• Lost HDD partition to clean command, testdisk unresponsive

  - by Sujay Anjankar

  I accidentally cleaned my external HDD by the clean command in Diskpart and got a full sized heart attack after that. I did some research and I have tried a number of tools already. To name a few: Testdisk Recuva Partition Find and mount Eassos Recovery I have even tried some other dumb sounding tools, but none of them could find the lost partition. They just show "no partition found". Testdisk shows Partition sector doesn't have the endmark 0xAA55. The file recovery softwares list the files, but none of them seem to be able to restore the lost partition. I need to recover the disk as it was. Any help would be much appreciated!

• HP Envy webcam pictures all purple

  - by kousen

  I have a new HP Envy 15 with an integrated webcam, running Win 7. It works, but all the images are purple, suggesting to me that the red and blue guns are working, but the green isn't. The problem shows up on both their own software and on Skype. I talked to tech support, and they had me update the BIOS, reinstall the hardware BIOS for the webcam, and update the webcam software. It therefore sounds like a hardware problem, but they won't back that unless I do a full restore, which would wipe my disk of all the software I've spent the last couple of weeks configuring. Is there anything else I can try? Other than just buying another webcam, I mean. Any suggestions would be appreciated.

• What kind of server do I need to handle 10 million requests and mySQL queries a day?

  - by Calvin

  I'm a new bie of server administration and I'm looking for a powerful hosting service to host my new website. This website is basically a back-end of an mobile online game, and it will: handle up to 10 million of HTTPS request and mySQL queries a day store up to 2000 GB file on the hard disk transfer probably 5000 GB data in and out per month it runs on PHP and mySQL have 10 million records in mySQL database, for each record there are 5-10 fields, around 100 bytes each I really don't know what kind of a server I need to handle these requirements, my question is: what cpu/ram do I need for a dedicated server or vps? what hosting companies are able to offer this kind of dedicated server or VPS? what about cloud computing? I've researched Amazon EC2 but it seems complicated to me. And I've contacted Rackspace but strangely they said Cloudsites is not suitable for my requirements. I wonder if there is other cloud hosting company. any other alternative method? thanks very much!

• Graphing services using pnp4nagios

  - by Matias

  Hi! I've managed to install pnp4nagios 0.6.3 and I'm a bit confused about how pnp4nagios generates graphics. Almost out of the box, it started graphs for ping and some http servers (not all of them). But, how can I make it graph things like disk utilization (When that value comes from SNMP)?? For example, ls /usr/local/pnp4nagios/var/perfdata/isis/ Cola_de_Mail.rrd Cola_de_Mail.xml HTTP.rrd HTTP.xml PING.rrd PING.xml Those are checks running on the host isis, but there are many other checks for that server that are not taken into account by pnp4nagios. How can I make pnp4nagios "see" the other checks?? Thanks!

• Unable to open attachment in Windows Live Mail 2011 (Build 15.4.3502.0922)

  - by Anon2010

  I use Windows Live Mail 2011 (Build 15.4.3502.0922), in Windows 7 Pro 64. When I receive an email message that has an attachment, when I double click to open this attachment, nothing happens. Any kind of attachment, nothing happens. If I right click and choose "Open", nothing happens either. If I right click and choose Save As, I can save the file to disk and open it via Windows Explorer. I would like to be able to double click to open the attachment. I tried to repair WLM but that didn't make any difference. My antivirus is Microsoft Security Essentials. Does anyone know anything about this issue? Thanks

• Video acceleration problem with Windows 7 games and PPTX files

  - by Jordan 1GT

  I have a Dell xps M1330 which originally ran Vista, but I upgraded to Windows 7. When I try to run a Win 7 game like spider solitaire I receive the following message: The game is running in software rendering mode. Hardware acceleration is either disabled or not supported by your video card driver which could slow down game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on. I confirmed that hardware acceleration is turned on. When I go to Dell's site, I'm told there is no later video driver. When I run the game it runs very choppy. I have a .pptx file which is doing strange things in normal view and I suspect it may be related to the same video acceleration problem.

• Virtual fiber channel HBA in Solaris

  - by Phil

  We are trying to set up some virtual Fibre Channel HBA's in Solaris. This seems to be possible with NPIV. Creating NPIV's in a Solaris global zone works fine, but passing that NPIV to a zone didn't work at all. We tried to pass the NPIV as following: # zonecfg -z zone1 'info' zonename: studentz1 [...] device: match: /devices/pci@0,0/pci8086,25f9@6/pci8086,350c@0,3/pci1077,140@4/fp@1,0:devctl allow-partition not specified allow-raw-io not specified Wat we want to do is, set up an environment for SAN exercises. We don't have a physical host per student, so we try to virtualise that in some way (Solaris zones or VMware). It should be possible to display the WWN of the virtual HBA and mount the storage presented by the disk subsystem. Any ideas to pass the NPIV to a solaris zone or to virtualise this with vmware?

• NFSv3 Asynchronous Write Depends on Block Size?

