• how to recover lost partitions data

  - by TheJoester

  I have a 2TB SATA drive that was being used as file storage on my UBUNTU computer. I was re-imaging my windows box so I used that drive to back up some files to it. I did this by taking the drive from my windows PC and putting it in my UBUNTU PC, mounted it and copied the files over. After the windows refresh I thought it would be easier to take the 2 TB drive and dock it in the external dock my Windows case has built in. Anyway it would recognize in BIOS but windows would not see it (because it was EXT3 or EXT4) so when I went into the disk manager it advised me the drive needed to be initialized. Me not thinking I initialized it as a GUID Partition table. Now it sees it as a blank drive, even in UBUNTU. I have done nothing else to write or change the drive. I was wondering if there is a qay to repair the old partitioning and get access to my files back? many thanks! EDIT: I followed the instructions in the link @kniwor sent me. I used the command sudo gpart -W /dev/sda /dev/sda and here was the result: Guessed primary partition table: Primary partition(1) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(2861671176-2861671176) chs: (1023/254/63)-(1023/254/63)d (178130/202/1)-(178130/202/1)r Primary partition(2) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(3484550160-3484550160) chs: (1023/254/63)-(1023/254/63)d (216903/55/1)-(216903/55/1)r Primary partition(3) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Primary partition(4) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Not sure it found what I wanted. suggestions?

• Why do some actions not work with Remote Desktop?

  - by Holgerwa

  I usually connect to other PCs in the same building using Remote Desktop, which works great. For some reason, some actions cannot be performed through Remote Desktop. These are, for example: Installation of certain software Accessing the directory of a DVD (that is inserted at the remote computers drive) several other tasks that just "don't react or start", unless you do the same thing without RDP All these actions work with any other remote access tool, like VNC, Teamviewer, LogMeIn, etc. My question is: What is the difference when I use a computer through RDP instead of directly? Is there a list of prohibited actions available so that one could know upfront if something can be done with RDP or not?

• Re: # 47209 How to copy an Existing HD to a new one and have it be bootable?

  - by user281151

  Help please! My backup method of choice is to clone my "working" drive to another identical drive. I have 2 windows drives and I clone my working one to the other one once per month. No problem - each will boot if I select it. Now with the lack of future support for XP, I am getting familiar with Ubuntu 14.04 LTS. I have it on one drive and I have a second identical drive that I want to be able to clone it to once/month. Not as necessary to do this with Ubuntu as with windows, I know, but I'm anal. So I have followed #47209 MestreLion's procedure with just the two Ubuntu drives "on line". I.e., boot my "working" drive with Live CD, use Gparted to be sure I know what's what, open terminal and enter and execute the dd command, Go to bed till the clone is done, shut down the computer, disconnect the input/source drive, boot up using BIOS to select the remaining output drive. The drive starts fine but all is not OK. It puts up a screen that says I'm on a Guest Session and asks for a password. Well, for one thing I have my Ubuntu set up to start without a password being entered. I have one, of course, I put it in but it isn't accepted. I can't get by this Guest Session screen. I am fine, of course. I can disconnect this drive, hook up my "main" ubuntu drive and all the rest, and go on with my business. But I don't have the desired "emergency backup" drive working where I could jump on and use it immediately if I needed it. Can someone give me some guidance here?? What (else) do I need to do. Love Ubuntu but learning. Thanks, Wes.

• Keeping the wireless connected.

  - by casr

  I’m running OpenBSD on a computer which is connected via wireless to the network. It is a well supported NIC and I’ve had no problems with it from a hardware perspective. Unfortunately my wireless access point occasionally loves to forget it’s settings. I then have to help it remember. However, in this intervening time my OpenBSD box drops the connection and then does not automatically reconnect. I have alleviated my problems by running this simple script in the background: #!/bin/sh while [ 1 ] do ping -c1 192.168.1.254 > /dev/null if [ $? = 1 ] then sh /etc/netstart ral0 > /dev/null fi sleep 30 done [Ping the access point. If there is no response attempt to reconnect.] It seems to me to be a very suboptimal solution. Has anyone else come across a better way?

