Trying to go through some old hard drives I'd saved from a Mac we tossed years ago. Using a Sabrent USB adapter (USB-DSC9) I connected it to the Debian box and it mounts as /media. Here's the weird thing: although I can read all the random stuff, the directory with all my actual documents shows up as "you do not have the permissions necessary to view the contents". When I try to fix this with chmod, it tells me that the drive is read-only. Grr.
How do I mount the drive so that it's not read-only?
I recently bought 320 GB Trancend external hard disk and working fine days back.Earlier i could copy from and to the hard disk with out any issue. I dont know what happened after that now i am not able to write any files in to the external hard disk. This is not NTFS formatted device. here is some of the out put from terminal.
Code: sundar@sundar-sundar:~$ fdisk -l Disk /dev/sda: 120.0 GB, 120034123776 bytes
I am making backups and I need to make a cron job that mounts a 2nd local hard drive.
It is not listed in my fstab file and I mount it manually in nautilus (having to type a password). It is designated as /dev/sdb1 and /media/repo when it is mounted. Can I get cron to mount it and then add the password or do I have to add it to fstab?
I set up a server using ubuntu 9.10, with two hard drives in a hardware Raid 1 setup and with two more drives for recurring backups. The problem is that the two drives for backup are set to read only and won't allow me to change the permissions even when logged in as root. I have tried putting "rw" into the "fstab" file with no luck, I have also tried running "gksudo nautilus" and "fsck -r /dev/sdc" but still have the same message that I don't have the necessary permissions to complete the task.
**I just tried erasing the data on the disk and creating a new partition, the disk utility allowed me to erase the data and create FAT32 partitions with the same permission problems but would not allow an EXT partition or NTFS partition (it would give and error message stating:"Error creating file system: helper exited with exit code 1: helper failed with:mke2fs 1.41.9 (22-Aug-2009)")**
***I fixed the problem by fixing a formating problem in fstab and reformatting the drives to ext4.(the fstab had a problem with the way that I broke up the lines when I input the info for the new drives, and I didn't realize it until I maximized the window in gedit.)***
I can not see my usb hard drive here is some information Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00021330 .....
I have a simple WD external USB hard drive, but when I plug it into my computer nothing happens. Not only is there nothing popping up, but I cannot access it through the file browser. The light on the hard drive turns on as usual.
I was in the process of backing up data from my hard drive to an external usb drive when the drive suddenly became read only. Does anyone know how I can make it read/write again? I am using Debian Lenny and the drive is ntfs formatted. I have another ntfs formatted usb drive that is not effected in this way.
I was busy making backups to my external hard drive just now, but Ubuntu crashed 10 mins into the backups. After rebooting the affected folders are now Read only, and I cannot add or remove anything. This is extremely annoying, I already threw away two USB flash disks because the same thing happened to me in the past. I don't want to throw away the external because it's far more expensive and packed with backups.
Symptoms: I can write or delete a file to the hard drive, in any folder, accept the folders that was being accessed when the computer crashed. I have tried to change permissions, but I get an error. I tried opening a terminal and sudo rm -r that folder, but I get a input/output error. I'm running Karmic. Backups were made by Back-in-time.
Below is results from attempt at formatting my hard drive. As you can see a driver is installed, but not working. Perhaps something is missing? Seems a bit odd that a "unable to read" comes back when disk data is reported. The drive just went through a low level format. BTW this is a fiber channel drive. Also on board are 5 scsi drives. Adaptec raid card. Not sure if that would have any relevance, but there you are.
I have a computer with Ubuntu 10.04, with few disk space. For downloading some torrents, I've connected a USB hardrive, ext4 formated. But this idea wasn't a solution, because the drive keeps getting read-only permission... Is there any way of prevent this to happen?
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:
Both drives *appear* to have filesystem issues. When I run an fsck on either drive, I get:
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:
Here's the contents of my /etc/fstab:
Here's the output of "cat /etc/mtab":
Here's the output of a mount command:
Here's the output of fdisk on the device in question:
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 am using Thunar and XFCE4. I started with the minimal install CD, so this is not exactly Xubuntu as I do not have Xubuntu-desktop package installed. I installed psydm to be able to easily edit and control mounting, fstab etc... Anyways, I can't figure out how to write to this disk. I have amended the Thunar icon to read "gksudo Thunar" as its command. It opens Thunar with whatever elevated rights that would come along with the command. I still can't write to the disk. If I change the permissions for the disk under the properties tab to be "read&write" for the user group, It asks me about something to be done retroactively to files. No matter whether I choose yes or no here, it still does not change the disk to a writable disk.
