  • "A disk read error occurred" when booting XP disk image in VirtualBox

    - by intuited
    I'm trying to boot an XP installation cloned into VirtualBox from a real drive. I'm getting the message A disk read error occurred Press Ctrl+Alt+Del to restart whenever* I try to boot the machine. * This is not strictly true: with AMD-V enabled, the boot process appears to not make it this far and instead hangs at a black screen with cursor. I created the VirtualBox image from the original drive using the following method: $ sudo ddrescue -n /dev/sdd sdd.img logfile # completed without errors $ VBoxManage convertfromraw sdd.img disk.vdi The original disk (and the image) contain a single NTFS partition with XP installed on it. The owner of the drive indicates that it did boot okay the last time the system made it that far. The (Pentium 4) system has a broken (enormous) heat sink, so at some point it failed to boot because it would quickly overheat and shut down. If I boot the VM from a live cd, I am able to mount its /dev/sda1 without any problems. I ran ntfsfix and didn't have any luck. I've read through the instructions on doing this. I didn't really follow them. For example, I didn't run MergeIDE before imaging because the machine was not bootable. However, the symptom of that problem seems to be quite different. The emitted message is contained in the volume boot record of the XP partition, which leads me to suspect that this is a problem with the core operating system bootstrap procedure, and not related to anything in the registry. I don't have an XP boot CD.

  • sudo apt-get moo and other easter eggs in Linux

    - by Arkapravo
    I came across this command while dabbling in Ubuntu 9.10: sudo get-apt moo acer@acer:~$ sudo apt-get moo (__) (oo) /------\/ / | || * /\---/\ ~~ ~~ ...."Have you mooed today?"... Which most surprisingly "made a MOO". (How unfortunate for the cows). Does anyone else know of funny command line easter eggs in their flavour of Linux (Fedora, Slackwire, Mandriva, Solaris, Suse, etc)?

  • Why Office 2007 override Windows regional date setting?

    - by Istari
    I have a problem with a specific user's computer running windows XP SP2 and Office 2007. Although she has the regional date setting in windows to dd/mm/yyyy, her office applications are still reverting to mm/dd/yyyy which is driving her (and me) nuts. None of our other machines is doing this. Does anyone have a clue as to what to be looking for as the source of this irritating problem?

  • Setting up a wireless connection

    - by shadeMe
    I've got a DLINK router connected to my ADSL modem that forms the hub of my home network. I've two clients - A desktop with an onboard wireless adaptor and a laptop that's outfitted with the same. The former runs Windows 7 x64, the latter Windows XP x86. I'd like to setup a wireless connection between the two that would allow me play games over to and to a lesser extent, transfer and stream data. How would I go about doing it ?

  • Torrents: Can I protect my software by sending wrong bytes?

    - by martijn-courteaux
    Hi, It's a topic that everyone interests. How can I protect my software against stealing, hacking, reverse engineering? I was thinking: Do my best to protect the program for reverse engineering. Then people will crack it and seed it with torrents. Then I download my own cracked software with a torrent with my own torrent-software. My own torrent-software has then to seed incorrect data (bytes). Of course it has to seed critical bytes. So people who want to steal my software download my wrong bytes. Just that bytes that are important to startup, saving and loading data, etc... So if the stealer download from me (and seed it later) can't do anything with it, because it is broken. Is this idea relevant? Maybe, good torrent-clients check hashes from more peers to check if the packages (containing my broken bytes) I want to seed are correct or not? Thanks

  • How to disable 3rd party cookies in Chrome?

