• Deleted entire harddisk. Now my laptop won't boot anything and stuck at grub rescue

  - by Jahan

  My laptop is Dell Inspiron N4030. I used to use Ubuntu 12.04 and it was on the entire hard drive. I tried to install windows 7 but my laptop couldn't install it. So, I decided to delete the entire hard drive and do a fresh install of Windows 7. But after deletion I immediately removed the gparted live usb which I was using to delete the partitions of my hard drive. And then tried booting from windows 7 cd, didn't work, tried ubuntu live cd, didn't work, tried hiren's boot cd, didn't work, tried super grub disk, didn't work. Probably I'm not doing it right. Help needed badly.

• Raid on ICH9R chip set

  - by user500982

  Hi Im looking at buyign this MB: http://www.supermicro.com/products/motherboard/ATOM/ICH9/X7SPE-HF-D525.cfm Im wondering though if the chipset will support the raid configuration I need. Im looking to configure the following arrays: raid array 1: 2 2TB Disks in Raid 0 raid array 2: 2 2TB Disks in Raid 0 raid array 3 (not actualy an array): 1 300GB Disk not in raid, to be used for OS and boot. So in total there would be 5 drives and the board supports 6. so im good when it comes to connections. However I have herd some chip sets only support one raid array (volume). so either all drives are individual, or are in the array. I must have 2 sperate raid arrays independent of each other, and a 5th drive not in any array. Anybody know if this setup will work? Thanks, -Stewart

• How to find spyware dll launched using svchost.exe

  - by Sheen

  This weekend I found my PC was possibly infected by some virus or spyware. There is one "svchost.exe -k netsvcs" in my task manager, and it is running under my user name, rather than SYSTEM accounts. There is already another same process with same command line options under SYSTEM account. This user account svchost.exe consistently consumes 50% CPU (1 of 2 cores of my CPU). In Process Explorer, I can see it is started by explorer.exe, instead of services.exe. However, I failed to find its real service dll place in registry or disk. Does anyone know how to find this malicious program?

• How to determine non-movable files in Windows 7?

  - by David

  Is there a way to determine which unmovable files are preventing Shrink Volume from releasing the full potential free space? Background: I have a 90 GB partition with Windows 7 on it, and 60 GB free space. I want to shrink it down to about 40 GB, and use the reclaimed 50 GB for a separate data partition. The Shrink Volume tool in Disk Management is only willing to give me 8 GB back. My understanding is that this is because of immovable files. I've followed the instructions found here, which involved disabling hibernation, pagefile, system restore, kernal dump, making sure all related files were deleted, and defrag'ing. I have successfully followed those same instructions before on this same drive, and partitoned the original 150 GB space into 90 GB and 60 GB, but I'm not so lucky this time.

• My WD passport detected but not shown on my computer

  - by Rakesh Patel

  1TB WD harddisk is detected in laptop but drives not visible on my computer. Under disk managment drives shown without letters. Right clicking on these drives give 2 options: Delete volume Help. The same harddisk was running well on the same laptop a day before. It is also showing full size of hard drives, Healthy (Primary Partition) etc. (this happened after harddisk usage by guest). Harddisk is new only (about 5 month usage) Please suggest: Is there hardware related problem inside harddisk, if so is it repairable? Is there any option to recover data?

• Can't mount home after trying to resize (bad geometry: block count exceeds size of device).

  - by Lynn

  This is on a fresh computer (super computer actually). It got to me with 15T on the home mount and 50G on the root. I tried allocating 7T to root and resizing (since I'm putting a local yum repo on this machine as it has no internet access nor will it ever). I tried following the instructions here: Centos 6.3 disk space allocation but something went wrong and the home won't mount again. Instead I get from dmesg | tail: EXT4-fs (dm-2): bad geometry: block count 4294967295 exceeds size of device (1342177280 blocks) df -h nets this output: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root 7.0T 3.6G 6.6T 1% / tmpfs 190G 216K 190G 1% /dev/shm /dev/sda1 485M 38M 422M 9% /boot I didn't have any files on /dev/mapper/VolGroup-lv_home. Will simply running mke2fs fix it to be mountable? What sort of options should I run it with. I've never resized volumes before or used mke2fs. I don't want to make this mess worse.

