General :: Accessing Secondary Hard Drive With Knoppix
Apr 5, 2011
I am working on a computer that the hard drive crashed. Inititially they had a virus, reloaded windows, and had the computer up and running. When downloading software it crashed and will not boot. I have tried all the numerous routine fixes with no success including using the repair discs. The repair discs no longer work and they are unable to get a second set. As a last resort I am able to access the hard drive when booting from Knoppix from a CD. There are a couple things I would like to try from Knoppix, but do not know if it is possible. First, Is it possible to load the boot files from knoppix? Second, can you roll back the drivers from knoppix?

I have been running a computer under Windows XP for years, and recently it stopped booting unexpectedly. It tries to load windows, but partway though loading a BSOD flashes and it shuts down. To remedy this and hopefully fix this, my frined lent me some Knoppix CDs that I could boot from. He also lent me some external hard drives. I want to be able to access my files on my old hard drive.
Here's the problem: (in Knoppix 6) When I try to mount my main partition of my hard drive, which shows as sda2 (sda1 is an old recovery partition left over from when I ran vista), the following message pops up: "A job is pending on dev/sda2" A little later another error window pops up: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." I want to be able to mount my hard drive in Knoppix 6.

I have a secondary drive on my new RedHat Linux computer and I want to make it permanently accessible from the RedHat system that is now running on the computer.
It is an old Windows NTFS drive that was a secondary drive when this was a Windows machine.
What do I need to do to, and how do I do it:
1) Format it into a format that Linux uses.
2) After it is formatted correctly, permanently mount it so it will always be accessible
3) After it is successfully formatted and mounted, how do I access it? (For example, to add a new ascii text file to it via 'cp')

Having just moved to Linux from Windows, I have never considered whether or not to partition my 250 GB external hard drive. As of right now it will only be used for data storage. Should it be partitioned? If so, what size partitions?

I've read the official documentation regarding hard drives and partitions. My pc has two hard drives. a 160gb primary hard drive with windows 7 a 1.5 tb secondary hard drive with about 80gb of free space I would like to know whether I can install ubuntu on the secondary hard drive, without touching any of the data present on that drive. From my limited understanding of storage, files are written all over hard drives during copy, move etc... Is the ubuntu partition manager smart enough not to overwrite any files during installation? Will I get a warning if there is a risk of any data loss on the secondary hard drive? I cannot backup any of the data on the secondary hard drive due to all my external drives currently being full.

I have set up VNC on my Centos5 Server via the instructions here:
[URL]
I am able to log in via VNC through a browser (on my Window laptop), however when I try to access my USB hard drive on the Centos Server, it says:
Error org.freedesktop.DBus.Error.AccessDenied
Does anyone know of any step by step instructions so that I can be able to access my USB Hard drive?
I have found a few posts on the internet about this, however the fixes are either vague/hard to understand etc?

I have Ubuntu 10.10 on my USB stick, and it boots fine. I want to be able to use the PC's hard drive, though, for storage of my files. My PC has WinXP on it and I dont want to lose it either. Is there any way by which I can mount the hard drive whenever I boot using the USB stick so that I can use it for storage?

I have a network where several machines are connected through a switch. I'd like all machines to be able to read/write to/from the hard drives of the other machines. for example:
machine1 will read/write files that are on the hard drive of machine2
machine2 will read/write files that are on the hard drive of machine1
machine3 will read/write files that are on the hard drive of machine1
machine3 will read/write files that are on the hard drive of machine2
etc etc...
all of this reading/writing will be done through the terminal, and programatically. rather than SSHing into a machine to read/write files from it, I'd be happy to set up some 'conventions' on how to access hard drives of various machines. for example:
'hdd1' will refer to the hard drive of machine1 (that has the static IP of 192.168.0.1).
'hdd2' will refer to the hard drive of machine1 (that has the static IP of 192.168.0.2).
'hdd3' will refer to the hard drive of machine1 (that has the static IP of 192.168.0.3).
etc etc...
this way, when I want to read/write a file, its PATH will be something like ~/hdd1/myfile.txt; ~/hdd2/anotherfile.txt;

At first I thought it was the daily cron jobs, but it's been at it for like 3 or 4 hours. It's driving me crazy locking up my system. I suppose I should get off the computer anyway, no real reason to be on for so long.
The only things that look weird in system monitor is kwin, virtuoso-t and X seems to be higher CPU usage than it should. And CPU usage is 20-50% when I'm not doing anything. It was indexing my files.

A year ago I put some stuff on my external hard drive and now I'd like to retrieve it. I've upgraded through a couple of versions of Ubuntu since then and now it doesn't work. I saw that this is a frequent problem in the forums but couldn't find a solution.
How I can access my drive?

when I load into Ubuntu 11.04 from my USB drive, why can't I access the files on my internal hard drive? I mount the drive but I cannot see any of the music, videos or documents contained on that drive (which is also an Ubuntu 11.04 drive). I was wondering so I could copy those files onto my external hard drive and reinstall since my Ubuntu crashed.

I would like to access my NSA-220 Plus through the Internet without having computer turned on. I tried to set it up as a FTP server but I was not successful. I tried few tutorials but all allow me to access NSA-220 Plus only within my home network which is not what I want. Also I tried user manual which does not really tell you how to do this.

I'm trying to implement laptop_mode (to put disk to sleep when not in use), but something keeps waking it up. 'TOP' really doesn't do the trick.
This is apparently a known problem. Has to do with disk idling not implemented correctly.

The hard drive is accessed every few seconds with OpenSUSE and when it is there is a click sound when it is first accessed. I have other distros which dont make the clicking sound when they access the hard drive. I need to prevent opensuse from making the click sound when it does whatever it's doing. Im not even sure what it's doing or what settings to change, and most importantly how do i make it not click? Maybe i could copy settings over from another distro if i knew which settings to replace.

I have a machine acting as a gateway for a private network. While it can ping hosts on that private network, I can't use samba (smbclient or smbmount) to access shares on hosts on the private network from that machine. Other machines on the private network can access shares on other machines - just not the gateway server.
Here's how the gateway is configured:
When I try to connect to ports 139 or 445 (via smbclient or smbmount) the mount() system call times out. As I mentioned above, I can ping those hosts, so UDP packets work but TCP packets seem to get blocked or lost.

I'm pensioning off my 10-years-old home server and replacing it with an Ubuntu 10.04 box. The two storage devices are a Western Digital Caviar Green 2.0TB HD and an Intel X25-M 34nm Gen 2 80GB SATA II 2.5inch SSD (the box has 8GB RAM and an i5 750, if it matters).
I don't care much about boot times (since I don't plan to reboot all that often;-); the main frequent, performance-demanding task will be (re)building large open source C or C++ software packages from sources (as an open source contributor, I do that often).
So, I thought I'd keep the SSD as the secondary drive and the HD as the primary one, using the SSD mostly for the files that can otherwise demand a lot of seeking (esp. in a parallel make).
However, the friendly vendor (perhaps more experienced in Windows systems than in Linux ones) thinks the "normal" way to configure the machine would be with the SSD as the primary drive. I'm pretty rusty on configuring and tuning systems, so, I thought I'd better double check on SuperUser.

My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.

I am noticing problems accessing the firewall gui and mounting the second hard drive in my PC running Fedora 13. This is only when I am accessing the machine with VNC. If I am sitting in front of the physical machine, I have no problems at all. I would like VNC to behave more like I am sitting in front of the computer. Is there a way to do this? Thank you in advance for your feedback.

I am developing a program which can access the SATA-hard disk. I have to use the /dev/sda interface for accessing the hard disk. What are all the commands i can use to perform the sector read, write (Both DMA and PIO), sending the smart commands etc. Or is there any easier way?
I saw that i can make use of hdparm call for getting some of the attributes.

I wanted to get the data off the WD2500 (250MB) hard drive so slaved it to an older Dell machine running Win 2k. Unfortunately, the older machine's BIOS is so old it can't read the larger hard drive. Then, I connected it to a Gateway machine running Win 2k; it started running chkdsk on the WD2500 drive and indicated it was 'fixing' a bunch of errors. It appeared to be in an endless loop, fixing the same problem over and over, so I killed the power. Then, I booted the Gateway machine with Knoppix Live CDIt shows the 250G hard drive in the file manager window. When I click on the 250G hard drive icon it shows at the bottom of the window '1 visible item (0 hidden), Free space: 97.4 GB (Total: 250.0 GB)This seems about rightHowever, the file listing only includes a single item, 'Documents and Settings' of size 4.1 kb. So something to do with the directory structure is corrupted, but I don't know what, and I don't know how to fix it

I 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.
