Some moments ago, I plugged my drive into a computer with some strange data protection software. It turned my drive's filesystem into read only and now it can neither be formatted nor mounted with write option. I've tried
Code:
$ sudo dd if=/dev/zero of=/dev/sdb
but it doesn't work.
The problem is, the computer and the software that have caused this problem has lost forever.
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.

View 4 Replies View RelatedI bought an 8GB flash drive because my D drive doesn't read DVDs. Anyway, my goal is to install Linux ubuntu and have it be my OS (replacing Windows XP). Last night I went to the Ubuntu homepage and downloaded the Ubuntu desktop edition 32-bit and put it on my flash drive. I followed the instructions on how to open and run it, but I was never asked about whether I want Linux to run side by side with Windows or if I want it to replace Windows. It downloaded the whole program, my computer restarted and then (on a black screen) it asked if I wanted to use Windows XP Home Edition or Linux Ubuntu. It's really frustrating because it took a while to download and install it in the first place AND to top that off, when I tried to use Ubuntu it went to a black screen and at the top said that there was an error. So I uninstalled all the ubuntu program and software and now I have a clean slate and want to try this again. I am a complete n00b. Could someone please walk me through how I can go about downloading (w/ links plz), installing and making ubuntu my ONLY OS on my computer via a flash drive? I'm desperate and I don't want to go through all of that and make the same mistake again!

View 2 Replies View RelatedI have a linux server running ubuntu 10.04, kernel Linux server 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux. A few months ago I installed ubuntu to a USB flash drive (Patriot 16GB) and was able to successfully boot off it, and everything was running fine. Then all of a sudden I noticed that the root filesystem was read-only, and I saw errors in the kernel log:
[ 725.528732] sd 2:0:0:0: [sdc] Unhandled sense code
[ 725.528742] sd 2:0:0:0: [sdc] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE

I tried reading the drive to see if there was a problem with the drive itself:
root@server:~# dd if=/dev/sdc of=/dev/null
dd: reading `/dev/sdc': Input/output error

1966184+0 records out
1006686208 bytes (1.0 GB) copied, 2.12427 s, 474 MB/s
But the strange thing is that if I put that usb stick in a different linux server, I'm able to read the whole drive. If I run fsck, it fixes a bunch of errors, but when I put the drive back in the original PC it will work for a while and then fail with the same type of I/O error (not at the same offset though). I had this same problem occur on a different USB stick in the same server, I had thought it was bad media so I replaced it, but now the same problem is happening on a different usb drive. I have backups of the data, but I would really like to figure out what is causing this before I throw in the towel and buy a new PC.
I have a flash drive that I tried to drag a file to for printing later. I got error messages that this was a read only drive. I have 2 other flash drives that work. How can I make this usable again? Yeah Yeah why don't I just use one of the others you ask? well I can/did but I want to know if this one can be fixed as well.
I have the latest Ubuntu updates
This happens in my main computer with Slackware and Arch.
Code:

Also I have all files it asks for installed including dostools..Btw I used usb creator, then went to gparted and did something. The system is fat 32 now but with same message, not including ext4 part. Just the mount point message, and something about dosftools and mtools, wihich also are installed.
View 4 Replies View RelatedIt worked fine with the base install of 10.4 but somewhere along the way it stopped working and became read only.Autodetect and MTP modes cause only the Fuze to show up in Rhythmbox. However the track numbers are all wrong and some things are garbled. MSC mode, which I used in the past, shows the Fuze and card both in Rhythmbox and on the desktop. However it's in read only mode.

View 6 Replies View RelatedThe wireless connection works fine. The wireless switch automatically turns itself on every time I start the computer. However, after turning it off, I can't ever turn it on again unless I restart the computer. And because of this, the wireless connection is disabled until the next time I start the computer.I don't think this is a hardware problem because the switch can be turned on and off, although not in the way I expect.
I'm using ubuntu 9.10 on an Acer Aspire 4740G. The command [lspci | grep Network] shows Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01). the [rfkill list] command shows (when the switch is on)
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
and, as expected, shows (when the switch is turned off)
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
I just want to be able to turn the switch on or off at any time I want as long as the computer is still on.
This is very bad even in 11.04! I have an usb disk 40 Gb. And I was loading it with data real fast (svn). At once I could no more write, Read-only file system was reported. I reckon that problem from years ago on redhat, so I try to fix it. But It became worse. It was severe damaged. I created a new filesystem while the disk was out the usb-box and directly connected to de IDE. Started all over, and the error also. Tried to repair with no luck. It looks like the journal get overrun but I'm not sure. However I do think its reproducible. I did it 3 times now and now I am very sick of it. This is happening on a updated 10:10 to 11:04 system, a few weeks ago.

