Hardware :: Ext3 Partition On External HDD Have No Write Access?
Apr 15, 2010
I have an Iomega External Hard Drive 1TB. Problem: Unable to write to Ext3 Partition. How I got here: Started off with going into windows and shrinking it's current NTFS partition down by 50GB. Then used an Ubuntu LiveCD to gain access to GParted and with that 50GB free I formatted it with an Ext3 system. It does this no problems. I then can't write anything to this partition? I've tried doing "chmod 777 /dev/sdb2" but it says Operation not Permitted.
EDIT: Need to be able to use it on YDL 6.2 on my PS3, YDL doesn't have NTFS write support and I want to transfer files larger than 4GB rendering Fat32 useless. No I'm not able to re-size or compress this large file.

Anybody know how to make an ext3 or 4 partition start up at boot with only the owner and its group having read and write access permissions.I don't want 'others' to have folder access. This is what i have done. / etc/fstab:/dev/sdb5/media/Data ext4 owner 1 2 The folder starts on the boot since it has been allocated a folder as u can see. Next i changed the the ownership and the group ownership of the folder:chown johnny:johnny /media/DataThe problem is that other users can few my partition since 'others' have read access. How do i change that to zero access?

I need to allow non-root users to read/write on an ext3 partition.
Below is the relevant output from fdisk -l
Code:
The partition in question is /dev/sda4 and it is mounted as /Data (setup during installation).

is there a way of sharing an ext3/ext4 formatted partition on an external USB drive between different users (uids) on different Linux machines without creating a group for this purpose, setting the group ownership of the partition to this group and adding each respective user to the group on every machine?This would mean that I need to have root privileges on every machine... which I may not have in some cases.I'm using the partition to store the code I'm developing on Linux and I would like the option to be safe... if possible.I could use a vfat partition but then I have no control of the rw rights + I cannot develop directly in the dir: I would always have to tar.gz the directory, extract, work, tar.gz, copy to the external drive.

I'm trying to backup netbook files to an external optical drive. I can read discs but not write. A while back I tried using K3b but it did not see the external drive. Now it does, but tells me write access is needed and quits. I am in the cdrom group.

I have an HP laptop with a recently installed copy of Mint 8 KDE Community Edition. I created the initial admin user account ("joseph") when I installed.
I had an existing home directory under a different name from another installation, so I added a user with that name ("joe") and imported a copy of the original home directory. The user "joe" didn't have the same admin privileges as the initial "joseph" account, so I added "joe" to the sudoers file and the same groups as the initial admin user.
Everything works perfectly under this arrangement, for the most part. Now here's the problem:
I have a T-Mobile G1 phone that uses Android. I've rooted and ROM-modded the G1, and have the microSD card in the phone set up with two partitions. The vfat partition stores all the photos, music and other stuff the phone needs. The ROM mod allows me to store apps on the SD card, so that second partition uses ext3 for its file system.
When I'm logged in as the admin "joseph" account and I insert the SD card in the laptop's card slot (or plug the phone into the USB port), the SD card can be mounted, and I have full access to both card partitions. I can see all folders. I do this to backup the contents of the card to an external drive (especially the apps in the ext3 partition, since that's been trashed on me once before on the phone).
However, when I log in as "joe", I cannot view the contents of the ext3 partition at all. I can see the vfat drive fine, and the ext3 partition mounts, but with user/group "joseph/joseph." When I open Dolphin to view the mounted ext3 partition, I get the error "could not enter folder /media/disk-1" at the bottom of the view window in Dolphin.
Here are the relative entries returned when I run "mount" to view the mounted drives:
/dev/mmcblk0p1 on /media/disk type vfat (rw,nosuid,nodev,uhelper=hal,uid=1001,utf8,shortname=mixed,flush)
/dev/mmcblk0p2 on /media/disk-1 type ext3 (rw,nosuid,nodev,uhelper=hal)
Note that the uid listed on the vfat mount is 1001, which is the gid for the "joe" account.
I know there must be a configuration setting somewhere that will allow the ext3 partition to automount under the "joe" user account. I suppose that using the admin account to change the permissions would be the easy way to do this, but there must be something that would do it automagically. I've ripped through all the config files I can find, but can't seem to find anything that would help.
All I'm looking for here is enough access to be able to copy the directories on that mount to my external drive.

