  • Identify SATA hard drive

    - by Rob Nicholson
    Very similar question to: Physically Identify the failed hard drive But for Windows 2003 this time. Scenario: Four identical SATA hard drives plugged into motherboard (no RAID controller here) Configured as single drive in Windows as a spanned volume One of them is starting to fail with error "The driver detected a controller error on \Device\Harddisk3" How do you cross-reference Harddisk3 to the physical SATA connection on the motherboard so you know which drive to replace? I know replacing this drive will trash the spanned array requiring it to be rebuilt anyway so my rough and ready solution is: Delete the spanned partition Create individual partitions on each drive labelled E: F: G: and H: and work out which one is Harddisk3 Power down, remove each disk one at a time, power-up until the drive letter disappears But this seems a rather crude method of identifying the drive. The SATA connectors will be numbered on the motherboard but I appreciate this might not cross-match to what Windows calls them. Thanks, Rob.

  • Home server - HP Proliant Microserver - Software and setup - OS on USB stick? [closed]

    - by Lloyd Watkin
    I've just purchased a HP ProLiant Microserver for home use. I want to set up with web server, samba shares, the usual stuff. My question is really about system setup. It has an internal USB socket so I've attempted to install a copy of Fedora 14 onto it. I turned off X/Gnome, but it still ran like a pig. I've now put the OS on one of the internal disks (250Gb, 7200rpm), but I was wondering if there was a way to utilise the internal USB to give me better power-saving allowing the hard drives to be shut down when not in use. How would you set this server up? I'd rather not go to the extra cost of an SSD right now, but if that's the best way then so be it.

  • How to erase a SSD to restore factory performance in Linux?

    - by Andy B
    Due to big performance issues with an mdraid-1 array I'd like to pull down from the array one of the devices (Samsung 840 Pro), erase it to restore factory performance and re-add it to the array. The reason I want to do this to one of the SSDs is because the poor performance seems to be related to one specific SSD out of the two (although they are the same brand, model and firmware ver). But how do I erase a SSD from Linux? I mention that hdparm indicates that both drives are frozen at this time. Maybe because they are part of an md array? Thanks in advance!

  • an error while restoring windows 7 from a restore point

    - by user178231
    When I make a restore point and I come back to restore the windows 7, it gives this error: No restore point have been created on your computer system drives, to create a restore point open system protection. I've made a restore point why does it give this error? What should I do? I completely know how to make restore points and I've made some on the laptop and other devices but in my computer which have windows 7 when I make restore point and when I want to use them it gives the error! Please help. I'm not English so can't speak it well.

  • Intsalling Linux on PowerEdge R410 via USB

    - by Bill Johnson
    I’m hoping someone can help me with the following issue. I have a Dell PowerEdge R410 and basically the Optical Drive has failed when I have been given the server. I have installed 2 SATA drives and want to install Ubuntu 11.04; however, each time I have tried i.e. using bootable .iso on USB it failed. I assume it's failing as with a lot of releases they all look at the CD drive. Ubunutu has failed on installation with the error message unable to mount CD. I have tried installing Microsoft Hyper-v and that also fails as during installation it asks for CD/DVD drivers. Tried embedding ISO's from various distro's (Linux and Windows) with drivers and that hasn't worked out either. Does anyone have any idea on how I can get Ubuntu on this server? Should I look towards an old distro perhaps?

  • Planning to buy a server with at least 48GB Ram, are the blades way to go?

    - by varchar1
    We're planning to host our website for the first time for ourselves. We have currently have a linode of 8 gigs and the memory is going up to 90% most of the time. So I want to move my website to my own server with huge RAM. So this will be first time to manage any physical hardware of a server. So I came across IBM's BladeCenter, found them interesting. So can I just buy the blade and run it? Or do I have to buy the chassis for sure? Also, do I need to buy an UPS? So how hard is it to setup? How about the hard drives? Can I setup them easily? Please advice.

  • suggestions for migrating a windows 7 install to a new 4K sector disk

    - by myCubeIsMyCell
    Hi, I'm looking to upgrade the disk on a windows 7 box to a new larger drive. In the past for such migrations I'd just hook both drives up and use a linux boot disk and use dd to copy from one disk to the next... boot up the new drive & expand the partition. The drive I just purchased however is a western digital using 4k sectors... not sure if there'd be any complications using my old method moving from a 512b sector drive. Current plan is to try the migration by doing a win7 system image backup to an external drive... then restore the image to the new drive via system restore boot disk. Any suggestions or recommendations on how to best complete this migration would be greatly appreciated. Thanks!

