf (I've been experimenting with various permissions trying to get this to work; that's why they're currently all "rwxrwxrwx"...) I've got my CZ LiveCD stuck in a (different) machine with a 160GB SATA disk that I'm fine with overwriting; although CZ doesn't show a directory listing, it does show that the correct folder is mounted as /home/partimag. But a moment later, after selecting either Beginner or Expert, I'm only presented with the "savedisk", "saveparts", and "exit" options. What am I doing wrong? I am confident that the initial backup was successful; I can post the log if desired, or any other information that might be germane. Edit: I've copied the contents of the folder onto a 16GB USB stick and set THAT as /home/partimag. Still nothing. What the hell is CZ looking for?

  • Creating a USB stick for installing centos 6.x using DVD1 and DVD2 iso files

    - by user250563
    First, we create 2 partitions on the USB stick that is let's say 16GB. first partition is let's say only 1GB and the second partition is the rest of what is available. after we "w" write the changes, the USB now has 2 partitions. 1 is 1GB 1 is more than 14GB so , we have... sdb1 and sdb2 now. now we need to turn these partitions into filesystems some say i should run these commands after those procedures. mkfs.vfat -F 32 /dev/sdb1 mkfs.ext3 /dev/sdb2 but some web pages recommend using: mkfs.vfat -n BOOT /dev/sdb1 mkfs.ext2 -m 0 -b 4096 -L DATA /dev/sdb2 which is it? so let's say the DVDs are called: CentOS-6.4-x86_64-bin-DVD1.iso CentOS-6.4-x86_64-bin-DVD2.iso so we make a directory: mkdir -p /mnt/dvd1 and then mount it: mount -o loop CentOS-6.4-x86_64-bin-DVD1.iso /mnt/dvd1 and i suppose we don't make a directory for dvd2 and we don't have to mount it ? at this point i do not know what should be done. but i think this step might be next: we make the USB bootable by finding the file named mbr.bin and then moving it to there via these commnad. dd conv=notrunc bs=440 count=1 if=/usr/lib/syslinux/mbr.bin of=/dev/sdb parted /dev/sdb set 1 boot on in other words we are "dd-ing it to 'sdb' not sdb1' or 'sdb2'. and then we use parted to set the boot to on for sdb so far everything looks good? here is the confusing parts.. how exactly do i move these iso files to the usb drive? EVERYTHING BELOW IS A GUESS. so at this point i should copy the folder /mnt/dvd1/isolinux to usb's sdb1 or sdb2 ? rename it to syslinux ? and then inside this syslinux folder there will be a file called... isolinux.cfg ? which should be renamed to syslinux.cfg ? and then copy the contents of /mnt/dvd1/images/* to USB's sdb2 ? but i think i am also suppose to copy and paste the both CentOS-6.4-x86_64-bin-DVD1.iso CentOS-6.4-x86_64-bin-DVD2.iso somewhere into this USB's sdb2 partition, correct ? almost like a drag and drop kind of a thing? or do they go into any folders ? centos' own web site has some instructions but those instructions do not work. http://wiki.centos.org/HowTos/InstallFromUSBkey i once got this working but things got ruined, i have to do it again and this time take notes.

  • My new Intel X25-M G2 and the alignment thingy

    - by Oli
    I just bought a new SSD for my laptop, which is going to be a server running ArchLinux with grub2, GPT and btrfs. My layout should look like this: (grub-partition?) /boot ext2 75MB / btrfs 15GB /home btrfs remaining What do I need to do to create these partitions in a correctly aligned fashion using parted? Do I need to consider alignment when formatting each partition with the desired file system?

  • ZFS - how to partition SSD for ZIL or L2ARC use?

    - by ewwhite
    I'm working with a Sun x4540 unit with two pools and newly-installed ZIL (OCZ Vertex 2 Pro) and L2ARC (Intel X25-M) devices. Since I need to keep these two pools in the near-term, I'd like to know how to partition these devices to serve both pools of data. I've tried format, parted and fdisk and can't quite seem to get the right combination to generate recognizable partitions for zpool add. The OS in this case is NexentaStor, but I will also need this for general OpenSolaris solutions.

  • How to create NTFS partition in Linux to install Windows 7 from USB?

