I installed Ubuntu a few weeks ago and now, It looks like I can't get anything to work through my USB ports. Thumb Drives, extermal hard drive, iPod.... nothing works. When I first got ubuntu, I was able to get a few things to work, but then it just stopped.

I have a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.
View 1 Replies View RelatedI was able to read and write to my USB thumb drives until I mounted a USB thumb drive with an autoinstaller, and every since then all of my flash drives show up with the owner as "root". I've tried changing the owner, and I'm not allowed- even with using sudo chown.
I don't get an error with that, but the owner isn't changed. I can read from the drives but not write to them. (I found that I can copy to the flash drive by using sudo cp, but I want to get away from command line stuff. I have too much to do to be constantly dropping into terminal mode!)I had no problems until the very minute I mounted that flash drive.I've read a few threads, and found other people with symptoms similar to mine, but when I try the fixes suggested, they didn't work.I've also not been able to locate anything that the flash drive autoinstaller changed or put in, but I must admit that I still am a relative newbie to Linux (been around computers since the early 70's, around Windows since 92-93, around OS/2 94-96, and Linux for only a year or so- and haven't learned that much command line stuff yet!).
Is there any performance degradation or complications that arise from having Linux installed on a separate, physical hard disk from Windows in a dual-boot setup? I have a computer that I'd like to dual-boot Ubuntu and Windows but the current hard drive is quite fragmented and the Windows partitioner won't allow me to make a partition large enough to comfortably run Linux+several gigabytes of media that need to be stored. The rig, however, may have room for another internal drive, so I thought that having a separate physical disk reserved completely to Linux would be an easy solution. The tech guy at the local computer store suggested there might be difficulties with this configuration because one drive needs to be the "master" and the other a "slave", resulting in boot complications.
View 5 Replies View RelatedI've installed Fedora 10 short time after it came out. Now I am having some problems unmounting thes drives on restart or shutdown. It hangs at the stage of 'unmounting file system'. I've looked into this matter and discovered that those drives are automatically mounted and shown on the Gnome file browser. As the /etc/fstab indicates, it is not mounted by it. I must have done something to have all the hard drives shown in the file browser and now Fedora seems to be unable to unmount them.

The drives all have root:root file permissions and cannot be changed to my normal user "ramack". There doesn't appear to be any errors and it is limited to only this Acer Aspireone Netbook running i386 Testing. I don't have anything in my fstab in regards to mounting usb drives.

All of a sudden my Debian 5.05 system quits working in several different ways.I think it started after I was trying to set up Virtual Box. My first symptom was that when I was trying to convert a dd backup file to a virtual hard drive, the conversion program, part of the virtual box package, told me I was not part of the virtual box group. So I added myself. I could never get past this error message, so I gave up and figured I would google the answer later.
Next time I am on, my sound card does not work. The volume control in the Panel was a red X next to it and complains about the gstreamer not being present. After another round of google I find the brute force solution of giving everybody in every group rw access to everything in /dev/snd. This works. (My main user account was already part of the audio group. I added a new user and specifically added him to the audio group. Nothing. Only root had audio access.)
At about the same time I discovered I could no longer play DVDs. When the movie player starts, it says I may not have permission to play the movie. mplayer claims there is no stream found to handle url dvd://1Also when I add a thumb drive, the file system is read only.
For what it is worth 2 hard drives have Kubuntu 8.04 and the 3rd has Mandriva Spring 2008. Tuesday was the last time I had used Pidgin and everything was fine. Wednesday when I booted the computer I noticed that the Pidgin icon in the sys tray looks broken. I click on it and it shows "Pidgin is available" "connecting" and that's it. The buddy list is empty. Went to my other Kubuntu hard drive, same thing, went to my Mandriva hard drive same thing. Installed Kopete on this hard drive and it shows no one available.
I did a search here before posting and found nothing.
The software: Ubuntu Server Edition 9.10.The wetware: A programmer doing his best (read: ignorant, shitty) as an ad-h.When I plug the USB thumb drive in, the install OS gives it a drive letter -- /dev/sdb -- and it pushes the original /dev/sdb down to /dev/sdc. The installation works without a hitch, and GRUB2 installs, dutifully pointing the root at /dev/sdc1 instead of /dev/sdb1.I let GRUB2 start normally ("drive not found"), holding the <shift> key to get to the "rescue>" prompt.From there, I issue "ls" to discover that GRUB can NOT see /dev/sdb, and I can tell that because what is showing up as (hd1) does NOT have three partitions as it should.GRUB2 sees a total of 16 drives, not 26, and one of the drives it sees is "fd0" (there is no floppy drive).Issuing commands like "set prefix=(hdx,y)" and "root=(hdx,y)" have no effect as, I think it's just pointing to the (reiserfs)content drives and this GRUB2 tells me "unknown filesystem".I did try them all in vain, hoping that maybe I'd find a kernel somewhere.I used the "rescue" mode of the Ubuntu installer (the USB thumb drive) to get to a root prompt.From there, I mounted /dev/sdc2 (the "shifted" /dev/sdb2) onto /mnt, I mounted /dev/sdc1 (the "shifted" /dev/sdb1) onto /mnt/boot,and then I chroot'ed to /mnt.I edited /boot/grub/grub.cfg, editing every instance of "root=(hd2,1)" to the appropriate UUID for the "real" /dev/sdb1. Then I issued update-grub2.It refused to work giving me an banal "no such partition" error or something like that.
We originally had this server functioning by putting / and /boot on the SS SanDisk, which caused no problems during installation because /dev/sda doesn't get shifted.We then figured it was a good idea to put our OS files on something with failover capability. And that started us down this crappy "shifting drive letter" path.Can I control which drive letter the USB thumb drive gets assigned during the install process?If I could make it be /dev/sdc then I wouldn't be facing this problem.An alternate solution would be to know the cryptic GRUB2 commands that I can issue from the command prompt post-install, pre-reboot.But I'm wondering if that will ultimately work at all considering that GRUB2 couldn't see /dev/sdb at all.
I am new to Linux ,i did one project in windows which will block the thumb drive with respect to serial number(Device instance ID) of the device.i am planning to do the same project in Linux using c/c++.I am very new to Linux,there is no drive letter for thumb drives we insert into Linux OS.How to get Drive letter and how to get Device instance id of thumb drives please help me get some clues.please provide me any tutorial or any links .w if have any other clues to block devices with respect "block list" and "allow device list".if the serial number in block list it has to block if serial number in allow device list it has to allow thumb drive to access.

