[SOLVED] cannot mount vfat usb

When I plug in my usb device an error is shown:
Error mounting /dev/sdc1 at /run/media/toni/BE40-9797: Command-line `mount -t "vfat" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=100,shortname=mixed,dmask=0077,utf8=1,showexec,flush" "/dev/sdc1" "/run/media/toni/BE40-9797"' exited with non-zero exit status 32: mount: unknown filesystem type 'vfat'
How can I solve this?

So, why did the reboot work ? (asked rhetorically)
Unlike some other famous operating systems,it is not likely that you machine had reached some unstable state requiring a restart to put it into a known state.
In your case, you probably updated the kernel. When this happens, the kernel modules on disk for the running kernel are replaced by those for the new kernel. After you did the upgrade, you plugged in your USB device. The kernel looked for its modules, but they were gone -- replaced by those for the new kernel. After rebooting, you are now running the kernel that matches the installed modules.

Cannot mount external USB drive

During a recent update I remember pacman asking about replacing some package with another package to handle disk mounting. I think the added package was "gnome-volume-manager" or "gnome-disk-utility" (or both). I didn't see any postings describing problems with doing this, so went ahead and allowed the change. Now it's a few days later and I find I cannot mount an external USB hard drive anymore. It has an entry in fstab, and although I have tried mutiple edits of the device to associate the drive with, nothing works.
The disk used to associate with /dev/sdb1. Now this device no longer exists. Here is what has happened to my /dev/sd* entries:
brw-rw---- 1 root disk 8, 0 2009-10-27 11:08 /dev/sda
brw-rw---- 1 root disk 8, 3 2009-10-27 11:08 /dev/sda3
brw-rw---- 1 root disk 8, 1 2009-10-27 11:08 /dev/sda1
brw-rw---- 1 root disk 8, 2 2009-10-27 11:08 /dev/sda2
brw-rw---- 1 root disk 8, 4 2009-10-27 11:08 /dev/sda4
brw-rw---- 1 root storage 8, 16 2009-11-04 13:00 /dev/sdb
Trying to force association with "/dev/sdb" "/dev/sda5" (or some other number not in use) or "sdb1" (or 2,3,4, whatever) just yields "special device ... does not exist".
Does anybody know how to deal with this?
Does anybody know what package(s) I replaced when the update in question took place? I think I'd like to reverse whatever happened.
And on another note, I think another gnome-based package also recently replaced a package relating to printing. Yesterday I discovered I have printing problems too:
At first there were no printers found. Although cups is supposed to start according to rc.conf, cupsd was not running. I started it manually and then all the printers showed up again, though I cannot print duplex (again, worked fine before). What is going on with these gnome packages?!? Anyone know which package(s) I need to remove (and then what to put back) to make printing work like it used to also?
thanks much.

oddly, fdisk -l shows nothing, even for disks which are mounted (eg. /dev/sda4). when I insert a standard USB thumb drive, the following show up properly:
brw-rw---- 1 root storage 8, 32 2009-11-05 10:50 /dev/sdc
brw-rw---- 1 root storage 8, 33 2009-11-05 10:50 /dev/sdc1
and I am able to mount and use the drive as usual.
The external drive I've been struggling with has xfs for filesystem type. After using the thumb drive, /dev/sdb showed up spontaneously, but no /dev/sdb1. attempting to mount gives:
mount: /dev/sdb is not a valid block device
or
mount: special device /dev/sdb1 does not exist
depending on which device is specified in fstab.
I am thinking that either a) my ability to mount xfs filesystems has somehow been hosed, or b) there is something wrong with drive, which must have spontaneously failed very recently (it is less than 1 yr old, but this happens from time to time).
If the drive is okay, any ideas about how mounting xfs filesystems could have been broken by recent upgrades?
btw, the fstab entry (which worked fine until a couple days ago) is: /dev/sdb1 /mnt/external_1 xfs rw,noauto,user,exec 0 0

[SOLVED] Truecrypt mounts vfat volume as read only

Hey there...
After the recent upgrade to linux 3.0.6-2 truecrypt mounts VFAT volumes as read-only. The file that I usually mount is in a USB which is formated as NTFS (I can copy and delete files from the USB). I think is a problem with the vfat filesystem but I'm not sure.
Any help?

