  • Pen drive cannot be mounted

    - by DUKE
    I get the following message when I insert my pen drive to USB port. I am unable to format it as well. (This pen drive earlier used as a bootable drive for Ubuntu 12.04) I am using Ubuntu 12.04 LTS. lsusb command in the terminal gives the following message: siva@siva:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 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 001 Device 002: ID 0424:2513 Standard Microsystems Corp.

  • What is a dedicated Linux box used for?

    - by DanLeaningphp
    So this is probably a very basic and obvious question for most people, but my google-foo is failing me and it just seems something is going over my head. I've heard numerous people refer to having a 'dedicated linux box' as a central part of a developer's setup. I have been doing web-dev programming for about a year and understand the benefits of programming on a Unix/Linux system. But I seem to be missing what role a 'dedicated linux box' plays in the development process. I would assume that it is used as a server of some sort, but I am yet to run across any needs to have a computer dedicated to running a linux server. Am I just being nieve and mistaking the commonality of programmers preferring to work in linux for a tool used by developers? What do most developers use their 'dedicated linux box' for?

  • With a typical USB hard drive enclosure, is the full range of drive power management functionality available?

    - by intuited
    In what may be an unrelated matter: is it possible to suspend a PC without unmounting an attached USB-powered drive, and then remounting it on resume? This is the behaviour I'm currently seeing (running Ubuntu linux 10.10). Are there certain models or brands that provide more complete control over this aspect of drive operation? My Friendly Neighbourhood Computer Store carries (part of) the Vantec Nexstar product line.

  • linux/unix filesystem permissions hack/feature

    - by selden
    Can linux or other unix create a file that no user, including root, can modify unless they have the secret key? By "have the secret key" I mean they are using some crypto scheme. Here's a scenario if you aren't already downvoting: Bob encrypts something about file /foo (maybe inode?) using secret key K Alice tries "sudo rm /foo" and gets permission denied, so she decrypts something about file /foo using secret key K and then "sudo rm /foo" succeeds.

  • 'Unable to mount Filesystem' Error

    - by Charles
    Trying to extract data from a 'bricked' Western Digital MyBook Live 2tb drive. I came across a forum that advised to use Ubuntu (booted from a CD) on my Macbook. Managed to download and create a boot CD for Ubuntu (like this little operating system btw). Booted the machine with the CD and plugged the drive (which I had extracted from it's casing and placed into a external USB SATA case & plugged to the laptop). The drive is seen by Ubuntu but each time I click on the drive, it gives me the following error: Unable to mount 2.0 TB Filesystem Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error In some cases useful info is found in syslog -try dmesg | tail or so I am new to this and spent quite some time searching this site to see if I could find a solution to this problem without troubling anyone. I came up with a few that came close but some of the questioners mentioned that they had lost data...which scared me from going further. I need to basically extract 1 particular folder from the drive. If I can get to mount this volume 'sdb4', there is a folder called 'My_Work' which I need to back up. The rest I have/had a copy of. When I typed in dmesg | tail...I got several lines..but I think ones that are relevant are: [ 406.864677] EXT4-fs (sdb4): bad block size 65536 [ 429.098776] hfs: write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only [ 439.786365] hfs: write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only [ 445.982692] EXT4-fs (sdb4): bad block size 65536 [ 1565.841690] EXT4-fs (sdb4): bad block size 65536 I read somewhere to try/check 'sudo fdisk -l /dev/sdb4'. It gave me the following result: Disk /dev/sdb44: 1995.8 GB, 1995774623744 bytes 255 heads, 63 sectors/track, 242639 cylinders, total 3897997312 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdb4 doesn't contain a valid partition table This is where I reached and got frustrated and decided to try & get help on this without digging myself deeper into a hole! I understand that the answer may already be out there. If so, could someone please point me in the right direction. And if not, could someone please resolve (if possible) my situation!

  • "No caching mode page present" when USB flash disk attached

    - by evgeny9
    When attaching a USB flash disk (NTFS formatted) to a laptop with Ubuntu Server 12.04 on board, I get following messages: [ 3572.355603] sd 2:0:0:0: [sdb] No Caching mode page present [ 3572.355640] sd 2:0:0:0: [sdb] Assuming drive cache: write through [ 3572.361599] sd 2:0:0:0: [sdb] No Caching mode page present [ 3572.361636] sd 2:0:0:0: [sdb] Assuming drive cache: write through I get them right in the terminal, so that I should press Ctrl+C to proceed with working (entering commands). Is it normal or do I have to setup Caching mode somehow? Thank you.

