Ubuntu Installation :: Installing On External 1tb Disk With 4096 Sector Size?
Dec 9, 2010
In the past I have been able to succesfully install ubuntu on several external usb drives with up to 500gb in size.Now I am trying to install a copy of ubuntu 10.10 on an external usb iomega 1tb eGo drive but I am having major issues.The installer reports the total disk size as only 124 gb, instead of the 998gb that gParted reports for the same disk. Proceeding with "use the full disk" installs ok, but it doesn't boot.Grub2 reports that it cannot find the kernel.After some desperate attempts to repartition and after some googling I think that the issue may be with the sector size, which fdisk -l reports as 4096kb (all my other drivers report 512kb) and I have the impression that linux is not ready for it (or I lack the knowledge, which seems more likely).I have also tried to install fedora 14. This distribution reports the correct disk size, installs properly, but again, it cannot boot (Fedora uses grub, not grub2), with a very similar message to the grub2 installer.Because of the way I work, I need my external usb drive to be able to boot linux. And I find it difficult to believe that linux doesn't handle 4096kb sector disks, so here I am asking for help . Please note I am not a linux expert.

So when i install ubuntu it gets to 47% and than i get this error message. After that the install doesn't really seem to do much.Code:Device /dev/sbd has a logical sector size of 4096. Not all parts of GNU Parted Support this at the moment, and the working code is HIGHLY EXPERIMENTAL.Now i did search and i found another topic where someone had the same problem. His solution was to reburn the CD and try again. I did that and it still got me the same messageP.S. I do have two boot options now however. One for ubuntu and one for windows though i already ran the uninstall.

I'm going to replace damaged HDDs in my server with new drives, which have sector size of 4096 bytes instead of 512. Does CentOS natively support such drives? If yes, since which version? If no, what actions should I take to correctly prepare such a drive to work. How to check that such a drive is correctly recognized by OS?

I'm a Ubuntu 9.10 user and have baught a WD 1.5TB HDD. When just formating it with gparted it's extreemly slow! I have read that with gparted 0.51 there are ways to get this harddrive to work correct but there are no 0.51 packages available for 9.10.

Gparted won't let me install Ubuntu 9.10 64 bit. Every time it hangs at 47% and throws a sector size error, something like: doesn't support sector size 2048 and the code is HIGHLY EXPERIMENTAL. My 1TB hard drive exists out of the following partitions:
100MB Windows 7 Reserved
900GB+ Windows 7
30GB EXT4
1MB unallocated space
Is there a workaround for this? I've tried installing Linux Mint and Ubuntu but both gave me the same error.

I want to find out how many 4096 byte blocks there are on my disk. I used df -B 4096 and it gave me a number but I'm not sure it's correct as I can use dd to read past what should be the final block.
So I do df -B 4096 and it reports this result:
Code:
Filesystem 4K-blocks Used Available Use% Mounted on
/dev/sda1 15618840 13190294 1635137 89% /
But when I use dd to go past that block, it doesn't report an error or anything. The command I'm using is
Code:
dd if=/dev/sda1 bs=4096 count=1 skip=15618841
How can I know that I'm really reading the very last block on the drive?

It's many years since introducing of installation of Linux live CDs like Ubuntu from USB flash drives. I never been able to use such services on my 2GB KingStone flash drive, because it's sector size is 2048 and the famous linux error: "Not all ... support more than 512B sector size". Although I formatted my flash drive many times and even erased the whole partition table and cleared all flash contents with 0xFF values but it still has sector size of 2048.I want to know where the hell those softwares like "USB Startup Disk Creator" in ubuntu and kubuntu and fdisk in almost all linux distro's get to know that the sector size is 2048?

I was attempting to reformat a 16GB MicroSD card in my camera when the battery died mid-way. After that, any time I try to read the card in my camera, it gives me a "Card Error" and does not allow me to reformat it in my camera.
So, I thought I would plug the camera in to the laptop with it set to host the card as media when plugged in as USB, in an attempt to fix the formatting issue.
However, when I plug it in to my linux machine, it does not register as a device (e.g., /dev/sda) due to some errors, therefore I cannot reformat it. Essentially, I think I need to fix the partition table but I'm not sure how to when it doesn't register as a device. code...

