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 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
[code]...
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 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?
View 2 Replies View RelatedTrying 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 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.
View 7 Replies View RelatedI 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:
sudo fdisk -l:
Code:
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders

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:

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 try
mount -t ntfs -o rw /dev/sdb1 /mnt/exthdd
it doesn't give me any response so I presume it succeeded but when I try to touch it, it tells me it's a read-only file system
My karmic ubuntu studio will no longer boot. I believe I may have intermittent hard drive issues. I've backed up all my important files so I'm not extremely worried; however, I would like to try to get my setup bootable once more. I've reinstalled grub, and on trying to boot, I get the grub kernel selection. Regardless of what I choose, the system won't boot. I believe grub is alright, but something else is not. What else could I try to make it boot again? I've mounted the drive, chrooted to it, updated and upgraded, but it still won't boot. I may be doing that wrong, or there may be something else I need to do.

View 9 Replies View RelatedNot sure if anyone uses floppy drives anymore much. I know that most machines don't come with them anymore unless you ask for one.One of my machines [Machine # 2] has a floppy and I have never had the occaision to use it under linux [opensuse 11.2 currently]. Until now that is! I have about 30 floppies that I need to transfer the data from. I am able to mount the floppy drive and take data off the currently inserted floppy, but if I want to insert another floppy and remove the data from it, I must unmount and remount the floppy everytime. There is an entry in fstab:
/dev/fd0 /media/floppy auto noauto,user 0 0
and a mount point in media [/media/floppy] Is there something else I need to have in the fstab line for the floppy so that it will read automatically everytime I insert a disk?
I have a linux server running Red Hat Enterprise Linux AS release 4 (Update 8) that I need to do some unusual configurations to. I have a hospital application written using a database called MSE. Now the provider of this application says they will only support tape because of the fact that this system is using a specialized backup system. Basically the data is housed on raw_data blocks. So what I am looking to do is create a way to USE the SAN to present the server with Hard Drives and be mounted as if it was a tape. Has anyone tried to do something like this before? If so how did you configure that. One solution that I thought would be to just Present a 2TB lun and carve up several partitions cut not create filesystems on them. Then just create a symlink everynight /dev/rmt0 and rotate out the partitions.

We have a server at a friends house with a hard disk that's filling up so he picked up another hard drive.

View 2 Replies View RelatedI 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?
So I just reinstalled OpenSUSE 11.2 and I went from having 20-30 mbps speed to and from my 1 tb usb ntfs external hard drive to having about 1 mbps transfer speeds now. Is there any suggestions for how I can fix this? I know it can go faster, I just need to figure out how. and would setting acpi=off at boot affect this?

one would have to exclude certain folders / directories but would the backup be possible if the system is up and running in its native "live" state ? Which directories could be excluded ? Does swap need to be turned off ? I would like to make incremental backups on a separate partition of the same hard drive. I will endeavour to backup the MBR/ Partition table using dd.
View 6 Replies View RelatedI have never used rsync before, only DD. But from what I have been reading, rsync is better becasue it will basically mirror your hard drive, thus being able to run the cloned software from the new hard drive. My problem is I do not know what is the best commands or even the basic commands to use in rsync. I am trying to make an image from a external hard drive to a usb drive. That way my chances of messing up he original software is not as risky becasue I'll just restore the image onto another hard drive. Does anyone know the best script to have rsync make an image file of a hard drive and place it on a usb drive and then restore it?
View 8 Replies View Relatedi 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.
View 2 Replies View RelatedI was trying to create a partition on my hard drive on Linux using the GParted program. I noticed my hard drive had a key next to its name but could not find information regarding it online. I proceeded to unmount the drive and made 2 partitions. However, it game me an error saying it couldnt make the partitions. I turned my computer off thinking i would get back to trying tomorrow. Today i turn on my laptop and see the usual hp screen. But after that it goes to a black screen with a blinking underscore looking thing. It goes nowhere from there. It usually goes to a black screen after the hp logo, that says GRUB loading.
View 7 Replies View RelatedI 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

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.