    - by David Nordvall
    I have both the "stop websites from storing local data" and the "block all third party cookies without exception" settings enabled in Chrome 12 (I'm not sure what the exact names of these settings are in english as I run Chrome with swedish localization). I do however have two problems. My first problem is that when I'm visiting one of my local news paper's site (and surely other), cookies from www.facebook.com is allowed for some reason. I suspect that the reason is that I have added an exception to the www.facebook.com domain but as the setting "block all third party cookies without exception" implies, that shouldn't matter. My second problem is that if I check what cookies are stored on my computer after browsing for a while, I have tons of cookies that are not on my white list. Primarily from ad services. My expectations from enabling the above mentioned settings was that only cookies that fulfill the two folling requirements would be accepted: the cookies must be from the domain in my address bar the cookies must be from a domain on my whitelist Apparently this isn't the case. The question is, have I completely misunderstood the settings or is this a bug? And, either way, is there a way to accomplish my desired behavior?

  • Failed to open the Parallels networking module

    - by user49204
    I'm running Parallels Desktop 7 on OSX Lion and encounter the issue in the subject on every time I'm trying to launch Parallels VM.

  • Windows 7: app crashing/hanging on "save as" dialog

    - by Fuxi
    now this is really annoying - I'm having a global problem in Windows 7: when using the system's "save as"-file dialog, the main app will just hang. the mouse-cursor is showing progress, the whole app is hanging and I need to terminate it manually. it's happening with every app! (notepad, word, graphics app). I'm assuming it's something with the system enumerating the harddisk-drivenames or something. any idea how to fix this? by the way - when viewing the problem details - it's telling the module - it's msonsext.dll, looks like some office thing to me.

  • Understanding Windows 8 Recovery options

    - by stuffe
    Background: I am preparing a PC that I am sending to a relative abroad, who has little or no internet access, and next to no sensible options for getting IT support should anything go wrong. As such I am trying to provide a full set of recovery options such that they are able to reinstall the OS with minimum fuss or assistance if required. The PC is a brand new Acer laptop that came with Windows 7 pre-installed (and an associated recovery partition) and a free upgrade to Windows 8. I have installed Windows 8 from scratch performing a format and clean install from media I burned from the official download. The existing Windows 7 recovery partition is still there, and I can still boot from it. I have created recovery DVDs of that in case it is ever lost. Here are my recovery options so far. I can perform a factory reset of Win 7 via the recovery partition I can perform a factory reset of Win 7 via burned recovery DVDs I can re-install Windows 8 cleanly from a DVD All of these are useful, but not what I want, because the first 2 methods use Win 7, and still fill the machine with crapware, and the latter doesn't provide for any post-install customisation and software installation. So, I am looking to see what other options are available to perform a Windows 8 recovery that will be more than a simple install. I am aware that Win8 comes with some useful refresh tools: Refresh your PC - Re-install Win 8 over the top of your existing installation, recovering from any Windows corruption etc. I can run this from my current install, although it says some files are missing that will be provided by me install or recovery media, which seems to be code for stick your install DVD in, and it starts after I do that - unfortunately for this particular laptop you need to specify a particular WIFI driver or the install bombs out part way through with IRQL errors, and this refresh method skips the part where you can load a driver, so it's no use to me. I think I can fix this by creating a custom recovery image using the recimg.exe command but it takes hours to complete so I haven't tried it yet. Reset your PC - Perform a full install and lose all your files. Again it needs my Install media inserting before it will do anything, but then it provides an error (will include later when I recreate it...) Now, these recovery options look useful (in principal, although both are fail for me) but they rely on having a working system to access the tools, which leads me to the last option, of making a Recovery USB drive. I have made a recovery drive, and it should perform loads of useful things, including copying my WIN7 recovery partition to the drive, providing the above refresh and reset options, providing other troubleshooting options and also the ability to restore from a custom image, only none of them seem to work for me. Creating the Recovery Drive - the option to include my recovery partition is greyed out. The partition exists and works fine, why will it not copy it? Refresh - I imagine this would have the same issues as I described before, but this is moot because when I try it says that the "drive where Windows is installed is locked, please unlock the drive and try again" with no info on what that means and how to do it. Restore - Again, probably pointless as I can just use the DVD, but it also errors: "unable to reset your PC. A required drive partition is missing" System Restore - should let me roll back a bad driver etc as per normal in Windows, only it simply says "To use system restore you must specify which windows installation to restore. Restart this computer, select an operating system, and select system restore" ?!?! System Image Recovery - this seems to be offering to restore from a Windows system image, but this is deprecated in Windows 8, although you can still make one if you use the Windows 7 Backup tools, however the resultant file is too large to put on the USB stick as it's FAT formatted, and would be a massive stack of DVDs anyway. So useless. It would be nice it it would work with the custom recovery image you can use with the refresh command, but there seems no option to do this. Automatic Repair - some diagnostics, which seem useless as it happily tells me it can't fix my problem, even though I have none. Command Prompt - yay, this works! What on earth do I want to use it for... Had any of the above worked, it might be useful, but as any form of install still requires you to have the DVD, and any form of custom recovery image also requires you to have either a massive stack of DVDs or an NTFS formatted backup device in addition to the recovery drive, it sort of ruins the point. It doesn't seem rocket science. I want to create a bootable USB drive that I can refresh Windows over an existing install with, perform a clean reinstall to a bare system, or recovery a customised image with existing apps installed. If anyone can point me in a direction that allows me to make a single recovery drive do these all these things, I would appreciate it. I have a 32Gb USB3 thumb drive that I bought for this very purpose, but it's seems to be fighting to let me do anything useful. At this rate I will be making a DriveImageXML recovery stick and dumping the OS with that, which I know works, but isn't so elegant as using the proper tools..

