  • Ubuntu 12.10 install stuck at first step

    - by Josh Clarke
    I'm trying to install Ubuntu 12.10 from a DVD-R disk, and everything is just fine until I get to the first window after clicking "Install Ubuntu" I checked the box "Download updates while installing" and also the "Install third-party software" box. After clicking next, however, the install just hangs there. I've been waiting for over an hour now and all I see is the mouse cursor showing that it's "loading". What should I do to get past this? Thanks!

  • External hard drive not recognized

    - by sr71
    Installed Ubuntu 10.10 on a hard drive by itself (no windows). All updates are up to date. Everything`works fine except when I plug in a 320 gig Toshiba external hard drive....it is not recognized. When I plug in an 8 gig flash drive it is recognized no problem. What do I mean by "not recognized"? I mean: how do you know it was not recognized. You can check the command "cat /proc/partitions" in a terminal with and without the hdd attached. If you see some difference, it's ok. If the difference is something like "sda1" (sd+letter+number) then you have partition on it, maybe it can't be handled in Ubuntu (no filesystem on it or so). If there is only "sda" in the difference for example (sd+letter, but no number after it) then the drive itself is detected, just no partition is created on it. Also you can check out the messages of the kernel, with the "dmesg" command in the terminal. If there is no disk/partition/anything in /proc/partitions, there can be an USB level problem, you can issue command "lsusb" as it was suggested before my answer. It's really matter of what do you mean about "not recognized". @Marco Ceppi @Oli @Pitto By "not recognized" I meant that when I plug in a 8 gig flash drive an icon immediately appears on the desktop imdicating that there is a flash drive plugged in and I can click on it and view the files on the flash drive. It also shows up on the "Nautilus" default file manager. When I plug in the 320 gig Toshiba external hard drive, I get no indication on the desktop or the file manager (thus "not recogized"). When I run the command cat/proc/partitions/ I get an error message Could not open location 'file:///home/bob/cat/proc/partitions' with or without the external hard drive installed. With the dmeg command I get about 10 pages of info with no mention of disk/partition/anything in /proc/partitions. When I run lsusb command I get the following: bob@bob-desktop:~$ lsusb Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 003: ID 04b3:3003 IBM Corp.

  • udev hide partition in nautilus for specific user/group

    - by user64780
    I'm trying to hide a partition form a specific group of users in Ubuntu 12.04. I have created a new rule in /etc/udev/rules.d/99-hide-disk.rules with KERNEL="sda3",ENV{UDISKS_PRESENTATION_HIDE}="1" And this works for all users. I tried KERNEL="sda3",ENV{UDISKS_PRESENTATION_HIDE}="1",GROUP="adm",MODE:="0700 but the partition is still hidden. That changes the group and permissions on the device rather than the rule. How do I make the rule only apply to a particular group of users?

  • Hybrid Graphics on Ubuntu 12.04 switching to discrete

    - by cfstras
    I have a Sony Vaio VPCCB-27FX with hybrid graphics. Using vgaswitcheroo enables me to switch my discrete card off to save power. Now when i want to switch to the discrete card for performance, my system freezes. I already tried logging out and killing x with service lightdm stop, but still, it freezes as soon as I echo DIS > switch. typing blindly, echo IGD > switch returns me to my console where it reads [ 179.555171] i915: switched off, but it seems the discrete card never gets switched on... running echo DDIS > switch gives me the following: [540....] [drm:atop_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [540....] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing CEE2 (len 62, WS 0, PS 0) @ 0xCEFE [540....] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing BBF6 (len 1036, WS 4, PS 0) @ 0xBCF3 [540....] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing BB8C (len 76, WS 0, PS 0) @ 0xBB94 [541....] [drm:r600_RING_TEST] *ERROR* radeon: ring test failed (scratch(0x8504)=0xFFFFFFFF) [541....] [drm:evergreen_resume] *ERROR* evergreen startup failed on resume after that, the atombios part repeats a few times. also, the terminal locks up again and sysrq+REISUB is my only rescue.