No love and no ideas. Can you help me write to this disk ? I run as a user called "user" so maybe I should not have made Thunar open as "gksudo" ?
so here's my issue and what I think is causing it right now. I have a 1TB external usb hard drive that has worked perfectly, but recently I set it up a mount point for it in fstab so that I could create a SMB share on the drive so I could stream videos and pictures to my TV through my Wii using WiiMC. This now works perfectly, but now the hard drive has been set into read-only mode. When I use sudo to try to chmod the drive or the folders on it, it does nothing. When I right-click on the drive and check the permissions tab, it says the owner is root and all the options are greyed out.
I've read through several posts on similar topics to this, but none of them have been very helpful as they suggest using command line tools that I don't know how to use, so I'm hoping someone here can give me concise, step by step instructions of what to type in, or what settings to change in fstab to solve my little problem so I can start copying stuff back onto my drive. I'm running Ubuntu 10.10 and the filesystem on the external drive is FAT32. Here's some more info you might need:
I am running Fedora 14 with kernel 18.104.22.168 x86_64 and I am having an issue with a Vfat partition that is shared with Windows 7 on a dual boot setup. this partition contains my mozilla profiles and it occasionally mounts as read only in Fedora. I wont be able to write to it and root doesnt seem to be able to write to it when this happens. I checked this by trying to redirect an output of ifconfig. My fstab entry looks like this.
Code: UUID=5830-75A8 /home/joe/share_storage vfat rw,umask=0000,uid=500,gid=joe 0 0 and ls -l
Code: drwxrwxrwx. 8 joe joe 4096 Dec 31 1969
These two (fstab and ls -l) always look the same whether the partition behaves as read only or not.
Since I've upgraded to Lucid RC1, when I insert my SD Card it mounts as read-only. The write-protected switched isn't on and my card isn't corrupt. I've tried chmod and chown to no avail.Does anyone know a work around so that I'm able to write to my SD Card?
I am trying ti set up a NFS server using the guide on [URL] However, the NFS mounts on the client side as a read-only file system, so I cannot modify nothing. Here is my /etc/export file on the server side:
Code: /home/acrocephalus/ 192.168.1.35 (rw,async,no_root_squash) and this is my /etc/fstab file relevant line on the client side Code: 192.168.1.33:/home/acrocephalus/ /home/acrocephalus/AcrocephalusServer/ nfs rsize=8192,wsize=8192,timeo=14,intr Then, I mount the system using the command Code: sudo mount /home/acrocephalus/AcrocephalusServer/ .
how to mount the NFS with full read-write permissions?
I am trying to add/delete files from my HTC Evo through ubuntu via enabling file sharing on the device. Ubuntu detects the drive, and mounts it up so that I can browse/read files off the device. However, I am not able to do any writing to the device because it is mounted as "read-only". The only wierd thing is that it worked last week, and I have not changed any settings on my system. Where should I start? Is the auto-mount for USB drives located in "/etc/fstab"? because here is the contents of that file, and I dont see anything for usb mounts:
Code: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name
I just did a clean install of Ubuntu 10.04 and Linux Mint 9 with an ext4 (sda3) data partition to be shared between both. My issue is when I go to that partition and mount it within Nautilus it mounts read only. I've searched around but I have not found the solution. I don't have a problem mounting it using fstab and mounting at boot. But, I know I have to be doing something wrong for it not to work correctly through Nautilus.
I partitioned the drive like this. Ubuntu sda1 primary partition ext4 25gb, Mint sda2 primary partition ext4 25gb and Data primary partition 56gb. I then installed Ubuntu 10.04 first, then Mint. Both Ubuntu and Mint mount that partition as read only.
I just got a new WD Studio External USB 2.0/FW800 hard disk drive, it is formatted to HFS+ with Journaling (hfsplus) and I use it for both an iMAC and a PC/Linux. The problem is that on my PC (Linux - Ubuntu 9.10) there is always some kind of read-only error whenever I try to edit, create, delete anything on it. I tried it on my iMAC and I'm able to read and write on it with no problem.
The mount command on Linux gives me: /dev/sdc3 on /media/My Passport type hfsplus (rw,nosuid,nodev,uhelper=devkit) Clearly indicating that it ("My Passport" on /dev/sdc3) is mounted as "rw" (read and write, not read-only). I tried connecting it via Firewire 800 and USB 2.0 and both give me the same results. I also tried fixing it in my iMAC using Disk Utility but it reports on problem and I clearly safely "Ejected" it before unplugging it from my iMAC.
I'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..
