Ubuntu :: External Hard Drive Connected But Not Shown Mounted
Aug 12, 2010
Hard drive is connected to my Inspiron 1525 via USB, plugged in and I'm not seeing the new drive mounted. Restart doesn't fix things and manually trying to mount /dev/sdb1 doesn't work either. The drive I got is preformatted as NTFS and I've been using a logical partition formatted as NTFS as a sort of share drive between my Windows partition and Ubuntu partition, so I know I have NTFS set up properly. This is the hard drive I'm working with for reference.

I administer a remote server via SSH that runs CentOS 5.5. I have been unsuccessful in all my attempts to write to two different external USB hard drives with a single ext3 partition when logged in as root.
When attempting to create a "test" directory I get one of two messages:
Quote:
Both drives *appear* to have filesystem issues. When I run an fsck on either drive, I get:
Quote:
Keep in mind this is a newly-formatted, empty drive.
Not putting stock in the odds that I've had two hard drives (different sizes and brands) with the exact same hardware problem, I'm going to assume this is a software issue, although maybe it isn't. Hence, my post in "Linux - General". I've heard talk elsewhere of controller (chipset) issues coming into play. Is this valid?
Okay, here's the information you'll need to make a diagnosis....
Here's the output of a "df -h" command:
Quote:
Here's the contents of my /etc/fstab:
Quote:
Here's the output of "cat /etc/mtab":
Quote:
Here's the output of a mount command:
Quote:
Here's the output of fdisk on the device in question:
Quote:
The number of cylinders for this disk is set to 48641.
There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)
Command (m for help):
I've got someone with access to the box if necessary. But it might take days to implement solutions since this isn't his full-time job. Remote solutions are, therefore, preferable.

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

I tried both disk in my laptop (Windows XP) & it works.

I have a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.

1) Environment:
Ubuntu 10.04
2) Phenomenon:
External hard drives won't be automatically mounted after upgrading some packages...
I have a "not good" habit: I'd love to upgrade whatever suggested by Ubuntu upgrading center every morning.
However, after upgrading some packages for today, my computer won't be able to automatically mount external harddrives, including file systems ext4 and ntfs.
My question is:
1) How can I check what packages have been upgraded just within today?
2) How to make my Ubuntu be able to automatically mount external hard drives whenever I plug in a harddrive as before?

See "10.4 synaptic package manager error" thread, for more details. Basically, I want to find a way to save my data. To do that, I need to figure out what exactly went wrong. Any of u who really wanna help, see that thread and the 1 mentioned in that thread, in order to extract a reason for all this madness from carefully examining every erroneous step.

The /mnt/ext is mounted to an ext2 filesystem, an external hard drive. For some reason I can't run scripts from there. Please see the session below.
luntain@plato /mnt/ext $ echo "echo success" > k.sh
luntain@plato /mnt/ext $ chmod 777 k.sh
luntain@plato /mnt/ext $ ./k.sh

I have an HP Pavilion that was/still is running Vista. I recently decided to dual-boot to Ubuntu from an external hard drive. Both systems will boot up fine its just that for some reason it won't boot to the internal drive (with vista) unless the external is connected. I just put the HD in another laptop only to have the same problem.

[openSUSE 11.1, kernel 2.6.27.45-0.1-Default, Gnome 2.26.3] I have a problem where I have an external USB drive which mounts at boot, with /home aboard it along with several data-only partitions, and if I try to add another USB drive *after* boot, the system changes the device IDs previously given to the original drive. The already running sdb now becomes sdc. If a user or processes are attached to /home when this occurs they are left in the twilight zone and stuff starts crashing. An added weirdness is the newly added drive isn't stealing the sdb ID, the added drive becomes sdd instead, and nothing at all is left at the sdb ID.
Note:
- System boots from sda, a non-USB drive with the system as well as /swap onboard, that should be uninvolved with the problem.
- Among the 4 partitions of the boot-mounted USB drive there are 2 lux-encrypted partitions (ext3). One is /home (originally encrypted under 10.3 and added back after machine upgraded to 11.1) and another being a data directory (later encrypted under 11.1).
- The problem _may_ occur only when the additional added drive is also lux-encrypted, but this may or may not be always true as I have limited other USB stuff to test with, most of it is also lux-encrypted.

