Hardware :: Cannot Unmount From Hard-drive To Create Partitions
Feb 27, 2009
I am using a live-cd version of linux and want to install it to my hard-drive but when i try to unmount it and go into qtparted, it says it is still busy so i cant perform changes. This is my result when i type "mount"
Code:
aufs on / type aufs (rw)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
/proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
[code]....

I was trying to create a partition on my hard drive on Linux using the GParted program. I noticed my hard drive had a key next to its name but could not find information regarding it online. I proceeded to unmount the drive and made 2 partitions. However, it game me an error saying it couldnt make the partitions. I turned my computer off thinking i would get back to trying tomorrow. Today i turn on my laptop and see the usual hp screen. But after that it goes to a black screen with a blinking underscore looking thing. It goes nowhere from there. It usually goes to a black screen after the hp logo, that says GRUB loading.

I have an external hard drive which connects to a usb port. until recently i could unmount it by right clicking on the desktop icon and selecting unmount. now when i try that it tells me that i can't because the device is not in fstab and i am not the root. i checked mtab and it had this line '/dev/sdb1 /media/usb0 msdos rw,noexec,nodev,nosuid 0 0' i changed that to '/dev/sdb1 /media/usb0 msdos user,rw,noexec,nodev,nosuid 0 0' thinking that would fix it, but it didn't. i unmounted using 'sudo umount /media/usb0' and restarted my computer and now the line in mtab reads '/dev/sdb1 /media/usb0 vfat rw,noexec,nodev,sync,noatime,nodiratime 0 0' and i still can't unmount without using the sudo umount command. i also tried adding '/dev/sdb1 /media/usb0 msdos user,rw,noexec,nodev,nosuid 0 0' to fstab and that didn't help

I am having this problem. I use an external usb hard drive with my pc running on ubuntu 11.04, If I keep the hard drive idle for a few minutes, ubuntu unmounts it. I suspect there are some options for this, so I looked into the Power Management section, but found nothing that can solve the problem.

I have Seagate Freeagent Go 500GB external hard drive that I use for backup. I wanted to resize the partition so I used GParted to shrink the 500GB NTFS partition to 400GB. The other 100 I wanted to encrypt and use for some other more important files. For some reason, the shrink failed and I disconnected the hard drive and reconnected it. I didn't see the icon appear on the desktop. I went into the Disk Utility to discover that GParted's shrink error deleted all of the partitions on my hard drive. So I created a new 400GB NTFS partition and put back all of my files. The other 100 is unallocated currently.
It will normally mount automatically and show up on the desktop but the hard drive won't mount without me going into the Disk Utility and mounting it through there. I can't even mount it from the Terminal with root privileges. It gives me this:
Quote:
sudo mount /media/My Data
mount: can't find /media/My Data in /etc/fstab or /etc/mtab
Now, I can unmount with root privileges and I can unmount it from the Disk Utility. I can browse and edit the files within. But I can't unmount it from within Nautilus or on the desktop (the Safely Remove Drive option is not there).
The new 400GB partition also isn't detected by GParted. It just shows the whole drive as unallocated.

I am trying to mount an external USB hard drive. I'm using Debian Lenny 5. I tried to right-click on the hard drive and then select the mount command inside the gnome desktop environment but it gives me an error. Is there an easy way to mount and unmount this hard drive? The hard drive itself is formatted from the factory in NTFS. I'm going to leave it in this file format is a need to use it with Windows machines as well.

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"

So I recently got a WD MyPassport external hdd with 500gb capacity. I formatted it to NTFS so that it would be more efficient transferring data between my Ubuntu and Win7 dual boot. But now I want know if it is possible for me to create a 100gb FAT32 partition on the external without destroying the data on it.

Is there any way to Merge hard drive partitions? I didn't really know what I was doing during install and wound up leaving myself with over 100GB of unallocated hard drive space. if I create a new partition out of this, could I possibly merge it with another? and if I do, should I merge it with root or home? I am using 10.10, by the way.

I'm working with an older PC that belongs to my parents. They've been using Ubuntu 8.04 with no problems, and with 10.4s release, I planned to upgrade them to the newest version. The system's specs are as follows:
1.5ghz Athlon XP CPU
1.5gb RAM (PC 2700)
20gb hdd (IDE)
I have tried both the Ubuntu 9.10 (two different discs) and a 10.4 install CD and both give me the same issue. The installation proceeds along swimmingly until partitioning comes up. The partition table simply shows no hard drives. I have heard of this issue occurring with SATA drives and motherboard settings, but what could make it happen to an old IDE drive? Any odd-ball motherboard settings or anything that might need to be changed? GParted and the Live disc (along with the currently installed version of Ubuntu) recognize drives and can navigate them. What gives?

I just bought a new 2 TB hard disk to replace my old 175 gig one. I currently am dual-booting Lucid Lynx and Windows 7, and rather than go through the process of reinstalling both, then reinstalling all my programs, settings, and everything, I was wondering if there's a way I can just copy the partitions on my 175 GB disk to the new one, grow them to fill up the rest of the free space on the new 2 TB disk, and then plug that HD into the primary master plug on my motherboard... will that work?

I've recently bought the "new" Macbook from Apple. It obviously came with OSX preinstalled. And I'm obviously not satisfied with the way it works, I also need a FAT32 partition so I can share my files between all three OS's. Tricky business. And I thought later on I might try and create me a nice LFS system to learn about Linux and show of to my mates. But doesn't a single hard drive only support up to 4 partitions? So off I went and got Ubuntu running besides Mac. It wasnt recognized by neither the default boot-loader nor rEFIt straight away. I had to hold alt to come up with the special BIOS or something every time I needed to use Ubuntu (always).
I got up to a point where I could run Ubuntu with wireless, sound and pretty much everything working. Until the kernel updates were installed. Somehow I (or maybe it) managed to screw up and booting had become impossible, for it would crash halfway through with kernel errors and other undefined weirdnesses. Meanwhile I had tried installing Windows 7 on a different partition. Which I found to be catastrophic also. I was forced to put up with OSX, which in my opinion is fine at what it does but it doesn't do very much for me. After a couple of tries I had to give up on fiddling with Ubuntu for I needed Windows 7 to run software for school. So my current partition layout looks like this......

Ubuntu 10.10 I would like to access the partitions of my hard drive from the Places menu. They show up there, but when I click them, the menu just closes. I can access them by navigating Places>Computer>"Drive_Name" but it would be more convenient. I was able to access them before, but something has apparently changed..

So this is a two part question. My laptop came preinstalled with windows 7, I wanted ubuntu but needed windows to update my zune so I have both operating systems on my laptop. I only used windows for my zune, that was its sole purpose, now my zune is broken and I no longer need windows at all.
First, I downloaded about 20gb of music off of my zune and onto my windows partition, is there any way to transfer files like these from one partition to another? I don't know if that makes sense.
Second, can I unpartition my hard drive so it is purely ubuntu ** without losing all my ubuntu files and stuff **? If that wasn't clear, I want my laptop to just have ubuntu, I want the 40-some gb that I dedicated to windows back for ubuntu, and I don't want to lose all my files, settings, etc. that I already have on my ubuntu partition. Can this be done?

I installed Ubuntu 9.04 on my latop. I have an older 80 gig HP laptop with Windows XP. Currently, i have XP as the NTFS drive and it takes up about 72 gigs of space, the swap drive for ubuntu is about 256 MB and the ext-3 drive is 2.5 gigs. However, i have no more hard drive space to run or instal any programs on Ubuntu. So what i need to do is decrease the NTFS drive as i still have over 30 gigs of free space on my laptop and increase the ext3 drive to about 10 or 15 gigs and increase the swap drive?

I'm in the process of building a new Fedora machine. I use the machine for a VMWare server, the file server for the house as well as a Linux desktop for work.My current machine has a single 1.5GB hard drive. The new machine will have a mirrored RAID drive(2TB). I'm also contemplating using a smaller 250GB drive for the OS installation. I would then divide up the 2TB drive into /home and /var/lib/vmware partitions where the bulk of the data would reside.The goal is to be able to unmount the /home and /var/lib/vmware partitions when I need to upgrade the OS version with the data intact and remount them once the new install is complete.
The goal is to keep the family network file shares and my Virtual machines intact while reinstalling the new Fedora OS from scratch. In theory it should work. I just want to mak an (in)sanity check to ensure it will work in practice.

I'm trying to install Fedora 3 Core on an old hard drive I had lying around. The problem I'm having is that when I go to manually repartition the hard drive with Disk Druid I get this error: Could not allocate requested partitions: Partitioninf Failed: Could not allocate partitions as primary partitions. I can't view the contents of the hard drive to delete stuff.

I am attempting to install 10.10 from the iso because I have no working cdrom. I uncompressed the .iso to a ext3 partitions and put the correct entries in the menu.lst file. It starts ok. The problem occurs when I attempt to install to the hard drive. At a point I get the error,
Failed to unmount partitions The installer needs to commit changes to the partition tables, but cannot do so because partitions on the following mount points could not be unmounted./cdrom I have a choice of continue or go back. If I continue the install hangs. If I go back I cannot continue. How do I fix this problem?

I've performed a clean install of Linux on my system, and would like to create a snapshot of my whole disk so that I can go back to a fresh state immediately.
I used to use DriveImage XML and it was a FANTASTIC program, but unfortunately the boot CD containing it can only be created by having Windows installed. So it might be time to explore a new program that is equally simple and effective as that one.
I'd like your recommendations of imaging programs that are free, and that work off a boot CD/DVD (because the live backup thing generally takes much longer for imaging an entire disk).
One thing I liked about DriveImage XML was that it stored the backup in a fairly readable format, so if one day DriveImage XML were no longer available you wouldn't lose your backed up data. Any such programs?
Also, would these programs work for a drive that contains an encrypted root partition (i.e. enabling the encryption checkbox in the CentOS installation)?

The motherboard currently installed on my PC has a RAID Utility (Ctrl+I) at the startup that allow creating RAID1. But I already have a system installed with CentOS 5.4. In order to protect my data, I need RAID1. Can I add another Hard Drive now and have the data mirrored and synced onto both hard drives as if it was in RAID1 right from the beginning?

When I try to install Kubuntu 10.04 from the live CD (ran the installer from the Live Desktop) I get this error:
I then get sent back to the partitioner after clicking continue. Nothing but the installer/live desktop is using the cdrom. How do I install it? I have also tried running the installer without the live desktop, and it still throws the same error at me.

I'm overall realitively new to Ubuntu 11.0.4 and I had some questions regarding this operating system. I just wanted to inform everyone, that I'm attempting to make a transition, from a life time Windows user and a current Windows 7 Ultimate user, to being a Ubuntu user.
I am becoming fedup with Windows 7, because i dislike how much system resources, it requires to run, and in addition I'm skeptical about Windows security. I had a lot of bad experiences with the Windows updates as well, so I was kind of alienated, as one can imagine. What I did like about Windows 7, is how easy it was, to configure the user group policies. I was wondering if you were able to do that in Ubuntu latest release.
I also was wondering, if it were possible, to create a hard drive image, that I can just load up, if I ever needed to reformat, like I did in Windows 7.

My partition table is as follows:

sda2 - Windows7
sda3 - Data

I need to remove Ubuntu 10.04 and so I therefore need to remove sda5 and sda6, right? Upon deleting sda5 in Gparted it tells me to "unmount any logical partitions having a number higher than 5".