I have recently installed Debian on my NAS server. I have also configured Samba for sharing the home directory of a nas user i.e. /home/nas To this directory I have read/write from a windows machine using the nas user credentials. When I mount my RAID partition /dev/md0p1 to the /home/nas directory, I then realize that all content in this directory (files and subfolders) is only owned by the root user. When trying to access from the windows machine the /home/nas directory, I do not have any write access, only read. I have tried both the nas and the root user credentials.
I have also attempted the change the ownership of the mounted RAID partition to the nas user with the -R recursive option, but I get for the internal files/subfolders an error "operation not supported".
How can I overcome this problem? - Is there something not done properly in the /dev/md0 array definition (i.e. ARRAY /dev/md0 level=raid1 num-devices=2 UUID=bddf8b69:c97967b5:cb104784:7fef7cc3 )?- Is there something not done properly in the /dev/md0p1 mounting (i.e. mount /dev/md0p1 /home/nas)?- Should I do any extra configuration before the mounting etc? I would really appreciate any kind of help I could get.
Some background info
b) After OS boot, when I do a:
# cat /proc/mdstat,
I get:
Personalities : [raid1]
md0 : active (auto-read-only) raid1 sda1[0] sdb1[1]
4200896 blocks
unused devices: <none>
[Code]...

I have installed Ubuntu 11.04 64 bit desktop version on ext4 partition without swap. I have maximus iv extreme motherboard with 8 Gbytes RAM. Using 3 internal ntfs formatted hard drives and 3 external ntfs usb 2.0 hard drives.When I am trying to copy or move files FROM or TO any ntfs partiton it is 90 percent chance it is going to freeze.For copy/moving files I am using krusader run as ROOT or as user without root privilege or Nautilus as user without root privilege. It wasn't possible to switch to another terminal - it simply does not react on keyboard or mouse input and only hard reset is possible (scares me because of ntfs disks)From this point of view I have suspicious on ntfs driver but:I am completely beginner in linux and I am looking for help to navigate me how to investigate to find what is causing the problem eventually to solve it?
According to my experience it seems to does not matter if hard disk is internal or external connected through SATA II or SATA III or USB 2.0. I have tried to manipulate with ntfspartitions through the vmware or virualbox or truecrypt software or just do a simplecopy/move files - it have has always the same results - freeze. There is not possible to say how long it is going to work properly and when it is going to freeze - sometimes it's working hour, sometimes it's working couple of seconds - no matter if it is read or write operation/s within ntfs partition.

Recently my laptop broke down and wont start up. I'm currently trying to recover my files to my mac with an IDE to USB cable. It recognized my windows partition fine and I was able to get all my files off of that, but the majority of my stuff is on the ext4 partition that I have on it. Does anyone know how to access the ubuntu partition of this hard drive from my mac?

I have a netbook with Ubuntu 10.10 installed in it,and a Pc with also ubuntu 10.10 in it , but x86_64.
I want to copy some iso files and data from my user home directory on the netbook , to the user home directory of the other pc , using a 8 GB usb formated in ext3 with gparted in my pc.
One iso is a windows 7 one to burn then with K3b , as i need to have windows installed in that box. Also of another iso that i have to burn too (windows 7 recovery disk) , and 3 anti-virus trials for windows.
As the usb is owned by the root (or more properly the mounting point,no?), and i can't use my user to copy data to it i usually do :
Usually , what i use is "sudo nautilus" then go to the place where is the data , copy it , and paste it then in the usb. Then in the other pc i do a chgrp and chown to the iso or file.
But , perhaps this is not the better approach. I have investigated a bit , and i think that i have found a better way , but i have some dudes.
The method is change the owner,group and permissions of the mounting point:
Code:
cd /media
ls
umount /dev/sdb1
sudo mkdir usb
[Code].....
If i do this steps in both computers, with each user,in the netbook i can copy the iso to the usb (as fox can write to the mount point of the usb ), but can the other user in the pc 'mulder' read the iso , so be copied to /home/mulder, and then be able to burn it in k3b with success ?
I suppose that having 766 , it should be able to read it , but would have the own of the file ?
How important is not to only be able to read it , but also own it ?
I suppose if the user ID is the same , wouldn't be any problem ,as each ubuntu would supose that the file is owned by their user.
Perhaps the user name change,but if the ID is the same , the user is the same for ubuntu , not any different, no ?