I've recently brought a Western Digital Elements 2TB external hard disk and have been planning to encrypt it for use as a backup drive. However, it seems that these 2TB disks use the new 4K sector sizes and thus need to be handled more carefully than the older 512K ones.
After spending a week looking on Google, I have to admit I'm pretty confused and hope somebody here might be able to verify my conclusions
The drive reports that it's a 512-sector drive which is probably false. Using fdisk -uc, the original partition starts at sector 2048 so I assume that is a valid sector also to start a dm-crypt partition overwriting the previous one?
I've also read that every layer that is added to these drives must support the 4k layer. That means both dm-crypt and the ext3 filesystem I intend to put it on have to do so also.
Looking through the cryptsetup document, it states under the option "--align-payload" the following:
"Align payload at a boundary of value 512-byte sectors. This option is relevant for luksFormat. If your block device lives on a RAID, it is useful to align the filesystem at full stripe boundaries so it can take advantage of the RAIDs geometry. See for instance the sunit and swidth options in the mkfs.xfs manual page. By default, the payload is aligned at an 8 sector (4096 byte) boundary."
The fact that the payload is aligned at 4096 seems to indicate to me that it should be fine using default settings. Does everybody agree with this? Or do I need to take special measures due to the dm-crypt headers?
When I later finish up the dm-crypt layer, then I need to put ext3 on it. I understand adding -b 4096 to the mkfs.ext3 command will resolve that. Is that also correct and will it work well in combination with the dm-crypt layer?

I have xp/fc8 on an older ide drive and just installed a new sata 1T and planned to put fc10 on it but in the process I killed my fc8 installation. I told the installer that the other disks were off limits but it was somewhat confusing at the bootloader page. So, I suspect that I told it boot off the fc8 disk. If that is the case is there a way to restore the fc8 install by somehow rescuing the /boot partition on the fc8 disk?

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.

I have a small project that I am trying to do for my job to help us out. Basically, I need to make a tool that lets me view all the sectors of a hard drive in hexadecimal format to make sure they are all zero after a low-level format. I need it to be very minimal, and display the data in a way that I can scroll down and skim through the sectors. Doesn't have to be pretty, just functional.I need it to do more things down the road, but this is the first hurdle I need to overcome. I would like to create a GUI interface so it looks nice, but first I am only concerned with the sector viewing function. I am not entirely sure where I should start.
I see there is a tool called dd I could use to read the hard drive and I am wondering if I need to use that, or if I can just open /dev/hda as a file and be able to view all the sectors that way.Also, just to clarify, I am wanting to write this tool for linux,specifically DSL. I need it to be a very small distribution that can be loaded quickly from a usb drive, cd, or over the network with PXE.

I want to create several virtual machines based on a minimal (no GUI) Ubuntu installation. I'm using VirtualBox (on Windows 7), the VMs are being created with 256MB RAM and using the Ubuntu Minimal CD Image [URL]. Because I want 4-5 of these virtual machines I want to use minimal disk space for storage too, which means restricting the virtual hard disk size for each. My first attempt was to limit it to 300MB, but when I got to the partitioning section of the installer it would not allow me to do automatic partitioning and forced me to do manual partitioning, it did moan about the size of the disk.
So I started again with a 1GB virtual hard disk, this time the installer was quite happy to do the automatic partitioning. My question is how small can I make my virtual hard disk without having to do manual partitioning? I don't have a problem with doing the partitioning manually but for easiness I just want to do it automatically and find it strange the acceptable size isn't mentioned anywhere (that I could find).

a client brought in an 160GB external HDD and wanted to get the files off it, there appeared to be no partitions on the disk but i thought it may have been formatted to use the whole disk. I tried to mount it as the various FS types the client thought it may have been to no avail.
I ran testdisk on it which told me that it previously had a mac partition table and a 210GB partition on it (which is larger than the disk) could anyone enlighten me as to whether or not this is even possible, and if so how could i retrieve the data?

I have three disk in my system. One SATA (250GB) and two SCSI (73GB) disks. The Two SCSI disks were installed originally and RHEL3 is installed on it. The SATA disk is installed a few years later with RHEL5. As you can see below, the boot sector is still on one of the SCSI disks (sdb1).
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 236545184 15259760 209075624 7% /
/dev/sdc2 68539636 4578792 60479160 8% /users
/dev/sdb1 101089 26847 69023 29% /boot
/dev/sdb3 68437272 36963704 27997104 57% /RHEL3U7
tmpfs 2025916 652 2025264 1% /dev/shm
How I can move the boot sector from the SCSI disk (sdb) to the SATA disk (sda) without losing data and without re-installation?

