• unable to format external drive to HFS+ for Mac

  - by dtlussier

  I have an external hard drive (1 TB Western Digital) that is currently formatted as FAT32 and I want to reformat it to a single partition of HFS+ for my Mac. I realize that I can read FAT32 from my Mac but want HFS as it has other feathers like permissions that I'd like to have. I have tried using Disk Utility to format the drive as I have done in the past, but when I go through the process it fails and throws out an error stating that it is unable to reformat the drive to HFS. What might be the reasons that this could happen? Are there any diagnostics I could run on the physical disk to check if it is running well?

• What would cause a single working website to not work on 1 out of 5 devices on a network?

  - by th3dude

  There is a specific website that loads up without problem on all machines on my network (both wired and wireless) except one laptop. This laptop is a Windows 7 machine that was just recovered using the recovery partition, so it is fresh. The site will not load in Firefox 3.6 or IE 8. The website is http://www.weightwacthers.com The site loads fine on my desktop, iPhone, and Droid, but not the laptop. In all my years in this business I've honestly never seen this happen. Also, 'Is it down for me or everyone' reports that it is indeed only me. What would cause this to happen?

• Booting a native Windows install in Virtualbox: is it possible?

  - by Aron Rotteveel

  I am looking for something similiar to Bootcamp. Currently, I run Ubuntu Maveric as my primary operating system and run Windows 7 in Virtualbox. For some tasks, however, running Windows virtualized just seems to result in too much overhead and speed loss, and I'd like to be able to boot natively. The ideal situation would be to setup Windows and Ubuntu in dual boot on seperate partitions, with the ability to boot the Windows partition in Virtualbox on Ubuntu as well. Is this possible? Also, how it is that Bootcamp seems to be the only system capable of this?

• Best alternatives to recover lost directories in FAT32 external hard drive?

  - by Sergio

  I have an 320 GB ADATA CH91 external hard drive. I guess it has some problems with the connector of the USB jack. The point is that in certain occasions it fails in write operations generating data losses. Right now I lost a directory with several GB's of very useful information. Since then I have not attempted to write to the disk any more. What tool would you recommend to recover the lost data? The disk is FAT32 formatted (only one partition) and I use both Linux and Windows. What filesystem format would you recommend to avoid future data losses? I currently only use this external hard drive in Linux so there are several available choices (FAT, NTFS, ext3, ext4, reiser, etc.).

• Bootcamp: setup of Windows 7 (64 bit) hanging at "disk.sys"

  - by Skade

  I am having trouble getting Windows 7 Professional (64bit) to install on a Macbook Pro (late 2010 model). The installer hangs when loading the setup from disk. When restarting, I get an option to boot Windows from disk. The installer then starts loading files from disk and suddenly hangs. Using "Safe Mode" (from the advanced menu), it tells me that the installer hangs when loading "disk.sys". The installation is made on a fresh Bootcamp partition, the disk uses GPT. Has anyone seen this before and maybe found a solution?

• Only show changed files while syncing from ext4 to NTFS

  - by qox

  I would like rsync to print modified and deleted files. The verbose option (-v) does print modified files but also the list of subdirectories, maybe because touched directories are considered modified. Since I sync a lot of files from a lot of subdirectories, it's impossible to see the actual changes. So, is there a way to not print directories using rsync ? Im not looking for grep -v "*/$" kind of answers since it would also exclude new directories. Command I am using: rsync -avh --delete /media/data/src /media/data/bkp And everytime it prints the list of all directories: src/dir1/ src/dir1/sdir1/ src/dir1/sdir2/ src/dir2/ ..... Thanks for your help. EDIT: Ok, after some intensive tests .. It doesn't print all directories when syncing from an ext4 partition to an ext4 and from NTFS to NTFS. It only does when syncing from ext4 to NTFS .. And options '-c' or '--omit-dir-times' don't change that.

• Ways to improve completeness of files for data recovery and scanning?