• Passwordless ssh on multiple machines

  - by Phil

  Hi all, I'm quite confused with all the ssh security stuff. I am trying to reconfigure a system that is currently broken for reasons unknown. Machine A is your personal computer that you use whenever you're at home. Machine B is the head node of an HPC cluster and all the other machines C are all identically configured machines which share the home directories of machine B. This is an HPC cluster if you haven't guessed. How would I configure passwordless ssh between any nodes B or C. A can only get to C through sshing into B

• php.ini settings change not taking effect for large file uploads

  - by user51347

  My server was just reprovisioned, and my application which uploads large (100M+) files now breaks upon re-installation. the symptom is quite consistent : smaller files (8mb in my tests) upload just fine. Larger files cut off at quite close to the same point every time given a particular computer. a file that fails at 26% will fail at just about the same every time. One that takes 1:40s to fail will take within 2 seconds of that every time, before failure. I have set my php.ini settings extravagently : post_max_size = 512M upload_max_filesize = 512M max_input_time = 3600 max_execution_time 3600 Is there possibly a setting at the Apache Level which would override PHP?

• Delete Grub and OpenSuse but keep Windows 7.

  - by elvispt

  Hi. Here is my problem. I have OpenSuse installed alongside Windows 7. Grub is the boot loader from where I access OpenSuse and Windows 7. I want to delete Grub and also the OpenSuse partitions. My first, failed, approach was to insert the Win7 DVD, choose Repair your computer and then enter the commmand prompt. I then typed "bootrec /fixmbr" and restarted. It didn't worked. Grub was still there, so was Windows7. I then tried using "bootrec /fixboot and /rebuildbcd and neither worked. So what can I do to fix this? I remember when I was using WinXP this was much simpler. I would just type fixmbr and that was it. Any clues? Thank you.

• What is the preferred pattern when attaching a 'runtime object'?

  - by sebf

  In my application I have the following: public class NeatObject { /* lots of static data, and configuration flags */ } public class NeatObjectConsumer { void DoCleverStuffWithObjectOnGPU(NeatObject obj); } Where NeatObject and its consumer are used to control the GPU. The idea being that, the configuration of an instance of NeatObject and its members, define how the consumer instance behaves. The object can be passed around, edited, and most importantly serialised/deserialised by the application, with and without knowledge of NeatObjectConsumer, then provided back to the consumer to do something else. The purpose of this seperation is: The consumer manages hardware resources, which change depending on the computer, and even on the execution of the application, making preserving the state of an object which does everything difficult. Avoids circular references if the assembly that contains the consumer needs to reference one that only needs to know about NeatObject. However, there is a complication in that the consumer creates hardware resources and needs to associate them with NeatObject. These don't need to be preserved, but still need to be retrieved. DoCleverStuffWithObjectOnGPU() will be called many, many times during execution and so any bottleneck is a concern, therefore I would like to avoid dictionary lookups. What is the preferred method of attaching this information to NeatObject? By preferred, I mean intuitive - other coders can see immediately what is going on - and robust - method doesn't invite playing with the resources or present them in such a way as to make them easily corruptible. Essentially, I want to add my own metadata - how should I do it? Try to use 'actual metadata' functionality like Reflection? A member of the type of an abstract class? Unmanaged pointers? If you took on a project that used this pattern, what would you have liked the previous developer to do?

• Compatible case?

  - by Rick

  Hello everyone, first of all, I'm not sure where this question should go. So I've looked around and found the 'hardware' tag used in superuser.com please forgive me if I'm posting this on the wrong site. I'm new to the hardware part of computers. I've been looking around for a few months and now is the time to make my choice. I want to build my own computer and I think I got all the items I need. I want to know if the case and the motherboard I've chosen are compatible or if you could tell me how to check if they're compatible I want to know if they fit. Here's the motherboard/processor/memory package And this* is the case I'd like to fit it in. I'm sure that all the other stuff I might need I have with me already. Thanks in advance -Rick *See my comment, I may not post two hyperlinks due to spam protection

• Server Requirement and Cost for an android Application [duplicate]

  - by CagkanToptas

  This question already has an answer here: How do you do load testing and capacity planning for web sites? 3 answers Can you help me with my capacity planning? 2 answers I am working on a project which is an android application. For my project proposal, I need to calculate what is my server requirements to overcome the traffic I explained below? and if possible, I want to learn what is approximate cost of such server? I am giving the maximum expected values for calculation : -Database will be in mysql (Average service time of DB is 100-110ms in my computer[i5,4GB Ram]) -A request will transfer 150Kb data for each request on average. -Total user count : 1m -Active user count : 50k -Estimated request/sec for 1 active user : 0.06 -Total expected request/second to the server = ~5000 I am expecting this traffic between 20:00-1:00 everyday and then this values will decrease to 1/10 rest of the day. Is there any solution to this? [e.g increasing server capacity in a specific time period everyday to reduce cost]

• How to tell, before buying, if a given graphics card will play Full HD video?