    - by Michal Stefanow
    I messed up with my computer and need help. Generally: install Windows 7 from USB. Problem: "setup was unable to create a new system partition" When first attempt to install Windows 7 failed I tried Linux live USB, installed distro to HDD, and erased all the existing partitions. Current state (fdisk -l): [writing from other computer so no copy and paste] /dev/sda1 305GB Linux /dev/sda2 7GB Extended /dev/sda5 7GB Linux Swam / Solaris To create a new, NTFS partition: fdisk /dev/sda n (for new) p (for primary) 3 (for partintion number) "No free sectors available" All the HDD was formatted couple of minutes before so there is a lot of free space but how to resize a parition? I cannot find an option for resizing in man fdisk. Some people say I should use gparted but my distro doesn't not contain this package. And my distro doesn't support wireless drivers so I have serious problems with downloading stuff. I tried also using cfdisk but any command results in: "cfdisk bad primary partition 1 partition ends in the final partial cylinder" I tried also removing partition 1 and then creating a new one (so there is no "no free sectors"). I'm receiving a warning: "Re-reading the partition table failed with error 16: Device or resource busy. The kernel still uses the old table. The new table will be used at the next reboot." After restating: "grub rescue, no known filesystem" It may indicate that some changes have been made BUT when running Windows 7 installed some another error: "Windows cannot be installed to Disk 0 Partition 1" More detailed: "Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS." So formatting drive using Windows 7 installer BUT this time yet another error: "Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information" Apparently I cannot access logs (how?) and I am back to drawing board with my live USB (this time showing partition as HPFS/NTFS). Any suggestions how to install Windows 7? Should I reinstall Linux to HDD, erase existing partitions once again, and use Parted rather than gparted (parted is included in the distro). Or maybe should I create another bootable USB such as PartedMagic to painlessly create partitions? I just want to install Windows 7 from USB, my laptop is semi-operational and I am ready to receive some help regarding fdisk and creating NTFS partitions. UPDATE: I did as suggested (removed all the partitions) and tried to install in unallocated space. Tried to create a new partition and format it. Same error: "setup was unable to create a new system partition" Came to the conclusion it may have something to do with TrueCrypt I have recently installed. Right now trying to FIX MBR (as I haven't got possibility to create rescue disc without optical drive)

  • Look after your tribe of Pygmies with Java ME technology

    - by hinkmond
    Here's a game that is crossing over from the iDrone to the more lucrative Java ME cell phone market. See: Pocket God on Java ME Here's a quote: Massive casual iPhone hit Pocket God has parted the format waves and walked over to the land of Java mobiles, courtesy of AMA. The game sees you take control of an omnipotent, omnipresent, and (possibly) naughty deity, looking after your tribe of Pygmies... Everyone knows that there are more Java ME feature phones than grains of sand on a Pocket God island beach. So, when iDrone games are done piddlying around on a lesser platform, they move over to Java ME where things are really happening. Hinkmond

  • Rejoining two partitions

    - by Alex
    I was courious about Ubuntu so I decided I would give it a chance, therefore I installed it on a parition on my harddrive. Now a couple of months later I haven't used windows once so i decided to go with ubuntu only. I deleted my windows partition with GParted and thought that it was all good. BUT the now formated diskspace that used to be home to windows is now only a formated partition. How do I connect it to the partition where my ubuntu installation lays iow go back to having a non parted hard drive?

  • Disk drive won't let go of password prompt at bootup?

    - by user54003
    I had a hacker intrude into my system, at the time it was obvious, so I reinstalled. However, I am left with what appears to be a fatal problem as far as one of my disk drives goes. When I install that drive in my system, a prompt comes up for the disk password, and what it is asking for is a root password. The disk works otherwise normally but despite all my efforts, I have not been able to fix this disk. I have gotten the operating system parted magic and done the most extreme clean up available, the internal one which sends a signal to the disk electronics which runs a built in clean up program. Darik's boot and nuke, I've tried them all but I can't seem to remove this with anything in the Linux line. Does anyone have any suggestions? I've run gparted, created a Sun, an Apple and various other schemes to partition the disk, all to no avail. Can anyone help?

  • No device file for partition on logical volume (Linux LVM)