  • Finding optimal ddrescue command line options where Accuracy > Speed

    - by gav
    I'm read up a bit about this tool and obviously looked at the man pages. The trouble is that ddrescue takes so long I need to get the command right first time. I wasn't sure how to improve on the vanilla; $ sudo ./ddrescue -v /dev/disk0s5 MyVolImage.dmg MyVolRescue.log $ sudo ./ddrescue -v MyVolImage.dmg /dev/disk1s3 MyVolRestore.log From HSF+ to HSF+ drives Source (Broken) HDD is connected via USB 2.0 Dest HDD is inside MacBook I would choose accuracy over speed There seem to be a lot of options but I'm not sure how they impact quality and speed of recovery. Thanks, Gav

  • Using off-the-shelf hardware for brand-name servers; Possible? Good idea?

    - by threecheeseopera
    Is it possible or advisable to use 'regular' not-sanctioned-by-the-server-manufacturer hardware in high end servers? Often these manufacturer-supplied parts have a very high price markup, and I wonder if it's always necessary (understanding that they probably apply more rigorous requirements to this hardware). For example, Dell sells 300GB 15,000rpm serial-attached scsi drives for a certain server family for almost $600 each, while newegg sells a drive with the same specs for almost half the price http://www.newegg.com/Product/Product.aspx?Item=N82E16822116059. Do we really need to pay these high markups, especially for disks that are likely RAID-ed and so guarded against catastrophic failure?

  • How to speed up apache

    - by Zen_silence
    We have a server with 8Cores, 16GB of RAM and RAID 0 SAS 10K drives. Our goal is to use this to serve a fairly simple php application quickly. We have tested all other components and we think we have narrowed it down to apache is our bottleneck. I am no apache guru I have done some research and tested a couple things but when i test with JMeter launching 100 concurrent connections against the server the first 10 - 20 come back quickly 30 - 100ms but the rest take between 1000ms to 3000ms. Anyone have any ideas on what to change in our apache config to make this faster right now its a vanilla install of apache.

  • How to configure autofs5 timeout on per-filesystem basis?

    - by Norman Ramsey
    Because of a show-stopping bug in Debian autofs 4, I just upgraded to autofs5. It is not honoring the timeout option in my auto.master file: /var/autofs/removable /etc/auto.removable --timeout=2 I use this map for thumb drives and so on; I don't want a general default timeout of 2 seconds. I did some digging and although the --timeout option worked in autofs 4, and it appears in some examples on the Web, it is not actually sanctioned (or even mentioned) in the documentation for the auto.master file. So I don't feel I can report the problem as a bug. How can I get autofs5 to timeout after 2 seconds only on designated filesystems? Update: I am using a Debian-packaged autofs5, version 5.0.4-3.2.

  • Windows 8.1 installation: Which drive is the F drive?

    - by sammyg
    I am doing a clean install of Windows 8.1 on an old PC. It was purchased as download from Microsoft Store and written to and booted from a USB flash drive. It went through all of these steps: Copying Windows Files Getting files ready for installation Installing features Installing updates Then at "Getting finished" I am stuck at this stupid dialog box. Please unplug the following external drive and click OK to restart your computer and finish installing Windows. F: How do I tell what physical drive this is? Can I drop to command prompt during installation? And is it safe to unplug it while powered on? There is no external hard drive connected, none that I can see. There is no USB or FireWire drive connected externally. I think it sees one of the internal drives as external... in some weird way?!

  • Any way to know what files were in a broken ZFS pool?

    - by Erik Tjernlund
    I have a large ZFS pool of 4 combined drives. Now, the filesystem can not be mounted: pool: tank state: UNAVAIL status: One or more devices could not be opened. There are insufficient replicas for the pool to continue functioning. action: Attach the missing device and online it using 'zpool online'. see: http://www.sun.com/msg/ZFS-8000-3C scan: none requested config: NAME STATE READ WRITE CKSUM tank UNAVAIL 0 0 0 insufficient replicas c10t0d0 ONLINE 0 0 0 c8t0d0 UNAVAIL 0 0 0 cannot open c8t1d0 ONLINE 0 0 0 c10t1d0 ONLINE 0 0 0 Probably a broken drive (c8t0d0). I'm not overly concerned by the loss of the data, but I'd love to know exactly which files were in that pool. Is there any way to get a listing of what files were there?

