• Un-do Windows disk convert HFS+

  - by BLAKE

  Last night, a friend asked my to give him a copy of a word document. He handed me an external hard drive and left. I plugged the hard drive into my file server running Windows Server 2003, opened disk management and clicked OK. (I know that in Windows 2003 you need to manually assign a drive letter to external drives.) I then looked at the drive in disk management and it said that it was unallocated space. I called my friend and he said that there was data on the drive, but he used it with his Mac Book. Aperantly when I clicked OK in disk management I converted the from HFS+ file system to something else. Is there any way to undo the disk convert? I immediately removed the drive, so there was no writing to it. Windows did not format the drive, it just converted it. Is the data still there? All the data recovery programs I have are for windows, can they read the Mac file system? I need to get the data back, what can I do?

• Super-Charge GIMP’s Image Editing Capabilities with G’MIC [Cross-Platform]

  - by Asian Angel

  Recently we showed you how to enhance GIMP’s image editing power and today we help you super-charge GIMP even more. G’MIC (GREYC’s Magic Image Converter) will add an impressive array of filters and effects to your GIMP installation for image editing goodness. Note: We applied the Contrast Swiss Mask filter to the image shown in the screenshot above to create a nice, warm sunset effect. To add the new PPA open the Ubuntu Software Center, go to the Edit Menu, and select Software Sources. Access the Other Software Tab in the Software Sources Window and add the first of the PPAs shown below (outlined in red). The second PPA will be automatically added to your system. Once you have the new PPAs set up, go back to the Ubuntu Software Center and do a search for “G’MIC”. You will find two listings available and can select either one to add G’MIC to your system (both work equally well). Click on More Info for the listing that you choose and scroll down to where Add-ons are listed. Make sure to select the Add-on listed, click Apply Changes when it appears, and then click Install. We have both shown here for your convenience… When you get ready to use G’MIC to enhance an image, go to the Filters Menu and select G’MIC. A new window will appear where you can select from an impressive array of filters available for your use. Have fun! Command Line Installation For those of you who prefer using the command line for installation use the following commands: sudo add-apt-repository ppa:ferramroberto/gimp sudo apt-get update sudo apt-get install gmic gimp-gmic Links Note: G’MIC is available for Linux, Windows, and Mac. G’MIC PPA at Launchpad [via Web Upd8] G’MIC Homepage at Sourceforge *Downloads for all three platforms available here.

• Getting started with object detection - Image segmentation algorithm

  - by Dev Kanchen

  Just getting started on a hobby object-detection project. My aim is to understand the underlying algorithms and to this end the overall accuracy of the results is (currently) more important than actual run-time. I'm starting with trying to find a good image segmentation algorithm that provide a good jump-off point for the object detection phase. The target images would be "real-world" scenes. I found two techniques which mirrored my thoughts on how to go about this: Graph-based Image Segmentation: http://www.cs.cornell.edu/~dph/papers/seg-ijcv.pdf Contour and Texture Analysis for Image Segmentation: http://www.eng.utah.edu/~bresee/compvision/files/MalikBLS.pdf The first one was really intuitive to understand and seems simple enough to implement, while the second was closer to my initial thoughts on how to go about this (combine color/intensity and texture information to find regions). But it's an order of magnitude more complex (at least for me). My question is - are there any other algorithms I should be looking at that provide the kind of results that these two, specific papers have arrived at. Are there updated versions of these techniques already floating around. Like I mentioned earlier, the goal is relative accuracy of image segmentation (with an eventual aim to achieve a degree of accuracy of object detection) over runtime, with the algorithm being able to segment an image into "naturally" or perceptually important components, as these two algorithms do (each to varying extents). Thanks! P.S.1: I found these two papers after a couple of days of refining my search terms and learning new ones relevant to the exact kind of techniques I was looking for. :) I have just about reached the end of my personal Google creativity, which is why I am finally here! Thanks for the help. P.S.2: I couldn't find good tags for this question. If some relevant ones exist, @mods please add them. P.S.3: I do not know if this is a better fit for cstheory.stackexchange (or even cs.stackexchange). I looked but cstheory seems more appropriate for intricate algorithmic discussions than a broad question like this. Also, I couldn't find any relevant tags there either! But please do move if appropriate.