    - by Brian
    I created a logical volume (scandata) containing a single ext3 partition. It is the only logical volume in its volume group (case4t). Said volume group is comprised by 3 physical volumes, which are three primary partitions on a single block device (/dev/sdb). When I created it, I could mount the partition via the block device /dev/mapper/case4t-scandatap1. Since last reboot the aforementioned block device file has disappeared. It may be of note -- I'm not sure -- that my superior (a college professor) had prompted this reboot by running sudo chmod -R [his name] /usr/bin, which obliterated all suid in its path, preventing the both of us from sudo-ing. That issue has been (temporarily) rectified via this operation. Now I'll cut the chatter and get started with the terminal dumps: $ sudo pvs; sudo vgs; sudo lvs Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Scanning for physical volume names PV VG Fmt Attr PSize PFree /dev/sdb1 case4t lvm2 a- 819.32G 0 /dev/sdb2 case4t lvm2 a- 866.40G 0 /dev/sdb3 case4t lvm2 a- 47.09G 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" VG #PV #LV #SN Attr VSize VFree case4t 3 1 0 wz--n- 1.69T 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all logical volumes LV VG Attr LSize Origin Snap% Move Log Copy% Convert scandata case4t -wi-a- 1.69T Wiping internal VG cache $ sudo vgchange -a y Logging initialised at Sat Jan 8 11:43:14 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" 1 logical volume(s) in volume group "case4t" already active 1 existing logical volume(s) in volume group "case4t" monitored Found volume group "case4t" Activated logical volumes in volume group "case4t" 1 logical volume(s) in volume group "case4t" now active Wiping internal VG cache $ ls /dev | grep case4t case4t $ ls /dev/mapper case4t-scandata control $ sudo fdisk -l /dev/case4t/scandata Disk /dev/case4t/scandata: 1860.5 GB, 1860584865792 bytes 255 heads, 63 sectors/track, 226203 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00049bf5 Device Boot Start End Blocks Id System /dev/case4t/scandata1 1 226203 1816975566 83 Linux $ sudo parted /dev/case4t/scandata print Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/case4t-scandata: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 1861GB 1861GB primary ext3 $ sudo fdisk -l /dev/sdb Disk /dev/sdb: 1860.5 GB, 1860593254400 bytes 255 heads, 63 sectors/track, 226204 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000081 Device Boot Start End Blocks Id System /dev/sdb1 1 106955 859116006 83 Linux /dev/sdb2 113103 226204 908491815 83 Linux /dev/sdb3 106956 113102 49375777+ 83 Linux Partition table entries are not in disk order $ sudo parted /dev/sdb print Model: DELL PERC 6/i (scsi) Disk /dev/sdb: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 880GB 880GB primary reiserfs 3 880GB 930GB 50.6GB primary 2 930GB 1861GB 930GB primary I find it a bit strange that partition one above is said to be reiserfs, or if it matters -- it was previously reiserfs, but LVM recognizes it as a PV. To reiterate, neither /dev/mapper/case4t-scandatap1 (which I had used previously) nor /dev/case4t/scandata1 (as printed by fdisk) exists. And /dev/case4t/scandata (no partition number) cannot be mounted: $sudo mount -t ext3 /dev/case4t/scandata /mnt/new mount: wrong fs type, bad option, bad superblock on /dev/mapper/case4t-scandata, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so All I get on syslog is: [170059.538137] VFS: Can't find ext3 filesystem on dev dm-0. Thanks in advance for any help you can offer, Brian P.S. I am on Ubuntu GNU/Linux 2.6.28-11-server (Jaunty) (out of date, I know -- that's on the laundry list).

  • Reconfigure RAID on Dell PowerEdge T710

    - by Stefano Borini
    I have a Dell PowerEdge T710 under my feet at this very moment, with RedHat Enterprise Server 5.3. I have 6 1TB disks and two 500GB. parted reports two devices, one 500 GB and the other 4 TB. So I assume the RAID has been setup as mirror for two disks, and I assume as RAID 5 the remaining ones. I say "I assume" because it does not make sense. Having 6 disks in RAID 5, I should obtain a total space of 5 TB, not 4TB. It's not even RAID 10: I would end up with a 3 TB unit. How can I check and eventually modify the RAID array definition? In the Fujitsu Siemens I played with some time ago, at boot I had the chance to enter the controller BIOS, but here I don't see a clear way to perform this operation.

  • Partition error being reported by only some programs

    - by Mahmoud20070
    I am getting an error about the partitions on one of my drives. I checked my hard disk with Acronis Disk Director 11 Home, HDTunePro, MiniTool Partition Wizard, Hddscan, HDD Regenerator 2011, WD Data Lifeguard Diagnostics, GParted, and Parted Magic, but none of them found any problems with the drive. However, when I perform a check with PartitionGuru, DiskGenius, and an old version of Partition Magic (8.0), I get the following error (seen below) about the partition being bad and needing to reformat to fix it: Error - The number of sectors record in DBR overflow - Reformat Should I reforamt or not? I checked two other hard drives, one of them like my 500 WD Blue, and neither has any errors with any progras. Are there any other programs that can check partitions for errors? Finally, how should a large SATA hard disk be formatted? I currently use programs like GParted, Acronis Disk Director, or MiniTool Partition Wizard. Are these programs good for formatting a new hard disk? Could the choice of format tool be the cause of the error?