• Intel RAID0 on Windows 8 not Displaying Correct Media Type

  - by kobaltz

  I have my primary C Drive which consists of 2 Intel 120GB SSD Drives in a RAID0. I have a clean install of Windows 8 Pro, latest MEI software, latest RST software, latest Intel Toolbox. Prior to this I had installed Windows 8 Pro as an upgrade. When I went into the Optimize Drives while in the Upgrade installation, it showed the Media Types as Solid State Drives. However, now since I am in a brand new install, it is showing the Media Type as Hard Disk Drive. I am worried about this because of the trim not working properly. Before when in the upgrade, it showed SSD as the media type and the Optimize option would perform a manual trim. Unfortunately, my search credentials on Google are so common to many other things (ie Raid0, SSD, Windows 8, Media Type) that all I am finding are useless topics. Before, (found on random site) it showed the Media Type as below

• Dummy SMTP server as a service

  - by levidos

  I have a Windows Server 2008 machine with IIS installed which is hosting a webapp that is sending some notification mails once-in-a-while. What I'd like to do is to monitor the email sent by the application. For this I need a dummy SMTP server which intercepts messages but won't send them further but save them locally on the hard disk. I've already found some of them like Papercut, SMTP4Dev. The problem with these that I have to be logged on the server all the time which is not suitable because the server has only 2+1 TS connections. I like to run a program like these as a windows service and check the mails when I need them.

• What's the best encoding for videos on the Zune?

  - by Will

  I've got videos I want to encode to put on the zune. Have the encoding software (using Expression Encoder), but I'm not sure about what I should transcode to. I used the settings built into EE for the Zune, but the sync software still shows these videos are being converted before sync. I already have to get these videos into an acceptable format, so encoding twice is a waste of time and space. What I'm looking for is a video codec, audio codec, bitrate, WxH, and anything else I need to encode a video so it goes straight from my disk onto my Zune without re-encoding.

• Feeding the kernels entropy source from other machines and/or increasing its maximum size

  - by David Spillett

  We have has a little trouble with a small box that acts as a VPN end-point and mail relay for our network, caused by the available entropy for /dev/random being too low (which causes TLS connection attempts by exim to fail). The machine doesn't do anything else, so the normal feed into the entropy pool (interrupt timings from things like disk access) is not enough. As a quick hack I've set a looping script that reads from /dev/hda at a couple of Mbyte/sec which keeps it topped up. Other than buying a hardware RNG, is there a clean way of piping data for entry from elsewhere, such as a copy of the data our file server uses for its entropy source? I've spotted several tips for using rng-tools to feed it from /dev/urandom on the same machine but that "feels dirty". Also, is it possible to increase the maximum pool size? It currently seems to max out at 3585.

• misaligned raid partition in Ubuntu 10.04

  - by Linux Jedi

  I attached two identical hard drives to my linux machine. Then using gparted I formated the first 1024 mb at the beginning of each drive as linux swap space. Then I went into system-administration-disk utility. In there I went to file-create-RAID array. I selected the remaining space in each of the two identical hard drives and created a striped raid array. After the array was created, a warning message appeared. It said "The partition is misaligned by 522240 bytes. This may result in very poor performance. Repartitioning is suggested." What do I do now? As far as I can tell, the partitions are identical.

• Taking an image backup of an entire server?

  - by WarDoGG

  I am currently using a dedicated server for my hosting needs. However, the costs are too high and I would like to suspend everything until I work out my business strategy again. Is there a way I can take a complete backup of the filesystem and run it in VMWare ? I cannot just copy the entire filesystem because there are lots of tools installed and tight changes to the server configuration files I myself dont know about (by the developers), but I need a snapshot of the entire disk image along with processes installed and everything is as is because for development needs, I need to work on this copy in VMWare or VirtualBox etc. Is it possible for me to take a full image copy ? How do I do it ?

