Ubuntu :: How Can I Detect If Disk Is Formatted As Gpt Or Mbr

Apr 29, 2011

How can i detect if my disk is formatted as gpt or mbr?I suppose in principle this could be done by somehow reading a few bytes (no more than say 10K) from the beginning and possibly the end of the disk? But there surely is a program around that does exactly this, maybe some variation of or argument to fdisk or grub?

Hardware :: USB DISK Formatted Ext4 Not Working?

Feb 2, 2011

I formatted a 500GB with ext4 format, and placed in a usb box, it showed up, but could not write, copy past etc to it, the same disk was formatted in NTFS, and FAT32 showed up and could do all the above actions, given that ext4/ext4/ext2 are specifically made for Linux, then why on earth they don't get mounted automatically and work normally from usb box and ports?

Ubuntu :: Disk Formatted In Error - Boot Sector Repair

Nov 20, 2010

I was using the disk utility on Ubuntu 10.04 and wanted to make by 500GB external NTFS formatted USB drive into 1 x 50GB FAT32 and 1 x 450GB NTFS. I clicked the option that said format or create a partition and it basically wiped the whole thing in a split second leaving me with 500GB of seemingly empty space. Obviously the files are still there but I cannot boot the drive to view anything. I have downloaded testdisk, but don't know how to use it, but I am sure there is a relatively simple solution here. I am currently repairing the boot sector of the drive as Test Disk showed the drive as "no type" i.e. not FAT/NTFS/ext4 etc., but shows the correct amount of used space though, but I cannot view anything err go, I cannot use the undelete command as yet.

Fedora :: Accessing Newly Formatted Disk (JFS Filesystem)

May 9, 2010

I have just formatted an external USB disk with a JFS filesystem. The partition shows up in 'Computer', and it mounts, but if I try and copy and files onto it, it will not do it. Clearly, Nautilus is mounting it read-only. How do I get this to behave like my USB Flash drive, where I plug it in, and its automatically mounted read/write?

Ubuntu :: Find Out Which Was The Original Installation Version That First Installed After Formatted The Disk

Sep 12, 2010

I have been upgrading Ubuntu as its new distributions are released every six months regularly since quite some time now. Is there a way I can find out which was the original installation version that I first installed after I formatted my disk. I mean as far as I remember I have been using this state of my Ubuntu since 8.04 and have been upgrading since then, but I am not sure.

Ubuntu :: Drive Formatted - Mount Partition For Disk Data Recovery

Nov 1, 2010

I accidentally formatted a 2TB drive of mine (big oops), but have recovered 2 of the 3 partitions using testdisk. My third partition is a LUKS encrypted partition. Testdisk managed to recover a piece of it, but it won't mount as most of it is unallocated. The partition originally occupied all space from sector 2,930,272,065 to the end of the disk -- sector 3,907,024,064. That is about 473 GBs. Currently, the partition only uses space from sector 2,930,272,065 to 2,930,288,129, about 7.84 MB.

The rest of the space is unallocated. Now what I need to do, is to expand the partition so that it occupies all the space that it used to. How would I do this? I cannot resize the partition, cause it would try to recreate the filesystem AFAIK and I don't want that, as it will fry my data. My data is not terribly important, but I would rather have it then not. I attached a screenie of kpartitionmanager. The partition in question is /dev/sdb2.

Ubuntu Installation :: 10.04 Server - 64 Bit - Installer Won't Detect Disk

Oct 5, 2010

I have a Dell Poweredge 2970 2x3.0 GHz AMD 64bit dual core, Perc 5/i controller, and 2 brand new Fujitso SAS 15K 146GB drives.

Trying to install Ubuntu 10.04 Server 64 bit from USB. At the point of detecting disks, the installer only recognizes the USB. The installation was created using Pendriveinstaller ver1.8.0.1 per Ubuntu Server web site instructions. I have the drives configured as 2 separate raid 0 arrays using the bios raid configurator. The drives have been initialized. (Tried before with a single Raid 1 array, but had same issue and since have read Ubuntu support for hardware raid is not great, so was going to bypass hardware raid for now).

I've seen some chatter on here about opening a terminal at this point and removing dmraid but don't see an option for terminal only shell.

Fedora Installation :: Installer Cannot Detect My Target Disk ?

Jul 12, 2010

I have a dual CPU Xeon machine that I have been using various versions of fedora on for years.

The machine has the following disk layout:

I currently have Fedora 10 and grub installed on hda and I had to jump through hoops to install such as disabling the promise controller and reassigning drives because that blasted /dev/mapper kept grabbing the Maxtor ATA drives although I didn't want it to.