I usually repartition a disk by backing up, deleting the partitions, formatting them and repartition. I just did a 200 gig backup (so i am safe) and i want to join 2 (ext3) partition together, sdb1 (data4) and sdb5 (data5) into one big partition. Is there a way to do it without scraping the data in sdb5 (data5). It would save me from rewriting the data back to that new partition (200 gig is time consuming).

I was having trouble with an old lvm partition so I pulled all the data off and now want to re-partition it as an ordinary ext3 partition.
But gparted offers only Logical Partition for that partition. How do I convert that partition to a Primary or Extended partition - and which do I want?

I switched over from Windows to Linux. I have an external drive that has basically just media files on it. Are there any advantages to converting this to ext3, or should I just leave it as ntfs3?

A friend of mine and I bought an external hd (WD Elements 2TB) and formatted it in ext3 as root. Now we want to use this hard disk in more than one systems with different usernames. So we did "chmod -R 777 /media/ VolumeLabel" in all the systems.But we want the hd to pass around. So its a little bit inconvenient to do chmod all the time. So what should we do to make the access for the hd universal in all the systems that we plug it in?

I have a Westel 1 TB external hard drive and when attempting to partition it, the partitioner never finishes refreshing the device. I've tried gparted live, opensuse, & ubuntu; and none of them finish refreshing the device.
Another issue is, I have 200 gig of music & movies that can't be wiped out because I got no room elsewhere to move them to. I would like to set a partition of 750 gig for the ext 3 and leave the rest for ntfs.

I have a external HDD with eSATA and USB connectors available. I want to use this HDD to store my backups. The HDD should be encrypted (my main system is as well).
So here is what I did so far:
1) I used the following code to create the encrypted LUKS partition with EXT3 Filesystem:
Code:
cryptsetup -c aes-xts-plain -s 512 luksFormat /dev/sdb1
cryptsetup luksOpen /dev/sdb1 luks
mkfs.ext3 /dev/mapper/luks
The system always hang when I executed the "mkfs.ext3..." command, so I switched the HDD from eSATA to USB and then it worked fine.
2) When I switched on the ext. HDD the first time, the drive was recognized automatically and Nautilus asked for the password. I typed it in as checked the checkbox to remember the password in the future. For the backup I use a nice script that I found in another forum, where I can define a mountpoint and then the script will check for previous backups and only make a incremental backup based of the latest version. The script also mounts the drive automatically. In order to always have the same mountpoint, I want to make an entry in the /etc/fstab using the UUID of the ext. HDD.
Whatever I tried, it doesn't work. What am I doing wrong? Here is my current /etc/fstab
Code:
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# / was on /dev/mapper/ubuntu-root during installation
UUID=2ea47421-73ce-4c66-9606-8a1db81ae640 / ext3 relatime,errors=remount-ro 0 1
# /boot was on /dev/sda1 during installation
UUID=dbdeb793-1d4e-43ea-8986-7b37fdbc9674 /boot ext3 relatime 0 2
# /home was on /dev/mapper/ubuntu-home during installation
UUID=42702091-83e6-43eb-aad1-108f43eedf9d /home ext3 relatime 0 2
# swap was on /dev/mapper/ubuntu-swap during installation
UUID=e225bcf9-908b-4226-a963-6b02ee658df1 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
# Eintrag wegen iPhone
none /proc/bus/usb usbfs devgid=125,devmode=666,nodev,nosuid,noexec 0 0
# external HDD
UUID=913977f7-8fa6-416f-af79-b5f913b68f53 /media/backup-hdd ext3 noauto,users 0 0
I made the "none /proc/bus/usb..." entry because it was recommended to ensure correct behaviour of the iPhone. Not sure if I need it though.
I created the mountpoint with this command:
Code:
sudo mkdir /media/backup-hdd
Now it seems the mountpoints owner is not root - strange right?
Code:
2 4 drwxr-xr-x 3 michael michael 4096 2010-01-15 02:45 backup-hdd
How should I mount this drive correctly? It will be automounted as every USB device, but that should not be the case. I want the script to mount and unmount the drive.

