• Laptop screen is cracked, external monitor only mirroring the broken laptop screen

  - by user92415

  I did something stupid. When my Dell Vostro 1000 laptop screen cracked and went all crazy and I couldn't see anything, I attached it to an external monitor and pressed Fn + F5 and it worked. But then I did something in the control panel that made the external screen look similar to the laptop screen. That made the external screen completely unusable too. In the control panel it was the last tab – something with "dual screens" I think. Is there anyway to reverse what did, turn off the laptop screen permanently and turn the external monitor into the primary? Remember that I can't see anything on the laptop screen. It is a complete goner – and because of what I did I can't see anything on the external monitor.

• Not able to access external Hard disk

  - by Jash Jacob

  I have a 1TB External Hard drive which I'm currently not able to access. When I open the External drive in Finder, It shows it's empty. When I use the option to "Get Info", I get the dialog box stating it has about 300GB Free. Tried to get into the External Drive using Terminal, I had no luck. Checking in Disk Utility, It showed that I have many number of files but ZERO folder. I tried to "repair disk", in the process the external Drive got unmounted in between the process. I checked this drive on Windows. I was able to open almost all the folders but I wasn't able to copy anything onto the external drive. One folder caused my windows computer to hang, So i connected the drive back onto my MacBook Pro and tried to access the drive through terminal (this time it worked!) and then I tried to delete the folder with rm command, I got an "input/output error" What should i do to recover the files in that folder? How can i access my external drive on my mac

• Disable laptop's display on boot when used with external display

  - by Ryan

  I keep my laptop tucked away and solely use an external display with it via HDMI. In Windows 7 display settings, I have it set up to "Show desktop only on 2 [my external display]" This works fine in all cases except when I boot the laptop when the external display is already connected. In that case, the laptop's display stays on and sticks at the Windows 7 boot logo unless I manually shut the display off. (I should mention that while the laptop's display is stuck at the boot logo, the external monitor and computer are running just fine.) The laptop is an Asus N56VZ with Nvidia 650m graphics and the latest drivers. I've checked Nvidia's control panel as well as the BIOS and nothing looked very promising. Any ideas as to how I can get my laptop screen to shut itself off after booting into Windows?

• MySQL unstable behavior with external stroge

  - by onurozcelik

  In our project we are using MySQL 5.0.90(InnoDB engine) server with an external storage. We store MySQL data files in an external storage. When the external storage down for a reason we have unstable behaviours. So we made some tests. In Windows Server 2008 We closed external storage physically. MySQL service stoped and we could not reach the server. Then we opened the storage unit and we could not start service until we reconfigured MySQL. We made storage unit offline from operating system. After 3-4 minutes and some insert trials(some insert trials succeded) MySQL service stoped and we could not reach the server. Then we made storage unit online and we could start the service(not automatically). In Windows Server 2003 We made storage unit offline. After 3-4 minutes and some insert trials(some insert trials succeded) MySQL service stoped and we could not reach the server. Then we made storage unit online we could not start the service until we reinstalled MySQL. Before reinstall we tried to reconfigure but it did not work. We closed external storage physically. MySQL service stoped and we could not reach the server. After that we opened the storage unit and we could start service(not automatically) We expect service to autostart after storage unit is online/open. But these tests show unstable behaviors. Is there any solutions to this.

• how to setup sonicwall tz210 to port forward packets received from external ip to another external ip

  - by lplp

  i have a sonicwall tz210 on a fixed ip, say ip1. And then i have, let's say a legacy server, with external ip ip2, which sends data to ip1 (and I have another server on ip1 behind the sonicwall which receives and processes that data). I would like to set up a new server on a different external ip ip3 that will receive and process data from the legacy server. How can I setup the sonicwall so that the packets received from the legacy server (from an external ip) are port forwarded to the external ip address ip3?

• Grounded outlet on external hard drive.

  - by goathens

  Is there any value in getting an external hard drive with a grounded power supply? Would grounding the drive protect it from a static jolt from my hand when I pick it up? I've only really ever used the huge 5.25" external housings (they usually have an integrated power supply and use the standard heavy PSU cable with ground), and I need some more but noticed while shopping that the current trend is towards smaller enclosures with the external brick (and hardly ever grounded).

• Why are the external IP of my router not the same as the external IP of my computer

  - by Martin

  I have a standard network setup where all my network devices, both WIFI and ethernet, are connected to the same router. Lately, however, I've been experiencing some very strange behavior. It started as a simple connecting error, when I tried to reach an FTP server using the external IP. Of course I went right into one of those CheckMyIP sites, to double check the IP and it turned out to be correct. Then I went into my router setup, which is through a tool called aiport-tool, because I have an Apple Aiport Extreme router. Turns out the router displays a different external IP, and for some reason that external IP works when I try to access the FTP server. Can anyone explain what is going on? Why are the devices connected to the router displaying an incorrect external IP? BTW i have no VPN/proxy setups on any of my devices.