  • Ubuntu doesn't boot due to GRUB-Problems

    - by Dave
    Users out there, I came here with the spark of a hope, that you could help me. I want to get rid of my old WinXP, because the Game-Support for it seems to slowly expire now... So I took a second drive, just an old empty one I had at hands (ATA-Maxtor 90648D3), plugged of the other drive with WinXP, so that it couldn't be harmed, and started the installationof Ubuntu 12.04. Everything went as it was supposed to, until the end. Normal shutdown after successful installation process. But when I tried to boot my new Ubuntu from the HDD, it said: error: out of disk. grub rescue> So, what to do now? I already tried a lot of things in the terminal, e.g. the update-grub as mentioned on http://opensource-sidh.blogspot.de/2011/06/recover-grub-live-ubuntu-cd-pendrive.html. Everything worked, he didn't complain about a missing data or anything, but at the end of the day he still wasn't able to boot! Next step was to change the etc/default/grub-file, so that it could load the ATA-drivers first, so that there is now problem with my drive. But even this didn't seem to have any effect, I'm still stuck with Ubuntu in the Live-CD-Mode... If there was anybody to help me out there, I would be very glad. Thanks for any support, Dave P.S.: I even tried to fix it with boot-repair, a small tool for Ubuntu, and it created a file with data that could probably help you to help me. You can find it on http://paste.ubuntu.com/1428022/

  • How to repair unbootable Fedora install

    - by Cerin
    How do you repair/reinstall Fedora without deleting any existing partitions or data? I was attempting to upgrade some old Fedora 13 servers to 17, following the instructions in the wiki. After the 14-15 upgrade, rebooting resulted in the output: Dropping to debug shell. sh: can't access tty; job control turned off dracut:/# Running dmesg also shows: dracut Warning: No root device "block:/dev/mapper/VolGroup-lv_root" found Googling shows this error is typically related to some weird RAID issues, but my server is a virtual machine not using any RAID. Using a rescue CD, I can chroot /mnt/sysimage, and all packages and data still seems to be there. How do I make the system bootable again?

  • How do I duplicate a server's packages and configuration to another machine?

    - by sharjeel
    I have a production server running Ubuntu. I would like to setup similar configuration installed on my local machine. I'd like to have same packages installed. Since bandwidth is a constraint the traditional disk cloning methods won't work for me. Having same packages installed and same users with same passwords created would be wonderful; i'll tweak rest of the things manually. Is there a good solution to my requirements?

  • Exploring In-memory OLTP Engine (Hekaton) in SQL Server 2014 CTP1

    The continuing drop in the price of memory has made fast in-memory OLTP increasingly viable. SQL Server 2014 allows you to migrate the most-used tables in an existing database to memory-optimised 'Hekaton' technology, but how you balance between disk tables and in-memory tables for optimum performance requires judgement and experiment. What is this technology, and how can you exploit it? Rob Garrison explains.

