i do 10.4. as recently as two weeks ago, i could use my mp3 player as a usb drive. now the player is still auto mounted, but i can't copy/paste to it or cut files from it. i do see it in rhythmbox, but when i right click and choose "eject", the drive unmounts and the mount process starts over. when i check permissions, i see that i am "read only".
View 4 RepliesI've got a bare bones Ubuntu 10.04 set up (xorg, openbox, usbmount). My (vfat32) stick drive mounts, and I can see what is in the one directory on the drive, but I can't write to the drive unless I use sudo. I tried the obvious step of attempting to change permissions on the drive..

View 9 Replies View RelatedI use davfs2 to mount a Webdav drive at startup. It mounts correctly and I have read access to all files my account gives me access to. One big problem though: I can't create of modify any file. I know it is not a user account problem because everything works well when I mount the drive in Windows 7 using WebDrive.
Here's the entry in /etc/fstab to automatically mount the drive:
Code:
http://someserver.local/docs /home/my_user/km_docs davfs user,rw,auto 0 0
The Webdav is hosted on a local SAP Portal server (if anyone is familiar with this).
I also tried to use Cadaver. It connects and reads perfectly. But when I try to create a file, I get a "409 Conflict" error, even the file has never existed on the server before.
When I installed Ubuntu, I was asked to enter a user name and password. I chose one that would be a sort of "administrator alias" and gave it a strong password. This is my "su" name and password. That works fine for most things, such as installing software, etc.. Every so often, however, something comes up that can only be accessed by "root" and that is not me, even logged in with my "administrator alias" and password. This happened when I inserted a USB flash drive and tried to copy some files to it that I wished to transfer from my desktop my laptop. The only way I could do this was to format the flash drive. and then add my files to it.
This morning I inserted the flash drive and tried to add another file to it, using "copy" and "paste". Again I got "permission denied" and the owner of the flash drive, seen as "usb0", was again "root", and I could not change its permissions, because I am not "root". It also says the device is not listed in etc/fstab. I have read the Ubuntu paper on mounting USB drives, but I'm not sure that applies here. The drive seems to be mounted, but with the wrong owner.
This problem has also occurred with some software when I tried installing it. I usually give up and don't install it. This flash drive problem, however, is driving me crazy. I need to transfer those files. Is there something I'm missing? Despite installing and upgrading Ubuntu on 2 machines, I'm still pretty much a newbie, and if it involves using the terminal, I need step-by-step instructions,

I've tried everything I can find to make it usable again in Windows but I ran out of options. I quickly found about the Gnome Partition Editor, but when I try to start it, it gets an icon in the taskbar that says "Starting GParted" and then it closes. Is some other way I can format my flash drive or do I need to find out why gparted isn't running?

If I have Ubuntu installed on a USB drive and run it on a PC (not installing to the PC...just running the Live version), is anything at all written to the host PC's hard drive? I don't want the host PC's hard drive to be written to at all for security purposes. I'd be using Firefox, LibreOffice, and other apps that come with the Live USB version.