• backup exec - backup to disk offline

  - by Adam

  Hi We are running backup exec 9.1 doing a backup to disk to portable hard disk drives. When we run the backup manually it works fine. But when the backup is setup to run in the evening on a schedule it does not run as the backup to disk folders goes offline and therefore has to be switched back on line. After we have done this the backup runs and completes fine. Any ideas? We have tried leaving the progam open and this makes no difference. Server is Windows 2003 SBS

I had trouble getting this, because / is being mounted read-only (?!), which prevents most applications from running. Also, it may not be related, but I have the following worrying messages in dmesg: [ 10.084596] k8temp 0000:00:18.3: Temperature readouts might be wrong - check erratum #141 [ 10.098477] i2c i2c-0: nForce2 SMBus adapter at 0x600 [ 10.098483] ACPI: resource nForce2_smbus [io 0x0700-0x073f] conflicts with ACPI region SM00 [??? 0x00000700-0x0000073f flags 0x30] [ 10.098486] ACPI: This conflict may cause random problems and system instability [ 10.098487] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver [ 10.098509] i2c i2c-1: nForce2 SMBus adapter at 0x700 [ 10.112570] Linux agpgart interface v0.103 [ 10.155329] atk: Resources not safely usable due to acpi_enforce_resources kernel parameter [ 10.161506] it87: Found IT8712F chip at 0x290, revision 8 [ 10.161517] it87: VID is disabled (pins used for GPIO) [ 10.161527] it87: in3 is VCC (+5V) [ 10.161528] it87: in7 is VCCH (+5V Stand-By) [ 10.161560] ACPI: resource it87 [io 0x0295-0x0296] conflicts with ACPI region ECRE [??? 0x00000290-0x000002af flags 0x45] [ 10.161562] ACPI: This conflict may cause random problems and system instability [ 10.161564] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver [UPDATE 2] I swapped in a new SATA cable, per Phil's suggestion.

• Virtual Disk Service Loader has stopped working

  - by Leigh Riffel

  We have several relatively recent (less than 1 week) installations of Windows Server 2008 R2 Enterprise that are getting this error whenever we open Disk Management. The application name is vdsldr.exe and the Problem Event Name is BEX64. The windows firewall was turned off and the service disabled. The Virtual Disk service was started (identical results when it is stopped). The computers are virtual machines running on VSphere, so that could be part of the problem. The strange thing is that Disk Manager worked fine when the VMs were first created.

• How to update the hard disk device drivers for a ghosted hard drive image so it can run on different hardware: Ultra ATA > SATA

  - by rism

  I've ghosted a Winxp machine from one laptop with Ultra ATA drive, and would like to set it up on another laptop as a multiboot option on another hard driver with a SATA drive. I can install the partition fine but if i make it active and try to boot it it blue screens. The blue screen is so fast i cant even read it, other than to make out it's saying "something", im picking probably hard drive as it goes through POST fine. So basically i would like to boot into my Win7 OS, and then somehow manipulate the XP partition to use updated drivers for the new hard drive/laptop so that i can then at least boot into the XP OS on the new machine and update all the other drivers in safe mode or whatever to get it to run. I assume someone is going to tell me to just do a fresh install, but that kinda defeats the purpose of ghosting at this point. There is a significant amount of personalisation, development setup on the XP machine that i would like to just transfer as is. As it stands ive invested minmal time in getting it to run, just a ghost and recovery and then a blue screen boot or two, so its still well worth it to me, time wise to try this way. Thanks.