Anyway, in the BIOS I can boot from the secondary IDE controller so I want to install Fedora 13 on hdb. Problem is, the Fedora installer won't detect the drive.

Its partition table is as follows:

There is approximately 69GB of free space on this disk but the blasted python based installer wont show the disk as a possible installation location. If I exit to a bash shell I see that the device nodes do exist and I can manually mount and manipulate the disk but the installer is brain dead where the disk is concerned.

I will mention that sdc, sdi, and sdj are used with mdadm to create high performance striped volumes. Also, sdc shows up under /dev/mapper and I don't want to use /dev/mapper at all. I want simple /dev/sd? mount points...no stinking /dev/mapper, and no stinkin volume manager wrappers...

Why I cannot get the installer to use /dev/sdb?

Is there a disk signature on /dev/hd[bc] that is causing them to be grabbed by /dev/mapper, and if so, how would I remove that signature from the drive? /dev/mapper is vacant under Fedora 10.

Fedora Installation :: 13 Installer Don't Detect Usb Hard Disk

Oct 12, 2010

I have a ssd cosair harddisk with both usb and sata connecters. If I connect it with sata anything is working fine, and I managed to install Fedora core 13.

But I also want to be able to use the harddisk when it is connected with usb and that causes problems.

When I boot the Fedora Core 13 dvd It can't detect my usb harddisk.

When booting in install mode it just don't detect the harddisk.

When booting the dvd in rescue mode it don't detect the harddisk, and it don't create any entries in /dev/ for the harddisk. It is like there is no disk at all.

I have tested this on 3 different computers, so it is not a problem with my specific motherboard. So either it is a problem between my harddisk and Fedora Core 13, or there is some problems with the usb drivers in the boot image used by the Fedora core 13 dvd.

The disk is working fine if I connect it via usb to an existing Windows install, so the usb connection is working.

I installed Fedora core 13 with the harddisk connected to sata and then re-connected the harddisk to usb. It then boot up, but complain about missing root filesystem. Most likely caused by missing usb driver in my kernel.

But anyway, what I really want is the ability to boot from both sata and usb, so I can take the harddisk with me and boot it on other computers with usb.

So is there a command which allows me to build an kernel image which can boot from usb or am I trying to do something which is not really supported?

I did update my fstab to use LABEL=myroot

There is 1 Windows partition(NTFS) and 1 linux partition on the disk. (No seperate /boot partition and no swap)

General :: Installation Detect Disk Freeze / Hang - Resolve It?

Apr 26, 2011

I have a problem with getting my Linux distribution (Debian amd64-bit) to install. Everything works the way it should - from booting a live CD/DVD (any distro) to running the text-based or gui installation right after bootup. Up until the Linux installation gets to the step for detecting my SATA hard disk drive(s), but before (or at the same time as) initiating the partitioning step, it'll freeze/hang my screen and my CD/DVD drives instantaneously - and the only fix is a forced shutdown and/or hard reboot.

I don't know what causes this, but I tried googling online and all that I really found out was that it might be an issue with running 32-bit vs 64-bit installations - but this is not the case; from running Gparted on Knoppix 32-bit or the partitioning step during a Debian 64-bit installation. Also, I read a random post online related to running kernel commands / parameters alongside the installation (e.g. acpi=off or something similar) stating that it might help?

Anyone got any ideas or solutions? I'm a real newbie when it comes to Linux (though, I'm quite knowledgeable when it comes to computers and technology, and Windows) - else I wouldn't be posting in this forum sub-section, hehe. I can't quite get my head around this one - despite trying my best to find a solution online beforehand.

Fedora Installation :: 11 Installer Doesn't Detect Seagate Sata Disk

Jul 8, 2009

I have an Asus P5K motherboard with an Intel Core 2 Duo 8400. It has 2 SATA hard disks, a 250 GB Seagate and a 500GB Hitachi.

I've been running Fedora 10 x86_64 for 6 months on this computer without problems.

I'm trying to do a new Fedora 11 install on this computer but the installer (Anaconda?) only detects the Hitachi disk.

I've tried to make a new Fedora 10 install to check if it was a media or disk problem and it detects the two hard disks.

I've tried to install it via a Live CD, and the installer only detects the Hitachi disk. The LiveCD detects the two hard disks, I can access it, partition, format, write, but the installer only detects the Hitachi.

I've tried to change from Enhanced SATA (AHCI) to Compatible in BIOS without success and I've changed SATA cables from one disk to the other, changed the disk order and nothing.