  • Chrome browser full Kiosk mode in Linux (Puppy Linux)

    - by Brandon Ellis
    Let me just say thanks in advance. I am having issues getting google-chrome browser into full KIOSK MODE with no browser bar on a linux platform Looking through the google forums I have found numerous postings on how to get Chrome to show full kiosk mode BUT tried to execute with --kiosk but doesnt seem to get the job done. I dont know if this is platform specific or not, but any useful information would help. I know F11 will display the browser in full kiosk mode, with no browser bar BUT is there a way to do this with a linux script and no need for a monkey pressing F11??

  • Run one virtual machine on a Linux server + standard Linux functions

    - by fistameeny
    Hi, I am looking for a method to setup a Linux server (running Ubuntu Server) that uses Samba for file sharing, as well as hosting a Windows virtual machine (in this case, Windows Small Business Server 2003, which in turn hosts SQL Server Express - Exchange won't be used on this). I would like to have the Linux server serving the files over Samba, and hosting the Virtual Machine. This obviously rules ESXi out as it couldn't do Samba at the same time. What would be the next best solution to give reasonable speed? Vmware Server 2.0, VirtualBox, Xen? There will be 10-15 users accessing the Samba shares and the SQL Express virtual machine. Matt

  • Conditional dev|nfs mount in Linux

    - by o_O Tync
    I have a mount point — let it be /media/question — and two possible devices: a physical HDD and a remote NFS folder. Sometimes I plug the device in physically, in other cases I mount it via NFS. Is there a way to specify both of them in fstab so that executing mount /media/question will preferably choose physical volume, and when it's not available — NFS?

  • HP DL380 G5 Predictive Drive Failure on a new drive

    - by CharlieJ
    Consolidated Error Report: Controller: Smart Array P400 in slot 3 Device: Physical Drive 1I:1:1 Message: Predictive failure. We have an HP DL380 G5 server with two 72GB 15k SAS drives configured in RAID1. A couple weeks ago, the server reported a drive failure on Drive 1. We replaced the drive with a brand new HDD -- same spares number. A few days ago, the server started reporting a predictive drive failure on the new drive, in the same bay. Is it likely the new drive is bad... or more likely we have a bay failure problem? This is a production server, so any advice would be appreciated. I have another spare drive, so I can hot swap it if this is a fluke and new drive is just bad. THANKS! CharlieJ

  • CPU and HD degradation on sourced based Linux distribution

    - by danilo2
    I was wondering for a long time if source based Linux distributions, like Gentoo or Funtoo are "destroying" your system faster than binary ones (like Fedora or Debian). I'm talking about CPU and hard drive degradation. Of course, when you're updating your system, it has to compile everything from source, so it takes longer and your CPU is used at hard conditions (it is warmer and more loaded). Such systems compile hundreds of packages weekly, so does it really matter? Does such a system degrade faster than binary based ones?

  • OS X Hard drive recovery

    - by Adam
    I am trying to recover data from a bad Seagate 1TB hard drive in a 2010 iMac. One day the iMac wouldn't boot (stuck at gray screen on startup). I removed the hard drive from the iMac and connected it to a MacBook using a 3.5" HDD to USB adapter. The hard drive wouldn't mount but it did display in Disk Utility that that there were 2 partitions on the disk. I tried to run Disk Warrior and it showed thousands of errors but still wouldn't mount. At this time the hard drive only show one partition in Disk Utility. Next I tried putting the hard drive in a desktop PC and running Spin Rite - which then gave me several division overflow errors (even with running Spin Rite with a newer version of DOS). The SMART status on the drive reports that the drive has had failures and HD Tune referenced the drive had once hit 59 degrees celsius. Disk Utility gives me the following message when running a pair: Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. Overall, the hard drive spins up and sounds OK - there are no clicking noises but the hard drive won't mount and displays as a light gray "Macintosh HD" in disk utility. Any tips or advice on how to recover data on this drive would be GREATLY appreciated! Are there any other tools I can try before calling it quits on this drive? Thank you

  • PC won't boot from IDE HDD when SATA data drive connected

    - by Kevin
    I have an old Pentium 4 system running XP. The machine is set up as an HTPC. It was set up and running well with 1 SATA drive as a boot drive, another SATA drive to store TV recordings, and an IDE drive to store more recordings. Last week the original boot drive (a SATA drive) failed. The BIOS would no longer recognize it. I had a disused IDE drive hanging around that was large enough for the OS, so I reformatted it and installed XP on it. Now the system will only boot if I do not connect the remaining healthy SATA data drive. All three drives are recognized by the BIOS, and I have set the boot order so that the IDE drive with XP on it has top priority, but after the BIOS recognizes the drives, etc. I just get a black screen. I know the SATA drive is functional, because if I hot plug the drive AFTER the system is booted (I know I'm not supposed to do this), I can go into the control panels and mount the drive, and see all the files and folders on it in Windows Explorer. Any suggestions on what is going on and how to fix it? Many thanks.