• Beeping Hard Disk - Seagate 250GB Momentus 5400.6

  - by Pez Cuckow

  I have been trying to repair a laptop that simply beeps instead of booting. After taking it apart I have now realised that it is the hard disk beeping. I know that may sound strange but I guarantee that is what it is! (Currently powered on it's own with a Sata Mains lead). The beeping is slightly faster than one per second there is a link to this recording. This recording was made resting the mic on the hard disk while it was sat on a table on it's own, there are no speakers anywhere near, the sound is coming from the hard disk. Does anyone know what this beep means? Is the hard drive just dead, or is it fixable and the data recoverable? Many thanks,

• Add physical disk to KVM virtual machine

  - by evan

  I'm setting up a file server (nas4free) as a KVM virtual machine on a Ubuntu Server 12.04 system. How do I add physical hard drives directly to the VM so they can be used by the guest (nas4free), but not the host? Specifically the hard drive I'd like to mount is /dev/sda (which is not currently mounted on the server.) So far I've found two solutions but I haven't gotten either to work. The first is from Server Fault where it's suggested to use virt-manager. I haven't gotent this to work because when I try to select an existing drive nothing is being listed. My best guess as to why this is, is because I'm using virt-manager over ssh and not connecting as root, should that make a difference? The second solution I've found here is to just run the command (modified for my system) qm set nas4free -virtio /dev/sda but that seems to require proxmox which I don't have installed and doesn't seem to be in the default repositories? Finally, once the above is sorted out and I can mount the drive directly to the VM, does anyone have an experience with whether the drive should be mounted to the VM as scsi, ide, or virtio? (I know virtio was recommend in the linked ServerFault page, but I hadn't heard of it before now since I mainly use VMWare). Thanks for your help!!!

• Freeing disk space on Ubuntu to use in Windows

  - by Alex

  I have 250Gb drive on a laptop, which has Windows 7 on a 122Gb ntfs partition (which has a "boot" flag on it) and Ubuntu 12.04.1 on a 110Gb extended partition, of which the root ext4 partition is 108Gb and the swap is 1.74Gb. You can see everything in the screenshot below. My question is: I want to diminish the size of the linux root partition and then use that space to increase the windows partition. How do I do that? Also, is it possible to increase the size of the swap partition and not do any damage? If so, how? I'm using GParted, and i'd say i'm pretty confident with it. Screenshot of my partitions

• Monitoring Database disk space

  - by Michael Freidgeim

  An article Data files: To Autogrow Or Not To Autogrow? recommends NOT to rely on auto-grow, because it causing delays in unplanned times.We should mtonitor database files(both data and log), and if they close to max capacity, manually increase the size. However it doesn't give references, how to monitor the free space inside databases. I've tried to look how to do it. It can be done manually using   execute sp_spaceused for the database in question or  sp_SOS (can be downloaded from http://searchsqlserver.techtarget.com/tip/Find-size-of-SQL-Server-tables-and-other-objects-with-stored-procedure)Alternatively you can run SQL commands as suggested in Http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=82359 by Michael Valentine Jonesselect [FREE_SPACE_MB] = convert(decimal(12,2),round((a.size-fileproperty(a.name,'SpaceUsed'))/128.000,2)) from dbo.sysfiles aMore useful article Monitor database file sizes with SQL Server Jobs describes how to setup monitoring Finally I found the excellent articleManaging Database Data Usage With Custom Space Alerts, that can be followed even support personnel without much DBA experience.

• 1Tb disk formatted on Linux won't mount on windows nor mac

  - by Pedro MC

  I have an external HD (western digital) with 1Tb. I use Linux but I wanted to reserve a cross platform partition on the disk. I decided to create two partitions and used the "disks" application to do it. I created one partition with the LUKS (version 1) encryption and the other one, cross platform, in NTFS filesystem. Things work fine on my OS but when I try to use the disk (the cross platform partition) on both windows and mac the device is not recognized. What could it be? Next, output of "sfdisk -l /dev/sdb": Disk /dev/sdb: 121600 cylinders, 255 heads, 63 sectors/track Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/sdb1 0+ 36473- 36473- 292968750 83 Linux /dev/sdb2 36473+ 121600- 85128- 683789062+ 83 Linux /dev/sdb3 0 - 0 0 0 Empty /dev/sdb4 0 - 0 0 0 Empty

• Different block sizes for partition and underlying logical disk on HP Raid Controller (Linux)

