I am trying to use my external hard drive to store webpages and on the webpages it is uploaded to the folder. When i navigate to the address it says it is forbidden. I also noticed that it would not let me upload files to the folder it says i do not have permission. Can someone help me get passed the barriers. The hard drive is ntfs.
View 7 Replies View RelatedI have Seagate Freeagent Go 500GB external hard drive that I use for backup. I wanted to resize the partition so I used GParted to shrink the 500GB NTFS partition to 400GB. The other 100 I wanted to encrypt and use for some other more important files. For some reason, the shrink failed and I disconnected the hard drive and reconnected it. I didn't see the icon appear on the desktop. I went into the Disk Utility to discover that GParted's shrink error deleted all of the partitions on my hard drive. So I created a new 400GB NTFS partition and put back all of my files. The other 100 is unallocated currently.
It will normally mount automatically and show up on the desktop but the hard drive won't mount without me going into the Disk Utility and mounting it through there. I can't even mount it from the Terminal with root privileges. It gives me this:
Quote:
sudo mount /media/My Data
mount: can't find /media/My Data in /etc/fstab or /etc/mtab
Now, I can unmount with root privileges and I can unmount it from the Disk Utility. I can browse and edit the files within. But I can't unmount it from within Nautilus or on the desktop (the Safely Remove Drive option is not there).
The new 400GB partition also isn't detected by GParted. It just shows the whole drive as unallocated.
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?.

This is Mushtaq here. I am using CentOS 5.3. Everything works fine regarding Hardware Support except of External Hard Disk. I have a HDD Western Digital 80 GB in USB converted case. Its working fine under WinOS, Fedora 10 / 11 / 12 + & RedHat Enterprise Linux. But CentOS is unable to access it even it does not detect it (fdisk -l command is used to verify the connected disks). Can any one please help me in this regard, I am fed-up of this situation.

View 3 Replies View RelatedI 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.
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'm trying to create a CentOS based liveCD that mounts a NFS share and executes one script there. The NFS never mounts altough while logged I can mount it with the very same command that I use in the KS.
In the %post I have :
%post --log=/tmp/post.log --erroronfail
mkdir /mnt/nfs
mount -o nolock 10.23.1.1:/csc/RemoteHome /mnt/nfs
I added the --log in order to debug, but nothing is written in /tmp/post.log. I tried redirection on the mount command with >> /tmp/debug.log but this is not written. Maybe during the post sequence /tmp is RO ? Anyway, I tried with ifup lo, service portmap start in the %post, but doesnt change (I even have a service : command not found in the live cd creator output).
Here is the remainder of the KS :

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:

missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

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 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've updated my openSUSE 11.1 to 11.2 using installation DVD. After that, as system boots, I started to get lines like:

I have a flash drive that I use to sync my work- and home-computers. Rsync has occasional issues syncing between FAT32 (which I use on my flash drive b/c it's universal) and EXT3.
I decided to create an EXT3 partition on the flash drive in an attempt to alleviate the rsync woes. My problem is that when I create the partition using GParted, Ubuntu auto-mounts it with Root as the owner. I had GParted check the drive, and it found no errors to repair.
One other weird thing is that the EXT3 partition shows 84.7MB being used immediately after creating the new partition.
The FAT32 partition mounts fine, is read/write, and only shows 4KB used after the new partition scheme.
I tried doing new partitions a number of times, with EXT2, EXT3, and EXT4 just to see if that mysteriously made a difference. Each time that partition would mount w/ Root as owner.
I have multiple ubuntu machines and I connect to one through an NFS share. I have done this for a few years without issue. However, since re-installing ubuntu and upgrading to 10.4 I have a problem with my system hanging when the remote shares are lost.
Basically, I can power down the machine downstairs, and my main machine then has a fit. I can not open any folders in ubuntu, nor can I shut down. If I try and shut down the system hangs, last time it hung for 8 hours before I had to kill the power.
These are the lines in my fstab
I don't know what I've done wrong, or how I can prevent this from hanging. I have googled the heck out of this as well and can't seem to find an answer either.
I am working from RHCE Study Guide 5th Edition by Michael Jang. Lab 1 for Chapter 6 says that I should be able to mount a remote NFS share as an ordinary user under their home directory.
However, mount requires root unless it's defined in /etc/fstab with the appropriate options. So would the following never work for a user?
Code:
I could define it in /etc/fstab, but then I would have to specify a "general" mount point for the mount, like /mnt/nfs and not specific to a user like the lab suggests above.
Is the book wrong on this? Even the answer for the lab makes no mention of using fstab to mount as non-root user and the above command is correct according to the solution.
Ive seen this a hundred times while searching google but I can't seem to get any of the fixes suggested to work for me.
Here are the specs code...
I have other servers on the same network with the same software/hardware that never loses its mount to the windows share, and nightly backups are run through those mounts. So why does the mount on this machine fail when we do a push? The only conclusion that I can come to is there is some sort of time out on the windows server that causes this. The other servers that have this same type mount use their share every night, where as the share on this server gets used once or twice a week. Once the mount hangs I can not unmount it, I have to reboot the server. Once the server is rebooted the push works fine. But then the next week when a push is tried it hangs. What else can I check?
UPDATE: I've also tried NFS mounts and autofs mounts and they hang as well
I enabled logging by echo 1 > cifsFYI and this is what I see in var/log/message code...
Ive removed the actual file names for security concerns. Any one have ideas as to why this is happening? The only other thing I can think of to try is to swap out the NIC but it's at a remote location so I can't do that right now.
