Hardware :: "Failed To Read Block" During Fsck
May 30, 2010
I woke up this morning to the horror that the ext3 partition on my 1TB drive (the only partition on this drive), in an external USB drive case, was not readable. I did some poking around on Google for related issues, and found that what worked for many was to have fsck check, and possibly fix, some errors that have occurred on the partition. This I did with the following command:
Code:
root@naglfar:/# fsck -y -C -V /dev/sdc1
fsck 1.41.4 (27-Jan-2009)
[/sbin/fsck.ext3 (1) -- /dev/sdc1] fsck.ext3 -y -C0 /dev/sdc1
e2fsck 1.41.4 (27-Jan-2009)

About a month and a half ago I purchased two new 500GB serial ATA hard drives from Best Buy to replace my other, very old 186GB SATA hard drive. Since then I've had issues with Linux. Sometimes when it's booting it gives a bunch of error messages, such as "failed to set xfermode," and then it boots. Other times, after INIT has started, I get ext3 errors about failing to read an inode block, then "cannot start /sbin/agetty" and "ID c5 respawning too fast," and at this point booting fails altogether. These errors seem to happen randomly. However, once the system has booted, everything seems to work fine, and there are no further issues.
I know it's not a faulty hard drive or filesystem because I've tried Linux on both hard drives numerous times, and I've reformatted many times, one time I even tried erasing one of the hard drives byte for byte and then formatting it, and still had issues.
I've tried Arch Linux, Gentoo, VectorLinux, and openSUSE, and all of them have given me these problems. The live CD's for Ubuntu 10.04, Clonezilla, and GParted all have trouble partitioning/cloning/installing to these hard drives. At this point, it's obvious to me that there is a universal problem with this particular model.
GRUB and Syslinux both work fine, and Windows XP works fine too. It's only Linux that's giving me issues.
I would rather not buy a new hard drive if I can help it, seeing as these two are almost brand new. Is there some BIOS setting that could be causing these problems? Is it some unsupported feature in the hard drives? Is it a bug in the Linux kernel?
The hard drive model is WD5000AADS. Both hard drives are this same model. My motherboard is an NForce 680i SLI.
EDIT: I've tried ext2/3, ReiserFS, and XFS, and all of them do this, so I don't think it's a filesystem issue.

Booting up fails with code 126. I am greeted with the following error everyime I start up.
Checking root file system.../etc/rcS.d/S10checkroot.sh: line 174: /sbin/logsave: Permission denied
failed (code 126).
It then says an automatic fsck failed and a manual fsck must be performed, then the system restarted. I have done a manual fsck and it did nothing. I booted up the system with knoppix and did it, nothing.

I have Debian Wheezy on my Dell Vostro 1710.
There is a fsck scan happening every 35 mounts on my laptop (i.e. when I boot)
It was fine until a few weeks ago when it started to fail.
Here is the error message :
What should I do to fix that ? I use my laptop to go on the Internet and I don't remember modifying/installing anything that could make this happen.
I found the answer : [URL] ....
I just had to type the root password and run fsck manually as follows : fsck /dev/sda7.

my cmos battery is dead , not worrying that much about it but the problem is ubuntu , it has trouble booting thanks to fsck , there is a bug herebut i cant boot , i get the following error # Superblock last mount time is in the futureand i cant boot , i can get it working sometimes , with allot of work , but normaly it just fails !i came to the conclusion that the CMOS time and date keeps reseting and so ubuntu thinks that the last time i booted was in the future (if this makes any sense) and fsck freaks

We have a server for which the root password had been lost, and there were no other user accounts set up. Yesterday evening I attempted to reset the root password by booting from the install CD and using VI to clear the root password in the passwd and shadow files. I then rebooted, and the system has halted with an 'FSCK failed. Please repair manually and reboot' error, with a prompt to 'Enter root password' below. But of course the root password isn't known (I had expected it to blank after editing the passwd and shadow files, but it doesn't work), so I have no way of logging on.

I have Ubuntu 9.10 installed on my HP desktop, but I'm running an older version (8.10) on a live CD so I can at least get online to ask for some When I tried to log on earlier it went to a command prompt and said the 'file system check failed' and to run fsck manually. I entered 'sudo fsck' at the prompt and I selected "y" to fix all the bad inodes, when it was complete it told me to restart, I then entered 'sudo restart' at the prompt and it said 'sudo uuid unknown'. I have not installed anything recently and I'm not sure what to do.

