General :: Missing Partition After Installing Ubuntu On External Drive?

Feb 3, 2011

I am keen to start using Ubuntu and have installed it on one of 4 partitions on my new 1 TB external HD. I got to the reboot stage where I was expecting a new boot screen where I could decide to use either XP or Ubuntu. But there is no mention of Ubuntu just XP and the volume I installed Ubuntu on has disappeared. I can find the other 3 volumes on My Computer.

General :: Resize Partition On External Drive

Mar 21, 2009

Computer hardware is not my bag. I accidentally installed ubuntu on external F drive, thinking it was C drive, unaware that ubuntu installs on drive with most available space. Installation involved partitioning the drive in about half. So, before I install it on C drive, I want to restore my F drive. I deleted partition using XP Disk Management tool and tried to use gParted on Parted Magic live boot cd to resize remaining partition that contains my data. But it doesn't seem able to expand the good partition to reclaim the 'unallocated' space. How do I accomplish this? Must I backup and reformat?

General :: IMac Boot From Partition On External Drive?

Apr 3, 2011

I have the following "setup:"

iMac (no internal drive/dead) --------- (Firewire) ------- [[MAC OS X]]
|
|
|[code]...

I routinely use the firewire drive to boot MAC OS X.However, I would like to boot from the linux partition of the USB drive. This linux partition had linux installed on it from a live cd, and during that process, I told the installer to install GRUB on the usb drive (which happened to be /dev/sdd).My question is, how do I get this disk to show up during the iMac option-boot? Currently, only the firewire MAC OS X option shows up. I have read about rEFIT, but that appears to install it to the Mac OS X disk (would that still work?)...Also mentioned was installing rEFIT to the internal EFI system partition, but I don't know if that is wise.

General :: Sharing An Ext3/ext4 Partition On External Drive?

Aug 30, 2011

is there a way of sharing an ext3/ext4 formatted partition on an external USB drive between different users (uids) on different Linux machines without creating a group for this purpose, setting the group ownership of the partition to this group and adding each respective user to the group on every machine?This would mean that I need to have root privileges on every machine... which I may not have in some cases.I'm using the partition to store the code I'm developing on Linux and I would like the option to be safe... if possible.I could use a vfat partition but then I have no control of the rw rights + I cannot develop directly in the dir: I would always have to tar.gz the directory, extract, work, tar.gz, copy to the external drive.

General :: Multiple Distros - One Data Partition - External Drive

Apr 8, 2010

I've got an external hard drive with one large data partition on it. I also have four computers to connect it to (individually, not at the same time). Three machines are running Slackware and one is running Ubuntu 9.10. I need to be able to just plug the drive into whichever machine, mount it (preferably to the same location each time) and not have to worry about user permissions and such. Do I just chmod 777 all the files and folders or is there a better method for different 'users' to access the same partition? And how about mounting to the same location each time?

Now the second part of my question I'm pretty sure I'm not able to do but just in case..... is there any way to encrypt the information safely and make it compatible with a Windows XP machine?

General :: Installing Debian On External (connected Through USB) Hard Drive?

Apr 23, 2011

I've got Vista installed on my notebook and I've bought an external drive (1,5 TB, but its size shouldn't matter in this case) and after formatting it I left 10 gigs for future purpose. Now, I decided to install 64bit debian on the unallocated 10 gigs. And so I did. To be precise: I have SATA drive inside my lap and hard drive (it's also SATA inside the cover) connected to my lap through USB. Boot sequence was 1)CD/DVD 2)hard drive 3)removable drive. During the installation the installer detected my internal drive as /dev/sda and my external drive as /dev/sdb. I decided to install grub on /dev/sdb (it was logical to me, since I didn't want to mess up my regular drive's MBR). Installer created 5 partitions on my USB drive. After booting from my external drive (look below*) I've got a message saying

Code:

error: no such partition Entering rescue mode... and after that I was in grub rescue console. When I typed ls I've got an output

Code:

(hd0) (hd0,msdos1) (hd1) (hd1,msdos5) (hd1,msdos2) (hd1,msdos1)

When I tried to type

Code:

ls (hd0)/

I only got a message

Code:

error: unknown filesystem This occured for all the listed devices... On my internal drive there were (during the installation and running the live cd) 3 partitions detected (vista os, data, rescue disk) so I don't understand the output that ls in rescue console gave me. about booting from external drive: I did that after pressing ESC - I've got a prompt to choose which device I want to boot from - this wasn't working properly; after changing the boot sequence the grub started but with the abovementioned error message...

If there's any info about exact names/types/devices of my installed partitions needed I will run live CD and check it. If any other info is required I will provide it (I tried to describe the problem in the most precise way ) What I was thinking about: maybe there is a problem with ordering of the devices - when I boot from DVD my removable disk is treated as the "second one" and after booting from the removable disk it becames the "first one" or something like that? If any of you have any good info on how mapping of the device names works it would be appreciated, since I couldn't find anything useful or I just don't know what to ask google about.

