Hardware :: External HDD Won't Stay Mounted ?
May 14, 2011
My external hard drive randomly unmounts in the middle of file transfers.
The system is Debian Wheezy with sda as single-partition ext4. I have an INEO I-NA212-J USB 2.0 enclosure with 2xHDD single-partition ext2 which are recognized as sdb & sdc.
When files are transferred from the external to sda, the system will unmount the external drive at random times. When that happens, "fdisk -l" no longer reports sdb & sdc, but does show the drives as sdd & sde and they can be mounted. I have to reboot the machine to have it see the drives as sdb & sdc again.
When transferring from sda to the external, the unmounting is less frequent but I get file corruption. For example, a large directory seemed to transfer successfully, but the result showed as a single executable file and the displayed file properties were just long strings of numbers. Deleting the file did not reclaim the space.
There seems to be no pattern to the failure. I have checked for file size, number of files, system uptime, transfer time, etc. I have so far not seen it happen while there is no activity. The problem is the same whether there are 1 or 2 drives in the enclosure. However, I have used USB thumb drives and microdrives (both vfat) without problems.
For mounting, I have tried both "mount" and "pmount", and for file management both Xfe and Midnight Commander.

I've got an external HDD from Iomega that I've been using for over a year and lately it's been doing this thing where it suddenly changes from /dev/sdg to /dev/sdh while the partition on it is still mounted, seemingly at random. I'm often (not always) able to look at the contents of the partition, but it gives me I/O errors followed by a list of files and directories.
I am using slackware64 13.0 running kernel 2.6.29.6. Below I've provided the relevant lines from dmesg (edited out irrelevant lines to keep post under max character limit.) I'm beginning to suspect NFS has something to do with this, but I can't even begin to imagine how.
When this happens I'm able to umount -l the partition and remount it using the new /dev/sdh1 but eventually the same thing just happens and the whole drive switches back to /dev/sdg. This problem persists between reboots. It's also happened with an ext3 filesystem, in fact I switched to ext2 because it kept telling me "Aborting journal" and I was afraid I would get a corrupted journal and perhaps a destroyed file system.
About 8 months ago I was doing some work at my brother's place and while down on the floor fiddling with cables I yanked this whole drive off the desk and it smashed into the floor (while spinning probably, I'm pretty sure this model is disk based.) I've been expecting to see some strange behavior since that happened, but it took a while and I can be certain this is related to that incident, although I'm rather convinced it is.
Code:
sd 5:0:0:0: [sdg] 976773168 512-byte hardware sectors: (500 GB/465 GiB)
sd 5:0:0:0: [sdg] Write Protect is off
sd 5:0:0:0: [sdg] Mode Sense: 34 00 00 00
sd 5:0:0:0: [sdg] Assuming drive cache: write through

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

I use dual booting, vista ubuntu 9.10. I have just bought a new 1T external harddisk i have used it on windows to backup some files. Now I want to backup some documents in ubuntu, but the harddisk is not visible, I can't see it, ok I think the term in Linux is that it is not mounted. Is there something else one should do ?
Disk /dev/sda: 640.1 GB, 640135028736 bytes

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.

[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.

Is there anyway to get a 2 terabyte NTFS partition mounted in Suse Linux? Would be better to just mount if possible so I could use the storage for both my Linux and windows pcs.

i have an external harddrive which i encrypted scince opensuse 10.2 with luks. Now i installed opensuse 11.2 its impossible to me to mount this drive correctly.
the harddrive was recocnized in my former opensuse 11.0 correctly as luks encrypted and during installation yast installed the kernel module and encrypted the harddrive so that i regulay could mount it on boot by giving the password for that harddrive. Scince opensuse 11.2 however yast thinks this is an dmcrypted partitoon and tries to unlock the harddrive using dmcrypt which of course fails.
does somebody know how i can encrypt and mount the externeal drive automaticly?
i have made a backup of /etc before i made a new installation of opensuse 11.2. is the possible to use the old fstab entries for that after installing luks?

I have a headless 8.04 server with 2 USB drives attached. I'm trying to move everything off the 1.5TB drive onto a few 300GB drives (so I can then use LVM on the 1.5TB drive and move everything back onto LVs.)I check the drives using 'fdisk -l'. They show up as sdc1 and sdd1. I mount them and start a cp operation.When I run fdisk again, the drives are no longer sdc1 and sdd1. Now they are sde1 and sdf1 (and of course, they are no longer mounted.
What could be causing this and how do I fix it?I need to fix this ASAP because the 1.5 TB drive seems to be going bad. Every few seconds I hear a big "click" as though the head arms are smacking against a stop. (This is the 2nd brand new 1.5TB drive that has started doing this!)

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'm running a cron job every night to dump a MySQL database to an external hard drive. It works, however when I check on it the following morning the external is no longer mounted and the XFS log file is corrupted. If I run
Code:
xfs_repair -L /dev/sdf1
It works, but then I get these issues:
Code:
XFS: Filesystem sdf1 has duplicate UUID - can't mount
I can reset the UUID, but it's difficult to have to do this every day.

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?

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?

I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

I need to read information from SUN hard disks which are about a decade old. My CentOS 5.6 mount command comes from util-linux 2.13-pre7."mount -t ufs -o ufstype=sun /dev/sdb2 /New" reports "mount: unknown filesystem type 'ufs'", though its man page describes such settings.How could I read an external UltraSCSI hard disk (yes: high pitch noise and only 9 GB capacity) on a current CentOS? Is that possible at all?

