I am trying to install the reiserfs drivers to read/write to my external drive. But keep getting command not found. Although the system can get man pages for modprobe.
modprobe reiserfs
bash: modprobe: command not found
I also need to know how to add myself to the sudoers file. I have already tried visudo but this has not worked.
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
I am using sun micro system. We have installed fedora in that. I want to know how to give R/W permission to a external hdd...

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 installed Fedora 12 on an external hard drive. Everything went fine with the installation and it was working perfectly until i tried to install my video card drivers. I have done this many times before and it has worked. I have an ATI card. Anyway after installing the driver i rebooted and now when it starts it show the loading bar on the bottom but then nothing happens its just a black screen!. The worst part is that when i go into windows and my external is plugged in windows wont read it and i have very valuable data on it. I go into disk management and it shows up but windows says that its empty. which is obviously not true because Fedora starts to boot. I really just want Fedora off my external and for windows to read my external with all the files still on it. Is there a way to get by that blank screen?
View 2 Replies View RelatedI have shared two external harddrives via samba on ubuntu, but only I can access it. The reason being is because I have logged into linux, and become the owner of the external hdd's. On the permission properties, I can see that the group I have created every other user under has "No Folder Access", and if I change this it reverts back instantly. So frustrating, I've tried to chmod it which hasn't done a thing. The owner of the external hdd's seems to be the only person who can access it over samba.Is there anyway I can get normal users to just read and write to external hdd's?
View 9 Replies View RelatedMy wife is purchasing a netbook with no internal CD/DVD writing device, so we plan to purchase an external CD/DVD USB-2.0 read/write device. Our local PC shop has the following 3 external USB-2.0 DVD read/write devices:
(a) Samsung DVD-Burner SE-S084F/RSBS [not listed on Samsung site - too old ? ]
(b) LG DVD-Burner GE24NU21 USB2.0 [not listed on LG site - too old ? ]
(c) Super-Multi Portable DVD Rewrite (GP10 Lite USB2.0 Slimline) GP10NB20 (mentions Mac OS/X support, which is encouraging)
None of those are listed in the openSUSE HCL. Has anyone successfully used any of these with GNU/Linux (my google surfing on this revealed no GNU/Linux complaint nor any success stories) ? Or is there another such external USB-2.0 read/write DVD burner device that is recommended ?
I am running Lenny. USB storage devices are painfully slow, if the data to be copied is above 4GB it works on transferring for more than half an hour and then comes up with an error dialog(saying something like file size is too big). The problem exists in both read and write.
I did google a bit and here is the output of lsmod | grep hci

I am unable to install CentOS V5.4 on my work station.
After collecting the config info (root password, etc.) the installation immediately gets disk write errors while doing PVCREATE.
I'm installing from the DVD to the 136GB SCSI drive. The drive is known to be good and is writable as a Windows
volume.
The scsi drive is the only drive selected for installation.
I've selected to delete all partitions on the volume and install default configuration however the new partition is not created. code...
My external HD where everything I backed up from my previous install will not mount. It shows up in lsusb, but when I do dmesg:
Code:

Also of note, my main filesystem is reiserfs, so there isn't a problem of not having reiser installed.

I have a computer with no floppy drive (x64 ubuntu lucid installed) I have a program (wine windows xp) that will only save data and export data from/to a floppy drive. I found information on setting up an emulated floppy drive. i.e.
sudo dd bs=512 count=2880 if=/dev/zero of=imagefile.img
sudo mkfs.msdos imagefile.img
sudo mount imagefile.img /media/floppy -o loop
I modified the winecfg to include under the drive section A: /media/floppy. Problem is I cannot write to the drive as a normal user. I have tried everything I know but only root can read write to the drive. Is there someway to set up this emulated floppy to allow me as a user to write and read contents.
I have an external hard drive connected via usb cable - /media/New Volume - and mounted in Ubuntu 10.04. How can I "write zeros" to this drive or maybe write random characters in an effort to wipe data on this disk?