  - by Joe Swanson

  I am trying to figure out if my NFSv3 deployment is performing SAFE asynchronous writes. I suspect that it is doing strictly synchronous writes, as I am getting poor performance in general. I used Wireshark to look at the 'stable' flag in write calls, and look for 'commit' calls. I noticed that, with especially large block sizes, writes to appear to be performed asynchronously: dd if=/dev/zero of=/proj/re3/0/zero bs=2097152 count=512 However, smaller block sizes appear to be performed strictly synchronously: dd if=/dev/zero of=/proj/re3/0/zero bs=8192 count=655360 What gives? How does the client decide whether to tell the server to perform writes synchronously or asynchronously? Is there any way I can get smaller block sizes to be performed asynchronously?

• SQL Server 2005 Default Backup Plan

  - by tylerl

  I noticed that a newly imported database on SQLServer 2005 had configured itself (without my knowledge) to perform daily backups; but it's not deleting old files and quickly filling up the disk. I don't know how the backup job got configured (maybe that's something that gets transferred when you move a database?) but I'm having trouble modifying it. The backup runs as part of SQL Server Agent job called "Daily Backups". This job runs a package called "(SSIS Packages)\Maintenance Plans\Backup Plan" -- which I can't find. The "Management\Maintenance Plans" area for my server is empty. I imagine I could delete the existing plan and re-create it manually, but I was hoping to just modify what was already there, since all that's missing is deleting old files.

• .NET Framework 4.0 installation is very slow

  - by Dimitri C.

  On my Windows Vista, it takes a full 12 minutes to install the .NET Framework 4.0. a) Is this normal? b) If not, can something be done about it? The reason I'm concerned about the speed is because it slows down the testing of our product installer considerably. Testing an installer is time consuming already, but this new .NET Framework installer makes it almost undoable. Detail: I did the test on a clean Vista inside a VirtualBox virtual machine. This setup does not show any performance issues in other situations. I tried both dotNetFx40_Full_x86_x64.exe and dotNetFx40_Client_x86_x64.exe. They both take approximately the same time to install.

• How do I know if my SSD Drive supports TRIM?

  - by Omar Shahine

  Windows 7 has support for the TRIM command which should help ensure that the performance of an SSD drive remains good through it's life. How can you tell if a given SSD drive supports TRIM? See here for a description of TRIM. Also the following from a Microsoft presentation: Microsoft implementation of “Trim” feature is supported in Windows 7 NTFS will send down delete notification to the device supporting “trim” File system operations: Format, Delete, Truncate, Compression OS internal processes: e.g., Snapshot, Volume Manager Three optimization opportunities for the device Enhancing device wear leveling by eliminating merge operation for all deleted data blocks Making early garbage collection possible for fast write Keeping device’s unused storage area as much as possible; more room for device wear leveling.

• Running Windows without administrative rights?

  - by overtherainbow

  Hello, Among the millions of applications written for Windows, I assume there are probably quite a lot that are too old or too sloppy to run without administrative rights. To convert users to using non-admin accounts in their day-to-day use of Windows, I need a tool that will sort applications between those than can run safely as non-admin and those that expect to have those rights and will thus show some obvious or not-so-obvious wrong behavior as a result. Does someone know of such a tool that would be available for XP/Vista/7, and either scan the whole disk for unsafe applications, or would be started at boot time and lurk in the background so that it would show a pop-up and report applications that triggered an error because of this lack of admin rights? Thank you.

• Adding a single 300Gb SCSI drive to poweredge 2850

  - by John Steele

  I have a 2850 setup with 3 146Gb drives, two partitions 1 12GB system with server 2003 sp2 and 1 261Gb Data. I am strapped on disk space on the data partition having to push data around. I wanted to add a 300Gb single drive for lesser critical data, is this possible? Or is it best to add 2 300Gb drives for another RAID 1 configuration? This is my church network and while it is mission critical it is not enterprise so I can take it down for a few hours. Any pointers to documentation or direct help would be greatly appreciated. John

• What's the downsides of Running Ubuntu 9.10 32bit on AMD64 Processor

  - by Omar Dolaimy

  Hi, I was thinking about installing Ubuntu 9.10 32bit on a DELL Inspiron 1501 with 64bit processor Laptop. Since It's was real pain to me to run Java Browser plugin, Flash Plugin, J2ME Toolkit, and many other tools. But It was 90% OK with me. This was Ubuntu 8.10 (a year ago), And now the Ubuntu 9.10 came and I'm thinking about installing the 32 bit on it and get rid of the pain. Is there a downside for that?? considering that the display card is not supported now so exclude this from your calculation, I will never play REAL games on it and I'm not a big fan of Compiz effects. I'm not here to ask about the performance (which is about 15%+ for the 64bit only), I just want compatibility!

