OpenSUSE Hardware :: Finding A External USB CD/DVD Read/write Device?
Jul 30, 2011
My 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 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?

I need to change a filename but when I boot up I get the message root device is read-only. Is there a way of changing this so that I can change the filename. I have a Mac Pro running Leopard OSX. The graphics card an NVIDIA 7500GT or driver has failed. It was suggested elsewhere that I change the relevant kext files to filename.kext.old, which I did, now when I try to boot start in OSX I get a message in various languages telling me to restart. I have tried booting in safe mode and from original Installation CD. In Safe Mode I get the same multi language splash screen, from CD I still have the graphic card problem, screen freezes and artifacts appear. So I boot up straight into CLI by holding down CMD-S hoping to be able to change filenames back but it says device read-only.

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 used dual booting with Windows Xp and Ubuntu 10.04. Because errors, I reinstall Windows and then I could not enter GRUB, and Ubuntu partition disappear. I tried to reinstall ubuntu using live CD but I could not detect last ubuntu partitions. After I installed fresh Ubuntu on new partition, I got error message like this:
Unable to mount floppy0 Mount: block device /dev/fd0 is write protected, mounting read-only Mount: could not determine the file system type, and none was specified

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
ehci_hcd28428 0
uhci_hcd18672 0

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.

On 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 initially thought the problem had to do with the Lucid Lynx upgrade, a lot of people have been reporting similar issues with drive mapping and things along those line. My issue is that an external drive, formatted in FAT32 appears to be corrupted, and overtime begins to read or mounts as 'read-only.'
What I've read, and deduced, is that this is ultimately and issue with the drive. I've backed it up, reformatted, and been able to write to the drive successfully, but I've been moving a lot of files (backing up) and the system has been reporting input/output errors in transferring some files (through the GUI).
The only thing I can think of, is that the device itself is corrupted or damaged, and that I need to be thinking of other back-up options for the future. Any suggestions on disk-doctoring? I'm hoping to do a clean-install of the OS once I back up my files manually.

i 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.

I want to use dual Monitor on Debian Lenny amd64, I have the nVidia 8600 GTS. I googled several times, I have to change the xorg.conf (as it seems) but I can't - no rights.
And there's another thing... I have a dual boot system along with the openSUSE HDD but I can't open it. And using openSUSE I can't read or write on the Debian's HDD. How can I change that?

I switched a external 500GB usb HD from FAT to ext4, because the box it's on no longer has windows.It mounts fine and I can read it - but not write.I have some inkling as to what to do, but prefer your opinions first.

Whenever I try to write to /opt, /usr/src, or /usr/local, I get "permission denied."
How do I fix this? The portion of the fstab for the filesystems in question is:
Code:
/dev/sda9 /opt ext4 user,noauto,noacl 0 0
/dev/sda6 /usr/local ext4 user,noauto,noacl 0 0
/dev/sda10 /usr/src ext4 user,noauto,noacl,exec 0 0
/dev/sdf1 /mnt/hd2 ext4 user,noauto,noacl 0 0

I can browse the iso image easily enough with a loopback mount, but when it comes to mounting the actual CD (which I did first), I get:
Code:
$ sudo mount -t udf,iso9660 /dev/dvd /mnt/dvd
mount: block device /dev/dvd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/dvd,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
/var/log/messages isn't very helpful, either:
Code:
Jul 15 15:15:56 bkorb-dt kernel: attempt to access beyond end of device
Jul 15 15:15:56 bkorb-dt kernel: sr0: rw=0, want=68, limit=4
Jul 15 15:15:56 bkorb-dt kernel: isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16
$ md5sum openSUSE-11.3-DVD-x86_64.iso
adf5d2a0a03c1e3aaf102fd6a4771b87 openSUSE-11.3-DVD-x86_64.iso
I burned it with K3B and it gets the same result trying to mount it. K3B seems to know that the image is an iso9660 and is able to display the various 9660 id fields just fine. It just won't mount.

I'd like to upgrade to suse 11.2 (currently using suse 10.2) and I've attached an external hard drive to save some data on, but it will only mount read-only, by either automount or by command line.
Here's the mount command I use (as root): mount -t ntfs -o rw /dev/sdb1 /media/ExpansionDrive
But when I look, permissions are dr-x------ 1 root root 4096 2009-12-05 13:38 cgate
Some related discussion on the opensuse forums has mentioned ntfs-3g, but my external filesystem type is ntfs. ntfs-3g is not available on my system currently or when I search for it with yast. I'm assuming I don't necessarily need ntfs-3g in order to mount my drive as read-write, but please correct me if I'm wrong.
How To Mount NTFS Filesystem Partition Read Write Access in openSUSE
However, these have not been specific enough to solve this particular issue. I can't think of any other possible problems other than the ntfs-3g.
Not sure if this is necessary, but I'm using SUSE 10.2, kernel 2.6.18.2-34, and the external drive is a Seagate 1TB.