• Working with an external button box

  - by Scott

  I tried this question on Stack Overflow, but I was pointed here, so here goes: For a new project for myself, I am looking for a way to be able to (for example) open a pop-up window on my laptop, by pressing a button on an external device (to be build by myself, or at least bought) connected with USB. Basically I would be looking at something like a Arduino or Raspberry (IF I am looking in the right direction) with buttons on it, and as soon as I hit a button on the external box with physical buttons, a command activates on my laptop and for example opens a popup window in which I can input tekst. Does anyone know: 1) if it is possible to do this at all. 2) What equipment is needed for the external box, what programming is needed. I preffer .net (dot net) but maybe it can only be done with software from the external box. If anyone can point me in the right direction, like make/model of the external box or websites I would be very happy. I have knowledge of Visual Studio/.net but I am willing to learn other languages if .net is not an option for this project. Thanks in advance Scott PS: If anyone knows of some better tags, or at least knows what I mean and needs me to edit the question, please do tell me... I am new on Stack Overflow/Superuser.

• Installing Ubuntu on an External Drive

  - by Dom

  I am trying to install ububtu on an external drive. I am a programmer who wants to start using Linux. I downloaded the usb installer from the ubuntu website and followed all the steps. But when I get to the part where I have to setup the partitioning, it says an error when moving forward "No root file system is defined". I've been doing some research and I think that I have to partition the external drive but do not know how to do so. The problem is that I only want 20gb used from that external drive and let the rest be used for storage. I am also a musician and use Pro tools so I would like to keep all my files there, but I dont want ubuntu on my main hardrive since the external one is portable. I'd appreciate it also if you could provide me the steps.

I need to get Windows to install onto my external hard drive (where Ubuntu is as well). The iso disk will not install windows to the hard drive. Can anyone help guide me through the process of getting windows on the external?

• Windows XP machine not seeing external FAT32 partitions correctly

  - by Rob_before_edits

  About 8 months ago my Windows XP machine stopped being able to see FAT32 external drives when I plug them in... mostly. I will explain... It happens with all my FAT32 drives, whether they be unpowered external hard drives, powered external hard drives, SDHC cards plugged directly into the machine's card reader, or SDHC cards plugged in via a separate USB card reader. All of these drives/cards used to work fine on this machine. They all stopped working at about the same time. NTFS volumes are not affected. If I plug in NTFS external drives they are recognized right away. I even have one external drive with two partitions on it, one is NTFS which is recognized, the other is FAT32, which is not recognized. If I attach a FAT32 drive, then reboot, then the drive almost always becomes visible to the machine after the reboot. Sometimes I can plug in a FAT32 drive and it works right away. Not often though. I'd say I get lucky more often with SDHC cards than hard drives. I'm developing a theory that I only get lucky with hard drives if I'm running Acronis Disk Director when I plug them in, though that usually doesn't work either - I need more data here, this may be a red herring. Getting lucky with a hard drive is really rare, usually I have to reboot. When a FAT32 is recognized, either because I got lucky or because I rebooted, I can almost never safely disconnect it. It tells me "The device 'Generic volume' cannot be stopped right now. Try stopping the device again later". I can't seem to get around this. IIRC, I've tried closing every open window, and still no luck. Since I care about my data usually the only way to disconnect a FAT32 drive is to shut down the machine. As you can imagine, two reboots just to read a drive is getting pretty old... When the machine fails to see a FAT32 drive it usually comes up with the appropriate drive letter and the words "Local Disk" in Windows Explorer instead of the correct partition name. If I click on it I get "J:\ is not accessible. The parameter is incorrect." Before this problem arose I always clicked the "safely remove" button for everything, including SDHC cards where I think it's not necessary. I've known for a long time that this is the correct procedure for hard drives, so I don't think failing to do this was the cause of this problem (before someone asks :) Any answers or suggestions most welcome.

• How to install an OS on a external hard drive

  - by Nrew

  I made a little research before coming here. And found out that I need to disconnect all internal hard drive before proceeding. http://www.pendrivelinux.com/installing-ubuntu-to-a-usb-hard-drive/ Here's my question: If I install Windows XP or Ubuntu on an external hard drive. Would it be universal? Can I use it or run it on any computer. Assuming that the bios allows you to boot from USB hard drive. Or even not because there's PLoP Bootmanager And has the considerable amount of memory and processor power to run the OS. What other things to consider when installing an OS in an external hard drive? Is installing in the external hard drive the same as when installing in an internal hard drive? Can I also boot multiple OS? What are the things to consider when doing this? And if you have a tutorial there. Showing how to install an OS in an external hard drive. Please link.

• external drive enclosure -> software RAID 5?