  • I Clobbered a Leopard with a Window Last Night

    - by D'Arcy Lussier
    I’ve had my 15” Mac Book Pro for a little over a year now, and its hands-down the best laptop I’ve ever owned…hardware wise. And I tried, I really really tried, to like OSX. I even bought Parallels so I could run Windows 7 and all my development tools while still trying to live in an OSX world. But in the end, I missed Windows too much. There were just too many shortcomings with OSX that kept me from being productive. For one thing, Office for Mac is *not* Office for Windows. The applications are written by different teams, and Excel on the Mac is just different enough to be painful. The VM experience was adequate, but my MBP would heat up like crazy when running it and the experience trying to get Windows apps to interact with an OSX file system was awkward. And I found I was in the VM more than I thought I’d be. iMovie is not as easy to use for doing simple movie editing as Windows Movie Maker. There’s no free blog editing software for OSX that’s on par with Windows Live Writer. And really, all I was using OSX for was Twitter (which I can use a Windows client for) and web browsing (also something Windows can provide obviously). So I had to ask myself – why am I forcing myself to use an operating system I don’t like, on a laptop that can support Windows 7? And so I paved my MBP and am happily running Windows 7 on it…and its fantastic! All the good stuff with the hardware is still there with the goodness of Win 7. Happy happy. I did run into some snags doing this though, and that’s really what this blog post is about – things to be aware of if you want to install Win 7 directly on your MBP metal. First, Ensure You Have Your Original Mac Install Disk This was a warning my buddy Dylan, who’s been running Win 7 on his MBP for a while now, gave me early on. The reason you need that original disk is that the hardware drivers you need are all located there. Apparently you can’t easily download them, so make sure you have them ahead of time. Second, Forget BootCamp The only reason you need BootCamp is if you still want the option to boot into OSX. If you don’t, then you don’t need BootCamp. In fact, you don’t even need BootCamp to install Win 7. What you *will* need though is a DVD with Win 7 burnt on it. Apple doesn’t support bootable USB drives. Well, actually they do for Mac Book Airs which don’t come with optical drives…but to get it working you’ll need to edit a system file of BootCamp so your make of MBP is included in an XML document, and even then you *still* are using BootCamp meaning you’ll be making an OSX partition. So don’t worry about BootCamp, just burn a Windows 7 disc, put it into the DVD drive, and restart your MBP. Third, Know The Secret Commands So after putting in the Windows 7 DVD and restarting your MBP, you’ll want to hold down the ‘C’ key during boot up. This tells the MBP that it should boot from the DVD drive instead of the hard drive. Interestingly, it appears you don’t have to do this if its the Mac OSX install disc (more on that in a second), but regardless – hold down C and Windows will start the install process. Next up is the partition process. You’ll notice that there’s a partition called ETI or something like that. This has to do with the drive format that Apple uses and how they partition their system drives. What I did – I blew it away! At first I didn’t, but I was told I couldn’t install Windows on the remaining space due to the different drive format. Blowing away the ETI partition (and all other partitions) allowed me to continue the Windows install. *REMEMBER –  No warranty is provided or implied, just telling you what I did and how I got it to work. Ok, so now Windows is installed and I’m rebooting. Everything looks good, but I need drivers! So I put in the OSX install DVD and run the BootCamp assistant which installs all the Windows drivers I need. Fantastic! Oh, I need to restart – no problem. OH NO, PROBLEM! I left the OSX install DVD in the drive and now the MBP wants to boot from the drive and install OSX! I’m not holding down the C key, what the heck?! Ok, well there must be a way to eject this disk…hmm…no physical button on the side…the eject button doesn’t seem to work on the keyboard…no little pin hole to insert something to force the disc out…well what the…?! It turns out, if you want to eject a disc at boot up, you need (and I kid you not) to plug a mouse into the laptop and hold down the right-click button while its booting. This ejected the disc for me. Seriously. Finally, Things You Should Be Aware Of Once you have Windows up and running there’s a few things you need to be aware of, mainly new keyboard shortcuts. For instance, on the Mac keyboard there is no Home, End, PageUp or PageDown. There’s also no obvious way to do something like select large amounts of text (like you would by holding Shift-Home at the end of a line of text for instance). So here’s some shortcuts you need to know: Home – fn + left arrow End – fn + right arrow Select a line of text as you would with the Home key – Shift + fn + left arrow Select a line of text as you would with the End key – Shift + fn + right arrow Page Up – fn + up arrow Page Down – fn + down arrow Also, you’ll notice that the awesome Mac track pad doesn’t respond to taps as clicks. No fear, this is just a setting that needs to be altered in the BootCamp control panel (that controls the Mac Hardware-specific settings within Windows, you can access it easily from the system tray icon) One other thing, battery life seems a bit lower than with OSX, but then again I’m also doing more than Twitter or web browsing on this thing now. Conclusion My laptop runs awesome now that I have Windows 7 on there. It’s obviously up to individual taste, but for me I just didn’t see benefits to living in an OSX world when everything I needed lived in Windows. And also, I finally am back to an operating system that doesn’t require me to eject a USB drive before physically removing it! It’s 2012 folks, how has this not been fixed?! D

  • "Verifying DMI Pool" hang caused by raid array..

    - by Ling
    Hi Experts, I have a problem, I obtained a new server with 4 hard drives (2 500 gig, 2 two TB), and an adeptec RAID card. I arranged them in two arrays with RAID 1 (500 gigs together as primary and the 2 TB drives for lots of data). When both arrays are configured, the server hangs while booting at message "Verifying DMI Pool", however if I remove the second array from the configuration the server boots fine. I have checked they are both on different channels, I have disabled all other peripherals from the boot menu and ensured the hard drive is #1. I have booted into the linux rescue mode and checked that it is reading both arrays fine. What else could be causing these problems? Thanks