  • How to store 250TB of data and develop a backup/recovery plan?

    - by luccio
    I'm really new to this topic, so big apology for stupid questions. I have a school project and I want to know how to store 250TB of data with life-cycle for 18 months. It means every record is stored for 18 months and after this period of time can be deleted. There are 2 issues: store data backup data Due to amount of data I will probably need to combine data tapes and hard drives. I'd like to have "fast" access to 3 month old data, so ~42TB on disk. I really don't know what RAID should I use, or is here any better solution than combining disk and data tapes? Thanks for any advice, article, anything. I'm getting lost.

  • Page File - Why set one for each drive?

    - by Magic
    Hello, I have Windows Vista Business Edition running on my laptop (brand is HCL). I have 4 HDD which are as follows - C - 29.2 GB (of which only 3.68 GB is free) D - 39 GB (of which 37.8 GB is free) E - 39 GB (of which 37.3 GB is free) F - 41.6 (of which 41.4 GB is free) However, my page file settings are as below. Automatically manage paging file for all drives. Question - Why should I set one for each drive? Should I set my page file on the OS Root Drive. I happen to talk to a System Administrator in an IT company and he advised that we should never set the page file on the OS drive but on an alternate drive wherever possible. It would be really helpful, if you can guide me here or at least point me to the right resources so that I can read about paging and best practices of paging. Cheers,

  • Is there a way for Windows 7 to show remaining disk space in the status bar?

    - by Matt Thompson
    This is really driving me nuts. I do a lot of moving media files to and from USB drives, and I am constantly looking to the status bar to see how much remaining space I have on a drive. It's quick, and doesn't involve any clicking. At least, that's what I used to do using Windows XP. Is there a way to get the status bar in Windows 7 to behave in the same way? I saw in a Wikipedia article that some features have been removed from Windows 7, including these two that seem to be affecting me the most: The size of any selected item and free disk space are not shown on the status bar. When no items are selected in a folder, neither the details pane nor the status bar show the total size of files in the folder. Are there any plug-ins or registry tweaks that can be made to return this functionality? If not what is the quickest way to get the remaining space on a drive without having to click on something and leaving the directory you are working in?

  • HP DL380 G5 Predictive Drive Failure on a new drive

    - by CharlieJ
    Consolidated Error Report: Controller: Smart Array P400 in slot 3 Device: Physical Drive 1I:1:1 Message: Predictive failure. We have an HP DL380 G5 server with two 72GB 15k SAS drives configured in RAID1. A couple weeks ago, the server reported a drive failure on Drive 1. We replaced the drive with a brand new HDD -- same spares number. A few days ago, the server started reporting a predictive drive failure on the new drive, in the same bay. Is it likely the new drive is bad... or more likely we have a bay failure problem? This is a production server, so any advice would be appreciated. I have another spare drive, so I can hot swap it if this is a fluke and new drive is just bad. THANKS! CharlieJ

  • FDE with DiskCryptor V1 (TRIM Support) on Crucial M4 SSD on W7 x64 - Unpartitioned Space?

    - by JamesM
    I have a new Alienware m11 laptop with a brand new Crucial M4 128GB SSD. I have installed the SSD but not used it yet. I am thinking of using FDE with DiskCryptor 1.0.732.111. I will install Win7 Pro x64. I have read about support for TRIM in v1.0.732.111 but also about leaving unpartitioned space. My SSD drive, 'Crucual M4' does not have a manufacturer built-in reserve like other drives. My questions are: Should I leave some free unpartitioned space with v1 of DC and W7x64 even though it will support TRIM or should I not do this? Should I install DC v1 first or after installing Windows 7 (assuming it is brand new, never been used SSD)?

  • Is it safe to run an operating system from an USB flash drive?

    - by Georg
    I've got a laptop that has a broken harddisk controller. Replacing the motherboard is quite expensive. I thought about buying a flash drive and installing & running the system from it. However, I'm concerned about some things. Speed: Are they fast enough for swap memory (I've got only 1GB RAM installed.) I'm considering buying 2 or 3 of them and making them into a RAID. What about limited write cycles? How long will it last for a system that has a filesystem with journaling enabled? I'd hate to abandon it. Are there significant differences between internal SSD which are used in modern laptops like MacBooks and USB flash drives? What should I expect in 10 years when the memory wear starts kicking in?