What happens when you wipe a hard drive which has a partition that is mounted? I was using ubuntu 9.10 live CD but I had one partition on a hard drive mounted. Then, I started to wipe the entire hard drive with random characters using dd. Only later I realized that I hadn't unmounted that partition. what could have happened? Could the Live CD have been damaged?

I have properly ejected a USB memory stick and removed it from the port, but it remains in my 'Places', on the side pane of Nautilus. The /media directory is empty.

When I plug in my external USB Hard drive which is formatted as a single NTFS partition, it is recognized and mounted automatically, a nautilus window pops open. Unfortunately it is not writable. The reason is: the partition is mounted "ntfs" (which lacks write support) instead of "ntfs-3g". This is the output of mount after plugging in the drive:
$ mount | grep sdc1
/dev/sdc1 on /media/4EBC5FB82435B0EE type ntfs (rw,nosuid,nodev,uhelper=devkit,uid=1000,gid=1000,dmask=0077)
I want this partition to be writable by just plugging it in.
The partition should not have any errors because a) I fsck'ed it windows and b) mounting it manually works:
$ sudo mount -t ntfs-3g /dev/sdc1 /media/disk_/
$ mount | grep sdc1
/dev/sdc1 on /media/disk_ type fuseblk (rw,allow_other,blksize=4096)
$ devkit-disks --mount-fstype ntfs-3g --mount /dev/sdc1
Mounted /org/freedesktop/DeviceKit/Disks/devices/sdc1 at /media/4EBC5FB82435B0EE
$ mount | grep sdc1
/dev/sdc1 on /media/4EBC5FB82435B0EE type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
$ gnome-mount -nbtd /dev/sdc1
$ mount | grep sdc1
/dev/sdc1 on /media/disk type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
How can I get ntfs drives to be mounted as writable by default, preferrably without having to modify fstab?

I'm running Ubuntu 9.10 64-bit.
For some reason, the second hard drive (sdb1) is not automatically mounted:
rick@rab-1:/mnt$ sudo fdisk -l

Before I installed Ubuntu, I installed the RAID software to handle 4 500 GB hard drives - so there are supposed to be two mirrored drives. I'm not an expert in using RAID. I'm assuming it is correctly configured. I only "see" two drives. sda has Ubuntu etc. How can I get sdb1 mounted? I've tried using the palimpsest program but I'm afraid I screw it up. Do I need to re-format sdb1?

My version of linux has a bunch of GUI icons on the left hand side of the screen (vertical). Most are links to programs.You click the GUI icon and the program opens. When I mount my internal hard drive it adds a GUI icon for the drive. The problem is when I click on this new GUI icon it automatically loads K3b and gives an error message instead of giving me a list of what is on my drive. I deleted the program K3b and tried un-mounting then re-mounting the drive. I then tried the new GUI icon for the drive and now it automatically opens Dragon Player.

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.

I got a sort of usb connected device(not an external enclosure) so i can connect a sata hard drive into a machine that only has ide connections but the drive is not mounting. I am not very good at mounting slave hard drives anyway ,,,,never been able to get one happening without help. I am wanting to read this drive as i killed another desktop machine(i think the mb) and i need the data off the hard drive. The drive is shown in a directory and in the media directory. Can't think of what else sorry as i am so tired from testing everything out of the machine that i killed.....

I have an old computer that I want to turn in to a backup server. I was planning on using a 1 TB drive connected by a SATA card since the motherboard only has PATA. However when looking everything I've found makes it sound like I need to install the card for it to work. I want to know if I can install Debian to the hard drive through the SATA card or not?
