I have used fdisk command in windows environment.Just insert a bootable cd having fdisk into cdroom and start hard disk partitioning. I have been working in red hat/fedora Linux since many months.I always use gui interface to do my hard disk partition. Well i am eager to learn Fdisk under Linux. How can I use it ,Its method to create a a fdisk cd or it is in the 1st cd of the operating system ?

I've just installed Debian 6 on an old pc so i can use it as a file server.As far as i know installation went fine but it didn't detect my Edimax wireless network card.The problem I'm having is using FDISK. I tried to explore my CD drive and i got an error message "Unable to mount location". I wanted to see if there was an installer to install my network card becuase the manufacturer says it's supported by Linux. When i use the su - command and try using fdisk -l it just displays the command prompt and no hdd info. I tried it the other day becuase I want to mount all the physical drives and one logical volume. This is only the first step for me configuring this computer as a server and i'm suck already and ready to give up and try Windows server (whcih i don't really want to do).Has anyone got any ideas how i can mount my cdrom and why FDISK isn't working?

View 3 Replies View RelatedI have used fdisk to create two new partition.
Before this partition, I had 6 partition of which /dev/sda6 was the boot partition. I deleted /dev/sda5 partition and hence the earleir /dev/sda6 became /dev/sda5. Now I created two new partitions /dev/sda6 and /dev/sda7.
Due to this change in device label of /dev/sda6 I am not able to boot my computer.
Is there any method to change the disk label of /dev/sda5 to /dev/sda6 ?????
I would like to remove/create partitions on a harddrive without going into the menu of fdisk.
can one pass options to fdisk to create and delete without going into the menu? So that I can write a script to do that automatically.
Or if fdisk isn't capable, what other alternatives do I have?
The output of my fdisk command is as follows :-zodiac@gml-admin:~$ sudo fdisk -l[sudo] password for zodiac: Disk /dev/sda: 160.0 GB, 160041885696 bytes255 heads, 63sectors/track, 19457 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytes

I've a new external usb drive that was shipped formatted fat32. I wanted to convert this to ext3; so I performed a mkfs.ext3. I then noticed that fdisk was still reporting the usb drive as fat32 (even after reboot), but mount was reporting ext3: so I fdisk'ed the drive and change the partition's system id to 83 (Linux)
View 1 Replies View RelatedI have 3 Ubuntu installations & a PCLINUXOS, plus Windows XP installed on one hard disk. I still can boot to each one of them and can mount each one using Ubuntu.
The problem "may" have occurred when I reduced the size of some linux partitions using gparted. I still have plenty of space in each of those partitions.
When I started gparted all of the HD was unallocated. I did that from each ubuntu installation and the PCLINUX installation, plus LIVECDs. All indicated the space was unallocated.
When I did an fdisk -l from a Puppy Linux LiveCD I got a normal start and ends of each partition.
When I tried it from Ubuntu installation or live cd, I received the following types of responses:
Code:
ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda5
Disk /dev/sda5: 28.5 GB, 28566397440 bytes
255 heads, 63 sectors/track, 3473 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
ubuntu@ubuntu:~$ sudo fdisk -u /dev/sda5
The number of cylinders for this disk is set to 3473.There is nothing wrong with that, but this is larger than 1024,and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Plus the Windows partition seems to go over its limits.
Since all of my OS installations are still working, I don't know how critical this is. From reading another post, I understand this might be able to be fixed by making some changes in fstab.
I wonder whether to place swap partition on LVM or on standard fdisk partition which will not be in LVM.What is better and more often used on production ?
View 4 Replies View RelatedI fired up fdisk and got this warning:
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
I didn't even know that my previous Linux installs where DOS-compatible in any way!
Below is a print out of my partition Table from Fdisk, in Cylinder mode, Sector mode, and then in expert mode?
Why in expert mode does it look like Partitions 2 and 3 share the same sector / hd / Cylinders? Is this OK?

Is there any way to use 'fdisk -l' as a normal user? I see in F12, /sbin has been added to PATH by default for a normal user, but when trying to use it, nothing shows up.
See below for demonstration purposes:

Since installing 10.4 I've been having startup problems: I get a message requiring me to press S to mount various disks. Something which I've never really understood is: what is the relation between fdisk and fstab?At present fdisk gives sda1 and sda2 as my Linux partitions, sdb1 and sdb2 as my Windows partitions. fstab has:
/dev/sda1 /media/winboot ntfs
/dev/sda2 /media/windata ntfs
/dev/sdb1 /media/sdb1 ext3
/dev/sdb2 /media/sdb2 ntfs
/dev/sdb5 /media/sdb5 swap
which looks a bit sus to me. Am I supposed to make my fstab match fdisk, or does fstab modify the result of fdisk when it boots, or what?
I actually wanted to create partitions on my usbstick, but instead I fdisked new partitions onto my boot + datadrive. It is still running. Is there a chance I can recover that?

I know there are entries in FAQ and sticky topics about USB-drives, but I can't really make a use of any of them... I bought a new 1.5TB internal HDD and put it into an external HDD box connected to my PC via USB. The Problem is:

i have one harddisk /dev/sda it is partitioned as below:
/dev/sda1: /
/dev/sda2: swap
after the centos is installed, i want to create another partition /dev/sda3 to use all remaining disk space. i used fdisk. after fdisk, it requires reboot. The partition table has been altered! Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: Device or resource busy.The kernel still uses the old table. The new table will be used at the next reboot. Syncing disks.is reboot really necessary? is there any other tools which do not need to reboot?
Does anyone know if fdisk is currently blind to SATA drives? If so, is there an alternative command one can use to list ALL partitions, mounted and unmounted, that are available to the system?
View 12 Replies View RelatedI recently expanded the RAID on an iSCSI device which is shared out to a linux server. Fdisk correctly sees the new size but it won't let me add a third partition. It complains about overlapping partitions whenever I try to add it.If I 'remove' the partition, the overlapping error goes away. The interesting thing here is that when attempting to use the default sizes to setup the partition the printed screen shows completely different results (which I can understand is why its complaining about overlapping)
I'm not sure why its not accepting the cylinder sizes I want. Anyone have any ideas as to what's wrong here?
I have a Windows Vista machine on which I selected "utilize free space on selected drives" to install Fedora 9 temporarily. Now, however, I'd like to remove the Fedora installation. I've tried using fdisk from the Fedora 9 rescue mode on the install DVD, but I seemed to merely mess up the cylinder boundaries. When I boot from the DVD, before entering rescue mode it says that /dev/sda contains a looped partition, and asks whether I want to reformat it (completely removing everything on the drive).
How do I remove the "looped" Linux partitions? (I cannot login to Windows, so any GUI applications won't be any help.)
