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?

I need to make my root partition bigger to add more free space. Is there a Linux version that will fit on a small usb flash drive that has the tools I need? I plan to boot a Linux distro from a flash drive in order to resize the partition.

I have an external drive with lots of photos on. I want to resize them and someone suggested using Code: for f in *.jpg; do convert "$f" -resize 640x480 -strip -quality 86 "$f"; done Then I realised I don't know how to cd to an external drive. The drive shows up as "Iomega HDD" in Nautilus. I tried every variation I could think of including creating a mount point on my home partition.

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.

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.

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?

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.

When I load the disk I can view my backup drive properly but when I try to view my working drive it shows it as being empty. I also noticed that I had a 1 mg unallocated partition at the beginning followed by my ubuntu partition.
I then ran gparted in terminal and it did show the partition as having my system on it but I am not able to perform any tasks. No moving or resizing.

I just bought a new external 1 TB HP hard drive that came with two partitions.One larger for storage and another 700 MB partition called hplauncher as a sub-file of what shows as a CD drive called HP virtual CD 4607 which held files for windows automatic back up. Which I don't need.Both the CD and launcher drives do not allow for deletion or formatting. The larger drive does.I am viewing it in the Palimpsest Disk Utility that cam with my Ubuntu 9.10 clean install.

Been using a SeaGate FreeAgent external drive for past 6 months. Suddenly the ext2 partition (/dev/sdb2) won't mount, while the NTFS partition (/dev/sdb1) does.I've been allowing automount, no entry in /etc/ fstab.When the NTSF partition mounts there appears an entry

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.

I need to resize a NTFS partition in a disk for which I have an image (dumped with dd).
I mounted it through the loop device on linux:
# losetup -o 32256 /dev/loop0 disk.img # I got the offset from looking at fdisk's output
# mount /tmp/t /dev/loop0
# ls /tmp/t
[content of NTFS partition shows correctly]
# umount /tmp/t
# gparted /dev/loop0
gparted shows me the disk correctly; it just contains one large NTFS partition I want to shrink.
I have it had it running for one hour now.
Question: will this work? There is lots of disk access but the timestamp and size of the underlying file disk.img remain unchanged.

I want to increase the size of my Linux partition (yellow and highlighted in image), which is situated in an extended partition, along with my biggest partition.
When I try to select the options from any partitioning software (EASUS, Paragon, Gparted) the option to resize is not available (or can't enlarge).
For example in the Paragon Hard Disk Manager, I can't add free space before the partition, even if I first shrink the "G:" partition, then try to enlarge the one with Linux.
Do you know what's happening here? Why am I not allowed to resize the partition?

I'm trying to resize a partition from a command line using the instructions on this page:
[URL]
The line below is the one I can't get to work right.
Quote:
Now, using fdisk, we must resize hda1 to 6000M, and create a new partition. Command: "fdisk /dev/had".In our case, the fdisk commands are "p d n p 1 1 +6000M t 7 a 1 n p 2 enter enter w", resulting in this "fdisk -l /dev/had" output :
I've made this work before but I cheated by using Acronis to create the partitions. I really want to get it to work from command line.

l my root (/) partition has 11G free space and my /home is only left with 5g around and /usr has around 8g in my fedora 13 .So is there any possibility to "resize" the root partition and add it to home partition bcoz i see the opposite in the threads(resize home to add space to root).My home has nothin more than a movie which is 700MB and i've installed some new application yesterday. But it shows half of the space is almost used!!!
/dev/sda7 12G 925M 11G 9% /
tmpfs 497M 2.6M 495M 1% /dev/shm
/dev/sda9 12G 5.0G 6.0G 46% /home
/dev/sda8 12G 4.1G 7.3G 36% /usr

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.

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.

I didn't know a resize operation on a 750 GB disk was going to take 40+ hours, and I was biting my nails the whole time, until the power went out when "only" 8 hours where left.I can still mount the partition, and many of the files are still there, but some files show as '? ? ? ? ? filename.ext' with ls -l.If I try to go inside such a directory: Input/output error.

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.

Recently my laptop broke down and wont start up. I'm currently trying to recover my files to my mac with an IDE to USB cable. It recognized my windows partition fine and I was able to get all my files off of that, but the majority of my stuff is on the ext4 partition that I have on it. Does anyone know how to access the ubuntu partition of this hard drive from my mac?

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.

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"

I have around 30gb of free space in my partition table immediately before the Linux partition. I want to resize my linux partition to take up this space.
I tried booting with live cd, sucessfully umounted the hard drive but found I could not resize the partition. On clicking the 'edit size' button, partition manager recognised the free space before the partition but when i reduced this, the 'ok' button was greyed out. (it was not greyed out for the windows partition so I could, in theory, increase the windows partition to take up the free space but this is not what i wanted to do).
I am pretty sure that I had managed to unmount the drive correctly as the padlock symbol had dissapeared (I took the attached screenshot, which does show the lock symbol, after rebooting into my normal system).
Anyone got any ideas as to why it wont allow this? There is no reason why i can resize the partition to take up the free space BEFORE it is there?

I have a 1T Western Digital external hard drive. As usual my first thing to do was use cfdisk to wipe out the existing partitions and create new ones. When I plug it in, it mounts a "partition" which does not show up in fdisk, and it mounts it as if it were a CD (ie. /dev/srx instead of /dev/sdx) labeled WD Smart Media or something like that.
