I would like to fix partition alignment on my SSD disk, and I am curious if it is possible to do it without handling data from disk and back. Is it possible with Gparted?Quote:
$ sudo fdisk -l /dev/sda
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
[code]....
I am trying to install ubuntu 9.10 on an system which already has XP installed. I had used Ubuntu earlier but when I installed XP ( in an attempt to dual boot) I seem to have lost the Ubuntu Installation. But the problem is GParted or the Ubuntu installer dont recognize the existing partitions but instead see it as an empty unallocated drive. I have a 120GB hard disk. Below is the extract after fdisk:
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x4fa8a60b

Also this is how the disk Utility in Ubuntu sees my system: ( See attachment)

I have a 120GB HDD with a 22GB partition for Ubuntu and the rest for Windows XP. Windows finally died on me so I attempted a fresh install on its partition. However, the install threw a ton of errors so I used a LiveCD to re-install Grub and I booted into Ubuntu. I open up the disk utility to re-format the Windows partition so I can re-try re-installing Windows, but immediately I notice that the partitions are not right. If you add up all the partitions, they are about, say, 18 million terabytes over my HDD's 120GB capacity. Ahhh! What do I do?
I don't think anything is terribly altered, since I can still boot into Ubuntu, but I am completely confused and slightly worried that I might kill any chances to save my HDD I can't post a screenshot due to my post count, so the image loses some of its efficacy in making it small enough for an attachment. Here is the output of fdisk -l: Code: omitting empty partition (5)

This is the third 9.10 install to do this on two different laptops, so wondering what's up...
In both cases, the goal was to leave a large chunk of unpartitioned disk after the Ubuntu partitions, for a second OS install or a filesystem Ubuntu cannot create like NTFS.
When I install with manual partitions, the system can't boot and asks for me to insert a system disk and press any key. When I reinstall telling Ubuntu to "use the entire disk" it then works.
First laptop, first try:
Remainder of the 500GB disk is free space.
Fails to boot, "insert system disk".
First laptop, second try without the /boot partition:
Remainder of the 500GB disk is free space.
Fails to boot, "insert system disk".
"use entire disk" works perfectly.
Second laptop, first try:
Same thing, non-system disk or disk error, insert system disk.
Second try "use entire disk" is currently in progress but I expect the same to happen.
The partition is formatted to ext3, starting with block 1 on the drive. The mount point for /dev/sdc1 lists 0 files when doing `ls -A` `df -h` shows that the partition has 92MB used. How is this space being used, and how can I free it up?edit: I guess this isn't a newbie question.
View 7 Replies View RelatedI have a PC with Windows 2000 Pro installed in an NTFS partition of 60GB. My rest hard disk (500GB) is empty, no partition at all. When I run Ubuntu 10.04 installation after step number 3 I get a weird step number 4 showing prepare partitions with an empty array and no available command button at the bottom! So I can not create any partition... Also in step 4 I never see the "prepare disk space" menu. If I use a 9.04 Ubuntu CD and I try to install I get every menu fine as expected. I even tried the 10.04 CD to another PC with Windows XP PRO and the installer worked as expected for partitions.