I have a large external drive, which I connect to my laptop via a PCMCIA card - the machine is old and does not have USB 2.0 built in, so I use the PCMCIA card for that.
I am thinking of the following setup, and hope you can give me some tips on whether or not that would be a sound solution:
- designate a boot partition on the laptop's internal hard drive, which could store kernels
- make up a linux partition (or more than one) to use as root for any distribution on the external drive
- keep /home as separate partition on the external drive
My goal in mind is to be able to boot more than one Linux partition from the external drive. I can't make it through USB boot because the PCMCIA card is not recognized before a kernel module is loaded, and I can't use the internal USB 1.1 port for the external drive.
Do you think this is the way to go? Currently, I only have my /home partition mounted off the external drive.

[openSUSE 11.1, kernel 2.6.27.45-0.1-Default, Gnome 2.26.3] I have a problem where I have an external USB drive which mounts at boot, with /home aboard it along with several data-only partitions, and if I try to add another USB drive *after* boot, the system changes the device IDs previously given to the original drive. The already running sdb now becomes sdc. If a user or processes are attached to /home when this occurs they are left in the twilight zone and stuff starts crashing. An added weirdness is the newly added drive isn't stealing the sdb ID, the added drive becomes sdd instead, and nothing at all is left at the sdb ID.
Note:
- System boots from sda, a non-USB drive with the system as well as /swap onboard, that should be uninvolved with the problem.
- Among the 4 partitions of the boot-mounted USB drive there are 2 lux-encrypted partitions (ext3). One is /home (originally encrypted under 10.3 and added back after machine upgraded to 11.1) and another being a data directory (later encrypted under 11.1).
- The problem _may_ occur only when the additional added drive is also lux-encrypted, but this may or may not be always true as I have limited other USB stuff to test with, most of it is also lux-encrypted.

So my aim is to install openSUSEx64 11.3 onto my Macbook; but for whatever reason, upon boot-up, the system won't recognize the USB thumb drive with the expanded image of openSUSE on it. I followed steps in Terminal to expand the image onto the said USB stick and know it worked properly because Terminal said "Process Completed." Do I need a special type of USB thumb drive or am I missing something? I am using a late-2009 Macbook. By the way, these were the steps used to prep the USB thumb stick:
1. Open a Terminal (under Utilities)
2. Run diskutil list to get the current list of devices
3. Insert your flash media
4. Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)
5. Run diskutil unmountDisk /dev/diskN
6. Execute sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m
7. Run diskutil eject /dev/diskN and remove your flash media when the command completes

I'm trying to get a "network device" (read Internet Radio) to play the BBC stations. Apparently they changed their format late last year, and the radio (using Frontier Silicon Wi-Fi Radio Portal - Member Login) can no longer play the streams ("Network error" message). I thought I would try manually setting something up, but it is not easy trying to find what the actual streams are, when everything is playing in the iPlayer.
Is there a Suse/Linux app that can identify streams coming in, when being played in iPlayer..

I tried to uninstall firefox, which is what got me in this mess in the first place, the log claims it will remove ~240 mb but failes on a "E: Write error - write (28 No space left on device)" [URL] If I could juggle something onto an external hard drive so I can uninstall firefox I would be out of the wood. Failing that I believe a new install is in order.

I'm finding increasingly difficult to type because of neurological problems. I've just had a meeting with someone from university who said they could get me some speech recognition software to write assignments. I was wondering if anyone knows of any which will run on Ubuntu rather than just Windows. (I don't have Windows on either of my computers)

I did install QLandkartGT and the plugin to use Garmin with it and it looks like it work, but when I do press "Live Log" I get the error message; "Device Link Error. Failed to request real time position. Realtime thread failed. Failed to configure USB: could not set config 1: Operating not permitted".
I also get a similar error when trying to download tracks; "Failed to download tracks. Failed to configure USB: could not set config 1: Operation not premitted".
My guess is that Ubuntu do not allow programs to use the USB port, so my question is how I do allow this program (or all) to use the USB ports.