  • Ubuntu and Belkin N150 f6d4050 Wireless USB adapter v2

    - by Andrew
    I'm new to Ubuntu, and I'm trying to get my Belkin USB adapter to work. There are plenty of discussions out there already about this, but none really helped me out. Here's what I've done - Installed ndiswrapper Installed ndisgtk Installed the driver (rt2870.inf) via ndisgtk ndisgtk reported that the driver was installed and the hardware was present. The green light on the adapter is solid green, which I assume means that Ubuntu is aware of it's presence. However, when I click the little wireless symbol at the navigation bar, there's no option to choose my adapter (assuming that it's supposed to show up there...) My adapter version is F6D4050 - Where do I go from here? I'm a Ubuntu newb, so speak slowly. :P lsusb - andrew@ubuntu:~$ lsusb Bus 002 Device 003: ID 046d:c517 Logitech, Inc.

Thanks for any help PS. I wasn't sure if you're allowed to post questions like this, about proprietary software, but I checked the FAQ and it seemed ok. Response: The URL I am told to visit it this but I can't tell which I should choose that I am originally presented with, or what to put in to select, as I am not sure what input it is referring to.

  • Internet speed is suddenly slow only on my laptop, but it's normal in other devices

    - by Wael
    I have a TP-Link router connected to a ZTE modem, with 2 laptops, a tablet, 2 phones connected via the router's WiFi, and an additional desktop connected via ethernet to the router. Today, my laptop started to have a very slow connection to the internet, which at first I thought it was the operator's problem to find out later on that it works fine on other devices. I tried to connect directly via WiFi to the modem, but it was as slow. I cannot access facebook at all, google takes forever to do a search, and youtube barely works. The weird thing though, is that when youtube does work, the streaming is full speed. This happens also when I download a file! My browse is Firefox, but I used Chrome and IE9 with the same results. I work on Windows 7 Thanks for any advices.

  • What is the best / latest software to convert DVD recorder disc to YouTube?

    - by Jian Lin
    I recorded some Wii gameplay to a DVD-R using a DVD recorder, and tried using Handbrake to convert it to YouTube compatible format. Basically, it needs resizing to 16:9, and selecting 00:03 to 3:10 of the chapter (out of the 7 minutes). It seems Handbrake can't do it for 480p... and if using AutoGK and then VirtualDub to resize and do video time selection, it feels so old school (autogk not updated since 2005)... Windows Movie Maker seems like 15fps video quality... Is there a way to do it nicely? Details if using Handbrake: I can't find a way to convert a DVD recorded video which is 720 x 480 (Wii Gameplay in 16 : 9 ratio) into 852 x 480... It seems that the only possible resize is to shrink but not to expand? It is fine to make it 720 x 406... except YouTube won't be able to show it as 480p... If it can be made 852 x 480, then YouTube can at least show it as 480p (besides 360p and 240p)... is there any way to do it? thanks.