  • Install GRUB to Ubuntu Partition

    - by Noel
    So my computer has the following partitions: /dev/sda -- (I know this isn't a real partition, but more so the boot loader) /dev/sda1 -- (Windows 7 Boot Loader) /dev/sda3 -- (Windows 7) /dev/sda4 -- (Data partition, NTFS) that means i have /dev/sda2 as free space. I do not want to change the MBR of the computer. I would like /dev/sda2 to contain GRUB AND Ubuntu. So ideally when I turn my computer on, BIOS would ask if I'd like to boot Windows 7 or Ubuntu(or Grub or partition 2), and I could choose either one. But I would like Grub and Ubuntu to be on the same partition, so they will not interfere in any way with windows or window's boot loader/partition (sda3) How can I do this? Catch: when formatting partitions, Ubuntu does not give me the option to make them virtual partitions, so that makes things harder. I tried: installing Ubuntu to /dev/sda2 (which I formatted as ext4) and then told the Ubuntu installer to install the bootloader to /dev/sda2. But when I select "Ubuntu" from BIOS's boot selection, it loads a black screen and says "invalid arch independent ELF magic grub rescue _" and allows me to input stuff. How can I fix this, or tell my computer where Grub is?

  • How to Generate a Create Table DDL Script Along With Its Related Tables

    - by Compudicted
    Have you ever wondered when creating table diagrams in SQL Server Management Studio (SSMS) how slickly you can add related tables to it by just right-clicking on the interesting table name? Have you also ever needed to script those related tables including the master one? And you discovered you have dozens of related tables? Or may be no SSMS at your disposal? That was me one day. Well, creativity to the rescue! I Binged and Googled around until I found more or less what I wanted, but it was all involving T-SQL, yeah, a long and convoluted CROSS APPLYs, then I saw a PowerShell solution that I quickly adopted to my needs (I am not referencing any particular author because it was a mashup): 1: ########################################################################################################### 2: # Created by: Arthur Zubarev on Oct 14, 2012 # 3: # Synopsys: Generate file containing the root table CREATE (DDL) script along with all its related tables # 4: ########################################################################################################### 5:   6: [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null 7:   8: $RootTableName = "TableName" # The table name, no schema name needed 9:   10: $srv = new-Object Microsoft.SqlServer.Management.Smo.Server("TargetSQLServerName") 11: $conContext = $srv.ConnectionContext 12: $conContext.LoginSecure = $True 13: # In case the integrated security is not used uncomment below 14: #$conContext.Login = "sa" 15: #$conContext.Password = "sapassword" 16: $db = New-Object Microsoft.SqlServer.Management.Smo.Database 17: $db = $srv.Databases.Item("TargetDatabase") 18:   19: $scrp = New-Object Microsoft.SqlServer.Management.Smo.Scripter($srv) 20: $scrp.Options.NoFileGroup = $True 21: $scrp.Options.AppendToFile = $False 22: $scrp.Options.ClusteredIndexes = $False 23: $scrp.Options.DriAll = $False 24: $scrp.Options.ScriptDrops = $False 25: $scrp.Options.IncludeHeaders = $True 26: $scrp.Options.ToFileOnly = $True 27: $scrp.Options.Indexes = $False 28: $scrp.Options.WithDependencies = $True 29: $scrp.Options.FileName = 'C:\TEMP\TargetFileName.SQL' 30:   31: $smoObjects = New-Object Microsoft.SqlServer.Management.Smo.UrnCollection 32: Foreach ($tb in $db.Tables) 33: { 34: Write-Host -foregroundcolor yellow "Table name being processed" $tb.Name 35: 36: If ($tb.IsSystemObject -eq $FALSE -and $tb.Name -eq $RootTableName) # feel free to customize the selection condition 37: { 38: Write-Host -foregroundcolor magenta $tb.Name "table and its related tables added to be scripted." 39: $smoObjects.Add($tb.Urn) 40: } 41: } 42:   43: # The actual act of scripting 44: $sc = $scrp.Script($smoObjects) 45:   46: Write-host -foregroundcolor green $RootTableName "and its related tables have been scripted to the target file."