  - by Dominykas Mostauskis

  I am looking for the cheapest video card that would be capable of smooth playback of Full HD (1080p) video on a Full HD screen. An answer by @Mikhail on a related question briefly mentioned that: performance of video playback is largely dependent on the video accelerators present [in the card] Is this true? Could anyone expand on that? Are there any benchmarks or specifications that could be used to tell if a given (low-end) card can play Full HD video smoothly? Benchmarks I encountered are oriented towards computer games, and using them to evaluate video playback performance may be less-than-optimal, I imagine.

• How can I continue audio playback even after switching user?

  - by klyonrad

  I just tested it with iTunes; after switching the user account (only after logging into another account, to be precise) the audio playback from the account "A" stops. However iTunes continues playing in the background; which I realized after switching back to account "A". Very frustrating because it kind-of is a deal-breaker for me; the other person should be able to have some personalized settings; while it is still my computer, and the main account has all the music obviously. The ideal solution would be audio output continuing running while user still has the ability to manually pause it... EDIT: I tested a bit more: "Desktop" apps like VLC don't output sound but continue running; the stock Music.app in Metro pauses the music and continues playing when switching back.

• Video streaming and internet browsing on different bands/frequency

  - by user47207

  I have a Netgear WDNR37000 which allows clients on a 2ghz or 5ghz to access the internet and see every client and device on the network. I have a computer with two nics, one that is in the 2ghz range and the other on the 5ghz range. My specific problem is that I would like to serve my video streams (hulu, ps3mediaserver, playon) to my ps3 on the 5ghz band while internet browsing is routed to the 2ghz band. This is so that the video streams aren't affected by general internet use. While the easiest solution would be to disable internet access on the 5ghz apn, I would like to know of a solution that would not require that.

• [Outlook 2007] How to recover the deleted Tasks from a Deleted Profile?

  - by JoshuaD

  Edit: OK. I've found the OST with the tasks in it, but I am unable to import an OST into outlook, it appears it needs to be converted to PST first. Is there anyone who knows a free OST - PST converter or some way to import OSTs directly into outlook? I am using outlook 2007 linked to an MSN email account through outlook connector. I recently added [email protected] (Fake address) to my outlook and deleted [email protected]. I thought my tasks were locally stored seperately from the email address, but it turns out when I deleted [email protected], I also lost all of my tasks. This is catastrophic. Is there any way to recover them? They're not stored on the MSN web account. I figure they must still be somewhere on my computer. I just don't know where to look or how to look there. Thank you.

• Efficiently installing fully-patched Windows XP, IE, and Office 2007 on an isolated PC

  - by JPaget

  I have been tasked to install Windows XP, IE, and Office 2007 on a computer that will become part of a standalone network not connected to the Internet. What is a good way to install all of the security updates? I'm installing from CD's of Windows XP SP2 and MS Office 2007. Next I plan to download Windows XP SP3 and Office 2007 SP2, burn them to CD's, and install both service packs. Finally I plan to go to the Microsoft Download Center and download all applicable security updates, burn then to CD, and install them. I estimate that there are over 100 of these updates. Is there a more efficient way to do this?

• Is there a way to customize items on the right side of start menu in Windows 7?

  - by Basara

  OK I know I can right click on it and select properties... But it only allows me to decide whether an item is shown or hidden. What I want is, adjust item position on the start menu right side. More specifically, I want to put the item "games" in the same group where personal folders are. It makes perfectly no sense to put "games" with "computer" and "network" in same group. Or is there a registry tweak can make this possible? Thanks.

• How to Activate wifi in Toshiba Satellite C655?

  - by user4106

  I've recently bought a Toshiba Satellite C655. It came with Windows 7 preinstalled. I've never had a notebook before, but as a desktop user, I was a Ubuntu user since 2 years, and I've never had a problem with drivers, wifi, etc. When I tried to install the Ubuntu 10.04, and also the new and fresh 10.10, in my new laptop, I experienced some troubles with some of the componentes of my computer. For example, I was not able to activate my wi-fi card, although I know the kernel recognizes it correctly, because when doing "lspci" at the terminal, it was listed. Anyhow, I'm not able to "activate" the wifi, or whatever it's necessary to do in order to be able to search for public networks available, and to connect with them. The wifi-card the laptops brings is the (the lspci output): 03:00.0 Network Controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01). It's anything in you can help me? Thanks a lot in advance! Edit Neither solution seems to work. In first place, i've tried installig what hhlp told me. After the installation, nothing seems to change: on right-clicking the wireless icon, it seems to recognize the card, because the option "Enable wifi" was ticked. But, once again, i was not able to "turn the wi-fi" on. In second place, i didn't try installing the drives, because the card is already recongnized. The issue is that i cannot seem to turn it on! One thing i've probably missed is that the Toshiba cames with a windows sofntware that allows you to enable / disable the wifi tools. So, it does not have an external "button" to turn it off. I don't know if that's the problem, but i have the feeling that the issue may be aroud there: in how to turn ON the wifi-signal (or to verify if it's on or off) in my ubuntu.