  • Safari corrupting downloads?

    - by Kaji
    First off, a bit of background: I had to do an erase and install about 2-3 weeks ago, so this is a fresh, up-to-date installation of Snow Leopard we're dealing with. That said, I decided recently to branch out from simply programming PHP in a text editor and explore some of the other technologies I keep hearing about, and picked up Drupal, Joomla, and the Zend Framework from their respective official sites. Latest complete, stable builds for all 3. Drupal and Joomla downloaded without a problem, but when I put them in my /~username/Sites folder, XAMPP pretends they're not there, even if I restart Apache or the laptop itself. Zend's archive won't open at all. Is Safari corrupting the downloads, or are there other issues in play that can be investigated?

  • How to recover bitlocker encrypted partition that is now 'unallocated'/'free space'?

    - by Atishay Jain
    My hard drive had 5 partitions(including 1(some 4-5GB) bit locker encrypted one). When I used disk mgmt I could view 2 partitions(24.4GB and 8.94GB) in green colour labeled Empty space. So, I wanted to merge them and I used minitool partition wizard for the purpose. I don't know, what that software did, but all I was left with 2 partitions and lots of green free space. I recovered 2 partitions using EaseUS partition master, but the bitlocker encrypted partition cannot be searched by it(and also minitool partition recovery). Now, the disk mgmt shows 2 free space partitions of 28.36GB and 8.94GB respectively. Here is a screenshot http://s14.postimage.org/4tvij041t/Screen_Shot003.jpg Please, tell me a way to recover the bitlocker encrypted partition that is showing as a free space in disk management. P.S. - It contains very important data.

  • HLS video segmenting complications. How to create a transport stream with ffmpeg

    - by Agzam
    I have h264 videos, and currently we're using Apple's HTTP Video Streaming tools and mediafilesegmenter to segment these files. What I need to do is to switch to alternative segmenter based on this very popular open-sourced segmenter The problem is that this segmenter does not just take any video, but takes only MPEG-TS videos. So I have to convert my h264 videos to TS first. I can do that with ffmpeg. I'm using this: ffmpeg -i encoded.mp4 -vcodec h264 -i encoded.mp4 -sameq -acodec aac -strict experimental -f mpegts output.ts But this creates fairly larger output. And the reason is that Apple's segmenter keeps the same codec - AVC and the same audio codec - AAC, whereas ffmpeg changes video format to MPEG Video. The question is: can I somehow keep the same AVC video codec and still convert video to a transport stream? So my goal is to keep the same video quality and same video codecs as Apple's medifilesegmenter does. UPD: Okay... it seems that ffmpeg CAN split videos into segments: ffmpeg -i encoded.mp4 -c copy -map 0 -vbsf h264_mp4toannexb -f segment -segment_time 10 -segment_list test.m3u8 -segment_format mpegts segment%d.ts That's still has one problem: it doesn't create http live streaming index file. (-segment_list creates a file with list of segments, but it doesn't look like HLS index). So, you still have to create index file

  • Create tunnel through an open SSH connection?

    - by criptych
    I have a remote PC (behind NAT and firewall) set up to create a reverse SSH tunnel to my home PC/server (DMZed). Unfortunately, the tunnel hasn't been working lately. Fortunately -- I think -- the remote PC currently has an SFTP session open to the local one. My question is, can I create a tunnel back to the remote PC through that session? Or am I SOL until I can physically get in to restore the reverse tunnel on the remote PC?