  • Reading a ZFS USB drive with Mac OS X Mountain Lion

    - by Karim Berrah
    The problem: I'm using a MacBook, mainly with Solaris 11, but something with Mac OS X (ML). The only missing thing is that Mac OS X can't read my external ZFS based USB drive, where I store all my data. So, I decided to look for a solution. Possible solution: I decided to use VirtualBox with a Solaris 11 VM as a passthrough to my data. Here are the required steps: Installing a Solaris 11 VM Install VirtualBox on your Mac OS X, add the extension pack (needed for USB) Plug your ZFS based USB drive on your Mac, ignore it when asked to initialize it. Create a VM for Solaris (bridged network), and before installing it, create a USB filter (in the settings of your Vbox VM, go to Ports, then USB, then add a new USB filter from the attached device "grey usb-connector logo with green plus sign")  Install a Solaris 11 VM, boot it, and install the Guest addition check with "ifconfg -a" the IP address of your Solaris VM Creating a path to your ZFS USB drive In MacOS X, use the "Disk Utility" to unmount the USB attached drive, and unplug the USB device. Switch back to VirtualBox, select the top of the window where your Solaris 11 is running plug your ZFS USB drive, select "ignore" if Mac OS invite you to initialize the disk In the VirtualBox VM menu, go to "Devices" then "USB Devices" and select from the dropping menu your "USB device" Connection your Solaris VM to the USB drive Inside Solaris, you might now check that your device is accessible by using the "format" cli command If not, repeat previous steps Now, with root privilege, force a zpool import -f myusbdevicepoolname because this pool was created on another system check that you see your new pool with "zpool status" share your pool with NFS: share -F NFS /myusbdevicepoolname Accessing the USB ZFS drive from Mac OS X This is the easiest step: access an NFS share from mac OS Create a "ZFSdrive" folder on your MacOS desktop from a terminal under mac OS: mount -t nfs IPadressofMySoalrisVM:/myusbdevicepoolname  /Users/yourusername/Desktop/ZFSdrive et voila ! you might access your data, on a ZFS USB drive, directly from your Mountain Lion Desktop. You might play with the share rights in order to alter any read/write rights as needed. You might activate compression, encryption inside the Solaris 11 VM ...

  • Safety of installing Ubuntu alongside Windows

    - by giowck
    Is it really safe to chose the "Install Ubuntu alongside Windows" option from the Ubuntu installation program? I never used that option, instead I used other tools such as partition magic or windows 7's disk tool to resize my partitions. Since I'm going to install Ubuntu across a lot windows (XP, Vista and 7) machines. It would not be nice to damage those Windows partitions. What is your experience? Can I use this feature without concerns?

  • A Star Path finding endless loop

    - by PoeHaH
    I have implemented A* algorithm. Sometimes it works, sometimes it doesn't, and it goes through an endless loop. After days of debugging and googling, I hope you can come to the rescue. This is my code: The algorythm: public ArrayList<Coordinate> findClosestPathTo(Coordinate start, Coordinate goal) { ArrayList<Coordinate> closed = new ArrayList<Coordinate>(); ArrayList<Coordinate> open = new ArrayList<Coordinate>(); ArrayList<Coordinate> travelpath = new ArrayList<Coordinate>(); open.add(start); while(open.size()>0) { Coordinate current = searchCoordinateWithLowestF(open); if(current.equals(goal)) { return travelpath; } travelpath.add(current); open.remove(current); closed.add(current); ArrayList<Coordinate> neighbors = current.calculateCoordAdjacencies(true, rowbound, colbound); for(Coordinate n:neighbors) { if(closed.contains(n) || map.isWalkeable(n)) { continue; } int gScore = current.getGvalue() + 1; boolean gScoreIsBest = false; if(!open.contains(n)) { gScoreIsBest = true; n.setHvalue(manhattanHeuristic(n,goal)); open.add(n); } else { if(gScore<n.getGvalue()) { gScoreIsBest = true; } } if(gScoreIsBest) { n.setGvalue(gScore); n.setFvalue(n.getGvalue()+n.getHvalue()); } } } return null; } What I have found out is that it always fails whenever there's an obstacle in the path. If I'm running it on 'open terrain', it seems to work. It seems to be affected by this part: || map.isWalkeable(n) Though, the isWalkeable function seems to work fine. If additional code is needed, I will provide it. Your help is greatly appreciated, Thanks :)

