Fedora :: Sfdisk Refuses To Work - Says Sda Is Busy ?
Feb 26, 2010I have 2 HDs, an old one with LVM (sda) with two partitions, sda1 and sda2, and the new one without LVM (sdb). I want to format the old sda device. I tried with sfdisk, but it says that the sda is busy:
But there is no call in /etc/fstab to sda, I did a /sbin/swapoff -a, and this is the output of df:
lsof tells me no one is using sda, sda1 or sda2.
So, why does sfdisk refuse to work?
Software :: Sfdisk Starts Partition From Sector 1 Instead Of 63?
May 1, 2011Slackware 13.1,using "sfdisk".I need to use this one as it can be used in a non-interactive mode,"parted"is not a solution for me.Inside my own script I make the partition like this:
Code:
# MAKING PATITION:
set `losetup -f`; dev=$1
`losetup $dev $out`
sfdisk $dev << EOF
,,$fsys
EOF
However after formatting this single partition in FAT16 I can see the drive in my emulated Windows311, but not use it. It says that the drive cannot be accessed. When I do the same thing interactively with fdisk it all works. When inspecting the partitions in both cases via "fdisk -ul" I see that whenever sfdisk is used to create the partition it is created starting from the 1 sector. Whenever fdisk is used it is created from 63 sector (which is correct of course). How can I make my sfdisk start the partition not from the 1st sector, but also from the 63 so that OS wouldn't have problem with that?
I tried like this:
Code:
sfdisk -uS $dev << EOF
63,,$fsys
EOF
But it then just says that the partition does not end on the boundary. Trying to see the content with fdisk -ul says that partition table is incorrect. So doing it this way doesn't work.
Hardware :: Recovering Partition Table Using TestDisk And Sfdisk?
Jul 16, 2010Something bad happened to my partition table,so right now I'm working from a Live CD. My partition table is completely screwed, although the data on the lost partitions hasn't been overwritten. I've been messing around with TestDisk for about an hour, but I still didn't figure out how to fix my problem. Before the crash, I had 5 partitions:
NTFS - 30GB
NTFS - 8GB
ext4 - 20GB
and here comes the extended partition:
linux swap - 8 GB
NTFS - 400GB
TestDisk can see all those five partitions. I can mark swap as Logical, but I can't do so with the 400GB NTFS partition - there is just no selection. Turning on "expert mode" didn't help. I have read about using sfdisk to fix partition table, but I don't think I'm able to do it by myself.
Here's how it looks in TestDisk:
Code:
Disk /dev/sda - 500 GB / 465 GiB - CHS 60802 255 63
Partition Start End Size in sectors
D HPFS - NTFS 0 1 1 3915 254 63 62910477
D HPFS - NTFS 3916 0 1 4959 254 63 16771860 [Windows XP]
[code]....
I've filled sizes according to TestDisk's findings. First 3 partitions were OK, the problem lies in the extended partition holding 2 logical ones. By the way, TestDisk is able to enter the 400gb partition and see the files.

Jun 24, 2011I have a proprietary device - something like an iPad screen - which has a front panel display with touchscreen buttons that work internally as a USB keyboard. During testing/debugging I want to connect it to another keyboard via the external USB port.Any application which I open on the device by pressing some characters on the touchscreen accepts input codes from either USB keyboard. I want to limit the touchscreen USB keyboard input only to a specific set of apps.Is there a program which can help me detect which USB port or device the code is coming from? Or someway I can map one keyboard to send a different set of codes? The device is using Linux.

Oct 7, 2009My old Intrepid box got old and senile in the hardware, so I had to take it back round the shed and put her down.I buried her next to her favorite tree in the backyard. So yes, I got this new Mini ITX setup with a dual core Atom processor and 4 gigs of ram for my new computer. I'm going to use it as a media center in my living room. However Atom 1.6 ghz is no screamer so I'd like to build a system using a light weight operating environment to leave more power for running programs and playing my media.
I could install the latest version of Kubuntu again but I thought this time I'd try to get a bit deeper into Linux and educate myself. Could someone clarify the differences between XFree86, Window Manager, and a Desktop Environment (KDE/GNOME/etc)? I know it goes like Hardware -> XServer -> XFree86 -> Window Manager (I read the tutorial on linux.org). But where does KDE or a "Desktop Environment" come in? Is KDE a decked out window manager with its own programs that runs on top of XFree86 or what? Or does it totally replace XFree86?
General :: What Are Basic Differences Between Desktops?
Jun 4, 2010I took the simple approach and installed the gnome desktop, but I have read about KDE and Xfce and am curious. There may be a lot more that I just haven't heard about yet too.

Also, what are the basic differences between the desktops?

This probably sounds like a stupid question but I'm having a lot of trouble clearly differentiating between a shell (such as Bourne or bash) and the Terminal application in GNOME. I realise that both are completely different but I can't seem to find a clear answer written in text. Could anyone clearly distinguish between both?

General :: What Are The Differences Between Shell , Console & Terminal
Jul 23, 2011I have come across the use of the term terminal, virtual terminals/consoles, real-text terminals but do not understand what terminal refers to. Does it refer to the screen that is in-front of me whilst I post this question or does it refer to something specific?EDITI came across a similar post at What are the differences between shell , console & terminal? and it seems to be similar to the one I posted although am still confused about the use of the sentence Decades ago, this was a physical device consisting of little more than a monitor and keyboard. What does this device look like and how is different to a monitor?

General :: Copying And Moving Operations And Their Performance Differences?
Oct 13, 2010[code]...
Well, let's suppose the file is very large, say 10 GB of disk space it is consuming. We perform the above steps. Which operations: cp (copying) or mv (moving) will be more efficient and less time consuming? The inode number 1566966 which was pointing to the file in my home directory is now pointing to the same file which is in some other directry, i.e. /tmp/. Isn't the inode value getting modified in some ways to point to the correct location / beginning of the data block on the hard disk? If the the physical location of the data would not change then we would not be able to free up space in our home directory. That means the mv operation is copying the file into some other location. In other words, it is also performing the cp operation first and then deleting the file from its original location, my home directory in the case above. However, when a file is copied it's inode value changes. But the mv operation is retaining the same indoe value. So, how to determine which operation - mv or cp - is more CPU-friendly or more efficient in terms of performance and time taken to perform the action?