View 5 Replies View RelatedI am installing Ubuntu 9.04 Desktop on my system. using entire disk. my disk is new one. first time i installed ubuntu on it successfully, used it and installed new kernel and some upgrades. all were successful.but on installing some drivers, its files system corrupted. so I had the need to re-install the OS again. NOW , when i am installing the OS, it gives error "(Errno 30] Read only filesystem" explaining that either CD/DVD is corrupt or HDD is corrupt. temperature of the environment may be high. I changed the system , ehanged the environment, moved to some cool place, changed CD drive and CD (after making new one from ISO), changed the HDD but all useless, error is there,
while installation is in progress my sda1 is mount on /target. when i see fstab, here in the line of /dev/sda1 ,error=remount-ro is observed. sometime installation gives error no 5 sometimes it gives error no 30 but both the errors convey almost same message explaining that either HDD is corrupt or CD. As i have explained that I changed every thing including HDD and CD but the error is same.
I want to install 11.04 next to my working 10.04 system. First I need to make room for the new system so I have booted from a live cd and started GParted. In GParted the partition with the 10.04 system on it, /dev/sda1, has a red circle with an exclamation mark in it and I cannot resize it. When I doubleclick on /dev/sda1 there is the following warning
Quote:
Failed to change to directory '.'(Stale NFS file handle)
Failed to change to directory '.'(Stale NFS file handle)
Unable to read the contents of this file system!
Because of this some operations may be unavailable.
The following list of software packages is required for ext4 file system support: e2fsprogs v1.41+.
The 10.04 system is working and has worked like a dream for a couple of years and the machine has never had any other system on it. Why would the live CD not be able to read ext4 fs?
openSuse v9.3 (Yes, it's old)linux 2.6.11.4-21.17-smp i686At some time after July 28 the entire filesystem has become read-only. It was functional on July 28, the last time I logged into the machine and edited a file. Even as the superuser when I attempt to change, say, the permissions of a file, I get:
Code:

I have 64bit install with CentOS release 5.3 (Final)It's been stable for about six months. What happened a while ago is really weird, I haven't messed with anything lately but the entire /home filesystem became read-only. Can't write, can't delete to anything on /home. The other filesystems are fine. I am root, and the permissions look normal. My directories and files are writable and readable.
root@atlanta [/home]# touch foo.txt
touch: cannot touch `foo.txt': Read-only file system

I made a persistent install of Ubuntu on a flash drive. I made changes to that installation. The software (Unetboontin) sets this all up. I think it partitions it for you. How do I image that flash drive to another flash drive?
View 9 Replies View RelatedI accidentally changed etc., folder ownership, and now my computer doesn't even start up. I tried starting up in failsafe mode and changing the ownership from the root console, but somehow I wasn't allowed to do that. Then I loaded kubuntu from a live disk and I changed etc ownership to root. I thought that would clear up the mess, but apparently live disk's root is not equivalent to system's: when I try to start up the computer I get a message saying the filesystem is readonly. I'm not too concerned, because I have a complete backup, but I'd rather avoid the time of re-installing all my software again.

I'm attempting to build a load balancing cluster for shared web hosting clients and the only thing left is security. Given the track record with some of these sites, I don't trust them being centralized. We've had rootkits on some of the other servers that replaced system binaries, mostly ssh to capture passwords. I figured the only real way to lock it down tight enough to keep this from happening is to use a live cd for the filesystem or read-only toggle USB stick. But I also need to mount a rw drive to store the clients data and config files that are bound to change.
Is this really the way to go about this? If so do I simply make a live cd iso and edit the files within to handle mounting a rw hard drive and linking data and configuration files to that drive? I've considered just leaving all the data on the physical hard disk and mounting it as ro on boot for binaries and such but can't that just be changed with the right permissions?

This problem has arrived again.......I tried the same solution but didn't work out...the problem is described below.
I use Ubuntu 9.10 .
I did this in Ubuntu 9.10 live CD.
quote from terminal :-
ubuntu@ubuntu:~$ sudo mkdir /win

ubuntu@ubuntu:~$ sudo mount -o loop /win/ubuntu/disks/root.disk /vdisk

The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

Yesterday I post this note, because I've an urgent issue with the filesystem in opensuse 11.4, used like VMWare guest OS, over VMware Server 2 for w2k3 64bit like a host) opensuse 11.4 Filesystem goes read-only in VMware
But, Novell have a fix published for SLES 10, with the 2.6.16.46-0.12 kernel version .
I'm using a Opensuse 11.4 with the 2.6.37.6-0.5-desktop kernel version. May be related with the LSI virtual scsi hardware?
Because exists a fix for SLES 9, 10, RedHat EL 4,5 and Ubuntu 7.10, but doesn't work in opensuse 11.4
I have double boot (windows7 and Opensuse) on my laptop.
My problem is when try to login Opensuse says Read only file system.(While booting a lot of things FAILS(written red) because of Read only file system). So i can't login.
Cause of this problem is want to reach my Opensuse filesystem from windows7.I installed Ext2fsd software to windows7.After installed software can see my opensuse filesystem.But it looks empty from windows7.So uninstalled the software.
After that day try to login my Opensuse.While booting alot of thing fails to load it says "FAILED".and when entered my password after entering my username cant login it says ..... Read Only File System.
How can i make the filesystem Read/write permissions to my opensuse operating system.
I can't use any command beceause can't login. (I will try to boot with Opensuse Dvd)
I'm a issue with a opensuse 11.4 guest VM. The root partition goes read-only while the VM was running normally.
I note this /var/log/messages:
Code:
Aug 22 10:57:02 guest1 kernel: [508161.475307] mptscsih: ioc0: attempting task abort! (sc=dc29c5c0)

[Code]....
write a script that will check all filesystems to see if they are read-only.
I have come up with ...
df -h > /tmp/mount.lst
awk '{print $6}' /tmp/mount.lst > /tmp/mounted_systems.lst
This gives me ..
Mounted
/
/boot
/dev/shm
/proc
So now I have ..
How do I automatically get rid of the 'Mounted' header in my /tmp/mounted_systems.lst file ?
Also, I don't want to check the /proc filesystem, so how do I remove that within the script too.
Then I will run ...
while read dir
do
touch $dir/read_only_test
done < /tmp/mounted_systems.lst
If the filesystem is read only, I want that filesystem name to be listed into another file.
I'm running CentOS 4.3 on a VM which is an application server for Quinstreet. trouble is when i keep coming in during the mornings it seems to keep making this root filesystem read only. There is no pattern for this and neither is it clear in the messages log why this keeps happening.