• How can I reset windows 7 file permissions?

  - by ssb

  I looked at this post and it seemed to be close to what I want, but my case might be a little worse: How can I reset my windows 7 file permissions to a rational state? Basically a while back I (very stupidly) changed the permissions on all sorts of system folders, and eventually rendered my computer virtually unusable. I managed to hack administrator privileges back onto key folders and getting it working, but in doing so I only modified permissions a lot more away from the natural state. I'm looking at this icacls stuff, but ultimately I need to reset EVERYTHING back to what it was in The Beginning, before I messed with it, from the C: directory all the way down. Right now application data is what's giving me problems, and I can't get it to work no matter how much I fiddle with those specific permissions. I will be forever grateful for help on how to do this without having to reformat.

• Update-manager fails silently on 14.04

  - by pabuisson

  I recently reinstalled a lubuntu from scratch, to upgrade to 14.04. Everything's working as expected, except for the update-manager that silently fails when trying to upgrade my system's packages. It does correctly list the packages to be upgraded, I can then click on the "Install now" button (or something like this, I'm running a French flavour of Ubuntu). When I click the button, it seems unresponsive for 5 to 10 seconds, then the upgrade dialog with the progress bar appears, displays "Loading package list", then very shortly something about "authentication" (not long enough so that I can read it).. and closes. The install is fresh and I have no idea where to look. I tried launching update-manager in a term but it doesn't display any error when it fails, only this message when the window first shows up : ** (update-manager:3642): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-m0jkFlZ3yo: Connexion refusée. Any idea where this might come from ? I can upgrade the packages using the command line and sudo apt-get but this is not my computer, and I do not wish its owner to have to do this to upgrade the packages. Thanks for your help !

• Vista Startup - Cannot Find the File Specified

  - by Redmastif

  Yesterday I restarted my laptop because my Wi-Fi catcher wasn't working correctly, and when the computer reached the login screen, instead of showing my user account it said "Cannot find the file specified". I rebooted and ran the Startup Repair and Memory Diagnostics but nothing showed up. I also took the battery out for a minute and tried again but still no luck. The weird thing is that I cannot even boot into safe mode, it still shows the same error. I don't remember downloading or opening anything suspicious recently, and I have 3 different cleaners/anti-malware programs as well that I usually run about once a week. I did go into the registry recently but I didn't modify or delete anything as I was only checking to see if I had a certain key in it. I have a Dell laptop running Vista Home Basic SP2. If I have to I can reinstall the OS with the CD or even take it to Best Buy but I'd rather try and fix it first. Thanks.

• Starting Apache through XAMPP is not working

  - by nogamo

  I've checked the error logs for this particular problem and it seems no access can be made to port 80. (OS 10013)An attempt was made to access a socket in a way forbidden by its access permissions. : make_sock: could not bind to address [::]:80 Turning the Windows firewall off didn't work, so I'm a bit lost. All of this is running on my laptop so I don't have my own "server" per se but I was under the impression that this would work without the need for one independent of my own personal computer. How would I solve this?

• Redirect audio from laptop to desktop over LAN

  - by Ram Rachum

  I want to be able to play a song on my laptop and have it sound through my desktop's (infinitely better) speakers. If you're familiar with Input Director: I want something that is to audio what Input Director is to mouse/keyboard. I want something that automatically redirects all audio from the laptop to the desktop in real time, and I want that solution to require, like Input Director, minimum maintenance. Beyond the initial setup, I don't want to have to babysit the program that does this. I want something that launches automatically with Windows and just works, and also allows me to cancel it whenever I want. And also doesn't go crazy when the laptop is turned on in a different network where the desktop computer isn't available. Any suggestions for such a program? (I use Windows XP on both computers.)

• Can I use static routing to allow me to use my public IP from my LAN?

  - by jnm2

  I would like to be able to use the same hostname to connect to my computer from my phone whether I'm at home or away. Currently I have to maintain duplicate entries for remote desktop, for instance. My router doesn't seem to have a NAT loopback option. I have two routers in fact, a cable modem which goes straight to my main router which does wireless. I can add to the static routing tables on each. Can I use this to loopback the public IP or do I need different routers?