I'm trying to format a 500 GB external drive with gparted in ubuntu 10.10 (I searched & didn't see this issue in the forum). I set up and formatted two partitions, one for fat32, and the other with ext3, which appears to format ok, but I can't use it. Both partitions show up and appear to mount, but the ext3 partition won't accept activity (make new folder, copy in files), while the fat32 partition works fine. Both partitions show up ok when I query in terminal "sudo fdisk -l"

After a near miss with my 1.5TB, RAID5 file server, I have decided that I need to backup my data to an external hardrive periodically.I have been looking at rsync but the question I have is: Do I format the external hard drive in EXT3 (the sameas my fileserver) or NTFS?All my main machines are Windoze, but the file server is Ubuntu with a samba share.If my server ever went belly up, I would like to be able to access my data from the external hard drive. I guess if it's in EXT3 then windows would be clueless... I would either need to fix the server pronto or access it with a live CD or something.What would I lose if I used NTFS instead of EXT3? I think I would lose permissions and possibly ownerhsip information - are there any other issues?

I am wondering if any of you technical guys would be willing to format my Western Digital external USB 1.5 TB Hard Drive to Linux EXT3. I am naturally happy to pay for your time and trouble and for postage. The WD drive is for storing video footage and will be connected to my Humax Freesat HD Digital TV Box(not a computer), and the Humax Box will only record high deffination programmes in EXT3 format. I've tried to do the job myself with my PC, but have failed to change my system to format in Linux.

I have 2 external drives that I'm using for movies and they're both formatted to fat32. The problem I'm experiencing now is that some of the high quality mkv files are not able to be moved to the drive because of fat32's limitations.
I'd like to convert to ext3 (or 4) and I wanted to check to see if I can do it without having to reformat and without loss of data.

I have a Western Digital My Book World Edition external harddisk with blue rings. I filled it up and now want to delete the data and start over. I'm set in my ways and have been accustom to reformatting harddisks periodically (sector maintainance, etc.) It's worked for me as I've luckily have not had a disk crash in 25 years.My webapp is not helping me with the reformat and neither is Western Digital tech support. I've heard that it was factory formatted with something called Linux ext3. Does this make sense? Has anyone had any experience with reformatting external harddisks being used as a NAS (home use).

i needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.

I'm running ubuntu 9.10, and created a softraid5 with no problems. Now i need it to automount with user read/write access, and i need to make some network share folders. My fstab has the following line for the raid:
Code:
/dev/md0 /media/raid auto rw,user,auto,exec 0 0
After i mounted it, i changed the permission with:
Code:
sudo chmod 777 /media/raid/
So now i can create folders and files on it.
Then i created some shares, one with guest access and other with no guest access.
Now the questions:
1) If i access the guest shared folder via WinXP, i create files and folders, but they appear locked on ubuntu, so i cant access them until i change the permissions. If i go to proprieties/Permissions, the owner is "nobody".
2) What password do i need to use on WinXP, and i try to access the non-guest shared folded? Do i need to create a user just for that?

I am dual booting OpenSuse 11.2 and Windows 7 both 64bit on my PC. I've got VMware workstation installed on both. I've got few virtual machines which were all created in Windows VMware and they're all stored on a separate partition. I can access this partition and all other NTFS partition from Suse but with read-only permissions. That means I can't run any of these virtual machines from Suse VMware. Is there any possible way to make all these drives writeable from Suse? I'm really hoping someone would be able to help me. I've got a lot of googling and have even searched this forum but without any luck.

I just made a new storage partition and formatted it as Ext3. Now, this particular partition is shown and can be read at the terminal "fdisk -l". However, unlike in my Mint 7 partition, it does not show in my Fedora 10.
Code: [jun@localhost ~]$ sudo fdisk -l
[sudo] password for jun:
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xc5e3f820
[Code]....
This partition can also shows be seen in gparted in Fedora. However, even in the "Places" tab, it does not show.

I have an 80 GB XFS / partition which is dying. Got some errors like this:
ata9: SError: { UnrecovData Dispar BadCRC Handshk }
It's not a problem to create another partition, I've got 2 500GB and 2 1TB disks, all EXT3. I've also 2 80 GB disks, 1 for / and 1 for /home. I will remove the 2 80 GB disks but I have a lot of stuff compiled myself. I use openSUSE 11.1. Is it possible to create a 80 GB EXT3 partition on each of the 500 GB hdd, 1 for / and 1 for /home and move the data to it? must it be done with the DD command or can I easily copy everything within a live-cd. The /boot and swap are already on one of the 500GB disks, and there is no bootrecord on the 80 GB disks.