I recently got a computer donated to me for free from my Computer Science class, as the teacher couldn't figure out what the problem was that was preventing him from booting to the startup screen (all I could figure out was that the slot the memory card was in was bad, so I switched slots and got it working). The hard drive on the computer was wiped with a disk nuker called DBAN. Now I would like to install a Linux OS on the computer, but whatever disc or distro I try gives me similar "unable to read" errors. I would like to know if there's anything software-wise I need to do before attempting to replace any hardware. An example of the error I'm getting is as follows (using a mandriva livecd):
/etc/rc.d/rc.sysinit: line 1281: /var/log/dmesy: Read-only file system SQUASHFS error: sb_bread failed reading block 0xa6e58 SQUASHFS error: unable to read cache block [29b963ea:782] SQUASHFS error: unable to read directory block [29b963ea:782]
Anyone know what I need to do to get this fixed so that I can install a Linux distro?
I am running the latest suse release downloaded directly from their website. I ran the installation after buring the dvd and everything seemed to be working fine. after the installation i ran updates and used it for a little bit. When i shut it down that night and went to restart it I got an error that stated the OS wasnt there. I then went through the installation and everything and it retained the information from the installation before (web history etc.) but for some reason every time I reboot or shut it down the system is not able to read the startup information from the hard drive and will not come on without me re installing it.
i borrowed an external hard drive from my friend to back up a load of stuff on my windows partition before reinstalling it. I am doing this through ubuntu. I am trying to zip up folders like My Documents etc and chuck them on the external hard drive but it always comes up with errors to do with read/write permissions. In the permissions tab on the folder properties of the ext hard drive it says I am owner but i have no file access (only folder access is create and delete files). When i try to give myself read/write permission it just goes straight back to nothing when i look at it again.
I have one hard disk (call her HDA) that contains nothing but a single ext4 partition containing a backup of all my important data. I did a clean install of 10.10 on my primary hard disk (call her HDB) and from there proceeded to the 11.04 upgrade. In 10.10, I was able to read HDA just fine. However after the upgrade, I can no longer mount this drive.
When mounting from file browser: Code: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
The end of dmesg said the following: Code: dmesg | tail [49.853308] wlan0: associated [50.084874] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [52.859533] Intel AES-NI instructions are not detected.

For some reason my hard disk has a block count greater than the size of my device. I've done my background searching on this and tried a command line utility I've never heard of before: Code: # sudo e2fsck /dev/sda e2fsck 1.41.14 (22-Dec-2010) The filesystem size (according to the superblock) is 122096646 blocks The physical size of the device is 122096381 blocks Either the superblock or the partition table is likely to be corrupt! Abort<y>? yes
And this is as far as I've got. I'm really hesitant to start fiddling around and experimenting with possible fixes because the backup data on this drive holds a decade's worth of work for me and is extremely valuable (hence why I have a spare drive for backups). I really didn't think that the Ubuntu upgrade process would mess with this drive, seeing as the Ubuntu install was contained on an entirely different drive. Any safest way for me to recover this data? Data preservation is the #1 priority for me here. I need to copy all of this data over to my primary drive where Ubuntu is installed. After that, I can reformat this "broken" backup drive.
I have a removable USB pen drive, that all of a sudden, when it got 99% used, stopped working. When I try to mount it (manually) I get "can't read superblock". I know there is a ton about this on Google and I've read a lot of them, but most seem to be about formatting a drive, or fiddling in fstab. I'm trying to run fsck on it, and it finds errors, (among them: two FAT-tables?) but then it just freezes, and CPU goes to 100 % and I let it be like that for 4 minutes, before aborting. Scandisk in windows is rubbish (fails to start), and running "chkdsk /f F:", in windows, results in nothing, the shell crashes immediately. Is it normal for fsck to get stuck and just chew up CPU? It does not seem to be reading from the drive, according to conky. Also, is it possible to run fsck as normal user, (at my work)?
I recently installed Firefox 3.6 on Debian Squeeze. Everything went smoothly, but Firefox looks weird. The interface reminds me of Windows 98 and anytime I scroll through the menus the highlighter is grey and it makes things awfully hard to read. I'm not sure what could be wrong but I'm hoping someone here I'm not sure how to insert small images as url links so I'll just post links to screenshots I took for reference.[URL]Oh, and one other problem I recently discovered, flash doesn't seem to work. It works just fine in Iceweasel but I am told I have to install it in Firefox. I installed libflashplayer.so in /usr/lib/firefox/plugins but that doesn't seem to have helped. Come to think of it, it probably wouldn't since it's probably the 32-bit version I got from their site, I run on 64 bit.
I got a dell inspiron 1501 laptop with a 80Gb sata drive what is the best solution to add data storage space for someone that love to have multiples operating systems at hand Note: I use mostly linux so I won't need to change my laptop for many years maybe ...