  - by Wawrzek

  Following links collected in this thread I started to check blockdev and found the following output indicating different sizes for partition c0d9p1 and the underlying device (c0d9): [root@machine ~]# blockdev --report /dev/cciss/c0d9 RO RA SSZ BSZ StartSec Size Device rw 256 512 4096 0 3906963632 /dev/cciss/c0d9 [root@machine ~]# blockdev --report /dev/cciss/c0d9p1 RO RA SSZ BSZ StartSec Size Device rw 256 512 2048 1 3906959039 /dev/cciss/c0d9p1 We have a lot of small files, so yes the block size is smaller than normal. The device is a logical driver on an HP P410 raid controller, simple disk without any raid - RAID 0 on one disk to be precise. (Please note that above configuration is a feature not a bug). Therefore, I have the following questions. Can the above discrepancy in the block size affect disk performance? Can I control the block size using hpacucli?

• Can a virus corrupt a hard disk?

  - by sundar

  Shorter version: Hard disk corrupt, vendor claims warranty does not apply since it was "due to a virus" and "problems due to software are not covered under the warranty". Longer version: My Dell laptop recently refused to boot, and all attempts to 'repair' the Vista installation using the provided installation CD failed. I called up Dell support, and a representative took the laptop and after a day said the hard disk is corrupt. When I tried to ask for a replacement under the warranty, an official replied that the corruption was due to a virus, and "problems due to software are not covered under the warranty". Now, I get a doubt that he's trying to avoid having to provide it under the warranty. Is it possible for a hard disk to get corrupt due to a virus? If yes, is there any way we can detect it was due to a virus (as he claims to have detected)?

• Format an external hard disk

  - by Alex

  I am trying to format an external hard disk to FAT32 (I need it to work with some hardware that expects it to be in FAT32). When I am trying to format it via windows the only option I'm getting is to format it to NTFS. Another strange thing is that when I am trying to format one of my own partitions (on the hard disk that is running the OS) I can do it only in NTFS while another partition my OS can format in both NTFS and FAT32. What can cause such a behavior and how can I format the external hard disk to FAT32?

  So I've downloaded Gparted and Disks from the software center. According to software center, they've both installed successfully... but they're nowhere to be found. Even in my terminal: $ palimpsest palimpsest: command not found I've looked in usr/bin... no "palimpsest", no "gnome-disk-utility". In usr/share/gnome-disk-utility there's a bunch of .ui files. According to Software Center, both programs are now installed in my computer, but it seems I've no way to find them. I've tried re-installing and restarting. I'm on Xubuntu 32 bit.

• Inline Image in ASP.NET

  - by Ricardo Peres

  Inline images is a technique that, instead of referring to an external URL, includes all of the image’s content in the HTML itself, in the form of a Base64-encoded string. It avoids a second browser request, at the cost of making the HTML page slightly heavier and not using cache. Not all browsers support it, but current versions of IE, Firefox and Chrome do. In order to use inline images, you must write the img element’s src attribute like this: 1: <img src="data:image/gif;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub/ 2: /ge8WSLf/rhf/3kdbW1mxsbP//mf///yH5BAAAAAAALAAAAAAQAA4AAARe8L1Ekyky67QZ1hLnjM5UUde0ECwLJoExKcpp 3: V0aCcGCmTIHEIUEqjgaORCMxIC6e0CcguWw6aFjsVMkkIr7g77ZKPJjPZqIyd7sJAgVGoEGv2xsBxqNgYPj/gAwXEQA7" 4: width="16" height="14" alt="embedded folder icon"/> The syntax is: data:[<mediatype>][;base64],<data> I developed a simple control that allows you to use inline images in your ASP.NET pages. Here it is: 1: public class InnerImage: Image 2: { 3: protected override void OnInit(EventArgs e) 4: { 5: String imagePath = this.Context.Server.MapPath(this.ImageUrl); 6: String extension = Path.GetExtension(imagePath).Substring(1); 7: Byte[] imageData = File.ReadAllBytes(imagePath); 8:  9: this.ImageUrl = String.Format("data:image/{0};base64,{1}", extension, Convert.ToBase64String(imageData)); 10:  11: base.OnInit(e); 12: } 13: } Simple, don’t you think?