1) How to install Debian on a removable disk (I had no problems with installing Linux on pendrive but I did that from VirtualBox and it was some time ago) OR how to install GRUB on a removable disk? (unfortunately, I cannot install 64bit system through VirtualBox)

2) What's the logic behind naming devices under /dev? How come the devices in grub have their names mapped as hdx etc and I've read that hdx are the names for IDE/ATA drives and sdx is the proper name for a SATA or USB device

Ubuntu Installation :: Installing 11.04 On External Hard Drive Drive?

Jun 19, 2011

I would like to install Linux Ubuntu 11.04 on an external hard drive - its partitioned and ready for Linux.I've downloaded and burnt the .iso file to a DVD so its all good so far...First of all... is this possible without messing up my macbook? I don't particularly want to break into my macbook to disconnect the hard drive (I read on a tutorial for a previous version of Ubuntu that I'd have to do that... - does it still apply to 11.04?) - as it voids the warranty (I checked ).The reason I ask this is because I had a friend who partitioned their internal hard drive and installed Ubuntu on it. But after installation was complete they couldn't boot up Windows 7 or Ubuntu... and it resulted in them having to clean install Windows 7... - I don't want to end up in that situation

Second... If it is possible to install it without messing up my macbook... - Do I just follow the install instructions but just make sure that where possible I make sure that everything is installed on my external hard drive?...I really need someone to put my mind at rest that everything will run smoothly and that I'll be able to run Mac OS X as usual but also that I'll be able to boot from my external hard drive to run Ubuntu.

Ubuntu :: Files Missing On External Hard Drive

Jul 27, 2010

I have an external harddrive of 500GB. It's almost fully loaded with TV series and movies. Nautilus says there's 60 GB remaining space. I just downloaded some movies, and copied it to this external hard drive.And here's the strange part, after I did this I only see a very small subset of all the movies I stored on that harddrive in nautilus. With 500 GB almost full, you can imagine there are quite some movies on it, but I only see 12 of them in nautilus.

Is there a way to install 11.04 on a external USB drive. I tried the regular install but it will not let me pick the drive, it wants to install on my internal HD. I know I can use Startup disk Creator but It set it up like a install USB and it takes forever to boot up. Also if I use Unetbootin I won't be able to save files to the USB Drive.

Ubuntu Installation :: Installing 9.10 On An External Hard Drive?

Feb 20, 2010

I looked around on these forums and google and came to no solution so, I decided to make this thread. I'm using Windows XP and after I downloaded and tested out Ubuntu 9.10, I decided I'd like it as a second OS, can I install Ubuntu on my external hard drive (1TB)? would installing on an external hard drive take away the risks of losing data etc? If I installed Ubuntu on my external hard drive would it delete any files already on my hard drive?

Ubuntu Installation :: Grub - Installing 10.04 64bit On An External USB Drive

Jul 15, 2010

The default (graphical) installer did not work on my PC (i7 quadcore 8 GB DDR3). I have installed Ubuntu using the alternative installer (Desktop, 64 bit) on my external USB drive. I installed grub on the MBR of the second drive (/dev/sdb) as I did not want to touch my (first) Windows disk. After reboot (chosing the USB drive as boot device, else Windows is booted) grub reports an error and enters the rescue mode. I tried all possible combinations of "root=(hdX,Y)" in grub.cfg to no avail.

I repeated the whole procedure but now disconnected the internal HD with Windows. Installation went smooth again (Windows disk was not seen this time), but after reboot (the internal drive connected or not) I again get (slightly different this time) grub error: can not find file.

Ubuntu Installation :: GRUB2 Not Installing To External Hard Drive?

Aug 9, 2011

I tried doing a search and couldn't find anything relatively recent on the topic so here is my question.

I am fairly new to the linux world and am in the process of trying out a couple different distributions. I am doing this by installing them to an external hard drive. This allows me to test them out without affecting my main system in any way. I have already tried openSUSE and it installed with no problems. I am trying to install Ubuntu, however when the installation tries to install GRUB2 it fails asking me for a different location to install it to.

When installing I unhook all drives from the computer except for the dvd drive, usb drive I'm installing from, and the external hard drive I am trying to install Ubuntu to. I'm not sure what else may be of use.

Software :: Deleted Partition Now External Drive Not Mounting

Mar 27, 2010

My brother has an external hard drive that has some personal data on it that he doesn't want to lose. He was reinstalling windows on his machine and deleted both the partition on his internal drive and on his external drive. He installed windows on his internal drive only though. I want to be able to reaccess that data from the drive. All the data should still be on the drive since so write cycles have been done to overwrite it.