I frequently turn my monitor off (e.g. during downloads). Usually,
Code:
works great for this purpose, but on my new Thinkpad W520 with Fedora 15 the monitor won't stay off but come back after a few seconds. This is rather annoying. Does anybody have an idea how I can make it stay turned off? Oh yeah: Pad is deactivated, only trackpoint is active.

I've set-up my main panel along the bottom of the screen. However when I reboot/restart the little F!@#$% is back up top again. So I figure fine right click properties/set to bottom. But no. It jumps right back to the top. like I didn't select bottom at all. Also its happening on both my laptop and netbook.

I have a project with a small device which is running xubuntu. Running DHCP all works fine, but we are sending this out to a client who gave us some specific IP settings.There is nothing GUI wise, which is nothing tragic, so I updated the interfaces file with the static info as well as the /etc/resolv.conf file and rebooted. The static info worked but had no DNS, and all that was in that file was;#SETUP by Network Manager (or something close as I am not at the office).
You can run via cli NetworkManager but does nothing. I installed I think it was called KNetworkManager which is a GUI to the app, but when started it shows the eth0 device as in use so I am assuming something else is managing.So basically how can I get the DNS settings to stay either cli or gui..

I just installed FC12 (2.6.31.5-127.fc12.x86_64) alongside Windows7 on a brand new box, and the DVD drive is driving me nuts. In FC, I can't get the DVD drawer to stay open. When I press the eject button, r slides out, but then slides right back in again immediately. When I start the SystemTools->DiskUtility (Palimpsest), the Eject function is grayed out.The drive itself seems to work just fine, I used it for the FC install from LiveCD. In Windows, the drawer works properly.The only device info I can see for the drive is DH16AAL, I don't know if that's a model no. and I don't know the manuf. Says SCSI, but it's got a SATA cable. The rest of the box is:

I am very new to the wonderful world of Linux and from what I've read about and my limited experience (approx. 3 hrs) I like it; but I'm having one problem that I need to get fixed: I'm dual booting currently with W7 (boo) only because I can't get my internet to stay connected(?) for extended periods of time using F15.
When I first installed F15, everything went smoothly, it asked me for my PW for the wireless internet and it said that it was connected. After I loaded Firefox for the first time, thinking to myself "Awesome, it set itself up completely and is running perfectly) I was let down. On my laptop I have Quickbuttons. Touch sensitive buttons above my F-keys (incase you didn't know what I was referring to. When I connect to the internet, with my wireless card on, I can successfully load 1 internet page. Halfway though the page load, the internet light/button starts to flash repeatedly on/off rapidly. Internet connectivity seems to have stopped at this point as I can not load another internet page or use the chat window any more. If I disconnect from my internet and reconnect, everything works fine for 1 more internet page then back to flashing and no more connectivity.
If I restart using the Windows OS, everything works fine and my desktop is working normally as well, so it must be something with F15. What do I need to do in order to get the internet card to work continuously? What am I missing? Please remember, I'm very new to this and all the troubleshooting web pages that I've found thus far are talking WAY above my head.

So lately I've been playing searchandrescue and I think it's great, like a simpler version of Simcopter. But for some reason the key will stay on until I close the game, and occasionally after I close it. For example, if I hit m to check my map while the engine is revving up, it will stay on, and when I hit a button that requires typing, it will just be a bunch of m's. Or sometimes if I hit an arrow key it will stay on, then I'll exit the game and move up to the menu and the key will still be going, but when I hit the key again after the game is closed it will stop. Any ideas on this one? Once I figure out the command to start searchandrescue in the terminal I'll post the output when the bug occurs.

I'm having this problem with a older ibm thinkcentre with some:00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04)
video controller in it.
The problem is the monitor connected has to stay on all the time, but something keeps shutting down the video card then the machine has been idle for some time, and the monitor goes "No video signal" until someone touches the mouse or keyboard.
The system is the newst updated 9.10, and ive set "Put monitor to sleep = never" in the power management settings. Ive also disabled the screen saver.
Now, i dont think its Xorg that shut the video card down, i believe its the framebuffer (or kernel console or whatever its called). If i jump to the console with ctrl-alt + F1, log in and turn off Xorg with lets say sudo service gdm stop, the video card still turns off after like 15-20 minutes.
Other things ive tried:
completely disabling framebuffer in the grub configuration (with vga=normal and nofb and even combining both, this however doesn't really disable the high resolution framebuffer at all. Its still on now matter how much i try to disable it..hmm (and the grub settings is used by grub as I'm able to set nosplash witch is effective))
and the last thing I've tried was setterm -powersave off, no luck there.
Before thinking it may be the console doing the video poweroff, I tried disabling DPMS in Xorg config, (and disabling it with xset) this dosent help, although i'm able to turn on the video signal again from a ssh session with xset -dpms -display :0.0 or xset dpms force on -display :0.0. However after some idletime the video signal shutsdown again.

I am running a dual-boot with Ubuntu 10.10 and Windows 7 and I can't stay connected to the internet with Ubuntu, but Windows does. My router is a D-Link GamerLounge DGL-4500. I have wireless internet access for about 10 seconds but then it drops. Access to the router doesn't go away though. Other computers can connect to it just fine, and my computer (Toshiba Satellite A505) has connected to every other one I've tried on. I can still log in to it and change settings and all that, but I can't access the internet through it. I also can't ping the router.