Nothing happens when ordinary users plug in a USB thumb drive or insert a CD into CDROM drive. Works fine for root. After root mounts the drives then all users can use them. How can I enable mounting/unmounting by all users?

I installed Redhat Enterprise 3 on one of my servers. In my haste I didn't properly partition both Hard Drives and only properly partitioned one of them. Thus now I have
/dev/sdb1 478711768 137858256 316536328 31% /
/dev/sda1 101089 15346 80524 17% /boot
Where /dev/sda1 is actually a 80 GB hard drive. Is there anyway I can safely and easily repartition the unpartitioned space without causing a huge mess? I have a very important Oracle database on /dev/sdb1 and thus I want to be able to back it up on the second disk. I can create a partition on that drive?
I've just installed UNR version of Ubuntu on one of my thumb drives and was wondering what I needed to do to for making it have persistent changes?

View 3 Replies View RelatedI am building a home server that will host a multitude of files; from mp3s to ebooks to FEA software and files. I don't know if RAID is the right thing for me. This server will have all the files that I have accumulated over the years and if the drive fails than I will be S.O.L. I have seen discussions where someone has RAID 1 setup but they don't have their drives internally (to the case), they bought 2 separate external hard drives with eSata to minimize an electrical failure to the drives. (I guess this is a good idea)I have also read about having one drive then using a second to rsync data every week. I planned on purchasing 2 enterprise hard drives of 500 MB to 1 GB but I don't have any experience with how I should handle my data
View 10 Replies View RelatedI have a new Giada cube with no hard drive, so my plan is to simply run a Linux/MythTV distro called MythDora from a Patriot 8GB USB stick (this Giada does not PXE boot). I am having trouble figuring out exactly how to make this work. Yesterday, although I have forgotten exactly how, I was able to put a MythDora Live image on the stick and boot up. I went through the initial setup, and then, when I was all done, I rebooted, and..it started all over again...as if I was doing it for the first time. So...What do I need to do to create a proper bootable USB stick?What ISO image should I use? The full DVD? Or the Live ISO? or the Network image?Do I need to partition the stick and load the O/S from one small partition, transferring the installation to another larger one?What utility should I use to create the bootable stick? unetbootin? or similar?Do I have to do anything special to make my O/S and configuration changes persistent on the USB stick?

Do I format it to FAT? Never done this before. Also, how do I enable it when I boot up? Do I have to make my computer to boot from the USB drive first in the BIOS settings or is there an easier way to do it (like clicking on an icon inside the USB virtual drive on the desktop).
Have not found this elsewhere so here goes.
I had a friend ask how he could do his electronic banking without a chance of any information being left on his computer once he is done.
I thought of a Ubuntu live CD but have seen the HD activity light flashing when using one. That leads me to believe that some kind of use is made of the HD and that makes a live CD questionable. He wants no information on the HD even in unassigned sectors.
Maybe, better yet would be a USB thumb drive that runs Ubuntu or another distribution that will not use the HD or even require that one be in the computer. A plus with a thumb drive would be that it would only be available on the computer when it is being used so it could contain passwords etc. Of course, it would have to be removed when not in use.
I want to put Ubuntu on my 16 gb USB thumb-drive so that I can use Ubuntu on any computer willing to boot from a USB drive (at my office, my wife's desktop, etc.) I cannot find how to do this. All my search attempts show me how to put an "install disk" onto the USB thumb-drive using the command: System -> Administration -> Startup Disk Creator
I tried the above. The first time I booted from the thumb-drive it asked me whether I wanted to try using Ubuntu from the thumb-drive or install. Having to make that selection with each boot would be a slight pain, but not a deal-breaker. But then the thumb-drive OS detected my laptop's wireless card, asked to install a driver, and then asked to reboot. Now it does some odd blended boot where it skips my hard drive's Grub Loader (so it *is* still booting off the thumb-drive) but goes to my hard drive's account sign-in. How can I make a USB thumb-drive that boots Ubuntu Desktop just as a normal hard drive, with accounts and the ability to install drivers and new software?
I tried to install ubuntu 10.04 to a 16 gig thumb drive and the installation went perfectly. However, when I removed the thumb drive and tried to boot the computer back into windows I saw that the installer had installed GRUB on to the hard drive of the computer. Windows runs fine, but it wont start with out the thumb drive that has the ubuntu install on it, this is very bad for me. Is there a way I can remove GRUB with out messing up windows on the computer? i dont have a windows 7 boot disk so this operation would need to be done either in windows (already booted) or ubuntu.