I guess deleting the partition removed the partition table or something so the drive doesnt mount. I would prefer to use linux (but windows is ok too) and a free as in beer tool preferably. there are normal recovery tools (I have used get data back before) that scan for any files anywhere that has been overwritten but I don't really need things that have been overwritten; just the data that is still there but not availible because it cant be mounted.

Ubuntu Installation :: Boot Windows 7 From An External Drive After Installing Lucid

Aug 11, 2010

i currently have lucid installed on my laptop hard drive. i took this drive out and then on a new drive in its place i have installed windows 7. reason why i couldn't put windows 7 on the same drive is that i have a BIOS based system and the hard drive is GPT based not MBR. therefore, i couldn't get windows back on it.

I figured that using an esata expresscard interface i should be able to use the Windows 7 drive externally without much speed penalty since ExpressCard in my case is implemented on PCI Express and not USB.

So i can update grub using
Code:
update-grub

and Windows 7 appears on the list. However, when i select this option during boot, it gives me errors that indicates that the external drive cannot be found (not surprising)

My guess is that when GRUB appears, the external hard drive has not been detected yet, and the modules for the expresscard may only be loaded during the boot process of lucid.

So I am wondering if there is anyway I can get this to work. meaning use lucid on my main drive and boot to Windows 7 from the external drive time to time.

Ubuntu Multimedia :: Installing LinDVD For Toshiba External SuperMulti Drive?

Dec 26, 2010

X-Posted at Hardware & Laptops

I'm having the same problem this guy had. He got an error message when trying to install LinDVD, but since he realized he didn't actually need the software in the first place, the thread is still unsolved.

My computer has no CD/DVD drive. I just got a Toshiba External SuperMulti Drive that I want to use for reading CDs and DVDs. The drive included a CD with LinDVD on it, which I can put into the drive and use to install LinDVD. However, the Package Installer gives me the same status message as CKMBDavis had: Error: Wrong architecture 'lpia'.

I tried just hooking up the drive to my computer and inserting a DVD. It prompted me to open Movie Player, which I did, but when it tried to actually play the DVD, a pop up box came up that said, "An error occurred. Could not read from resource." VLC will not play the DVD either.

Here is my output for print architecture in response to adam814's first comment on CKMBDavis's thread:

Code:
$ dpkg --print-architecture
i386
I also tried adam814's suggestion in his second comment:
Code:
$ dpkg --force-architecture -i <lindvd.deb>
bash: syntax error near unexpected token `newline'

How do I get my DVD player to work?

Ubuntu :: Load Windows Partition Encase The External Hard Drive Fails?

May 14, 2010

I'm new to the ubuntu forums as well as ubuntu. I'm excited to learn more about linux itself as well as ubuntu. I got ubuntu 10.04 running on my toshiba L505D laptop by disabling acpi in the boot commands. My first question is how do i do this permanently, is this bad, and would updating fix the issue? If so how would I go about updating.

Secondly, when the external hard drive I installed ubuntu on is not plugged in to the laptop, GRUB rescue comes up. I kind of like this because it provides a level of hardware security. I would however like to know how to load my windows partition encase the external hard drive fails.

Ubuntu Security :: Ecrypted External Hard Drive Partition Won't Mount Or Unmount?

Nov 15, 2010

I've been running Linux for a year on our family computers (one desktop, one laptop and two netbooks). I've run into a problem with the encrypted ext4 partition (270GB) on a LaCie external hard drive which also has a NTFS partition (50GB) which is not encrypted . First two times I tried using the encrypted ext4 partition (from two different computers) it worked fine but now I can't access it at all. I can still access the NTFS partition.Encrypted external hard drive partition will unlock but won't mount (or unmount). The computer says "Opening 320GB Hard Disk" but after a minute says, "Unable to mount location. DBus error org.freedesktop.DBus.Error.NoReply"Disk utility (GUI for gparted I believe) states that the encrypted partition (/dev/sdb1) is unlocked and the underlying partition (/dev/dm-0) is not mounted but it has a "busy circle sign" on it that will not turn off. The NTFS partition on the same drive mounts and accesses normally.

But if I try to unmount the NTFS partition, it says: "Unable to stop drive. One or more partitions are busy on /dev/sdb"If I try to shut down the computer, it is unable to shut down because (I assume) it can't shut down that drive either. So I have to just turn off the computer.fdisk states that /dev/dm-0 doesn't have a valid partition table [full output attached]fsck suggests: "Filesystem mounted or opened exclusively by another program?"ps axuf shows some processes running on /dev/dm-0 but killinghem doesn't release the drive either. [full output attached]I checked /etc/blkid.tab (suggested in one vaguely related thread) and there's no actual file only a broken link pointing to /dev/.blkid.tab (which doesn't exist). I tried deleting this link and rebooting but that didn't change anything.when I finally gave up my data as lost, I tried to format the partition (using Disk Utility) and it refused saying, "One or more block devices are holding /dev/sdb"

OpenSUSE Install :: New Partition On External Drive - Permissions: Root Drwxr-xr-x?

