It would seem that my cds/dvds that I've created under Microsoft vista home premium can't be read/written on (formatted as data disks. Is there a program to be downloaded or an app, that would allow me to read, download or add data to these dcs/dvds. Using ubuntu-10.10 and debian.
View 1 RepliesI went and fdisk'd a USB disk and put the Fat32 filesystem onto it. Then I thought I ran dosfsck over it which I thort formatted the disk - apparently not. Then I copied a bunch of files and directories to it. Now I am unable to recover the files and data. In the rare instances when I perform a sloppy mount I see directories named 001, 002, 003 and 004. These directories variously contain files named 001, 002, 004 (no 003) etc.
Fdisk gives me:

the OS, data and programs are on /dev/sda.
I'd like to copy the full directories and files to the newly added /dev/sdb wich has, as you can see, less space. Also note that /dev/sda has only about 3.6Gigs uses, so it will no doubt easily go into /dev/sdb. How can I do the full copy, and yet make /dev/sdb bootable just like /dev/sda (just as if it was cloned by Ghost)? I've checked dd, but AFAIK, it needs that both source and target devices be the same in size.
Risk to native OS from Live CD?
when booted from linux live cd, all partitions of hard disk become accessible without any restriction. How to block this?
My hard disk is failing and I amnot able to boot into the system! Currently I have logged into the system uing Live CD! Any way to compress and back up the data in my hard disk in an efficient way!
View 6 Replies View RelatedSuppose I have a 80 GB hard disk (sda) with 4GB of contents. Using a dd to copy to a different disk
Code:
dd if=/dev/sda of=/dev/sdb
copies all the contents (including free space). So sdb also needs to be 80GB.
You will notice that in VMWare or VirtualBox disk images, it is possible to set the disk to use only the amount of space of actual data. So a 80GB virtualbox/vmware image with 4GB of contents will be 4GB.
Is it possible to do that with an actual hard disk (sda) image? I want to create an image of an actual hard disk, copy it to DVD and transport it (in mail) for restoration on another computer (having same hard disk).
I'm trying to help out a Windows Vista user by rescuing their data from a failing hard disk. When their laptop stopped booting, I immediately pulled the disk to get as much as I could off of it using another Windows box, but the process took days and ultimately choked on multiple bad sectors and stopped responding. I then hooked it up to my Ubuntu box via a USB disk dock and ran a ddrescue on the Windows partition. The operation took a week, then seemed to get stuck for another week on the "splitting failed blocks" phase. So I have an dd image and a log to go back to, but when I resume that process it still seems to use the disk and I don't see much progress.
I then tried a plain `dd` on the disk with `conv=noerror,sync` options, and that has been running for a few days now, but with input/ouput error messages every few seconds and seemingly no records going in or out. I think that's a bad sign.What's the best, and fastest, way to get the most data off the disk as possible and into an image file, and then perform any necessary operations on the image file so that the disk is no longer needed (since it seems to be just about dead)? Er, just realized I'd put "Windows 7" in the post title, but this is a Vista partition, and I can't change the title. They're pretty similar, with one OS being much less useful than the other, but I thought I'd better acknowledge my mistake.
I have a PC with OpenSuse 11.1. Beside root there are two other users on the system. Now I have installed a new PC with OpenSuse 11.2. Only one user is set up until now. I installed the hard disk from OpenSuse 11.1 into the new PC on IDE Primary Slave, because I wanted to copy some files from the old system. OpenSuse 11.2 has mounted the old disk automatically in /media/disk and /media/disk-1. The problem is that I can't find any files or directories from the users. I could find only one file from root in /media/disk-1/root/Desktop. Why can't I see the files? Does it have anything to do with UID or SUID?