I've tried Unetbootin but that only copies a few megabytes of files - the rest of the image data in the ISO is ignored.
I have verified the ISO is valid and working with VirtualBox. It's MD5 hash is also as expected. But I need to boot at the real bios not an emulated one.
I've also tried things like:
sudo cat /disk/image.iso > /dev/sdb1
and that got "Permission denied" -
Just ran into a problem involving mdadm, a disk which had been in a raid array, and an attempt to reformat. Basically, I went to reformat some partitions which had been in raid, and one of them threw the error andy@andy-desktop:~$ sudo mkfs.ext3 /dev/sdb5 mke2fs 1.41.11 (14-Mar-2010) /dev/sdb5 is apparently in use by the system; will not make a filesystem here! An attempt to umount revealed it was not mounted. lvdisplay and fuser did not reveal anything to me, so I just started looking around. I was graphically navigating /dev and noticed a /dev/md_d0 which did not look like /dev/md_d1 etc (it was missing a little arrow). I had not seen this notation before (my raid was md0), but figured it couldn't hurt to try stopping it.
andy@andy-desktop:~$ sudo mdadm --detail /dev/md_d0
mdadm: md device /dev/md_d0 does not appear to be active.
andy@andy-desktop:~$ sudo mdadm --stop /dev/md_d0
mdadm: stopped /dev/md_d0
After this, the partition formatted fine! I saw a lot of instructions including zeroing the partition and removing a logical volume, but the above was the only thing which worked for me! Just posted it in case it helps someone else. I know I've not been terribly technical!
I've been getting this error message:"The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator."a few times, and it turns out to be because of low disk space. No worry, I empty the trash uninstall unneeded programs and clean out the downloads folder that filled up my disk. And all is ok. But not this time.Since I can't use X, I delete stuff from the terminal, and also make sure to clean out the .Trash in both /home and /root. But still the disk is full. I delete more stuff, but it doesn't even seem to go to .Trash. It disappears, but no more disk space.

View 4 Replies View RelatedI have a 160Gb Hard drive with 3 partitions. sda1, sda2, sda3. sda1 & 2 are just under 20 GB each. the other 120 GB is free space. I have so many 40GB hard drives! I would like to copy (with dd) the MBR, sda1 & 2 to a 40GB hard drive and be able to just use that so I can free up my 160GB hard drives. Typically when I want to clone something, the drives are equal or larger than the original. I'm not too sure about this, and if I use code (show below), will I also get the MBR? #where sda is the 160gb with 3 partitions and drive sdb is a 40GB drive with 2 partitions.
Code:
dd if=/dev/sda1 of=sdb1
dd if=/dev/sda1 of=sdb1
Also, is there a way I can do this with 1 line, or have both dd operations running simultaneously?
Something 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:
And here comes the extended partition:
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:
And, here is my slightly modified sfdisk table dump:
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.
I got a 40GB seagate HDD which has got through some unsuccessful windows and linux installations and now all the partition tables are corrupted... I tried to format with System>Administration>DiskUtility but it gives this error when I'm do: Error creating partition table: helper exited with exit code 1: Error calling fsync(2) on /dev/sdb: Input/output error gParted was not even useful since it didn't not even detected the drive...
Isn't there any simple way to format the crap from the Ubuntu 10.04 Live CD? I believe that on windows, there wouldn't be that problem since the "format c:" crap just format the drive without asking questions. All I want to do is to format the drive so I can create partitions later. Also, I have only access to the live CD and I don't have any Diskette drive installed.. I believe we now live in a world where this crap isn't needed to fix a computer.
I am installing 10.10 on my PC. I have changed the hardware and the previous install was for a x64 I now have x32. I ran the live disk and have selected install. I am now on the partition page, (manual). I am happy with the concept of partitioning and which partition is which, but I can only change the linux partition. At the moment I have @60G NTFS, 1G swap and @18G Linux. I want to reduce linux partition to about 12G (which is fine I've done that) I now have free space. I want to increase the swap partition to 2G and the remainder to be added to the NTFS partition. However, I can't add any more disk space to the latter partitions. The Swap partition has the space bar available, but the increase is greyed out and on the NTFS partition, there is no option at all.