2 months ago, I built a dedicated backup server using 4 2TB SATA drives for software RAID5 (6TB total). A few days ago, smartd sent out mail saying it found an unreadable sector on one of the drives. I ran selftest using smartctl and the error persisted. So far, neither software RAID nor ext4fs running on top of the RAID volume have reported errors.
MOST OPTIMISTIC: It is normal to have a few bad sectors among billions. Software RAID takes care of alternatives. Keep using the system until RAID spits a more serious warning in the future.
MOST PESSIMISTIC: It is a really bad sign to lead a disaster. No good disk drive should have bad sectors especially when it is only 2 months old. The error is simply not detected by software RAID and ext4. Replace the drive immediately and return the bad drive to the supplier.

Should the first bootable partition start from sector 1 on a hard disk? or Can it be created anywhere on the disk? I am using fdisk to create the bootable partition.

im installing ubuntu and after I reach the partioning portion there's a prompt that says "before you select a new partition size, any previous changes have to be written to disk. you cannot undo this operation.Please note that the resize operation may take a long time.
Go Back Continue
after i click continue there's a prompt again saying
"too small size"
ok
then after i click ok it will go back to the partioning portion again.
im dual booting xp and ubuntu and there's a 30 gb on my drive C 16.4G is still unused.

I recently installed Bio-Linux 5.0 as a dual boot system with XP for some bioinformatics applications, but Im having some problems with the amount of disk space which can be allocated specifically for the Ubuntu install.
I partitioned a 250 GB portable hard drive into:
/dev/sdb1: 154.76 GiB (with 30 GiB allocated for Ubuntu)
/dev/sdb2 : 78.13 GiB
Ive been using blastclust to analyse some very large data sets, which keeps on crashing due to filesystem running out of disk space.
When I installed Bio-Linux 5.0 from the live cd, the maximum size I could allocate to the install was 30 GiB, and I havent been able to find a way to change this.
Ive tried using System->Administration->Partition Editor using the live cd, and can view / delete the partitions, but I cant find a way to specifically alter the disk space allocation for Ubuntu.
How do I increase the filesystem size to larger than the current 30 GiB?

I've 2 computers (one at the job, one at home), different motherboard types but same chipset, having AM2 AMD CPUs but different clock speed. I don't have (I don't want to buy) internal hard disks for these computers.
I would like to buy one external USB HDD and install the latest Ubuntu. I will carry this HDD to my job and my home. Is it possible to use this HDD as boot HDD on both computer? Even they are not same just similar? Is this a problem for Ubuntu?

I want to add Fedora 14 to my triplecore 3GB RAM computer which has windows, Fedora 12 & ubuntu installed. What are the recommendation (e.g. size) for harddisk partition allocation? I can reuse the swap partition, can't I? Should I install Fedora 14 to a single partition (ie. /)? Should I use only ext4?

Is there any hope of getting a WD10EARS 4k-sector disk to work properly as a secondary under Etch? Just wondered if anyone had a fix before I RMA and return it as "Not suitable for purpose" WD say it should be OK with linux. But it ain't. It gives very poor perfromance, with a lot of hesitation. The issue is apparently one of sector boundaries, but the exact details are extremely complex.

I want to install Ubuntu onto a partition on my external hard drive, but my CD burner is broken so I can't just boot up with a live CD and do it that way. So can I install Ubuntu onto my external hard drive with the Startup Disk Creator that comes installed on Ubuntu? And if not is there another way I can do this?

I recently upgraded to 10.04 and during the upgrade process my external hard disk was plugged in. Now everytime I boot up ubuntu informs me that sdb1 is missing and wont boot up till I ask it to "skip" waiting for it. Also I am assuming because of this I have trouble mounting any other external hard disk other than my own, keeps giving some sort of unable to mount problem

I am trying to install 10.04 to an external HD (not flash). I ran the live CD, installed to it and all seemed to work fine, but I don't want to use GRUB. I ran 7 repair and did a bootrec /fixmbr and it's booting normal, but I can't boot to USB.I want it to boot normal, unless I hit F12 to boot to removable device. Not much of a Linux person, but I am trying to be.

I really need some help here. I was installing Ubuntu 11.04 supposedly on a Desktop but I had my external hard disk connected via USB. This external hard disk had two NTFS partitions with lots of important personal and my works.
I accidentally installed Ubuntu upon it and I believe I had created new Linux partition for the Ubuntu installation. Is there any way to undo everything?