View 3 Replies View RelatedI am using an embedded platform in which I have connected an external harddisk (/dev/sda). The SCSI driver is present and I am using the SG_IO interface for performing the SMART commands with the Hard Disk. (Unfortunately not all the HDIO ioclts are present. So I opted for the SG_IO ioctl). But the data transfer (reading/write data from/to sector) is not working with the SG_IO ioctls. So I searched for some other options. Later in one of the places, I found that we can actually mount the /dev/sda to some mount point in /mnt and then make a XFS file system (mkfs.xfs) of this.
And then we can create the directories and do file operations on this mounted directory. Here the simple read/write systems calls can be used for this. I was thinking about this implementation. But I am confused how I can map the actual LBA (Logical Block Address) to the device file offset. I mean if I want to write to the sector 5, there will be a LBA for it. So I can do lseek on my device and then write the data there. So how the mapping between LBA and device file offset can be calculated.
I want to ensure I have done all I can to configure a system's disks for serious database use. The three areas I know of (any others?) to be concerned about are: I/O size: The database engine and disk's native size should either match, or the database's native I/O size should be a multiple of the disk's native I/O size. DMA: Disks that are capable of Direct Memory Access (eg. IDE) should be configured for it.
Write-caching: When a disk says it has written data persistently, it must be so! No keeping it in cache and lying about it.
I have been looking for information on how to ensure these are so for CentOS and Ubuntu, but can't seem to find anything at all. I want to be able to check these things and change them if needed. The actual hardware involved is very modest. The point is to get the most out of what hardware we do have, even though it's "not very serious hardware" from a broader perspective.
So I have a system that is about 6 years old running Redhat 7.2 that is supporting a very old app that cannot be replaced at the moment. The jbod has 7 Raid1 arrays in it, 6 of which are for database storage and another for the OS storage. We've recently run into some bad slowdowns and drive failures causing nearly a week in downtime. Apparently none of the people involved, including the so-called hardware experts could really shed any light on the matter. Out of curiosity I ran iostat one day for a while and saw numbers similar to below:
[Code]...
Some of these kinda weird me out, especially the disk utilization and the corresponding low data transfer. I'm not a disk IO expert so if there are any gurus out there willing to help explain what it is I'm seeing here. As a side note, the system is back up and running it just runs sluggish and neither the database folks nor the hardware guys can make heads or tails of it. Ive sent them the same graphs from iostat but so far no response.
Just ran into an uncomfortable problem. I usually never save any documents on my machine, and keep all my stuff on an external USB hard disk. (an 80GB TrekStor DS microdisk q.u)
Well yesterday this disk just would not mount.
Read through related posts but nothing seemed to work. Even tried it on a Windows machine.
Tried TestDisk utility. Found nothing wrong with the drive, but still could not repair the MBR.log code...
Palimpsest Utility recognized the drive, but just will not let me do anything with it except format it.
How can i repair the partitions and MBR without losing all my data?

A while ago my harddrive kinda failed. I didnt notice untill I got "Grub error 17" one time when I was trying to boot my computer. The problem is not really that I couldnt log on to my computer, but rather that I have alot of important information on the computer I would hate to lose. At the time I used Ubuntu 8.04 and had reiserfs filesystem on the computer. I bought a new computer and decided to wait untill I could rescue the data before doing to much dmg to it. But I dont really remember if I tried something to fix it before I realised that it was the harddrive and bad sectors that made me get gruberror 17. Hopefully I didnt do anything.
Anyway. Now today I had some extra time, so I decided to dive in. I booted from a linux mint disk and used ddrescue to transfer all the rawdata over the network to an image file laying on an ext4 drive. Once there I used reiserfsck to try and repair the filesystem. After that i mounted the image file and tried to access the files. Thats where the probelms started. I could see the whole treestructure of the harddrive and everything seemed ok, but when i tried to open the files, none of the pictures, documents and so on could be opend, and when I tried to open stuff like MP3 files they played quite strange. Videofiles was really messy, kept changing resolution and was almost always just gray and green squares on the screen. I decided to use ddrescue and move the files from the image file and on to a clean disk. So when I was done I could mount the filesystem on the new disk, but with the same resault, so I did reiserfsck again, and when that didnt help I did a buildtree also. Still with the same resault. So I decided to investigate the data abit. Opening files at random trying to understand what had hapend. And I saw that some MP3 files (the easiest to open) was some kind of mixing between several difrent mp3 files. Some files wasnt even in the same folder, so it was probably just that the file pointer was pointing at the wrong data on the disk. I dont know how that works really, so I dont know how to go on.
So now to the question. How do I get the data back? Have I done something wrong, can I redo somethig? I still have the broken disk and can take data from it once again, but I want to wait to do that untill I really know what to do. I also still have the image file, and the disk with the copied data. I have a ubuntu 9.10 system at my disposal atm.
I've occasionally changed HDD filesystem type in Disk Utility from NTFS to Linux Extended . It created an extended partition containing some other partitions instead of NTFS.