• Troubleshooting Windows Server 2012 storage spaces

  - by Iravanchi

  I'm trying the new "Storage Pools" feature on Windows Server 2012, and I've created several disks on the pool. When I restart the server, some of the disks (two, out of four) do not attach automatically, and don't show up in the list of disks. I can go to Server Manager File and Storage Services Storage Pools, and the faulty disks are listed with a yellow triangle beside them. The drive health in the properties are "unknown". But if I right-click and choose attach, the disk comes online, with all the content on it intact. But after another restart, it's the same story. I didn't find any relevant event in the event log, how can I find out why the drives are not attaching?

• P2V - Cold Clone ISO

  - by jlehtinen

  I need to cold clone a physical box in a VMWare environment. What are people using for this these days? My preference is for VMWare's vConverter ISO, but it appears that this was discontinued. It's no longer available for download on their site from what I can tell (even under old versions). I found one guy who appears to have an ISO for version 3.0.3 of vConverter posted to his site for download, but I'm eternally skeptical about downloading these types of software from random strangers: http://thatcouldbeaproblem.com/?p=584 I also found some mention of using MOA, but I've never used this and have no idea on how effective it is as a vConverter replacement. http://www.sanbarrow.com/moa.html One other options seems to be using Acronis - booting off an Acronis disk to capture a .tib, then using a standard installation of vConverter to push the .tib to ESXi.

• Will more memory help my CPU-peaking SQL Server 2008 R2

  - by Tor Haugen

  I'm supporting a system running against a SQL Server 2008 R2. The server is a single-CPU box with 8 GB of memory. As traffic has increased, the server has started saturating, peaking to 100% CPU ever more often. Disk I/O remains moderate (somewhat surprisingly). Obviously, a new server would be the best option. But failing that, can I expect a noticable improvement from installing more RAM? Or does RAM only help for I/O issues (through caching)?

• How to benchmark apache/nginx setup

  - by Saif Bechan

  I am planning to setup nginx as reverse proxy. I will have apache to deliver my dynamic content, and nginx will deliver the static content. My configuration i have now is just Apache with fastCGI. This gives me no configuration problems and runs great. After I have set up nginx I want to run some benchmarks to see if I really got some performance increases, else i will switch back. Does anyone know how I can benchmark this type of setup? Or maybe someone did this already and have some canned results, I will be glad to hear them.

• How to Shrink large Hyper-V VM

  - by autrevo

  Using Disk2VHD utility I converted my bare-metal OS into Hyper-V VHD - http://technet.microsoft.com/en-us/sysinternals/ee656415.aspx And I could obtain a huge 190GB VHD file. Apart from performance issues, this VHD worked fine as guest when hosted on Windows Server 200 R2, Hyper-V. Having realized need to keeping only system files and application installations on VHD. I have deleted most of the junk data from this VHD and now it contains only 20-25 GB. But I am not able to shrink the VHD VM. Having done some research, I came to know, this as a limitation of .VHD files. Subsequently I followed these two step using Edit Virtual Hard Wizard on Windows 2012 Box. Convert from VHD to VHDX (took close to 3 hrs.) Compact (Another 4 hrs.) This did not ever shrink the VHDX either. Does Hyper-V does not provide proper support to handle large VHDs or VHDXs whose size are the range of 200GB.

• Xen and HyperVM build question on os template

  - by Levi De Haan

  I recently built a server with hypervm and xen, now i know xen from command line, but hypervm ties into our whmcs and so its a requirement, however my question is this, when i build a new o/s template my partition table is gone, and i know why, but i was wondering if anyone has built anything in hypervm for adding in partition tables, so i dont have to reinvent the wheel :). i can do it command line in the created vm with fdisk, and i have tracked down the creation scripts for hypervm but i am unsure if these insert directly into the machine as it looks like a lot of the things it does are externalized and are for xen to assign things like ip address etc.. oh and on an aside when i go in to modify the .cnf file to change the boot disk from cdrom to drive on windows when i boot using hypervm it overwrites my setting again..frustrating as heck, i've been trying to track down where in the code it does this, has anyone else had this problem and if so how did you fix it if you did?

• Is there such a concept as "dead thumbnails" in Windows?

  - by Pacerier

  I realised that in disk cleanup (cleanmgr.exe) there is an item "Thumbnails": Windows keeps a copy of all of your picture, video, and document thumbnails so they can be displayed quickly when you open a folder. If you delete these thumbnails, they will be automatically recreated as needed. I was pondering about why there is even an option to delete the thumbnails. Is it true that there will be "dead" thumbnails (for example if I delete a folder that has a thumbnail and the folder is deleted but the thumbnail still exists) so this option is used to clean "dead" thumbnails?

• Converting a VMware player image from non-persistant to persistant

  - by Journeyman Geek

  I'm pondering setting up a virtual machine to generate app-v (since i got mdop from school) or thinapp application virtualisation packages. Ideally with either of these, i should work off a fresh system do the install, then copy out the packages produced. I'd like to not have to reinstall windows per package to get a fresh, unmodified stock copy of windows. I'm aware that its possible to make a hard disk image persistant in vmware player (one of my lecturers did it, but he's in another country). I'm wondering how would i convert a persistant image to a non persistant one? I'm currently running vmware player 4, with windows 7 guest and host.
