Fedora :: Difference Between Unmount And Safely Remove
Mar 25, 2010
I have an external HDD which I use under Fedora. After finishing with my work, I unmount all the mounted partitions of the external HDD & then proceed to switch it off. The HDD partitions are unmounted but they are still visible(but not mounted) under computer. The HDD still seems to spin. But when I click on "Safely Remove Drive" they disappear from Computer & also the HDD stops spinning albeit the switch on HDD being powered on. So what should I use "Unmount" or "Safely Remove". What is the difference between the two?
I have two devices connected to my usb ports one is a mouse and the other is a fan for a laptop. I looked on the left side of dolphin and opened sysinfo:/ and i cant see them anywhere to unmount them, when i want to remove them? how do i safely remove hardware
To remove pendrive when I click the 'safely remove' tab instead of getting removed from the desktop it reappears again. This problem is there in fedora 14
Anyone else seeing this? I do 'safely remove' to remove USB flash drive. disappears. Five seconds (or less) later, it reappears. The second time I do 'safely remove', it stays gone.
I am having Fedora 11 installed on my laptop. I installed Ubuntu 9.04 a few days back but I don't seem to like it. I had installed grub loader of Ubuntu 9.04.
Until a recent software update, I encountered no problems when 'Safely Removing' my external hard drive.
After the following update:
Aug 23 14:36:03 Installed: kernel-devel-2.6.35.14-95.fc14.x86_64 Aug 23 14:36:13 Installed: kernel-2.6.35.14-95.fc14.x86_64
The system freezes when I try to safely remove the drive. What I see is the blue screen with the Fedora logo, the caps lock key lights up and the system is totally frozen. Following is the information on my external drive gleamed from the messages log file when the device was mounted:
Aug 26 07:53:03 localhost kernel: [ 496.855476] usb 1-1.2: new high speed USB device using ehci_hcd and address 7 Aug 26 07:53:04 localhost kernel: [ 496.942025] usb 1-1.2: New USB device found, idVendor=1058, idProduct=0704 Aug 26 07:53:04 localhost kernel: [ 496.942031] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
I managed to successfully upgrade FC11 to FC13. While doing the post upgrade steps, I made a HUGE mistake. After identifying the unsupported packages, I used "yum remove package1 package2" command to remove the obsoleted ones without realizing the yum was also removing many FC13 packages! Here are the cmd sequence used:
I simply typed Yes and left unattended for a few minutes after yum prompted there were # of packages to be removed as I blindly believed it would do the job. After returning to the computer, I found many installed icons were disappearing, the wireless suddenly turned off etc. I killed the yum process right away but it was too late.
-Is there anything I could do to undo the yum remove process?
This has been bothering me for years now...when I go to remove a thumb drive from my computer, I have two options when I right click the device eject and safely remove. What on earth is the difference supposed to be?
I'm running Fedora 15 GNOME3 on a Compaq Presario C700 laptop.
I have an external Transcend HDD. I have three partitions on it.
When I insert it, it's automatically detected and the partitions mounted and works perfectly well but when I "Safely Remove" the disk, Fedora freezes and hangs. The mouse is immobilized and none of the keyboard actions work. I can't even enter the Virtual Terminal. The music playing in the background loops a short 1 second buffer or so.
However, if I eject all the partitions by clicking on the eject button in Nautilus and then "Safely Remove Drive", it does not crash.
I have 350GB external Western Digital USB hard Drive.When I try to remove it from the system by executing Safely Remove Drive menu the fedora 15 system gets stuck.The processor starts giving a hum sound and it goes on even if it is left for half an hour in the stuck state.The Mouse is not working and everything is halted.
Is there a good/simple way to do this?OK - Under certain other OSs, the 'safely remove' option on usb devices will...1/ On usb pen drive with a power/activity led, switch it off (trivial nicety, but reassuring).2/ On usb HDDs, spin down the disk - seems more important.I don't know if it really is but 'pulling the plug' on a spinning HD makes me nervous!I have tried a number of linux distros recently and only ubuntu 10.04 with gnome seems to do the same. Most others (including openSUSE 11.2, kde 4.3.5 - which I have) only seem to unmount
I am currently running the xen (64 bit) kernel, but want to move to the non xen kernel(64 bit) while retaining my carefully crafted system. I tried this once before by unticking the "virtualisation" and it removed the xen kernel, leaving me with nothing to boot from.
After some recent upgrade of my Debian Testing i386, on ThinkPad T400s, I am receiving panic message upon Safely Remove Drive.When I insert external HDD, it is automatically detected and the partitions mounted and works perfectly well. But when I "Safely Remove" the disk, Debian freezes and hangs. Nothing works (mouse or keyboard), and even X crashes and I get frozen terminal.I never experienced anything similar
I have a usb wireless adaptor that I sometimes need to remove from the computer, but often it locks up my system upon removal, even after typing "ifconfig rausb0 down" Is there a Linux equivalent to the windows "safely remove hardware" applet for usb devices?
I wanted to know command to triggered "Safely Remove Drive".So I could implement it on Hardy 8.04 http://ubuntuforums.org/showthread.p...88#post8674988
Can I safely remove 1 distro without screwing up the other? I have Linuxmint as secondary and ubuntu as the last.I want to replace ubuntu.If I just delete the partitions/format and install my other os which is OpenSuse 10.03 will this work.will opensuse see linuxmint and make grub understand?
I bought a disk to a friend that used it in a raid array, using the entire disk for the raid usage. To put that disk on service, i used dd-rescue to copy my old disk entirely, and managed to grow and setup a the partition table without losing any data. My last step was to create a RAID between my entire old disk, with a single partition and a partition of the same size on my new disk. I ran into some problems, but i manage to somehow fix it imperfectly, but now this setup is working properly. The problems (and imperfection) came from an issue it did not suspected : at some point, the original RAID superblock of the new disk, living in /dev/sda, resisted to dd-rescue, and so it is scanned by mdadm that tries, obviously unsuccessfully, to use it.
Partition layout :
Code:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
[code]....
this setup is working properly besides this raid5 declared on sda, so that is shows up here and there. Since it is using the same device name that my other, proper raid setup, i don't know how to deactivate it since mdadm uses the /dev/mdx name to identify arrays.
After a fresh install of 10.04, there are many applications which I will never use. I am just scared to remove them, because if I try, I end up losing my desktop interface. And which ones can I safely remove?
Is it possible to safely remove Document Viewer from Ubuntu system? When I try to uninstall it using the Software Center it says that the Ubuntu Desktop system will go with it. Is there another, safer way?
The bad news comes that active support for Mint6 is set to end Apr. 30. The worse news is I don't know what to do about it. Complicating this is that I have about 5 drive partitions and duplicate Mint6 operating systems because of password problems and just partitioning the drive and rebooting the OS instead of trying to fix the issue. I hear good things about Mint8, but my 80 Gig drive is getting pretty thin on partitions. I know there must be a way to safely remove the partitions and duplicate operating systems. I just don't know how to do it.
sda1 - WinRE - Something Windows uses 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".
Is there a command line alternative to clicking on "Safely Remove Drive" in nautilus?
When I click on "Safely Remove Drive" in nautilus, the USB HDD attached (WD Elements) vanishes from the nautilus "places" list, the drive spins down, and the light on the drive dims to indicate that it is powered down.
I have tried the "umount" command as well as the "eject" command from the terminal, but they both only seem to unmount the drive, as it is still shown in the nautilus "places" list and the light on the drive stays bright.
I've got a couple external hard drives on my Ubuntu Server 10.04.2 box. One of them, a Seagate FreeAgent 2TB, powers down after it's unplugged from the USB port. The other one, a Seagate GoFlex Desk 3TB, stays spinning and doesn't power down if it's unplugged from the USB port. The 2TB drive is USB 2.0, while the 3TB drive is USB 3.0, but I don't know if that makes a difference.
I'm looking for a way to "safely remove" it so that the device powers down and the platters stop spinning before I unplug it. I did find a thread on the debian forums that was looking for the same thing, but I'm not quite sure how to tell which usb port that drive is hooked up to (since it's using an add-on USB 3.0 card). Not even sure what command would be used either.