• One hard drive missing after converting from ide to ahci

  - by user700859

  I have two 500GB SATA HDD in my desktop running XP. After converting from IDE to AHCI, the HDD I use to store data can no longer be accessed from XP. It shows only the first partition as 150GB, and data type is listed as RAW. However, if I boot into a live linux environment or if I pull that HDD out and connect it using USB, I can still get to all my files again. So I completely formatted the HDD into one single partition. But XP still does not recognize it. It still shows the disk as the 150GB partition and data type is still RAW. What's going on and how do I fix this? Thanks in advance.

• How do I make the Windows low memory warning less sensitive?

  - by Stephen

  I keep getting this annoying low memory warning/prompt to close games I play. It happens very often and I still have ~6 gigs of ram free. I disabled virtual memory because it was putting stuff on the pagefile when I had 10 gigs free ram so that spiked my disk usage. Is there any way to disable this warning? I have 16GB ram so it shouldn't be an issue. I would prefer to keep pagefiles off because my HD is very loud so it's nice to keep it spun down as much as possible. I don't want to disable it completely. Ideally, I would like it to go off when I have ~2GB left rather than 6, but if this isn't viable, I may just disable it completely.

• Solution to Manage and Monitor (Ubuntu) Machines

  - by Elmar Weber

  I'm looking for a tool like Canonical (system management and monitoring for Ubuntu) that is Open Source and free. The goal is to manage a dozen or so KVM machines for private testing purposes. I know of puppet and munin or RHQ as separate tools to manage and monitor, but I'd prefer something integrated. Any tips? Basic requirements would be: system package management and update (individual selection for each managed node) configuration of basic system services (Users, NFS, cron, ideally also Apache) monitoring (charting of system resources, disk, io, memory, etc) and alerting, ideally a default configuration with sensible values for alerts

• Text template or tool for documentation of computer configurations

  - by mjustin

  I regularly write and update technical documentation which will be used to set up a new virtual machine, or to have a lookup for system dependencies in networks with around 20-50 (server-side) computers. At the moment I use OpenOffice Writer with text tables, and create one document per intranet domain. To improve this documentation, I would like to collect some examples to identify areas where my documents can be improved, regarding general structure and content, to make it easy to read and use not only for me but also for technical staff, helpdesk etc. Are there simple text templates (for example for OpenOffice Writer) or tools (maybe database-driven) for structured documentation of a computer configuration? Such a template / tool should provide required and optional configuration sections, like 'operating system', 'installed services', 'mapped network drives', 'scheduled tasks', 'remote servers', 'logon user account', 'firewall settings', 'hard disk size' ... It is not so much low-level hardware docs but more infrastructure / integration information in these documents (no BIOS settings, MAC addresses).

• Search Files (Preferably with index) on Windows 2000 Server

  - by ThinkBohemian

  I have many files on a windows server 2000 machine that is setup to act as a networked disk drive, is there anyway I can index the files and make that index available as a search to more people than just me? Bonus if the index can look inside of documents such as readme.txt? If there is no easy way to do this globaly (for all users) Is there a way I could generate and store an index locally on my computer? If this is the wrong place to ask this question, any advice on community more suited?

• Linux web server shared hosting file errors

  - by dfilkovi

  I'm using a shared hosting to host my website and have some problems with files from time to time. First, one of my file (php) was missing a part of code (nothing to do with hackers just a random piece of code was missing), then after some time a value inside a mysql table was also missing a part, then a whole table column disappeared, after that a whole file on my site disappeared and lastly again some code from a file disappeared, my hosting service says it has nothing to do with them, but this is stupid, how can this happen, no hacker attack could do such a thing, I believe it's some kind of a disk corruption or bad backup. Anyone have any ideas?

• Why has my Mac been running fsck_hfs for two days now?