  • Is defragging right for me?

    - by blade
    Hi, I am using Hyper-V on my Windows Server 2008 R2 DC x64 machine. I am also using standard SATA drives. I read some threads on here about defraging but could not reach a conclusion about whether or not I should use defragging. Can anyone shed some light on whether this will be right for me? Furthermore, what tool is best? There seems to be 3: http://www.perfectdisk.com/products/business-perfectdisk11-server/key-features http://www.diskeeper.com/diskeeper/home/server-edition.aspx?id=40279&wid=7 http://www.perfectdisk.com/products/business-perfectdisk11-hyper-v/learn-more Anyone have experience with this?

  • Home Server restore fails cannot find boot device

    - by Tim Heuer
    I am using Windows Home Server to backup my PCs. I recently had a hard drive failure on one of my WHS connected PCs and obtained an identical sized/speed drive for my laptop. I used the latest home server restore CD and did the restore. It said it completed successfully. Upon reboot, it says 'cannot find boot device' and lists all my drives (hard drive, cd, network book) indicating no valid operating system was found. I boot using the Win7 repair disk and while it doesn't see the operating system, it sees the drive and if I go into a command prompt, I can see all my data on the drive. My laptop is Windows 7 64-bit Ultimate. I've tried most everything I can think of. I'm a technical user (software developer) so I'm pretty aware of how things work (or should). I don't feel like I'm missing a simple step here.

  • Can't create a new HomeGroup in Windows 8

    - by Ian Smith
    I'm trying to create a new HomeGroup in Windows 8 for 2 new PCs with Windows 8 installed so that I can share printers etc. Both PCs use Microsoft Account to log in - a Microsoft Account I set up about a year ago with one of the early beta's with a PC that's since been repaved with the RTM of Windows 8 When I click on "HomeGroup" in the "Metro" control panel the "Create" option is not there. Instead I'm told that "HomeGroup" already exists on the PC I've since repaved and renamed and I can join it by entering the password. I have no recollection of what the password might have been and in any event that PC doesn't exist, but there is no way to say "That group doesn't exist anymore just create me a new one dammit". Even using the old Control Panel the "HomeGroup" nonsense persists with the only option being "Join" that needs a password. How do I "start afresh" and create a new HomeGroup that I can use to connect my Windows 8 and Windows 7 PCs and use common printers, network drives etc.

  • replacement drive cage for power edge R710

    - by bumble_bee_tuna
    Hi I'm performance tuning a DB server its a Dell R710 there is a very significant I/O bottleneck. Unfortunately the server was purchased with the 6 x 3.5 inch sata configuration which doesn't give me the leeway I need to address the issue. Before going to DAS does anyone know if it is possible to purchase a replacement front drive enclosure ? I know the server is configurable with something like 12 or 16 2.5 inch drives and it appears to be modular ? I tired contacting dell but the offshore parts department reps are not very bright lol. Thanks.

  • This is probably a horrible idea; putting a Mac Mini in a mini-fridge [closed]

    - by Christian A. Strømmen
    Possible Duplicate: Putting servers inside a refrigerator? Just moved to a new house and had to place my Mac Mini server in the attic. Now this is really nice and cool at this time of the year, but during summer it's going to get blistering hot up there, meaning I have to find a solution that won't kill my Mac Mini and the two WD external drives I have connected to it. Is there any good reason why I couldn't just buy a mini-fridge and put them inside that? The only thing I can think of is condensation building up, but I have no idea if that will be an issue or not. Something like this. And yes, I'm pretty sure this is a terrible idea, but I figured it was worth mentioning here and getting some feedback. What other options are there?

    Hardware: MBP early 2011 version OS: Mountain lion App: Xcode 4.5.2 Problem: Every time when I start Xcode, 2 or 3 processes called "git" start running. But when I quit Xcode the "git" process won't quit and are still using a lot of CPU. Then the computer becomes quite hot and the battery gets drained very quickly. If I manually kill these processes the problem is gone. I tried to reinstall Xcode several times but the problem comes back every time. It drives me crazy. Any help will be appreciated!