I apologize because of this post... The problem was in the file (something was wrong with the container)... so the solution was to do a new volume and copy all the files to the new file.
Best,

I have a Gen 2 connected right now, it most definitely uses UMS. I have a Gen 4 at home that also uses UMS. I've got to assume your Gen 3 would as well.
Does it go to the "USB Drive Mode" screen when you plug it in?
Edit: Do remember having an issue one time where it would not go into USB mode. Rebooting the Kindle fixed it. On my Gen 2, you would go to the Home screen, then hit menu and settings, hit menu again and there's an option for "Restart".

[SOLVED]Cannot mount partitions with PCMANFM --no longer an issue

Hi,
I have searched and searched and pulling my hair out on this issue. I am using PCMANFM .9.10 on an LXDE install using the Arch x86 iso. My HD contains several linux partitions and a FAT32 partition.
I am not able to mount these partitions in PCMANFM. I am able to mount my usb flash drive
When trying to mount a partition in PCMANFM I get a "not authorized to perform operation" error message.
Today, June 11 I partially rewrote this due to the lack of response I am getting on this problem.
1. did a reinstall of Arch & LXDE today. I've done two or three installs. dbus is in daemons in /etc/rc.conf
2. initially the partition icons did not show up
3. then, I installed gvfs and added 55-my-conf.pkla in /etc/polkit-1/localauthority/50-local.d/
4. With that the partition icons show up in PCMANFM
5. But I still get the "not authorized to perform operation" message
The 55-my-conf.pkla has this content:

I changed <action id="org.freedesktop.udisks.filesystem-mount-system-internal">
mount a system-internal disk at <allow_active> from "auth_admin_keep" to "yes".
Still didn't work!
Either this is a bug or I have a permission problem somewhere.
Can you please advise how to do this or point me to a recent tutorial to be able to auto mount other partitions not using /etc/fstab? Some of the older posts refer to hal or other package that have been deprecated.
Thanks
Edit: latest. It seems that I must mount the desired partition from the terminal. example: $sudo mount /dev/sda5 /mnt
then can edit it from PCMANFM by going to / and then /mnt. Apparently I do not have to manually unmount.

Wow even I accidentally disabled swap somehow and I tried everything, but it would not work ( http://bbs.archlinux.org/viewtopic.php?id=52252 ) . But, changing the line in fstab worked like a charm. Thanks!
(Maybe this is some sort of a bug? )

[SOLVED] Cannot mount usb (as normal user)

Hello
I'm facing this problem for the first time, but can't tell if it came after an update or an unexpected reboot (light went out).
I'm using latest kde (4.9.2?), and the latest kernel,
Linux gantz 3.6.6-1-ARCH #1 SMP PREEMPT Mon Nov 5 11:57:22 CET 2012 x86_64 GNU/Linux
When I plug any usb device, kde ask me what to do. When trying to mount it, either from the kde "mount" plasmoid or from dolphin, I get a "Not authorized" error. Mounting via cli with sudo works fine.
After doing some research, I found that I need to be in the storage group in order to be able to mount, so I checked, and I was already on the storage group. Next.
More research sent me to lots of pages talking abour .xinitrc, wich doesn't exists (on my home, at least). Also tons of pages where talking about somethin like "exec ck-launch-session dbus-launch session-manager" (I login via kdm), but the ck-launch-session is not found on my computer either.
So i'm stucked right now, and don't know how to proceed, any clues? Thanks

that's not a fix, it's a crappy workaround. You are not supposed to touch these files, they will be overwritten on an upgrade. My guess is that you are simply not using systemd and therefore you are not in an active logind session. You have to boot with systemd, as mentioned in the news. Everything should then just work out of the box.