I have have Centos 5.3 which does not save files to USB drives. after copying over file to an empty drive the files are shown on the drive and can be opened and edited but when the drive is removed and reinserted the drive is empty again even though I have told the it to remove the device. I suspect that the file cache is not being flushed correctly. Is there a way of checking this and forcing it to flush the file cache if this is the problem?
View 4 Replies View RelatedI have a computer with no floppy drive (x64 ubuntu lucid installed) I have a program (wine windows xp) that will only save data and export data from/to a floppy drive. I found information on setting up an emulated floppy drive. i.e.
sudo dd bs=512 count=2880 if=/dev/zero of=imagefile.img
sudo mkfs.msdos imagefile.img
sudo mount imagefile.img /media/floppy -o loop
I modified the winecfg to include under the drive section A: /media/floppy. Problem is I cannot write to the drive as a normal user. I have tried everything I know but only root can read write to the drive. Is there someway to set up this emulated floppy to allow me as a user to write and read contents.
I'm trying to back up my hard drive to a 2 TB WD external so that I can do a clean install of 10.10, however I'm getting tremendously slow write speeds. It hovers around 1.5 MB/s and steadily slows from there. It tells me it will take 150+ hours to transfer 400 GB of data.
I have a AMD quad core processor and 8 gigs of ddr3 ram... USB 2.0... I feel this should go much faster.
I'm only somewhat new to linux but I still don't have a real grasp of it's deep innards and I had a fairly outlandish idea that I'm wondering whether is possible/plausible or not.I want to run a game server on CentOS that has a very high dependency on fast writes-to-disk. Disk writes are pretty much the single bottleneck in this server.First I looked at allowing a high queue of writes to pile up before it flushes them to the disk, but I read that this causes fsync, which is still used commonly, to take a very long time.
I've been thinking about the possibility of running the server on a RAM disk, but I still want changes to be saved to non-volatile storage. Not all at once, but have it actively write the changes to disk. The hope is that this would smooth out the peaks and valleys of write activity and improve overall performance, but I have not seen this idea discussed anywhere.
So my question is, is there any plausible way to continuously copy writes to a RAM disk to a physical drive without slowing down the speed of the writes to the RAM drive below the speed of said RAM? Or is there a better way to obtain this sort of performance, short of investing in expensive equipment?
I am having a problem writing to an NTFS pendrive. I have created the NTFS pen drive in the following way:
Code:
fdisk /dev/sda
created the label with 'o', then written the table with 'w'
I've then gone into fdisk again :
Code:
fdisk /dev/sda
started the partition creation with 'n', and chosen 1 partition '1', then written that with 'w'
I then used mkntfs to format:
Code:
mkntfs /dev/sda1
The blkid command gives me this output:
/dev/sda1: UUID="58CEA9511D6BCEFA" TYPE="ntfs"
I can mount the pendrive (as root) with:
Code:
mount -t ntfs /dev/sda1 /mnt/pendrive
and the mount command output:
/dev/sda1 on /mnt/pendrive type ntfs (rw)
I have changed the permissions on /mnt/pendrive (while mounted) to 777, owner/group=root. However, when I try to copy something to the drive I get this error:
cp: cannot create regular file `/mnt/pendrive/file.txt': Permission denied
I installed AlienBob's KDE 4.6.2 a few days ago to give it a shot.
I'm really satisfied with it and wish to keep it, but there's one thing bugging me : I can't write to my NTFS USB drives.
To be precise, I can write as much as I want to existing files, but I can't add nor delete files nor directories.
Worse, root isn't allowed either, even in runlevel 1 when mounted by hand (mount -t ntfs /dev/sde1 /mnt/foo).
Did I miss something to configure among the dependencies of KDE 4.6 ?

so after searching and reading, and searching some more, im stuck. i cant seem to get a mounted thumb drive to give write access. first thing to know is that, im using a seagate dockstar with a primary thumb drive[sda1] booting debian and samba.
i guess you could say im still in the testing phase, just trying to make sure files can be shared, mounted and accessed by users. the problem is stated as the title. i have successfully shared a folder in sda1 with rw access, but i cant do the same for the second drive[sdb1].
for sda1 with rw access, here are the smb.conf settings:
Code:
[shared]
path = share
available = yes
valid users = mark

I currently discovered a problem when using the floppy drive /dev/fd0: I can't use it. I can mount /dev/fd0 as normal, can create/write a file, but it is not written to the floppy disk. Instead of that the current program (eg vim) hangs (or is "uninterruptable") until I remove the floppy disk from the drive. Because of the removal I get several errors in /var/log/messages. What I'm doing:
== snip ==
mount /dev/fd0 /mnt
echo "TEST" > /mnt/test
sync [--> HANG until I remove the floppy disk]
[sync "completes"/terminates, insert floppy disk]
umount /mnt
== snap ==
(In this example I used echo instead of vim, because it behaves the same in this situation) The errors I get are as follows:

When I mount an external usb drive on linux (CentOs4), the permissions are by default set to read-only. Since there are multiple users on the computer who need to use the external drive, I want everybody to have rw permission for the entire drive. I also want them to be able to mount the drive if the computer has accidentially been shut down. They can use sudo mount to mount the drive, but this will only give them read permission, and I obviously don't want to allow sudo chmod.
Is there a default setting that I can change so that every new external usb disk automatically gets rw permissions?

I'm testing OpenSUSE 11.3 on a server and I'd like to disable the write cache on all of my drives. In Ubuntu Server I was able to accomplish this with hdparm by adding the appropriate settings to /etc/hdparm.conf
As far as I can find the only thing that OpenSUSE offers is /etc/sysconfig/ide which allows you to force particular DMA modes. I could just put the hdparm commands in /etc/init.d/boot.local but I'd prefer to do it the right way if there is a right way to do this in OpenSUSE.
I have a very very insane problem with my ssd sata harddisk. I did fill the harddisk, and Thunderbird complained about "no space left on device". But even if I delete some files from the harddisk, df will still say 0 blocks free. But it will decrease the number of used blocks. So it looks like it is freeing the blocks and deleting the files, but it don't put the blocks back to the free pool.
But here is where things get insane: If I log in with my normal user, I get a "No free space" when I try to write to the harddisk. But If i log in as root I can write to the file system, despite the fact that df is saying 0 blocks free. I did try to run fsck -f but it just run its test and then say that anything is fine. But it run for less then 10 seconds, is this expected on a 40GB ssd partition?.