Unfortunately it's on the outer edges of the disk in an extended partition.
This has always bugged me, with regards to read/write performance.
Do my concerns of reduced performance have any foundation? Should i bite the bullet and format the drive installing ubuntu first?
I ran the disk read benchmark and my read speeds were 100MB/Sec at the beginning of the test to just 55MB/Sec at the end. I have no idea if the position of the test has any bearing on the position of the disk or whether the speed recorded is affected by other factors such as the tests function or simulation.
I want to make the transition from windows (sick of it). Im using Lenovo G530 Laptop and was wondering which would be the best Linux Os (meaning Ubuntu, fedora or something else). Keep in mind that I mostly use my laptop for college work and a lot of video and audio editing. I also want to be able to run Dual operating system (meaning that I wanna run both Linux and Windows) from the same computer as it might be easier for me to make the transition a little bit more easier. That being said I need someone to give me tutorials (video preferred) on how to make the partitions on the hard disk and step by step instruction on how to install both the two OS in my laptop.
View 3 Replies View RelatedI was on Ubuntu 10.04 I used the Disk Utility to edit the partitions.
Here is the table it's showing:
Here I deleted 79 GB patition from FAT32 to NTFS and deleted 50 GB space that was ext4 partition where SUSE was residing the bootloader was of SUSE that was working using the same utility.
After that with a live cd of ubuntu I tried to recover the grub but there was no device.map file. Later I found the partition table absent.
The utility shows above table but Gparted shows only 500GB free space without any partition. Please help can't loose all the data.
I can access the partitions in live environment I can't even install a fresh OS because It also shows 500GB unallocated space.

I don't want to break MYSQL and I don't want to be down for a long period. I have heard of some people suggesting a sym link to a /newvar and /newuser on sdb but I have also read this will not work when moving to a different physical drive.
View 3 Replies View RelatedI got a new hard drive yesterday, a Seagate Baracuda XT 2000GB SATA3. I'm running it on the SATA3 jmicron chip in AHCI mode, and Opensuse 11.2 is having issues with using this hard drive properly.
The hard drive seems to take a while to detect, for one thing. After it is detected however, I am told I have no hard disk that can be used for installation. The exact message is:
"No hard disks were found for the installation. Please check your hardware!"
After that, I'm told the partitioner can't read the partitions on my hard drive properly:
"The partitioning on disk /dev/sda is not readable by the partitioning tool parted, which is used to change the partition table.
You can use the partitions on disk /dev/sda as they are. You can format them and assign mount points to them, but you cannot add, edit, resize, or rename partitions from that disk with this tool."
I partitioned the new hard drive under Windows, with a partitioning tool called Partition Wizard (free / home version). I'm not sure if hard drives partitioned with this tool are not recognized by OpenSuse's partitioner, or if it's something else.
I already installed Windows on this hard drive, so I can't delete all the partitions I have so far and start all over again (I'm keeping my system a dual-boot between Windows 7 and openSuse 11.2). What can I do so OpenSuse will see and modify my partitions? If it is the partitioning not being understood, is there some sort of tool that can make the partition table of the hard disk linux-readable? (a free Windows program that could do such).
I have what seems to be a hard disk Write speed problems with my first hard drive. Timing the cp command of a 700 Meg file takes about 8 secs from disk 2 to 3 but takes 25 minutes from disk 2 to disk 1.
Here are the details:
Kubuntu 9.04 (Kernel 2.6.28-15-generic)
Hard Disk 1 : /dev/sda (WDC WD2500KS-00MJB0)
Partitioned
/dev/sda1 ext3 / 10 Gigs
/dev/sda2 extended 222 Gigs
/dev/sda5 linux-swap 2 Gigs
/dev/sda6 ext /home 220 Gigs
Hard Disk 2 : /dev/sdb (WDC WD2500AAKS-00F0A0)
Partitioned :
/dev/sdb1 ntfs 16 gigs
/dev/sdb2 xfs /home/eric/data_drive 216 Gigs
Hard Disk 2 : /dev/sdc (ST3500320AS)
Partitioned:
/dev/sdc1 xfs /home/eric/data_drive2 465 Gigs
By doing 'time cp ...sdb1/test.avi ...sdc1' takes about 8 seconds and same vice-versa. the command 'time cp ...sdb1/test.avi ...sdb1/test1.avi takes about 11 seconds and the same holds true if sdc1 is used But copy sdb1 or sdc1/test.avi to either sda1 or sda6 and it takes 25 minutes. Same problem if I copy from the same drive partition (sda). I have booted a livecd Knoppix 6.2 and the same problems happens.. So safe to say it's not Kubuntu. The only thing that is left to do is backup and reformat the partitions as XFS and try again. I also did a full smartcontrol Extended test and no errors. Checked all the various logs and nothing found.
I just bought a new 2 TB hard disk to replace my old 175 gig one. I currently am dual-booting Lucid Lynx and Windows 7, and rather than go through the process of reinstalling both, then reinstalling all my programs, settings, and everything, I was wondering if there's a way I can just copy the partitions on my 175 GB disk to the new one, grow them to fill up the rest of the free space on the new 2 TB disk, and then plug that HD into the primary master plug on my motherboard... will that work?