I was dual booting Ubuntu 8.10 and Windows Vista on a Acer Aspire 5920. My laptop went for service and the company said they will give me a fresh laptop instead of the one I am using now for they cannot set it right.
When I plugged in my hard disk through an external cable onto a windows machine it detected only the data present (which is almost negligible in my case) in the vista partition. I would like to transfer all the data I have from hard disk at least the one in the Ubuntu 8.10 to my new laptop on which I plan to run Ubuntu. Can someone guide me on how to go about doing it? Also is it possible to transfer all the installed softwares so that they start running in the new laptop without any extra effort?
I have a simple C program that reads a 1 GB file from disk into memory.The first time I run this program, the process takes several seconds. But if I run this program again immediately after it finishes, the read happens almost instantly. What is going on here?My suspicion is that the operating system is realizing that the data I'm trying to read is still uncorrupted in memory (its been freed but not overwritten), so instead of reading it again, it just gives me the same block. I would really like to know what this process is called, or any Googleable keywords that would allow me to research it.
The reason I ask is because the size of my input data has increased. Now I need to read in a 6 GB file (my system has 12 GB of RAM), but I'm not observing the same behavior with the larger file. Each time I run the program the read takes an equally long time.
I currently have a 2TB qnap nas which will be relegated to mirroring important files from my new nas. I am building up a HP Microserver with 2*2TB and want to look at the best way to manage the data, disks and backups.
My wish list: Power down unused drives
I want all the disks to appear as one.
I want to be able to easily add an extra drive and add to the available space
I want to be able to replace a disk with a larger one and add to the available space (It's ok if I have to manually copy the data from the old drive to the new drive)
If a disk dies I want the remaining disks to still function with whatever data they have left on them.
Email me if a drive dies
If the server blows up then I can plug any drive from the server into another pc and copy the available data off the disk
Mhddfs - anyone use this much? What's the speed like? Do individual drives get spun down if not used? How is it decided which drive gets the data? No one talks about mhddfs much. It all seems to be about mdadm and raid and LVM which I don't think is suitable for my current purpose. I have a existing qnap nas with a total of 2tb that will rsync changed files from the server nightly. To restore missing files would I use rsync in reverse?
i have a portable hdd with ntfs partition, i use it both in ubuntu and in windows.

I am trying to burn mac osx 10.5 install disk from from a 6.7gb dmg disk image. I thought I would be using 2 DVD-R 4.7GB discsfor this burn, I was hoping when the first was full it would ask for another to finish the burn. Instead it get the message that the DVD will not hold the choosen DMG. file.
Can I do anything besides buy a dual layer DVD that would hold the whole file?
So here's what I'm after:
Create Ubuntu inside Virtualbox (done) Join it to the domain using net ads join -S example.com -u admin (done) Update the DNS using net ads dns register (done) Be able to visit the netbios name as defined in smb.conf (lets call it Bob). [Not done]
The problem I am having is that it looks like, even though the machine is now on the AD, and I can browse users in the AD, etc... My network configuration (IP/route tables, etc) are not correct.
For example, my AD server is in the 172 IP range, while BOB is sitting at 10.0.2.15.
The DNS server stores Bob's value as 10.0.2.15, so when I ping it from my workstation at 172, I end up getting no response (obviously it's on a different net).
Bob's route table is configured to deal with 10... range of IP, rather than 172.
I have attempted doing commands such as ifconfig eht0 172.16.1.118 netmask 255.255.255.0 and even editing the route tables, but that then makes outbound network traffic imposable.
I have a dual boot system with Windows 7 and Ubuntu installed on my machine. I use Ubuntu much more often than Windows 7. On Ubuntu I can use LibreOffice Calc, but I'm more used to Microsoft Excel and would like to be able to run it under Ubuntu.

My primary drive is 250GB and has the root, home and var (I'd read it's good to put var on a separate partition for MythTV which I'm planning on doing) on separate partitions. I have a second 1TB drive that I'll be using to backup the 250GB drive and also host less critical data. I've created two partitions on this drive, one 250GB and the other covering the rest of the drive. I'd like to move the Videos directory out of Home on the 250GB onto the 1TB drive but can't find a definitive way of doing this. Should I just follow this guide for moving the home folder to a new partition? Next question is when performing a backup of the 250GB drive how do I make sure it's going to the 250GB partition on the 1TB drive? Can the different partitions be mounted separately?