  - by memilanuk

  Hello all, I have two older PCs on my LAN posing as 'servers'... one running FreeNAS off a USB stick using three 500GB hdds in a ZFS RAID-Z pool serving as storage for the LAN and one running Debian Lenny with an 80GB drive used as a general purpose 'tinker' box that I can ssh into, etc. Problem is that the SMART report for one of those 500GB drives in the FreeNAS box is showing some pre-failure attributes, and the whole array is a little small anyways. Rather than simply replace one 500GB drive with another 500GB drive, and have no backup of the file server, I'd like to upgrade all the drives to 2TB ones - but I have no where to store that much data in the mean while. As such, I started looking at getting a 4-bay external drive enclosure with an eSATA card for the Debian box, with the hopes of creating a RAID5 + LVM setup using those drives and backing the data up to that external drive enclosure. After the backup is done, replace the drives in the FreeNAS box and rebuild the array there and mirror the data back. Then, I'd have both the primary storage (on the FreeNAS box) and a backup (which I don't have currently) using the external drive enclosure on the Debian box. My big question is... most of these external drive boxes seem to claim support for JBOD, RAID 0, 1, 10, 5, etc. - should I presume that is simply fake RAID like many commodity mobos have, and not really usable in Linux? In that case, with all the drives hanging off the one eSATA connection, will Linux (specifically Debian Squeeze, as I plan on upgrading that box here shortly) see all four drives, or just the first one? Will I be able to configure them in a RAID5 array as desired? Thanks, Monte

• Closing laptop lid and using external display causes mouse to move on it's own

  - by PolishHurricane

  I plugged my ASUS Taichi Laptop into an external monitor via the VGA Adapter that it comes with. It was working fine, but then I configured a power option so I could shut the lid without it going to sleep (so I could use just the external monitor with an external keyboard/mouse). Problem is though, now, when the lid is closed and I move the mouse, the mouse is moving around on it's own, but when I open the laptop lid back up, the mouse is fine. I looked under the lid when it was closed and the display properly shuts off on the laptop. It's not the external mouse/keyboard because I completely unplugged them and it was still happening. Nobody is hacking me or anything, I totally went into airplane mode/pulled the wire. I have a touchscreen, but I put a piece of paper over it and it wasn't doing it. I was thinking it might be the trackpad being touched somehow by the screen when the lid is closed? But I went into windows 8 control panel options and I couldn't find anywhere to disable it (it sees the USB mouse I think).

• Compiz and Desktop Effects on Netbook with External Monitor

  - by Nerdfest

  I have an Acer Aspire One AO150 and am having trouble plugging in an external monitor under Ubuntu 9.10. There were no problems under 9.04. If I plug in an external monitor once the machine is already up, then bring up the 'display' application to activate it, it basically hangs. There are no problem under these circumstances if I have desktop effects turned off. I've seen a few mentions of this problem on the Ubuntu forums, but never a solid solution. Any ideas? A few more details after a question below. The machine does not respond to its keyboard commands to switch to an external monitor, nor does it respond to Ctrl-Alt-F1, etc to switch out of X. The pointer is visible on the monitors (at the edge of each) and is frozen as a 'busy' cursor, but with no animation. The kernel does respond to SysReq commands (REISUB). In the latest attempt I had the external monitor active earlier, then removed it and activated desktop effects. Upon plugging in the eternal monitor then bringing up the display application, it hangs.

• Partition External Harddrive already using Time Machine?

  - by Wex

  I have a 1TB external that I've used to backup my Mac for the past year using Time Machine. Unfortunately, my hard drive is getting close to full, and I'd like to move some of the stuff off of my Mac onto the same external drive. The problem is that the external drive is already full with my Time Machine Backups. I'd like to partition 750GB to the Time Machine Backups, and save the other 250GB for personal use. Is there any way I can go about this without corrupting my current backups? I'm willing to delete some of the older backups if necessary; again I'm just worried about corrupting the data.

• External hard drive encryption

  - by Kragen

  I've got a complete backup of my main PC on 1.5 TB external hard drive that I carry around with my laptop so I can have access to all of my files while I'm on the move, however it has just dawned on me that if someone nicks my external hard drive they now have access to everything! Hence I'm looking for a way to encrypt my external hard drive. I'm after something that is: Secure (if I need to carry around a USB dongle to keep the key on so be it) Fast (the performance of the drive should still be reasonable) Cross-platform (I regularly use other peoples computers - Sometimes they are not windows based and might not even have internet access, however I still want to be able to access my files) Cheap (preferably free / open source!)

• Tools to backup an external hard disk

  Hey people, What's the best method to take an exact copy of my external hard disk? A guru suggested rsync, but I was wondering if there's an easier alternative. I do remember reading somewhere that Acronis also does this. Was looking for your advice on the best option. I'm running Windows. Essentially i have an external HDD which has a lot of stuff synchronized across various pcs. I wish to take a backup of this external Hard disk (ext.HDDs aren't entirely reliable so want to keep a backup of my ext.HDD). Cheers. K