View 7 Replies View RelatedOn one of my machines the DVD/DVDRW/CDROM drive appears as /dev/hdc and is not identified as an optical drive by HAL. It is owned by root: disk and thus no users get permission to read/write in the device (not even those in the cdrom group). This stops playing DVDs, ripping CDs, no notifications appear when a disk is inserted, etc. etc. When I set the permissions for all to read/write from the device then users can access but still no notifications are shown.
On all my other machines the optical drive is identified as /dev/sr0 and is owned by root:cdrom . All have Slack 13.1 . Previously with Slack 12.2 this machine still had the drive in /dev/hdc but the permissions were right (I think because I added it to /etc/fstab with options for users to access it). I believe the problem is down to HAL not setting this drive to the correct group, but how do I fix it? I hate HAL, it has a mind of its own, just like in the scifi movie
I installed CentOS 5.5 32-bit with Gnome and want to use it as a file server. The volume I wish to share is a 1.5TB NTFS partition stored on a USB drive. I installed "ntfsprogs" and "fuse-ntfs-3g" to get NTFS support. However, I only have read access to the volume.
How can I fix this and get Read+Write to the NTFS drive?
I'm trying to back up my hard drive to a 2 TB WD external so that I can do a clean install of 10.10, however I'm getting tremendously slow write speeds. It hovers around 1.5 MB/s and steadily slows from there. It tells me it will take 150+ hours to transfer 400 GB of data.
I have a AMD quad core processor and 8 gigs of ddr3 ram... USB 2.0... I feel this should go much faster.
Short version: How do I reformat an external hard-drive (read-only, NFTS) so that I can rw to it.
Long version: I had a self-built Ubuntu desktop that is now dead. I have pulled out the hard-drives and have bought one of the connector's to convert the SATA cable to USB so I can put the data on my Mac. Unfortunately, my Mac is not able to read the hard-drive for some reason... So, I've decided to boot my old Ubuntu laptop to pull the files from the SATA drive to an external drive then hopefully connect that external drive to transfer the files to the Mac. The external drive is currently formatted as NFTS and I'm unable to reformat it with gparted--I'm guessing that's because it's read-only mode...?
Ubuntu ext3 SATA -> connector -> Mac OS X
or
Ubuntu ext3 SATA -> connector -> Ubuntu ext3 laptop -> external NFTS HD -> Mac OS X
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?

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?

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)

I have installed a cable that connects from the CPU's SATA motherboard connection to a removable drives' ESATA connection.I would like to be able to swap drives on the ESATA connection and have all users be able to read and write to these drives.I have created the directory /archive/ where I would like the drive(s) to mount.The drives are all formatted Fat 32 - but in the future I may use HFS for formatting.When I used the command (as root):mount /dev/sdc1 /archivethe drive was mounted (but read only)What can I use in my /etc/fstab file that will allow drives to be mounted and unmounted by all users on the system? (both reading and writing)Also, will I be able to mount and unmount these drives without shutting down? or will I need to reboot every time I want to change drives?

I'm using Debian Etch.

Writing to etrenal USB hard drive doesn't work:
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:
sudo fdisk -l:

I bought a Western Digital 1TB external hard drive to use with a Gentoo build. It connected beautifully, mounted visibly but despite being mounted read/write any attempt to write to it produced the error "read-only file system". I chased a number of red herrings before I found that the drive comes with an NTFS filesystem and NTFS support in my kernel was set to read-only, which I think was a default setting. Simple fix was to install a different file system - as it was a new drive there was no old data to lose.
View 1 Replies View RelatedI am new to Centos and linux in general. I have just got myself a Dell 1950 server with 2x 1T SATA2 hard disks in it. now the server comes with a PERC5i Raid card with 512Mb. Well I put these in raid 0 and the raid card initilzed the disks to 128 writeback and read ahead. When I loaded centos it did not recognize the dell layout so therefore wanted to initalize it again, so I done this as it wanted. Now I created a 80gb boot and o/s partition and a 100gb swap the rest was created into LVM space to run solus vmwear. But I found the raid 0 to be getting extreamly slow read and write speeds.
Example same disks
Desktop PC max 214mb/s windows vista 64
Server with centos 104mb/s
Now I am not sure but I am told that I need to align the o/s with the raid card settings but I have no idea how to do this. How to do this in plain easy step by step instructions. I mean how to calculate it, how to format the disk this way, and what files to edit where if needed. I have spent hours trying to figure out why my raid 0 is slower than a single disk.