  • Looking for an ultra portable laptop for Ubuntu

    - by prule
    Hi, I'm in the market for a new laptop, and portability is important since I really only use it when I'm travelling to and from work - primarily for programming. I've been searching high and low for something like this: less than 2kg hopefully Intel i5 (but negotiable) NO dvd drive - just don't need it 4G ram either 7200rpm disk or SSD (ssd preferable) 13 inch screen not too pricey (MacBook Air is about $1700 AUD) available in Australia The Dell Inspiron 13z and Lenovo Edge 13 look close, but I've not found anything that says I'm not going to have a fight with compatibility. The MacBook Air 13 looks like the PERFECT hardware, but I'm afraid it will just be easier to run MacOS than Ubuntu. I want to stay with Ubuntu, but the MacBook Air is only $1700 so I'm in danger of becoming another apple fanboi if I can't find anything competitive. Going through all the sites looking for stuff has been a huge waste of time System 76 doesn't deliver to Australia http://www.linux-laptop.net/ and http://www.linlap.com/ are hard work and not confidence inspiring http://www.vgcomputing.com.au/nsintro.html is hard work again, searching for every laptop they say has excellent compatibility on the web to find out what spec it is http://zareason.com/shop/Strata-Pro-13.html (at $1345 USD) looks interesting, but I've got no idea how much I'll get stung by customs importing Dell Inspiron 13z with i5, 4G, 320 7200rpm disk, ATI Mobility Radeon HD5430 - 1GB, Dell Wireless 1501 802.11b/g/n @ $1200 AUD seems like the only competitor but is it compatible? (Dell support offer no opinion - as far as they are concerned they only have 2 models that are certified for ubuntu) Am I worrying too much about the compatibility? Should I just go with Dell? Or switch to MacOS? (It would be good to have a searchable database that had the full machine specs, and compatibility - I'm thinking about building something... but I don't have much time right now...) Thanks. UPDATE I went with a MacBook Air. The price/weight/power was just right. Everything else was either too pricy (i5) or too heavy, or underpowered (SU7300 1.3GHz). Its a pity, because I didn't really want to leave Ubuntu. I'll still run it on my media center and spare (heavy) laptop.

  • Trying to recover deleted Ubuntu partition

    - by user110984
    I made a mistake in logging into my 200 GB Ubuntu partition. I could not access Grub after that. Using a live CD I then ran Boot_Repair and apparently deleted the partition, I guess because I ran it from my 70 GB Windows partition. I can send the results of boot_info before that and of Boot_Repair. Then I ran TestDisk, which apparently found only dev/sda/ -320GB / 298 / GiB - WDC - WD3200BEVT-22A23T0 (Was there any more I could have done with TestDisk? I looked at the TestDisk_Step_By_Step example and found no way forward given that no other partitions turned up) I have run gpart and found this: /sda1 - 15 GB /sda2 - system reserved /sda3 - 70.15 GB /sda4 - extended 212.84 unallocated - 209.10 /sda5 - unknown 3.74 . I have been told I can recover the partition using gparted's Rescue start end command, but I don't know what to enter for start and end. [--EDIT: TestDisk Deeper Search stated that "the following partitions can't be recovered" and listed a 220-GB Linux partition 6 times. Then it stated that "The current number of heads per cylinder is 255 but the correct value may be 128" and I could try to change it in the Geometry menu (because apparently these are overlapping partitions) So should I do that?--]

  • Ubuntu 10.10 not recognizing external hard drive

    - by sr71
    Installed Ubuntu 10.10 on a hard drive by itself (no windows). All updates are up to date. Everything`works fine except when I plug in a 320 gig Toshiba external hard drive....it is not recognized. When I plug in an 8 gig flash drive it is recognized no problem. What do I mean by "not recognized"? I mean: how do you know it was not recognized. You can check the command "cat /proc/partitions" in a terminal with and without the hdd attached. If you see some difference, it's ok. If the difference is something like "sda1" (sd+letter+number) then you have partition on it, maybe it can't be handled in Ubuntu (no filesystem on it or so). If there is only "sda" in the difference for example (sd+letter, but no number after it) then the drive itself is detected, just no partition is created on it. Also you can check out the messages of the kernel, with the "dmesg" command in the terminal. If there is no disk/partition/anything in /proc/partitions, there can be an USB level problem, you can issue command "lsusb" as it was suggested before my answer. It's really matter of what do you mean about "not recognized". @Marco Ceppi @Oli @Pitto By "not recognized" I meant that when I plug in a 8 gig flash drive an icon immediately appears on the desktop imdicating that there is a flash drive plugged in and I can click on it and view the files on the flash drive. It also shows up on the "Nautilus" default file manager. When I plug in the 320 gig Toshiba external hard drive, I get no indication on the desktop or the file manager (thus "not recogized"). When I run the command "cat/proc/partitions/" I get an error message Could not open location 'file:///home/bob/cat/proc/partitions' with or without the external hard drive installed. With the "dmeg" command I get about 10 pages of info with no mention of disk/partition/anything in /proc/partitions. When I run "lsub" command I get the following: bob@bob-desktop:~$ lsusb Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 003: ID 04b3:3003 IBM Corp.
