mistakenly copied an iso into external hard drive using dd

vecciora — Mon, 04 Feb 2013 02:51:00 -0500

I was mistakenly copied an iso into my external hard drive!

# dd if=iso.iso of=/dev/sdb oflag=direct bs=1M
^C83+0 records in
82+0 records out
85983232 bytes (86 MB) copied, 2.34214 s, 36.7 MB/s

It's not finished though. Hurriedly pressed ctrl+c to stop it. I could still play videos in my external hard drive but I'm worried. Is it okay? Or not? What should I do?

A clip of fdisk -l output:

Disk /dev/sdb: 250.1 GB, 250059350016 bytes
64 heads, 32 sectors/track, 238475 cylinders, total 488397168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x127a3aba

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           0     6047743     3023872   17  Hidden HPFS/NTFS

Sorry for my bad english.

How to start raid array at startup

Phenom — Mon, 23 Aug 2010 02:17:23 -0400

I added a raid drive to my computer and created an entry in /etc/fstab to mount it. The problem is that it doesn't mount at startup. I have to go into System->Administration->Disk Utility. From there I have to start the raid array. Then I can mount it. How can I make it automatically mount at startup?

Partitioning Troubles - Resize Operation Has Been Aborted

resuni — Tue, 08 Jun 2010 22:44:36 -0400

I just upgraded to Ubuntu 10.04 and hate it. I'm having many problems with networking and a few other things. Instead of figuring out all the problems I'm having with Karmic, I decided to go back to Jaunty which actually worked for me. But I have no way of backing up all my data before reinstall. I realised I was only using ~30% of my hard drive so I decided to partition my hard drive in half and install Jaunty on the second partition. Then I could transfer all my data from the first partition to the second then erase the first and repartition again to get the Jaunty installation to fill up the entire drive. Here's where I'm having the problems:

I wrote an Ubuntu Jaunty image file to my flash drive and booted from it. So far so good. I select Install Ubuntu from that first menu that comes up. I go through the time zone and keyboard layout settings. All that works. Then I get to the screen entitled Prepare Disk Space. It tells me I have Ubuntu 10.04 installed and it asks me where I want to put Ubuntu 9.04. I select Install them side by side, choosing between them each startup and click Forward. I then get an error:

Error informing the kernel about modifications to partition /dev/sda5 -- Device or resource busy. This means Linux won't know about any changes you made to /dev/sda5 until you reboot -- so you shouldn't mount it or use it in any way before rebooting.

I click Ignore and a window comes up entitled Please wait... and it stays there for a while. Then I get another error that says:

An error occurred while writing the changes to the storage devices.

The resize operation has been aborted.

I click OK and it brings me to a screen where I can edit partition tables. I select the /dev/sda1 partition and click the Edit Partition button. A window comes up. When I change the New partition size field, will it keep the old Ubuntu 10.04 data in that partition and only resize it or will it format the partition as well? Also - why isn't the easier side-by-side technique working? Any help as to how I can do this is greatly appreciated.

What are the default partition names when installing Linux? Is it the same for Ubuntu?

Reading/Writing from/to a partition from Linux and Windows

carleeto — Sun, 09 May 2010 21:45:39 -0400

Here's the use case: I dual boot Windows and Linux. There are heaps of files that I share between them (one example would be about 65GB of snaps). I therefore need a partition that at the very minimum:

Linux can read and write
Windows can read

Ideally, I'd like both OSes to be able to read and write to it. Obviously, this depends on how I format the partition. I'm currently using NTFS.

So, does anyone know of an alternative way of doing it? Speed is not a concern. Accessibility of the data is. Secondary to that is the best possible use of the available space.

Options I've already tried:

An ext3 parition with ext2fsd on Windows. Not good enough because I've had BSODs while trying to copy heaps of folders simultaneously
Multiple FAT32 partitions. NTFS is better.
