I recently got a bad virus that wouldnt let me reinstall Windows so I figured I would install Ubuntu and give it a go, but now it says my hard drive has "many bad sectors" a quick Google search shows many ways to fix this in Windows, but how do I do it in Ubuntu?Easily since Im just getting the hang of things.
View 8 RepliesMy sister's laptop (toshiba satellite l550 running lucid) often runs really, really slow, even after a fresh install. Going through the gnome main menu, everything just lags by several seconds. Closing applications often takes a while, etc. I've run top and iostat to determine what the problem is and it seems to be IO-related. User processes and system processes don't take up more than a few percent, but the average load is usually over 2 even when I'm barely doing anything. Top shows that, whenever everything slows down, the 'wait' criterion is pretty high.
Now, I've also tried installing lucid to an external USB hard drive and that works fine. I'm currently running the S.M.A.R.T. diagnostic and so far I've got the attached screenshot to show. Only the criterion shown and the 'current pending sector count' are showing warnings.Any thoughts? Could the performance issue be related to the hard drive warning? I'm not planning to replace the hard drive just yet, because this laptop still has a two-year warranty.
How would one determine the capacity in sectors or LBAs of a USB Hard Drive? If I know the USB device number, like from 'lsusb', is there someplace on the system to get other information about the drive? What I want to do is have a program go out and get this information just for the number of LBAs on the drive itself. Partition info doesn't matter for what I am doing.
View 2 Replies View RelatedI recently tried Fedora on my laptop (previously Debian; I was bored one day) and gnome-disk-utility (palimpsest) warned me that my hard drive had numerous bad sectors. I re-installed Debian to find that this software was installed before so why had it not warned me?
When I load the disk utility, it says SMART is not available. I've got smartmontools installed, I can run a self-test with smartctl but I don't think this shows bad sectors. I've tried starting smartd on startup but the disk utility never changes from "SMART is not available". It is possible for it to work with this hardware as it works in Fedora on this laptop; any ideas?
I'm kind of new to programming in Linux & c/c++. I'm currently writing a FileManager using Ubuntu Linux(10.10) for Learning Purposes. I've got started on this project by creating a loopback device to be used as my virtual hard disk. After creating the loop back hard disk and mounting it has the following configuration.
Code: $> sudo fdisk -l /dev/loop0
Disk /dev/loop0: 10 MB, 10977280 bytes
255 heads, 63 sectors/track, 1 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/loop0 doesn't contain a valid partition table Now what I want to do is develop a c++ program to read & write files to this loop back device,which I'm using to simulate an actual hard disk,at the blocks & sectors level. So far I've come up with the following code. But I'm still unable to read files from the hard disk one block at a time.
Code: #include <iostream>
#include <stdio.h>
using namespace std;
int main() {
char block[512]; int length=0;
cout<<"Implementation of the File Handler Read Method..."<<endl;
FILE *f = fopen("/dev/loop0", "r");
if(f == NULL) {
cout<<"Error In Opening the HardDisk File Retuning Error..."<<endl; return -1; }
//Read One Block of Data to Buffer length = fread(block, 1, sizeof(block), f);
/* Do something with the data */ cout<<"Length : "<<length<<endl;
return 0; }
When I run this Program All what I get is the message for NULL. "Error In Opening the HardDisk File Retuning Error...". So I could open the loopback device as a file an access it at the sectors & block level.

View 8 Replies View RelatedI have 2 WD20EARS hard drives on the way (2 TB green WD disks with 4k sectors) and I'll be installing Centos 5.5 in RAID1 on them (2 partitions, one 16 GB / at the beginning and the rest in its own partition). I read the following thread: [URL]
and it seems that I might be having problems with the 4k sectors (Advanced Drive Format in WD lingo). I'm confused as to what exactly to do. I was thinking of downloading Fedora 14 Live CD and partitioning there and then switching to Centos 5.5 to install. Will that work? Seems I want the md 0.9 metadata because it doesn't have the space limit for me (2 TB) and it's stored at the end of the partition so it avoids alignment issues. Will I be able to make that happen with Fedora 14?

View 2 Replies View RelatedMy 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.
Trying to install Fedora 12 using the 6 CDs. Trying to install on an older x86 box.Problem is that when detecting my hard drive, Fedora 12 recognizes it as a sda hard drive instead of hda hard drive. I have no SCSI connected to my computer what so ever. It's an old fashion PATA Western Digital hard drive.If I proceed with the install, Fedora 12 only installs 200MB of the OS from the first CD only. No options for additional software or anything.

View 2 Replies View RelatedI have a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.

View 3 Replies View RelatedI just booted one of my computers from a usb drive I had installed Ubuntu 10.04 LTS to, and when I booted it up on that computer, it worked fine. Then, when I powered down the computer and booted it back up to the main hard drive, it booted to the same that my flash drive was running, but my flash drive was not plugged in!! How is this possible? Did it copy itself over my other operating system? There is no trace of it. By the way, that, too, was ubuntu 10.04.
View 2 Replies View RelatedI would like to install Linux Ubuntu 11.04 on an external hard drive - its partitioned and ready for Linux.I've downloaded and burnt the .iso file to a DVD so its all good so far...First of all... is this possible without messing up my macbook? I don't particularly want to break into my macbook to disconnect the hard drive (I read on a tutorial for a previous version of Ubuntu that I'd have to do that... - does it still apply to 11.04?) - as it voids the warranty (I checked ).The reason I ask this is because I had a friend who partitioned their internal hard drive and installed Ubuntu on it. But after installation was complete they couldn't boot up Windows 7 or Ubuntu... and it resulted in them having to clean install Windows 7... - I don't want to end up in that situation
Second... If it is possible to install it without messing up my macbook... - Do I just follow the install instructions but just make sure that where possible I make sure that everything is installed on my external hard drive?...I really need someone to put my mind at rest that everything will run smoothly and that I'll be able to run Mac OS X as usual but also that I'll be able to boot from my external hard drive to run Ubuntu.
I am trying to move a whole bunch of files from one partition on one hard drive to the same partition on another hard drive.

Shutdown the server, take out /dev/hda1 and boot up with the new drive and it's /data contents.

View 9 Replies View RelatedI am soon going to have to return my intel ssd for replacement. Therefore, I am going to be cloning the 160gb drive to a 320gb drive to keep my system settings while I am waiting for my new drive. I will not change the size of the partitions to fill the 320gb drive. I'll just change the grub settings if I absolutely have to. After that, I am going to have to clone the 320gb drive back to the replacement 160gb drive. Am I going to have problems doing that since I will be going from a larger to a smaller drive?I typically use Clonezilla with the default settings.