  - by SteveO

  I am using R-studio for data recovery on one of my ntfs partition. There is a pdf file about 16MB, but the software can only recover 15MB of it. So I am thinking about what ways can be used to improve the quality of scanning and recovery by the software? I am looking around its preferences. I am not quite sure whether there are some adjustable parameters for scanning and recovery which can be fine-tuned to improve the quality? R-studio has a free demo version, for which scanning is free,but recovery isn't. It is downloadable from http://www.data-recovery-software.net/Data_Recovery_Download.shtml Its manual is here http://www.r-tt.com/downloads/Recovery_Manual.pdf. I have tried my best to search for answers in the manual, but failed to find one. Their technical support is not as good as their software, and helpless usually in my opinion. Thanks!

• How to fix a folder content glitch in a FAT32 filesystem?

  - by kagali-san

  at my 450gb fat32 partition, a directory has a wrong content after improper usb drive disconnect; was: /files (total 250gb) /files/folder/ /files/folder2/ /files/somethn.gs Now: /files/weir?d?name, 5 mb Windows and Linux are saying that most (400 of 450gb) disk space is occupied, but sum of all files/dirs is about 130gb, so it seems that files are still there?. No write attempts since discovery; Rejected tools/methods: chkdsk(Windows7): checking completed, but no changes. fsck.vfat: attempted to ruin drive even more (there is a lot of LFN and unicode names). EasyRecovery. Didn't see the target folder (maybe wrong scan options? tried best match, but not raw scan - it would take days since the drive is usb 5200 rpm..).

• merging two partitions on ubuntu

  - by gthm geeky

  This is how my partitions look like in Ubuntu. I would like to merge two partitions /dev/sda8 and /dev/sda/7 because I am unable to use both of them. /dev/sda8 111G 2.7G 103G 3% / udev 1.9G 12K 1.9G 1% /dev tmpfs 763M 864K 762M 1% /run none 5.0M 0 5.0M 0% /run/lock none 1.9G 252K 1.9G 1% /run/shm none 100M 72K 100M 1% /run/user /dev/sda7 117G 52M 111G 1% /home Please let me know if there is any way to do it.

• VMware snapshost issue

  - by Calcgod

  I am using VMware Fusion 2.0 on a Macbook Pro. I have allocated 20GB to a windows partition within VMware, and now wish to expand that. When I go to the settings for the hard drive it tells me: "These settings cannot be changed while the virtual machine has a snapshot. To make changes, first delete all snapshots." When I go to the snapshots settings nothing appears there besides the current state thumbnail. Is there a way to remove these "invicible" snapshots??

• Turning a running Linux system into a KVM instance on another machine

  - by Charles

  I have two physical machines that I wish to virtualize. I can not (physically) plug the hard drives from either machine into the new machine that will act as their VM host, so I think that copying the entire structure of the system over using dd is out of the question. How can I best go about migrating these machines from their hardware to the KVM environment? I've set up empty, unformatted LVM logical volumes to host their filesystems, with the understanding that giving the VMs a real partition to work with achieves higher performance than sticking an image on the filesystem. Would I be better off creating new OS installs and rsyncing the differences over? FWIW, the two machines to be VM'd are running CentOS 5, and the host machine is running Ubuntu Server 10.04 for no particularly important reason. I doubt this matters too much, as it's still going to be KVM and libvert that matter.

• PCI IDE Controller

  - by mercutio

  I have a suspicion that the onboard IDE controllers may not be working. Every disk I use to setup this machine reports as damaged (using a win xp installation to test, since it gets to partition setup fastest) So, I popped an IDE PCI Controller card in, to test with, but no drives are showing up in the bios now. I went into setup and changed the BIOS settings to disable onboard IDE1 and 2 to test, but still didn't detect the drives. How do I get that working? It's a standard PC with a 160GB disk and DVD Drive on master and slave channels on a single cable, if that helps. Let me know what else I need to state.