Must I enter some boot parameters for Fedora 11? Has the LiveCD installer some options?

Debian Installation :: 'Squeeze' AMD64 Installer Fails To Detect Hard Disk

Apr 20, 2011

Having trouble installing 'Squeeze' 6.0.1a-amd64-netinst on a new AMD64 system.The installer boots and runs fine until it gets to hard disk detection. Then it hangs for about 20 minutes showing a blue screen, during which time the HDD-activity light flickers every 5 seconds. Eventually it says it can't detect a hard disk, and displays a (longish) list of possible drivers; no idea which, if any, would suit.Anyone else installed (successfully or otherwise) on this combo?

Security :: Detect Viruses Inside The .vmdk - VMware - Virtual MAchine Disk Format - Image?

Feb 6, 2011

I have set up a virtual machine under VMware Player 3.1.2 in Debian. Operating system of this virtual machine is a Windows Server 2003. I would like to periodically test this Windows Server 2003 installation for viruses. Obvious solution would be to install an AV software under this Windows Server 2003 installation. However, I was wondering, is this possible to use NOD32 for Linux or clamav in order to test this Windows Server 2003 installation for viruses? Is NOD32 for Linux able to detect viruses inside the .vmdk file?

Debian Multimedia :: XOrg Auto-detect Failing To Detect Max Screen Resolution

May 29, 2011

I've installed Squeeze 2.6.32-5-amd64 on my laptop (Alienware M17X R3, Intel i7 Sandybridge, ATI Technologies Inc Broadway [ATI Mobility Radeon HD 6800 Series])The screen is 17", with maximum resolution of 1920 x 1080. After a default install of the operating system, the maximum resolution I can select is 1280 x 1024.My research so far has suggested that I need to edit the /etc/X11/xorg.conf file and provide xorg with the necessary resolution.

Again, by default, the xorg.conf file is not created. This leads me to believe that xorg is scanning my hardware at startup and providing me with whatever it thinks is appropriate. I tried following these instructions to generate an xorg.conf file. This process created an xorg.conf file under /root/.

When I copy this xorg.conf file to /etc/X11, I get a blank (i.e. black) screen. Deleting this file restores the default resolution 1280 x 1024.This system is dual booting with Windows 7. Under windows I am able to get a 1920 x 1080 resolution, so I know my hardware is up to it.At this stage I have yet to install the drivers for the Radeon graphics card.What are my options regarding configuring xorg to give me a higher screen resolution?

Debian :: Where To Find The Fw-detect Command ? (for Firmware / Wireless Detect)

Jan 12, 2010

Code...
To find the appropriate firmware without knowing the make or brand of your wireless chip, you can use the command:

#fw-detect

But apparently debian package do not offer this useful tool, well, certainly for sidux exclusively.

Is there a package of fw-detect eventually?

Ubuntu :: Recovering Files From Formatted HDD

Jan 24, 2010

While trying to create a bootable SD to install Ubuntu on a netbook, I accidentally formatted a part of a removable HDD that was connected to my computer. If I remember correctly, the partition I formatted wasn't the main partition of the HDD. In that case, does it make sense that the whole disk was wiped out? On that HDD there's a year worth of work, I really need that back.

I was using PhotoRec with some luck: it started to recover files, but with no names, which is almost useless, considering a lot of it are recordings - useless without their names. Is there any good recovery program that will recover all my files incl. names? Is there a easier oprtion, considering that I think I didn't really format the big partition of the HDD? What may it have been, the small partition?

Ubuntu :: Formatted HD While Installing - Restore?

Oct 29, 2010

I have just installed my first Ubuntu. While installing it, I have checked the box "Install with other OS". The next step was to choose partition where to install Ubuntu. There I checked "whole partition", because I wanted Ubuntu on the same partition where my Win7 was, and I thought that it will save all the data because in previous step I checked that box. However, it didn't saved anything. My hard disk is formatted and I didn't saved any data Is there any way that I can restore my system to previous state, or at least to retrieve some data?

Ubuntu :: Unable To Create Formatted Partitions

Mar 13, 2010

I can't create any formatted partitions in my hdd (/dev/sda) with Gparted or KDE Partition Manager.

With either I can only create an unformatted partition. When trying to reformat it, I get this: [URL]

Quote:

WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy). As a result, it may not reflect all of your changes until after reboot.

So the problem is apprarently at kernel level. After that the partition will of course just be shown as "Unknown" - even after a reboot. What kinda app could possibly reserve my partition table?
