General :: External Hard Drive Is No Longer Recognized - Buffer I/O Error On Device Sdb1, Logical Block 6160408
Feb 28, 2010
The external hard drive which contains all my photos and where I backed-up all my important documents is no longer recognized. It is a three month old 500GB Iomage Prestige Desktop Hard Drive.When I plug it in, it is recognised as a USB device, because it shows up when I type lsusb, but dmesg gives this error message.
[19712.013250] usb 2-2: new high speed USB device using ehci_hcd and address 21
[19712.145347] usb 2-2: configuration #1 chosen from 1 choice
[19712.147214] scsi25 : SCSI emulation for USB Mass Storage devices
[code]....
I popped the disk out of the casing put it on a SATA connect internally and then tried the file recovery programs testdisk/photorec and SpinRite, but both failed because they couldn't recognize the external hard disk.
I am trying to debug the issue of a desktop that has for the last two weeks started having kernel panics at boot time. This machine has been running flawlessly for the last 8 years, and has had three OS upgrades. I am using memtest to try to understand the issue. The following is part of the memtest output: Reading all physical volumes Buffer I/O error device hdc logical block 0 Buffer I/O error device hdc logical block 15
Illegal node for this track or incompatible media (asc=0x64 ascq=0x00) The failed "Read 10" packet command was /dev/hdc: read failed after 0 of 4096 at 0 Input/output error and similar set of mesaages After this udev checks correctly, and hardware, storage and audio are initialized However sometime in the middle of the boot process, a kernel panic occurs with message Kernel panic -- not symcing : Fatal exception in interrupt
I have 2 hdds, with encrypted / and /home. Besides there are four other (encrypted ext4) partitions I use rarely. In Fedora 11 at boottime I gave the luks passphrase for / and home and the system booted as intended.
Whenever I needed those extra encrypted partitions I mounted them in Nautilus. Now, in Fedora 12 at boottime dracut tries to open all the encrypted partitions, / and /home are mounted fine, but opening all the other partitions gave the following messages in messages.log:
Quote:

...and these messages are repeated with the other partiitions, and the boot time takes very, very long. How can I tell dracut to ignore those extra encrypted partitions at boottime?
i have a inspiron 1520 laptop which is starting to slow down some so i thought linux would help because all i do is internet use, so i download it from another computer and mount it to a usb flash drive like the site says, (netbook remix latest version) then i put it in my laptop and it loads all the way and i press try and after about 10 minutes of loading it lets me try. so that was ok really slow but i thought id install it to hard drive to see if it improved speed. so the next time i start my laptop i get Buffer i/o error on device loop0 logical block xxxxxx so i redo the usbflashdrive no errors switch usb ports and same thing, ive done the switch usb ports and redo the flash drive about 4 times im really getting mad at linux before i even have it installed.
I just downloaded an iso of the latest CentOS dist (5.3) and burned it to disk. I booted from the CD and received the following error: Memory for crash kernel (0x0 to 0x0) not within permissible range Illegal mode for this track or incompatible medium -- (asc=0x64, ascq-0x00) The failed "read 10" packet command was: Buffer I/O error on device hdd, logical block 176935
(This error message repeats for another 9 or 10 times then it says the following) Red Hat nash version 5.1.19.6 starting Setting up new root fs (Then there are some unmounts which are old /dev, /proc, /sys. At this point a series of steps begin).
Setting Clock Starting udev Loading default keymap (us) Setting hostname local host.localdomain Setting up logical volume management Checking file systems
These are just some of the steps that appear after the above error is displayed, all of the steps that load have an ok status. After those are completed I get to a text prompt - localhost login: At this point my keyboard does not seem to respond, pressing enter or any of the other keys seems to have no effect. I noticed that during the load process I could toggle the light for caps and num lock, but at the login screen it does'nt work. So at this point I'm not sure if I'm having a technical issue or if its just another case of an user error.
Create symlink /dev/root and then exit this to continue the boot sequence.