When I do a forced fsck, I would like to have a log file to look at after boot.
When I check /var/log/ there are no files there with fsck output
I've run force fsck in these ways:
shutdown -rF now
-and-
touch /forcefsck

My F12 installation, which was installed on an HP tx2500z laptop and has been operating relatively well since January, now fails to boot after a frozen screen precipitated a forced shutdown. On reboot, I was dropped into a shell with the error message "Error reading block 1546 (Attempt to read block from file system resulted in a short read) while getting next inode from scan." recommending to run fsck manually. During the fsck run, after a substantial number of Pass 1 inode count corrections, the "Error reading block" message reappeared, with the question "Ignore error<y>" to which I answered "y".
fsck responded with "Force rewrite<y>". Since I did not know what would be written here, I said "no". I then forced shutdown, rebooted into Windows, and searched for further guidance. One suggestion was to run fsck -y on the affected partition. My laptop drive has four partitions, the first two being allocated to Windows and an HP supplied repair partition. sda3 is a tiny boot partition (100 MB), and sda4/5 is the LVM remainder.
fsck -y /dev/sda3 told me the boot partition was fine.
fsck -y /dev/sda4 stopped immediately and asked "Could this be a zero-length file partition?". Given the ext3 structure, I suppose the correct answer is yes.
fsck -y /dev/sda5 told me fsck.LVM2_Member: not found.
Following this, I then attempted again to reboot, and ran fsck without options. Once again, during Pass 1, Block 1546 exhibited the short read error, again asking about a rewrite - which I once again answered no. Pass 1 completed with another substantial number of inode count corrections, and Pass 2 started - immediately generating the message:
'passwd' in /etc/pam.d (65556) has deleted/unused node 7831. Clear<y>
After some hesitancy, I said "yes", and of course a second similar message appeared. I was brave enough to answer "yes" six more times, with the first two referring to /etc/pam.d inodes, and the next four referring to /etc/security/console.apps inodes. The eighth message, also similar, referred to inodes elsewhere - but by now I did not dare to continue and forced shutdown. Is this repairable, and if so, how?

I am using Wind River Linux- 2.6.27.18-WR3.0bg_standard. The problem is whenever I execute "reboot, ls, cd" and many other commands the OS prompts me an error-
"end request: i/o error, dev sda, sector "(different sector each time)" and
EXT3-fs error (device sda1):ext3_get_inode_loc:unable to read inode block- inode-4088001, block-4097027
I also executed "dmesg", it also showed similar errors. Has the disk gone bad or the kernel is corrupted?

algorithm:breada
input: file system block number for immediate read
file system block number for asynchronous read
output:buffer containing data for immediate read {
if(first block not in cache) {
get buffer for first block
if(buffer data not valid)
initiate disk read }
if(second block not in cache) {
get buffer for second block)
if(buffer data valid) //line 1
release buffer else
initiate disk read //line 2 }
if(first block was originally in cache) //line 3 {
read first block
return buffer }
sleep (event first buffer contains valid data)
return buffer }
Here is an algorithm for block read algorithm. I have problem in
line 1: If buffer data is valid why is it releasing the buffer?
line 2: If buffer data valid why is it initiating disk read. It should have read directly from buffer?
line 3: It should be the first condition as if it is there in cache then it should return it without delay?

I'm trying to install Kubuntu on an old Windows system. I am getting tons of errors such as:
I/O error
SQUASHFS error:unable to read page, block XXXXXX
SQUASHFS error: unable to read fragment cache block
It then reports that it's loading ACPI modules and starting the ACPI services, starting the system log daemon, doing Wacom setup, starting kernel log daemon.....and then it reads sb_bread failed reading block umptysquat.I have a feeling that this hard drive is toast. I can't get it to install Windoze or Linux. I can't even get a prompt so I can do a low-level format. Unfortunately, I'm not super savvy with Linux and don't know what to do next.

I have debian testing installed on my system. I have a separate home partition which i shared with Pardus2009 which i installed later on a different partition.
Now pardus boots fine without errors, but debian says "filesystem check failed" because last mount time of / is in future. it gives a maintenance shell and after a manual fsck corrects this problem, debian reboots fine, but then says theres a problem with the /home partition (but this can be ignored)

I have bunch of partitions on my Debian server installation, so I was experimenting with partitions and saw that is one partition fails fsck on booting time, system waits for root password or CTRL+D key combination. The problem is that my Debian machine is headless and I use only SSH to it. So if fsck fails, I can't to login to SSH (off course, because it is not loaded at this time). So I need to go with monitor and keyboard to machine and press CTRL+D.One option is to disable disk checking at startup by changing fstab file. I don't like this option. Is there any possibility to auto continue booting Debian machine ?