What's more, memory usage is growing all the time. I've had to restart my server once a week, because once my 256mb fills up it starts swapping, which it wouldn't do just for disk cache. Shouldn't there be some way for me to see the culprit?! I'm new to server admin, so please if there's something obvious I'm overlooking point it out to me. Just for good measure, the output of cat /proc/meminfo: MemTotal: 251140 kB MemFree: 124604 kB Buffers: 20536 kB Cached: 66136 kB SwapCached: 0 kB Active: 65004 kB Inactive: 37576 kB Active(anon): 15932 kB Inactive(anon): 164 kB Active(file): 49072 kB Inactive(file): 37412 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 524284 kB SwapFree: 524284 kB Dirty: 8 kB Writeback: 0 kB AnonPages: 15916 kB Mapped: 10668 kB Shmem: 188 kB Slab: 18604 kB SReclaimable: 10088 kB SUnreclaim: 8516 kB KernelStack: 536 kB PageTables: 1444 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 649852 kB Committed_AS: 64224 kB VmallocTotal: 34359738367 kB VmallocUsed: 752 kB VmallocChunk: 34359737600 kB DirectMap4k: 262144 kB DirectMap2M: 0 kB EDIT: I had misinterpreted the meaning of free -m at first. But even so: the important thing is that my OS eventually begins to use swap memory if I don't restart my server, which disk caching wouldn't do. So where do I look to see what is using all this memory?

  • How to kill unkillable Python-processes running as root

    - by Andrei
    I am experiencing an annoying problem with sshuttle running it on 10.7.3, MBA with the latest firmware update -- after I stop it (ctrl+c twice), or loose connection, or close the lid, I cannot restore it until I restart the system. The restarting takes notably more time, than it would normally take. I have tried to flush ipfw rules - not helping. Could you advice me how to restore sshuttle connection (without restarting os)? The following processes remain running as root, which I do not know how to kill (tried sudo kill -9 <pid> with no luck): root 14464 python ./main.py python -v -v --firewall 12296 12296 root 14396 python ./main.py python -v -v --firewall 12297 12297 root 14306 python ./main.py python -v -v --firewall 12298 12298 root 3678 python ./main.py python -v -v --firewall 12299 12299 root 2263 python ./main.py python -v -v --firewall 12300 12300 The command I use to run proxy: ./sshuttle --dns -r [email protected] 10.0.0.0/8 -vv The last message I get trying to restore the connection: ... firewall manager: starting transproxy. s: Ready: 1 r=[4] w=[] x=[] s: < channel=0 cmd=PING len=7 s: > channel=0 cmd=PONG len=7 (fullness=554) s: mux wrote: 15/15 s: Waiting: 1 r=[4] w=[] x=[] (fullness=561/0) >> ipfw -q add 12300 check-state ip from any to any >> ipfw -q add 12300 skipto 12301 tcp from any to 127.0.0.0/8 >> ipfw -q add 12300 fwd 127.0.0.1,12300 tcp from any to 10.0.0.0/8 not ipttl 42 keep-state setup >> ipfw -q add 12300 divert 12300 udp from any to 10.0.1.1/32 53 not ipttl 42 >> ipfw -q add 12300 divert 12300 udp from any 12300 to any not ipttl 42 Update: $ ps -ax|grep python 1611 ?? 0:06.49 python ./main.py python -v -v --firewall 12300 12300 48844 ?? 0:00.05 python ./main.py python -v -v --firewall 12299 12299 49538 ttys000 0:00.00 grep python

  • No sound (USB speakers) in Ubuntu 9.04 Jaunty Jackalope

    - by Mike
    I just installed Ubuntu 9.04 and have been unable to get sound functioning. I have a set of USB speakers (not USB powered with a stereo plug... they are totally USB). I've tried plugging them directly into the tower as well as into the USB port on my Dell 2405FPW monitor. Both USB ports are functioning correctly (I tested by sticking a flash drive in there - they both read it), and the speakers are functioning correctly in Windows. If it's relevant, I have an SB Audigy 2 sound card that came with the computer, but is not being used. Any ideas? Thanks! EDIT: These are the speakers - Logitech S-150 USB Speakers