loops that during install. new hard drive fresh out of box. WD 320GB 7200 Toshiba Qosmio intell core duo i've installed with this same disk before previous hard drive died. installed over windows vista. this time im trying to install solo no windows disk to reinstall with, F10 only. I've tried other distros as well, Mandriva one 2009, Dreamlinux, and this one. i've suspected hard drive controller went out but i can format and partition the drive. also the cd/dvd drive is bad but im booting from cd fine. tried removing the cd drive and booting from an external usb cd rom, same errors.
im about to deploy and need my computer up and running ASAP. 7 months no entertainment is not good. when i use a linux boot disk from Ultimate Boot Disk (UBD) i get an error of - hda status no response and something about invalid heads dreamlinux pushes past the error till i get the error about cant start x server. about my graphics
i've just burned a livecd (fedora 11), but it doesn't work correctly.it says after i hit boot:
BUFFER I/O error on device sr0 logical block 352328
and then something else, which is similar so i didn't write it down.i read on bugzilla, that is should try to append the boot command with pci=nomsi, but it doesn't work for me
I have an external usb disk connected to a Debian desktop. A couple of days ago these messages started appearing in dmesg

When this appears the disk becomes unavailable and I have to remove and plug it in and mount again. After that it works couple of hour and then the problem appears again. Is this a hardware problem?
I compiled a new kernel for slackware 13 yesterday and all is going well, except for the fact that during boot I get errors regarding a second hard drive. They are of the form PHP Code:
[code]....
I wasn't getting this error with the previous 2.6.29.6 kernel. As far as I can tell everything is working fine, but the errors make me nervous as this is where all my data is stored. The partition was previously formatted ntfs-3g and I thought maybe I'd done something with ntfs support while configuring the kernel so I backed up the data, reformatted to ext4 which matches all other linux partitions except for swap of course, and I get the exact same errors.
1. Is there something different in this kernel in reporting errors or maybe something I set in configuration?
2. recommend a good (simple and ubiquitous) cli program to check the disk for errors so that I can run it in both the old and new slack kernels as well as mandriva on the same machine?
I have an external hard drive that connects through an expansion card with eSATA on it. It was partitioned and formatted as NTFS in Windows but isn't recognized in Ubuntu 10.04.
I have a Linux application(ProMAX 5000) running in a virtual Machine on my windows OS. I am using an external Hard drive of 250G in ext2 file system as my device for large data read, write & execute file system. I have already mounted the device from /etc/fstab. But i want my application to access this device as a Primary data storage device OR Secondary storage device. What command will i invoke to partition this 250G drive as my primary or secondary storage device.
I have a problem with my external hard drive. I've always used to connect it to my Ubuntu Server with the following command: sudo mount -t ntfs-3g /dev/sdc1 ..and it's worked fine, but after a reboot I did a couple of times ago, the hard drive no longer appears.sudo fdisk -l doesn't show the hard drive anymore. Connecting it to a Windows computer works, I even tried the "safely remove harddrive" function, but to no avail.
I'm very new to Ubuntu. Now that I have it installed, my computer doesn't recognize my external hard drive or flash drive. How do I access my external hard drive and flash drive? I'm also trying to get Rosetta Stone to work using Wine, but having a heck of a time. I've searched the forums and have found some similar topics, but nothing that really helped me.
I am setting up a Linux laptop for my parents, and want to also create some backup scripts to allow them to easily back up to an external hard drive. [And for them to be able to use it, it has to be super simple.]
For security purposes (should the external drive ever get lost or stolen), I want to encrypt the entire device using TrueCrypt. That means my scripts will have to use TrueCrypt to mount the backup volume using the device name. [Right?]
Now to the actual question(s): 1) Is there a way to ensure that an external hard drive will ALWAYS be assigned the same device name when plugged in? [That would be the simplest solution for me.]
2) Alternatively, is there a way (using bash scripting) to "find" the device name of a particular external hard drive, even if it might not be known in advance.
I have WD external hdd (80GB) formatted with fat32. I was using this hdd to transfer the data from computer A (LINUX, RH9) to computer B (Win7).
I was keep copying and deleting the data in the WD hdd during the data transfer because the amount to transfer is more than 300GB.
After doing this several times (and the WD drive was emptied), comp. A said the disk is full. I checked using 'df' and it was really full but 'ls -la' shows that there is no data in it.
I checked it in comp. B, and it showed empty. I tried to format in comp. A using 'mkdosfs -F 32 /dev/xxx# (block#)', but showed an error message like below.
'Warning: block count mismatch: found 78xxxxx but assuming 0'.
I found a similar situation in this forum metioning 'possible damaged linux kernel (not exactly same expression though)', so I re-installed linux in comp. A, but the problem was not solved.
1. why the disk info. is showed differently in linux and win7 2. why I cannot format it
I got a dell inspiron 1501 laptop with a 80Gb sata drive what is the best solution to add data storage space for someone that love to have multiples operating systems at hand Note: I use mostly linux so I won't need to change my laptop for many years maybe ...
For some reason, the second hard drive (sdb1) is not automatically mounted:

Before I installed Ubuntu, I installed the RAID software to handle 4 500 GB hard drives - so there are supposed to be two mirrored drives. I'm not an expert in using RAID. I'm assuming it is correctly configured. I only "see" two drives. sda has Ubuntu etc. How can I get sdb1 mounted? I've tried using the palimpsest program but I'm afraid I screw it up. Do I need to re-format sdb1?
I have an external hard disk drive and I would like it to be recognized with the same name (e.g. /dev/sbd) after each boot. Is there any way to make that?
I have one hard disk (call her HDA) that contains nothing but a single ext4 partition containing a backup of all my important data. Last night I did a clean install of Ubuntu 10.10 on my primary hard disk (call her HDB) and from there proceeded to upgrade directly to Ubuntu 11.04 upgrade. In 10.10, I was able to read HDA just fine. However after the upgrade, I can no longer mount this drive. When mounting from file browser:
Code:
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda,missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so The end of dmesg said the following:
Code:
dmesg | tail [ 82.130904] EXT4-fs (sda): bad geometry: block count 122096646 exceeds size of device (122096381 blocks)
my hard disk has a block count greater than the size of my device. I've done my background searching on this and tried a command line utility I've never heard of before:
Code:
# sudo e2fsck /dev/sda e2fsck 1.41.14 (22-Dec-2010) The filesystem size (according to the superblock) is 122096646 blocks The physical size of the device is 122096381 blocks

this is as far as I've gotten. This drive holds over a decade's worth of work for me and is extremely valuable. I really didn't think that the Ubuntu upgrade process would mess with this drive, seeing as the Ubuntu install was contained on an entirely different drive. What is it that I need to do to restore my drive to working status?
A few days back, I was moving a file from my home directory to a 1TB WD external hard drive (NTFS). In the middle of the process, the power went out so moving was interrupted. Now, the file I was trying to move is there on the external hard drive, but it can not be read, moved, renamed or removed. Besides, the destination folder on the external hard drive and all other files in it can be read, but they can't be removed or renamed.
i have a 2TB WD external HDD, works ok in windows, although sometimes tries to run on some random driver.when connected in linux i get the following error, however, my other 500GB WD HDD works flawlessly:Quote:An error occurred while accessing '2TB Backup', the system responded: org.freedesktopUDisks.Error. Failed: Error mounting: mount exited with exit code 12: Failed to read last sector (3907027119):
Just installed Slackware 13 this morning. It's been a long time since I last tried Linux, but Slack works (a lot easier than Slack 8 did back when I last used it!) quite well. I'm using the XFCE desktop and it's smooth as silk except for one odd problem-I cannot get any of my USB drives to mount. I just plugged in my Lexar 4GB USB flash drive and received an error message. Here's from /var/log/messages from when I initally plugged in the drive (I have a 500GB WD MyBook USB external drive that is always plugged in):
Any ideas or suggestions of what to look at? I'm not familiar with HAL in Linux although I've seen plenty of discussion about it and have an idea of what it's supposed to (or break! ).
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.
I have a one problem when i mapped a SAN to the linux box RHEL 5.3 i show the following messeage Buffer IO error on Device /dev/sdband unable to find it in fdisk -l
I have Ubuntu/Vista dual boot desktop with Single HDD (200GB) that i cloned to an external USB HDD (320GB) using clonezilla. My intention is to use the external HDD as a backup to up running in case my 3 year old desktop HDD fails. To make sure the clone is good to use if need, i connected external HDD to USB port and tried boot from it but got "Error 18". I tried to Google got some infoDid a fdisk -lu and got the following.