  • CD Drive not discovered

    - by user1009073
    I have a self built computer. it uses a P6T Deluxe motherboard, which has both SATA and IDE ports. This was built several years ago, and had an IDE CD/DVD drive. This drive started going bad (would not burn CDs correctly), so I decided to replace it. I had difficultly finding an IDE DVD drive, so I bought a SATA DVD drive. I opened the comnputer, took out the old DVD drive. I left the IDE cable in place, connected to the motherboard, but it is not connected to any drives. I hooked up the new DVD drive, both power and with a SATA data cable (SATA port 3 if I recall). (Sony Optiarc 24x , Newegg URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16827118067 ) When I power on my computer, the drive does NOT show up in Explorer. I can hit the DVD eject button, and the drive will open up, so I know it at least is getting power. I thought, maybe something in the BIOS. When I go to BIOS, boot devices, it shows (1) floppy, (2) my hard drive (3) ATAPI CD Drive. The only other possible BIOS option I could find was uder 'Storage Configuration'. Configure Storage as: My setting is RAID, since I am using two drives in a RAID configuration. Other options were IDE and ACHI. Other than trying to find an IDE DVD drive, is there anything else I can try? The drive does not show up at all in Windows Explorer. I did put in a CD thinking that might help, but nothing happened. Thanks, GS

  • Boot problems w/ External HDD

    - by JeremyT
    I'm having a problem with booting a live image off of a USB Hard Drive. I used Startup Disk Creator to make an Ubuntu 11.10 live image on a partition on my external so that I can use it on various computers. I set it up with ~4GB of persistent data So far I've tried it on two computers. One, a Dell, will boot to my external but it loads the select boot device very slowly. It hangs on a screen with an underscore for up to 5 minutes until it allows me to select which drive I want to boot from. After that, it works great. However, on my primary computer it doesn't work at all. It's an Acer from 2009 and it won't even recognize the drive. I don't see it anywhere in BIOS or the select boot disk list. The light on the external will come on at boot just fine so I know it's powering it at this time. Both computers worked perfectly with my 4GB flash drive that I had partitioned half and half (1st half FAT32 and second Ubuntu 11.10 live)

  • How to create NTFS partition in Linux to install Windows 7 from USB?

    - by Michal Stefanow
    I messed up with my computer and need help. Generally: install Windows 7 from USB. Problem: "setup was unable to create a new system partition" When first attempt to install Windows 7 failed I tried Linux live USB, installed distro to HDD, and erased all the existing partitions. Current state (fdisk -l): [writing from other computer so no copy and paste] /dev/sda1 305GB Linux /dev/sda2 7GB Extended /dev/sda5 7GB Linux Swam / Solaris To create a new, NTFS partition: fdisk /dev/sda n (for new) p (for primary) 3 (for partintion number) "No free sectors available" All the HDD was formatted couple of minutes before so there is a lot of free space but how to resize a parition? I cannot find an option for resizing in man fdisk. Some people say I should use gparted but my distro doesn't not contain this package. And my distro doesn't support wireless drivers so I have serious problems with downloading stuff. I tried also using cfdisk but any command results in: "cfdisk bad primary partition 1 partition ends in the final partial cylinder" I tried also removing partition 1 and then creating a new one (so there is no "no free sectors"). I'm receiving a warning: "Re-reading the partition table failed with error 16: Device or resource busy. The kernel still uses the old table. The new table will be used at the next reboot." After restating: "grub rescue, no known filesystem" It may indicate that some changes have been made BUT when running Windows 7 installed some another error: "Windows cannot be installed to Disk 0 Partition 1" More detailed: "Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS." So formatting drive using Windows 7 installer BUT this time yet another error: "Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information" Apparently I cannot access logs (how?) and I am back to drawing board with my live USB (this time showing partition as HPFS/NTFS). Any suggestions how to install Windows 7? Should I reinstall Linux to HDD, erase existing partitions once again, and use Parted rather than gparted (parted is included in the distro). Or maybe should I create another bootable USB such as PartedMagic to painlessly create partitions? I just want to install Windows 7 from USB, my laptop is semi-operational and I am ready to receive some help regarding fdisk and creating NTFS partitions. UPDATE: I did as suggested (removed all the partitions) and tried to install in unallocated space. Tried to create a new partition and format it. Same error: "setup was unable to create a new system partition" Came to the conclusion it may have something to do with TrueCrypt I have recently installed. Right now trying to FIX MBR (as I haven't got possibility to create rescue disc without optical drive)