Apr 21, 2010

I tried two times to make an new partition (after the FAT partition on it) on my external hard drive with YaST>Partitioner.Fist I had tried ext3 now I have ext2 on it.Both times the partition (or the corresponding folder in /media) was only writeable to the superuser/root but not to a normal user (readable to the normal user). Root is the owner.The FAT-Partition on the same external drive is owned by the normal user who was logged in as I plugged the USB-cable in.I can unmount both partitions als normal user in natilus.1. Can I start nautilus as root to change the permissions?2. What have I done wrong? Should I use an SuSE Live-CD or an CD with an special partitioning-program instead?ng X20) openSuse 11.1 and Gnome 2.24.1 (mostly, 1 account is using KDE) and Kernel Linux 2.6.27.45-01.1-pae. "/home" is on an separated partition (as part of an extended partition). I have also 2 NTFS partitions for Windows XP (System and Data), and a FAT, a root (/) and a swarp partition.

Software :: Change Default Noexec To Exec For All Partition In An External Drive

Jan 15, 2010

Whenever I plug an external harddrive to a CentOS system,all partitions mounted will have noexec that makes my binaries or script files not executable.

Quote:

[root@centos52-64-dell ~]# mount
/dev/sda3 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)

[code]....

I have to remount it using, e.g.,

mount -o remount,exec /dev/sdb1

But I am sick and tired of doing it everyday. What I can I do ?I don't want to use /etc/fstab to solve this problem becauseit will cause booting problem (curable though) when the hard drive is not around.

OpenSUSE Hardware :: External SATA Drive Not Recognized / Cant Recreate The Partition On Server?

May 2, 2010

OpenSUSE 11.2 server, Gigabyte GA-MA790X-UD4P sda for system, 3 ext4 partitions, working fine.sdb promise RAID1 for data, 1 ext4 partition, working fine.sdc is an eSATA docking station for data backup, 1 encrypted ext4 partition -- here lies the problem.

This configuration has been functional for months until I decided to add two more external drives (sdc) to rotate through backups. I had difficulty with encyption on the first new drive and eventually decided to start over. Using the gui Yast Expert Partitioner, I deleted the single partition. That began a real nightmare...

Since deleting the partition, the system detects drives inserted in the docking station, but does not report them (including a different fully functional drive and a brand new unused drive). I have tested all drives on other computers and they function perfectly. I have rebooted the system several times while troubleshooting this issue.

Could not recreate the partition on server (since it does not recognize the drive), so I used Gparted on another computer - it all went without a hitch, formatted ext4. But when I placed the drive in the dock, the drive still was detected but not recognized.

Details:

BIOS lists the eSATA drive

Entering Yast Expert Partitioner, error message follows:

The partitioning on disk /dev/sdc is not readable by the partitioning tool parted, which is used to change the partition table.

You can use the partitions on disk /dev/sdc as they are. You can format them and assign mount points to them, but you cannot add, edit, resize, or remove partitions from that disk with this tool.

Yast partitioner shows drives: sda, sda1, sda2, sda3, sdb, sdb1 sbc is not listed.

# fdisk sdc results in: Unable to open sdc
# dmesg | grep tail reports:
[48442.370779] sd 0:0:0:0: [sdc] Unhandled error code
[48442.370793] sd 0:0:0:0: [sdc] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
code....

So how did partition deletion cause this issue, and how do I correct the problem? It is possible that my difficulties encrypting the first new drive are related (it's not my first time doing it successfully). It seems the problem is in the Kernel or configuration. I have invested many hours in forums and on google - tried dozens of possible fixes. I'm beginning to suspect system corruption or a bug, however all other system functions are working perfectly.

Ubuntu :: Partition Virtual Drive Before Installing Operatin Systems

Aug 13, 2010

I have an acer laptop (TravelMate 7320) which came with Windows Vista. I have made copies of the recovery disk for vista and installed Ubuntu 10.04 and would like to run Vista from a virtual machine in Ubuntu and for this purpose I installed Virtualbox. The problem is that the recover disk that acer provide require the hard drive to partitioned in a certain way otherwise the installation process error outputting "No partition available".

Acer do provide a bootable CD for download from there website to partition the drive before installing from their recovery disk but I have tried this with virtual box and the process doesn't detect the virtual drive. So my question is does anyone know of a virtualisation software for Ubuntu that they could recommend that allow for the partitioning of virtual disk before the installation of an OS? Or even better does anyone know how to do this with Virtualbox?