• recovering vm data from crashed XenServer install

  - by user58983

  We're using xenserver 5.6 from citrix to run our virtual machines. The box is old and creaky, and the hard drive went. (We had a super limited budget of $0 at the time). Turns out the only machine on there we actually needed, was the only one not backed up... anyway, we've replace the hard drive, and reinstalled xensever. however while trying to find our old vm disk images, i have no idea where they sit, and i'm beginning to think they're on a lvm partition? is there anyway to access the disk images from the old vm's on this hard disk, which is attached to the xenserver machine via a usb-sata converter?

• Do I have to reinstall Mac OS in case something goes wrong during a Windows Boot Camp install?

  - by Rich Jennings

  I have a Macbook laptop running Snow Leopard, there's absolutely no information on the laptop, just a few unimportant files on it, I wanted to use Boot Camp Assistant (version 3) to create a partition and install Windows on it to run Windows alongside Mac OS. My CD/DVD drive doesn't work at all so I'm gonna have to mount Windows on a USB stick and install it from there. My question is, when I start Boot Camp it asks me to back up my files but I have nothing to back up, I was just wondering, in case I go through with the Windows install and something goes wrong do I have to reinstall Snow Leopard? My Snow Leopard install DVD can't be read by the laptop that's why I ask, I wouldn't know what to do if I had to reinstall it.

• Deleting Windows 8 install

  - by Yann4

  I have a windows 7 pc, and I had installed windows 8 on an SSD, so it was the only partition on that SSD. I've now realised that I never use it, so I went to uninstall it and followed these steps. The PC now boots into 7, as expected, however I can't delete or format the drive that has windows 8 on it. The format dropdown selection is greyed out, and I tried to just simply delete all of the files and use the disk as is, but as windows 8 isn't there, I no longer have rights to delete all of the files, apparently. The drive in question has 3 partitions, one that I made for the win8 system, and 2 smaller system-created partitions (one 300MB recovery and 1 100MB EFI) How do I go about formatting the drive?

• Why does moving large folders take a lot of time?

  - by acidzombie24

  What can i do to fix this? Drop permission properties? I have a large folder with 100k files. I moved it into my archive folder and its taking forever to move. Why is that? I know on XP it takes <1sec but not on windows 7. I am sure its a permission thing, is there a way i can disable it and make it faster? -edit- I am moving the folder into another in the same drive/partition. In XP. AFAIK it just moves the folder file from one place to another. In windows 7, it seems like its touching something in every file when i move it.

• how to reduce size (disk space) of windows 8?

  - by humanityANDpeace

  This questions is about what things I can do to reduce the size that Windows 8 uses. Background For example: At present and with only one programm installed (MS Access 2007) I have a about 15GB of my harddisk space used. I have little space (its a 17 GB partition on a SSD disk). I would like solutions that are like: Remove files not really needed (drivers not actually needed in the system) Help files not really needed (documentation) pagefile.sys (assuming I would have 4GB ram and no real need for swaping) hiberfil.sys (used for hibernate and sleep... I need that. though I would regain about 4GB space) At best I would like to delete mostly files that I would most likely not need. Though I have no good idea where to start there. Since my setup (hardware will not change) I would be willing to delete all the drivers that windows 8 has for hardware I do not have.... The question is about ways to reduce the space that Windows 8 uses.

• What is the easiest way to make a backup of an entire hard disk

  - by Solignis

  Hi there, I got myself a dell laptop from the local computer store. Its a used machine with Windows Vista Home Basic on it. I want to load Ubuntu Desktop 10.10 though so I can do perl development. BUT I want to keep a copy of the entire harddrive with the dell utility partition and Windows Vista in case I want to go back. I was thinking I could image the drive but I not sure what to use, I don't have Ghost or anything, Someone had told me about Clonezilla. Would that work for me? Is it hard to use? Also I want to burn the data to a DVD or something more storable than a harddisk.