  - by Nate

  I first noticed that fsck_hfs was running, taking up 50-75% of a CPU, yesterday. It continues to run today. ps shows that it is doing /sbin/fsck_hfs -f -n -x -E /dev/disk3. Only problem: I don’t think I have a /dev/disk3. Why is it running? Will it ever finish? Can I kill it? What is /dev/disk3? Could it be my Time Machine volume, which is not mounted at the moment? System Info: MacBook Pro (2008). It has two disks installed—the internal disk (/dev/disk1) and a PC Card SSD (/dev/disk0, surprisingly). It connects to a remote Time Machine volume attached to an Airport Extreme base station.

• Proper way to connect SATA and IDE Hard drives together?

  - by Bartek

  I have an old IDE hard drive that has a broken Windows install on it. It just won't boot up, and I've tried a variety of solutions. That's fine, I really just need a few files on the hard drive. I have a computer that uses a SATA connected hard drive. It's a working PC. I would like to connect the old IDE hard drive to that compute and basically browse through the file system, grab the files, and copy them to my existing computer. My problem is with my few attempts to connect the IDE drive I would get Boot Disk Failures and so forth. I guess it's trying to boot from the IDE but I'm not really sure. Any help would be appreciated, Thanks!

• VPS hosting for a social network

  - by Jana

  Hi, I've developed a social network and I've been using shared hosting for that since it was launched. With that I wasn't able to send emails in bulk in cases like "newsletters" and "invitations to join my site". Plus most importantly most of the mails I send ended up in user's SPAM list.I'm planning to move into VPS as it may not have limits added. I'm wondering what's the cheapest VPS host available. I'm not pretty much familiar with Linux commands and seeking cPanel to do the work for me. Will the following configuration suit for a "new" social network like mine which has a less load? 1000Mhz Guaranteed 512MB Guaranteed RAM 20GB (RAID) Disk Space 1000GB/month Bandwidth 2 IP(s) & 5 Backups Semi Managed Thanks in advance

• Anybody know how to get podcasts sorted correctly on a Zune?

  - by Will

  If I could understand the logic behind it I could actually manage to get my stuff sorted correctly on the device. It doesn't matter how things are sorted on disk, or in the software itself. As items are added to the sync list they end up sorted in some weird manner which, quite frankly, brings out an anger in me that scares me. A primitive, misshapen and unthinking anger. Kind of like the lumpy guy in Altered States. Frankly, I'm afraid one day its going to burst forth and I will track down the entire Zune team and make them pay for their failures. Help me prevent this from happening. Help me understand what I need to do to ensure my podcasts end up in the order I wish them to be in, not some obscure random order that makes no sense.

• team foundation server 2010 installation from DVD - I get agent installation instead!

  GRRRRRRRRRRRR!(#Y%)@#!! They bragged they now have a very easy installation! I don't get it. I entered the MSDN "Disk 5000: Developer Tools" DVD, opened default.htm, clicked on the "Visual Studio Team Foundation Server 2010" link. The VSTFS2010 folder open. I click autorun.exe. And then I get "Microsoft Visual Studio Agents 2010 Setup". I don't get it. Why "agents"? I wanted to instal a server!

• How to efficiently dump a huge MySQL innodb database?

  - by Jagbir

  I got an Ubuntu 10.04 production MySQL database server where total size of database is 260 GB while size of root partition is itself 300 GB where DB is stored, essentially means around 96% of / is full and there's no space left for storing dump/backup etc. No other disk is attached to server as of now. My task is to migrate this database to other server sitting in different datacenter. Question is how to do that efficiently with minimum downtime? I'm thinking in line of: Request to attach an extra drive to server and take a dump in that drive. Transfer dump to new server, restore it and make new server slave of existing one to keep data in sync When migration is needed, break replication, update slave config to accept read/write requests and make old server read-only so it won't entertain any write requests and tell app developers to update there config with new IP address for db. What's your suggestions to improve this or any alternate better approach for this task?
