I face "read error " while booting. sometimes it start normally. someone told me to check hard disk for errors. i used gsmartcontrol for this. but from its result i am unable to decide is this hard disk failure or just minor errors. can somebody tell me do i require to change my hd or it just something else to cause such error.
View 5 RepliesI have just started using Valgrind,which really is great. Most of the reported errors look kinda weird, though I can't really understand what's going on here, for example:

sMsg=0x6974320 "blablabla"...) at MyCls.cpp:270
270 cout<<endl<<"m_FilePtr="<<hex<<m_FilePtr<<dec<<endl;
Basically, Valgrind reported the "Invalid Read" error at line 270 of file MyCls.cpp, which is simply a cout of the m_FilePtr variable, which is a member variable of the MyCls class. It's a FILE* variable I use to write repeatedly on a text file. The address reported (0x47a5ee8) is 296 bytes after the "this" pointer (0x47a5dc0),as Valgrind correctly tells me but I honestly don't understand that. And of course, I need to read that variable, not only for the cout (indeed,the error is reported at every reading attempt). Besides, the application doesn't crash, but still I would like to understand if I really have to worry about this "error".

after installing Ubuntu on one WD 500 GB hard disk and after making mistake and pasting wrong code into Terminal:my OTHER WD 500 GB hard disk that was also in the system (I guess it was "hd1") - died.The problem must be, I guess, I typed wrong code: "hd1,1" instead of "hd0,0".)500 GB (NTFS) of data was on that other (non-Ubuntu) hard disk, and now I can not access it anymore. While booting, system gives "Hard Disk Error" warning and stops.One again: I installed Ubuntu od one hard disk and at the end of instalation I pasted wrong code for GRUB, giving address of another hard disk. Now that other hard disk has error and will not work

View 3 Replies View RelatedI have just freshly installed Karmic on hardware that was previously running Intrepid without any problems. I have not installed anything beyond a few bog-standard applications. I am now running into regular system lock-ups because the / partition is becoming read-only. Once this happens I am unable to start any application or to shut down, because there is no write access. If I happen to have a terminal open, then it is apparent that the disk has become read-only because I can not remove, create or modify any file. If I do not have a terminal open, then I can not open one. Obviously there is nothing written to any log.

View 9 Replies View RelatedI have 2 IDE drives, Windows XP is on the Master drive & Fedora 12 is on a partition the other drive. I purposely installed the Linux boot loader on the same drive as Fedora because want to use NTLDR as the primary boot loader. According to a guide I found [URL], I should be able to copy the Linux boot sector to a file & put that copy on the Windows drive & then modify boot.ini, so I am prompted to with an OS choice a startup.
The problem is the command the guide gives to copy the Linux boot sector (dd if=/dev/hdb1 of=bootsect.lnx size=512 count=1) has outdated syntax and does not work. What syntax would make this command work in Fedora 12? Another guide I found ([URL]-vista-already) suggested using: Grub4Dos & modifying boot.ini. This method almost worked until grub gave an error that there was no kernel loaded. What would I type into the grub prompt to load the kernel? How would I automate the loading of the kernel, so I don't have to specify the kernel each time?

View 4 Replies View RelatedI have multi-version Kernels on a Dual Boot WinXP / openSUSE 11,3 box. It's been a LONG time since I needed to boot to Win XP and now that I find that I can't get to it, I can not say for sure what I did to break it. Looking back, I suspect that the method I used for the recent removal of one of the Kernel versions may have been innappropiate. Rather than unchecking in versions/package groups I may have just removed the unwanted kernel in the package list. Not sure. I've tried dinking around with menu.lst and Yast Boot Loader to no success. I get errors depending on what I messed with. Didn't try to reinstall grub until I checked here for help with a fix.
Here's some info:
Code:
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.

View 3 Replies View RelatedI had a dual boot (windows 7 + debian), both of them installed in my internal hard disk, with the GRUB in it. I have recently installed a second linux distro (mint), but I put it in an external hard disk. Now the GRUB allows me to boot any of the three operating systems, but I need the external disk to do it. It seems that after the mint installation the GRUB is now working from the external disk (if the external disk is not connected, the machine does not boot.) �Is there a way to change the location of the GRUB, to the internal hard disk of my laptop?
View 2 Replies View RelatedMy system decided to crash on me, hard. It was humming along happily for about 2 months and now doesn't boot. If I boot from hard-disk, I get grub. Launching the first kernel choice hangs. I thought maybe the install was corrupt, so I booted from usb install disk. The usb hdd didn't boot; something about an error trying to access /dev/sda . Unplugging the internal disk and plugging in the usb install disk does result in the system booting. Plugging in the internal disk in a running system usb-booted system does not result in the system detecting the disk.
How do I know if the disk is physically broken? This seems unlikely since it does manage to launch grub consistently. Or is this still possible? How can I try to mount whatever is left? The usb install disk doesn't even list the /dev/sd*. Any pointers on how to reformat the drive if it's not being mounted?
I was using Terminal and browsing a directory in my home folder. My "home" directory is located on "/dev/sdb1". When in Terminal I typed "ls" in one of my directories and the output was garbage. The output didn't show the files in the directory. I think it said something like, "input/output error". Unfortunately, I didn't write the exact error down. Instead I rebooted.The hard disk with the problem is:

I have a qzd notebook with an rdc 1010 flash drive. I have downloaded the new 11.2 version of opensuse and it now recognises it, so thanks for that.Only trouble is I get an error message of:Failure occured during following action: Setting disk label of disk /dev/sda to msdos. System error code was: -1013A little history is required in orderI had windows xp installed to begin with (fool me ay!) and when I installed the adobe flash player 10, it always crashed my internet explorer, so i managed to find flash player 7, which I installed and it worked (kind of; it played videos, but stallingly; although this might be to do with the fact that i was also upgrading to IE 8 at the same time) but after a few seconds of it playing a video the computer reset and the message DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER appears. It seems that this flash player was some kind of virus and I worry that it may of damaged the flash drive, or is it that it's just messed up the MBR.
View 1 Replies View RelatedI have about 170 Gigabyte free at the last of my hard. I have windows 7 and suse linux installed on the machine. When I try to install ubunto. I start to create the partitions manually because I want to add it as a third operating system on my PC. Anyway I create the 4 partitions /boot - / - /var - /home. Automatically it choose to install the boot on sda not sda 9 as the /boot was sda9. I click install.
It gives me this message "The installer encountered an error copying files to the hard disk:
[Errno 5] Input/output error
This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment." I burn another cd and do the same ... the same problem.
I try to create the partitions at the end of the hard disk not the beginning although I am sure that there is no error in the hardware but the same message. Lastly I change the boot to be created in sda 9. The same problem, when I do everything. I download Linux mint another operating system and do the same points. The same error message appeared by the way the boot is being damaged after restarting and I have to fix it from suse linux cd.
My system has Windows XP Pro SP2 installed on /sda1 and originally a 10.04 on /sdb1-3, now upgraded to 11.04. The Ubuntu system works fine (teething troubles with nvidia drivers on upgrade but fixed now), and the Windows system shows up in the grub menu, but when it's selected, I just get `GRUB Hard Disk Error' and nothing else. Windows installed properly, and booted successfully until I installed Ubuntu in the first place. I can still access the files on that drive from within Ubuntu.
I've tried fixboot in the Win Recovery Console, which sounded like it did something, but didn't fix the problem. This problem isn't new to grub2, by the way - I just haven't needed Windows in a year.
I have a dual boot System with Ubuntu 10.04 Netbook Remix and Windows XP SP3 on an Asus eeePC 1000HE. I had some troubles with updating kernels etc. and I ended up with following problem:
After grub reinstall, I am able to boot Ubuntu, also I can mount the windows partition properly. Trying to boot into Windows, I get the error:
Code:
It's all on one hard drive which doesn't show any errors:
Code:
Partition table entries are not in disk order
Code:
Some partitions don't show a file system because they are luks-encrypted.
As I mentioned earlier, I am able to mount sda1. I think the problem is that the Partition Boot Sector is corrupted, even though I am not sure if the ntfs partition is damaged at all or if GRUB is the problem.
As I said I had problems with a kernel update and therefore had to reinstall GRUB. I think, but I am not sure, that I accidentally installed GRUB on sda1 (the windows partition) instead of on sda. After I installed GRUB on sda again, I was able to boot linux and fixed sda1 with testdisk. Before, sda1 showed as four partitions (sda1p1, ... , sda1p4). I was not able to mount sda1 till I fixed it with testdisk. testdisk says the Boot Sector of sda1 is OK, so does ntfsfix.
Finally, an extract from my /boot/grub/menu.lst:
Code: ...
The Windows XP entry is added by myself. I don't know much about grub, so there might be the error.
I tried to keep it as short as possible (this is only the end of the story), I hope I didn't forget anything important. Please ask if there is something not clear.
I am in Tanzania with this netbook, so it is not possible to boot Windows CD and fix the windows partition with it, also I don't have a very fast Internet connection.
Is there a way to fix this without a Windows CD? Maybe it is just a dumb mistake in the menu.lst?

I am a novice in Linux but due to my academic requirement I had to install Linux (Fedora 8). I have 2 hard disk's (80GB & 20GB), on the first HD which is 80GB I have Windows XP and the other one I partitioned and installed Linux. Now the first problem is that, whenever I start my PC I get a error which says "GRUB hard disk error", however when I restart the machine it's fine and gives me the boot options.
Secondly, the HD containing windows was affected by virus so I had to format & reinstall XP. Strangely after that I am not getting any boot options and it's like windows is the only 1 OS running. But on windows the partition on which Linux is installed in intact. So I assume something is deleted maybe the Linux boot file.
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.