Cannot mount external USB drive with FDisk_partition_scheme

Due to some recent mac issues in my lab, we updated one of the computers to Maverick 10.9.4 from Snow Leopard 10.6.8 yesterday. Anyhow, this seems to have erased the ability of the mac to read or mount several identical USB drives with the NTFS format (WD My Passport Ultra 500GB USB3.0). It could do it yesterday when it was OSX 10.6.8, but not today (OSX 10.9.4). The drives still work fine on other OSX 10.6.8, Windows 8.1 and Ubuntu 14.04 computers (this is appears to be a problem with the Maverick 10.9.4 operating system itself, rather than the flash drives which work flawlessly with every other computer I've tried). I want to remove data from the computer to create backups on the USB drives (no, I don't want to create an online backup or buy a new set of USB drives).
diskutil can see the drives, but cannot verify or repair them as they lack a GUID (GPT) partition scheme. I'm assuming this is the root of the problem. Manually mounting the drives does not work. Installing the ntfs-3g driver also did not work (I was using this to write to the NTFS drives until we upgraded OS's). Installing the WD Passport drivers for OSX also did not work. How do I get the mac to mount these drives?
I could reformat one USB drive and then copy to the others, but this would be extremely inconvenient and take days of copying files back and forth (and would prefer to fix the mac rather than go through this with every NTFS drive I own). If I did this, the FAT32 hard drive format would not be suitable, as format is unable to handle the extremely large sequencing datasets I need to transfer. I'm not super familiar with hard drive formats, but in the event we cannot get Maverick to actually work could someone possibly suggest a format able to handle large file sizes (the largest file I need to move is ~60GB) and be compatible with Windows 8.1 / OSX 10.9.4 / Ubuntu 14.04 as well?
Another workaround I thought of would be just to install an Ubuntu partition on the mac and get the files off through the Linux install. Which is also inconvenient, but would probably be faster than trying to reformat the drives and copy everything over onto them again given the amount of data I want to transfer.
Unrelated, but is there any way to view files and folders in the OSX root directory besides through Terminal? It seems like this functionality was also removed when we "upgraded" from Snow Leopard. (At this point, if it were up to me I would wipe all of the macs we own and replace them with Ubuntu... even the most minor of tasks always require some sort of workaround with them... at my wits end here ).

Yeah this definitely appears to be a problem specifically with this mac. It's been having all sorts of weird problems lately, and we figured that upgrading to Maverick might fix them (but instead we got new problems).
To give an update on this, I ended up reformatting one of the drives to HFS+ and disabled journaling. It now recognizes the drive again, and I'm pulling the files off that way. I looked at exFAT, but it looks like HFS+ has much better Linux support (Windows is read-only but that's only a minor annoyance, as the algorithms to process the data only run on UNIX machines anyways). It's a shame I couldn't keep using NTFS (had to copy over literally EVERYTHING again...) but whatever. Again, no solution for the issue (where this mac can't read NTFS drives).
@rkaufmann87 - To give a bit more explanation, we recently had to disable online backups because apparently the sheer amount of data causes Time Machine to freeze the computer and fail every time it has a scheduled backup (original issue we thought that upgrading to Maverick would solve... didn't work). The hard drive has been having a lot of issues when it begins to reach max capacity as well. So I am pulling off all of my files to external hard drives and deleting the local copy before we attempt to back up online again. And the data would probably take me a year and a lot of money to recreate (for the curious, it's high throughput sequencing data). I'm choosing not to take any chances as a result.

[SOLVED] Cannot mount ntfs drive

Every time I try to mount my Windows 7 hdd, I receive an error:
fuse: mount failed: Device or resource busy
The commands I used to try to mount all resulted in the same error:
sudo mount /dev/sdb1 /mnt/ntfs
sudo mount -t ntfs-3g /dev/sdb1 /mnt/ntfs
sudo mount /dev/disk/by-uuid/C0940E83940E7BE2 /mnt/ntfs
Switching to root also did not remedy the error. Putting the entry in fstab does not mount it at boot, giving the same error.
fdisk -l reveals the following:

EDIT: Solution:
As it turns out, a couple years ago, I had a mirrored RAID. Even when got rid of the RAID, got a new drive, reformatted and installed Arch, my secondary, NTFS drive would not mount.
Here is exactly what fixed it:
Issuing the command `cat /proc/mdstat` shows all RAID arrays. Mine showed the following:
Personalities :
md127 : inactive sdb[1](S)
488386496 blocks
`sudo mdadm --stop /dev/md127` stopped the array.
`sudo mdadm --remove /dev/md127` removed the array.
new output of `cat /proc/mdstat`
Personalities :
unused devices: <none>
`sudo mount /dev/sdb1 /mnt/1` worked.

[SOLVED]Cannot move files from mounted usb drive

When I try to move a file off of my usb drive I get the following error:
mv: cannot remove ‘homework-1.txt’: Permission denied
The usb drive is mounted to a folder that I created as a normal user in my home directory. However, when I call ls -l on my home directory it says that the directory I'm using as a mount point is owned by root:
$ ls -l | grep mnt/
drwxr-xr-x 10 root root 4096 Dec 31 1969 mnt
When I unmount the flash drive, the ownership of the mount point changes back to me:
$ ls -l | grep mnt/
drwxr-xr-x 2 hugo hugo 4096 Feb 4 16:12 mnt
When I move the file I want as a super user it works but I don't get to retain ownership of the file anymore.
How can I make it so that when I mount the usb drive I have access to it as a normal user?

You've also given the rule an irrelevant name (locale? wat?), and then point to an incredibly outdated resource (last updated nearly 6 years ago!!!) about udev rules. udev(7) is far more relevant and up to date. It doesn't mention outdated commands which no longer exist (udev$foo were all merged into udevadm).

Cannot mount any firewire/USB external drive after software update 10.5.4

After the last software update on 10.5.4 it did not complete the installation, and get stuck at the last step of running installation script for hours. So I have to restart the computer, and it restarted fine. Then I use Disk Utility to check my hard disk, and discovered some file system inconsistency error, so I repaired it (in target disk mode by another Mac). After it is repaired, the file system passed with no error.
But ever since then, I cannot mount any external firewire drive or USB drive. I cannot use Time Machine to backup my disk. I think my firewire and USB ports are fine because I can restart my iMac in target mode and connect to my MacBook via firewire, so the hardwire ports are functional, except that it seems 10.5.4 cannot detect or mount any external drive after the failed software update.
Does anyone encounter similar problem? How can I fix it? I have my disk backed up by TimeMachine but I cannot restore it if it won't let me mount my TimeMachine disk. Is there any other way other than completely reinstall 10.5 from scratch?

first, you should try reinstalling 10.5.4. download the [combo update|http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1054com boupdate.html] and run it. If that doesn't fix the issue, you can use full system restore from TM to go back to a time before the troubles started. to do that boot from the leopard install dvd, once past the language screen go to the Utilities menu at the top and choose "restore from backup".

Cannot mount USB disk in SIngle-user mode (solaris 10)

Hi all ,
I need some help please :
I can read/write to my USB disks when i'm in muti-user mode but when to I swith to single-user mode ( init S ), I cannot mount it.
in Single-user mode , i started volume management daemon :
#/etc/init.d/volgmt start
#volcheck
but i'm still not able to mount it.
I tried to mount manually:
#mount /dev/dsk/c2t0d0p0 /testpoint , i have this error: < mount : not a UFS magic number ( 0x0) , dev/dsk/c2t0d0p0 is not of this fstype.
My system recognizes the USB device though in single-user mode:
This is an output of #iostat -En
c2t0d0 Soft Errors: 1 Hard Errors: 0 Transport Errors: 0
Vendor: BUFFALO Product: ClipDrive Revision: 2.00 Serial No:
Size:0.07GB <65339392 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0

Hi ,
thanks for your advice. My problem is resolved.
The USB drive was actually a FAT filesystem.
so I did # mount -F pcfs /dev/dsk/c2t0d0p0:c /testpoint and everything went fine
I can read/write to my USB disks when i'm in
muti-user mode but when to I swith to single-user
mode ( init S ), I cannot mount it.
in Single-user mode , i started volume management
daemon :
/etc/init.d/volgmt start
#volcheck
but i'm still not able to mount it.It probably requires other items to be started
first.
I tried to mount manually:
#mount /dev/dsk/c2t0d0p0 /testpoint , i have
this
error: < mount : not a UFS magic number ( 0x0) ,
dev/dsk/c2t0d0p0 is not of this fstype.
Looks like it's assuming UFS. If this is a pcfs
filesystem, give it the type on the mount line.
# mount -F pcfs /dev/dsk/c2t0d0p0 /testpointYeah, this was the right command, I had to specify option < -F pcfs >.
but I read somethere on this forum i had to specify :c as the drive for FAT at the end of c2t0d0p0 , so the full command was:
# mount -F pcfs /dev/dsk/c2t0d0p0:c /testpoint

Domain User cannot mount USB or shutdown

Hello,
after a few weeks when I installed Samba and joined a Domain I realized that when I put in an USB stick my file manager tells me that this operation is not allowed. So I have to mount the USB stick with sudo. Did I make something wrong in the PAM configuration? My domain user is in the local group of storage and power ...
It would be great if some one can give me some direction where to look for the problem.
Regards
Debellator

Thanks for your fast response.
When there is a kernel update I do a restart.
I do not use a login manager.
#!/bin/sh
# ~/.xinitrc
# Executed by startx (run your window manager from here)
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f
fi
setxkbmap de
# exec gnome-session
# exec startkde
# exec startxfce4
# ...or the Window Manager of your choice
exec ck-launch-session startlxde

B-tree error, cannot mount Lion partition, but can mount bootcamp partition. Unable to reformat because it won't mount. How do I reformat?

Hi everyone:
So earlier today I was taking a screen shot with (command+shift+4) and right when I took it, the spinning wheelcame up on the screen. It was there for a long time, so I decided to turn off my macbook by holding down thepower button. When I turned it on, it stayed at the grey apple logo with the loading circle underneath.
I turned it off again, and this time I started it into the Recovery HD. I ran a disk verify and it said my disk was corrupt and needed to be repaired. I tried to repair it and it said it could not be repaired. Next, I tried to erase the hard drive and it still didn't work because it cannot mount the hard drive.
The thing that baffles me is that I have 2 partitions on my hard drive, one for mac, the other for windows bootcamp and the windows hard drive is able to be mounted. I tried to completely delete the entire hard drive, but it won't let me. What are the next steps I should take into solving this problem? Any/All help is appreciated. Thanks

Sounds like the drive may be faulty or have suffered a problem. Bummer mate, but it happens.
Disk Utility won't let you do a complete erase? Probably not what you want to do anyway as you'd lose your bootcamp partition.
I would recommend you replace the drive and re-install OS X. Once they get faulty like this you're into a greatly increased risk window. You'll need to have a bootable DVD / USB stick of Lion or a RecoveryHD USB created by the Lion Recovery Assistant.
If the MBP is under warranty or you have Applecare you could get the drive replaced under warranty.
To retrieve your files and Apps etc you can restore from a backup, or if you don't have one then you could get a sata enclosure for the old drive and attach it as an external drive then attempt to copy the content from it once you've re-installed. Time Machine backups will make this much easier for you though.
For bootcamp, you're going to need a 3rd party program such as Winclone (www.twocanoes.com) to allow you to take an image of the bootcamp partition and restore it to the new bootcamp partition on the new drive.
I can heartily recommend the Seagate Momentus XT 750GB hybrid drive (ST750LX003) if you're going for a replacement. You won't believe the difference in performance it provides.
Good luck!

W541: Cannot boot from USB created with Windows 8 create recovery drive

Hello, I have just bought a W541, and want to install the supplied Windows 8 on an m.2 SSD.I created the recovery drive on a USB following the instructions in the User Manual, but the recover image procedure under Advanced Options cannot find the USB.During the re-image step, it fails to find a drive with a valid image.I've confirmed using the command window available under the Advanced Options that the USB is mounted Searching these forums, I found the following, which describes a similar problem for a T540:https://forums.lenovo.com/t5/ThinkPad-W-Series-Laptops/Lenovo-W540-won-t-boot-from-USB-flash-drive-ThinkPad/m-p/1500902#M39097 This implies that the USB should first be formatted with FAT32 before use, which cannot work, since FAT32 only has a maximum 4 GB partition, whereas when copied to the USB, the Windows 8 recovery drive occupies nearly 10 GB. Is it possible to specify the boot order from insde the BIOS? I could only find an entry under Security about UEFI boot enabling, nothing about the boot order. Can anyone help?Paul

Hello Z, thanks for the reply. I tried another USB drive, and created a recovery drive, as before.This time it was able to detect the presence of the drive when I tapped on the Enter key when starting up, followed by the F12 key. However, there are still problems when I clicked through the options:Choose the languageChoose your keyboard layoutTroubleshootAdvanced optionsSystem Image Recovery At this point I am offered the option Windows 8.1.When I select this, it indicates it is scanning for system disks, and then displays the the pop-up window "Re-image your computer": "Windows cannot find a system image on this computer" Why does this happen if it detected that there was a Windows 8.1 installation on the USB? I've spent a whole day now on this. Luckily, if I can't solve it, the machine is new and I can send it back to Lenovo, and ask to have it re-imaged with the downgrade option to Windows 7.
