I'm trying to get away from FAT and FAT32 for my memory sticks. Is ext2 really a suitable option for usb memory sticks?
I don't want to use ext4 because of journaling, as it's simply not required for usb sticks.
How good are USB memory sticks for running operating systems from, and the ones based in micro sd cards?
View 2 Replies View RelatedI have tried to write my files to 2 (2GB each) USB sticks and both turned into a Read-Only-File-System. Then I tried with my Memory Stick Duo and it also turned into that. So I give my last try with my SanDisk HC Memory Card (from photo camera) and resulted the same. I can copy the files of those portable storages into my HDD fine but not write into them or delete any files inside those portable storages.

I was told that it is because the file I deleted is still running and being used in memory. What is the memory portion called(such as user space) that the filesystem run in?
View 5 Replies View RelatedI am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?

I continuously receive the statement only root has the priviledge of writing etc. to the files on the USB stick. I have the same problem when I insert a card reader with an SD card. It is recognized but I do not have write priviledges.
When first a regular HDD boots up, the BIOS passes control over to the first 512 bytes of the disk, so long as the disk has the magic number (correct signature) at the end of this first sector. The BIOS doesn't 'care' what is in this first sector; it just passes control over to the code within it and hopefully boot-up is underway. Other boot instructions may commonly lay elsewhere on the disk, which is fine, since the boot sector code will point to them and the process goes on.
Now, what happens when you boot from a CD or a USB stick? Not quite the same thing happens, does it? What I need to know is, when booting from alternative media, what is the BIOS 'looking for' and whereabouts on these new media does it expect to find the boot code? I've looked at the directory structures of CDs and sticks and there doesn't seem to be any common factor in the files and directories there that I can identify, unlike when I examine a regular HDD and its partitions with a hex editor.
Well maybe I missed it,but is there a listing of usb Internet sticks that work with Ubuntu?
I see the page for network cards etc,how about a sticky for a Internet Key page ? Always up for saving time and money.
I now have an install of Ubuntu 10.10 on a USB drive and would like to clone the result onto another USB drive of the same size. Both USB drives are 4Gb. I've used Gparted Partitioning Editor and have copied from the master USB stick to another USB stick. Looking from within the editor they look the same in terms of configuration after the copying process e.g same filesystem boot flag set.
When I try to boot off the copied USB stick it comes up with a 'no operating system' message at boot. Is this the right tool to use to clone USB sticks or is there another option?
i have a dell laptop with an nvidia card (proprietary drivers from sbo) running 13.1. all of a sudden a random image from firefox would 'stick' on the display and it would be visible on other applications. for example, a yellow rectangle would appear wherever you go with firefox (on top of every page), on top of word documents (ms word is running under crossover), but it would not be visible on the kde desktop of dolphin.

Whenever I'm playing a video and bring another application to the foreground, the video window appears over the foreground application:
I'm running Natty Narwhal 64-bit. This didn't happen back in Maverick. The hardware is an Asus K42JR laptop. If there's any more detailed information that I can provide to help narrow this problem down, please let me know.
I've found a similar issue on the forums, but it seems a bit different. This guy also has foreground window problems, but in his case they occur with non-video applications and are not consistent (it only happens 10% of the time).
With me, it always occurs with only video playback. The choice of video application for playback does not appear to matter (I've tried Totem, VLC). Strangely, the problem doesn't occur when viewing flash videos from within Chrome.
How does one train a digital camera and USB stick to accept user access? Basically, this involves transferring photos from my camera to my machine, sorting and then moving favourites to the USB stick. Or moving selections that others have sent me to the USB stick. I am constantly changing ownership and permissions and it's driving me nuts. How can I send anything to a USB stick as a user?
View 10 Replies View RelatedI used to use Unison to synchronize files between various Unix/Linux computers. I've an USB stick onto which i put files I've to keep with me (when I work outside home). When I get back home I'll like to synchronize with my laptop running Fedora 11. If the file is on the usb stick no problem, it gets copied onto my home directory and everything is fine.
But if the file has to go onto the stick, Unison complains it can't set the file's permission (of course, on a Vfat file system) and refuse to copy it. Question : Do you know a way to avoid setting irrelevant permissions on a file with Unison or an other utility of this kind ?
Is there a way to test the integrity of USB sticks?
View 4 Replies View RelatedTo start with I know this is not a linux problem, it is purely hardware.After the computer has been on for a while and then restarted bios does not detect in POST the usb sticks that it is supposed to use to boot from. his is obviously a problem as bios can't use something it can't see to boot from.I'm wanting to know if anyone else has had a problem like this with my hardware? I suspect it is the Asus M4A78LT-M LE that has a usb detection problem, since I've tried plugging the same sticks in to another pc and they do not have the same issue on that pc.

I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.
I installed F13 on a few ACER desktops with 4 GB ram. Recently I tried to upgrade the RAM to 8 GB. But after I plugged in the extra two 2GB ram sticks inside, the system still feels 4 GB. I had double checked with ACER and confirmed that 8 GB is supported by the motherboard. Is there any shortcuts to let the system recognize all the 8GB ram rather than reinstall the whole system.
View 13 Replies View RelatedLooks like its some sort of PolicyKit issue. Documentation (and I suspect the system itself) all assume that I have only one user. But my computer is a two-seat, my girlfriend and I are logged in at the same time. Only I am able to mount and write to USB drives. I suspect its because my account is always logged in first.
Dolphin gives the following error: org.freedesktop.Hal.Device.PermissionDeniedByPolicy
blah blah org.freedesktop.hal.storage.mount-removable auth_admin_keep_always
So my guess is that this "auth_admin" for some reason only refers to my user. I opened up the "Global Configuration" application (something that typed up when I filtered for 'policy' in the application launcher), and added my user, my girlfriends user and the 'user' group as "System Administrators". I logged out and logged back in on her account and this did nothing.
We've just set up 3 Dell systems with 64 bit Red Hat Enterprise Workstation 5. As part of our system configuration we point the user authentication to our LDAP server, and automount people's home directories from our fileserver. At this point, our security people do some configuration and we get it back.
We are typically running KDE. On all three machines, when you plug a USB stick into the system, the familiar window pops up asking you what you want to do - open the contents in some program, open a file viewer, etc. and the stick shows up in /media When you stick a CD or DVD into the drive nothing happens - you don't get the options window and nothing appears in /media I'm trying to get an idea of how the automount process works, and where I may have stepped on it. We've got three more identical machines that haven't been installed yet, so my plan is to check the ability to automount CDs at various stages of our setup process.
When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.
I am trying to mount a file image, like this
mount -o loop /tmp/apps.img /media/apps
But I get the following:
mount: you must specify the filesystem type
I try ext3:
mount -o loop /tmp/apps.img /media/apps -t ext3
dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?
I have a Phenom II X4 955 box running 8G RAM. Now I'm planning building a Phenom II X6 box running 16G RAM. But the 4G module/stick is very expensive, not easy to find. However most mobo can take max 4 sticks. I can't find mobo board on market except server taking 8 sticks.
View 9 Replies View RelatedI'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.