From within Linux, what's the most risk-free way of imaging these two partitions and saving them to a single image file or archive? I want to preserve the entire partition because I have no idea what I may have forgotten to copy. What is the most suitable program that can do this?
Is there any way to run the partition in a virtual machine at a later date?
After this is done, I want to delete those old partitions and extend my Linux ones.

View 1 Replies View RelatedI have 2 hdd
lvm was created in 2nd partition type primary.
yesterday i had deleted all partitions in the first drive of windows only from ubuntu disk utility. today i went to install windows and the partition space was shown as [139gb] , i thought this is the first hard disk. But my guess is windows must have taken the free space on my home partition inside lvm[ 150gb which roughly translates to 139 GiB.
SO first i deleted the whole partition of 139gb which was shown different in unallocated space as a slight less figure and then i created a 30gb partition on that space shown and went ahead, windows post creation again showed 139gb and then gave a message on next window that partition does not contain data to install windows xp. Strange i thought, this becoz next screen before the format partition as ntfs is all to be shown. Then i just felt something fishy and rebooted and then ubuntu of 2nd hdd is not booting.
I ran test disk from gparted live cd and i find td recovered the boot drive but not the 2nd primary partition in which lvm [root,home,swap] is created. It shows the lvm as 279gb. But not the 3 logical partitions inside it.
Now when i boot post the grub menu i get the following message
This disk contains all my data and the first drive was also wiped out full. test disk is not able to get anything on that windows drive.........
I will be installing Ubuntu Server 10.04 LTS. The partitioning install section is text based and IMO a bit cryptic. I was wondering: Can I first set up my partitions with Gparted live disk and then pop-in the server install disk and install using the partition structure I made with GParted?

View 2 Replies View RelatedI have a Centos 5.5 system that had 2 primary partitions (2nd is setup as LVM with multiple LVM partitions) and then installed Windows 7 as Dual Boot.
However, Windows 7 has installed a 200MB system partition which is GPT/EFI as partition 3 and the Win7 OS as a Primary Partition.
I have a heap of space undefined after this fourth primary partition.
However, as 4 primary partitions have been used, I can no longer create an extended partition to utilise this.
As such I would like to know what is the best and safest way to proceed, and if possible step by steps instructions for the best option eg:
1. Delete the Windows 7 System Partition and create the extended partition (I expect this will prevent Windows from booting)
2. Use something like partition magic to change the Win 7 OS Partition 4 to an extended partition (Not sure if this will work)
3. Make changes to the overall system including both Linux and Windows so that it will use GPT only (I have
had no experience with GPT so this is a bit scary)
4. Other?
I've a faulty hard disk I'm trying to read data from before I send it to the professionals. The disk makes some "good" mechanical noise when plugged into an IDE-USB header into my machine, so I think it's spinning up OK.
Under Windows, the disk is seen in admin tools but I can't do anything to it; it's unreadable and unalterable.
Under Linux (Ubuntu), I see the sdb appear in /dev. No partitions though (no sdb0 etc). At first, I thought this implied that my MBR was bad and the partitions could not be found. But, using dd suggests it's a little worse that:
