Copying data to it fails after about 8-10GB of transfers. It spontaneously changes to 'read only'. It's properly formatted ext4, I'm the owner. Searching online, it looks like this is a symptom of a failing drive. How do I confirm this, buffer i/o error on device sda logical block 0 since the SMART tests indicate otherwise? I did the obvious like check the Disk Utility, and ran the extended SMART test. All results from Disk Utility come back perfect. Read error rate and reallocated sectors are showing zero. I'm guessing this disk is bad and SMART isn't detecting it, though I don't understand why. I'd like to confirm what the problem is. I'm having no problems with the other disks in the machine. fstab: proc /proc proc nodev,noexec,nosuid 0 0 UUID=62e11126-3f06-43f0-bd5a-29b411bb8160 / ext4 errors=remount-ro 0 1 UUID=5e2d6348-be6e-4d5d-8f7f-1a5c1cab7db2 /home ext4 defaults 0 2 UUID=97e594a3-c783-4c73-97c0-682afcdc88b6 none swap sw 0 0 /dev/disk/by-label/Media /media/Media ntfs-3g defaults,user,locale=en_GB.utf8 0 0 Output of dmesg | less: (There are hundreds more 'Buffer I/O error' lines above) [22734.511487] Buffer I/O error on device sda1, logical block 302203 [22734.511489] Buffer I/O error on device sda1, logical block 302204 [22734.511490] Buffer I/O error on device sda1, logical block 302205 [22734.511492] Buffer I/O error on device sda1, logical block 302206 [22734.511494] Buffer I/O error on device sda1, logical block 302207 [22734.511496] EXT4-fs warning (device sda1): ext4_end_bio:251: I/O error writing to inode 9437465 (offset 4194304 size 524288 starting block 302215) [22734.511500] ata1: EH complete [22734.511616] EXT4-fs error (device sda1): ext4_journal_start_sb:327: Detected aborted journal [22734.511619] EXT4-fs (sda1): Remounting fi

Of late, the installation error on is failing with the error: "Buffer I/O error on device sda2, logical block 66326416" and series of such messages displayed on screen, causing the installation to fail. Found this failure is observed for a new set of seagate HDDs. On the same server with new Seagate HDD, RHEL5 is installed successfully (ruling out HDD hardware error). I tried to load all the drivers that are there in RHEL5, but that was failing too. Am looking for pointers to narrow down the issue. error on device Thanks in advance. Sri linux initrd share|improve this question asked Oct 1 '13 at 10:43 keersan 14 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote accepted Okay, i got it after much struggle. The issue is resolved by replacing the isci driver with megasr (my raid controller driver) in initrd (that is used while installation). When isci.ko driver detected my Seagate HDD, it was getting errors during installation. After replacing isci.ko with megasr driver, the installation went fine. share|improve this answer answered Oct 5 '13 at 6:01 keersan 14 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

generalBuenas! Recurro nuevamente al foro para ver si alguien me puede ayudar con el mini-problema que tengo. Resulta que hace poco probe una tarjeta de video que tenia tirada y pues no me gusto y volvi a la que tenia antes ( nvidia gt520, no es integrada) supuse que no pasaría nada y pues pasaron 2 dias y no paso nada raro por el cambio tan rapido de hardware. (Escribo esta parte porque quizá hice algo que hecho a perder el disco aunque no tengo la menor idea.) Al tercer dia tenia el computador con mi sesion con windows (Particion SDA1) y se fue a negro y no respondio. Reinicie a la mala y la bios se demoro mas de lo normal en reconocer los componentes, y windows no iniciaba. Me las arregle para iniciar windows y pasar chkdsk y listo, windows volvio a funcionar. Pero cuando inicio ubuntu 12.04 (tengo dual boot) que tengo en una particion del mismo disco, me indica esto antes de llegar a lightdm: Buffer I/O error on device sda1, logical block 797027 Esto es solo una linea pero son varias. La forma que consegui ver el error desde el escritorio fue escribir en consola " dmesg -> ~/Descargas/loc " El documente loc es bastante largo y no quise copiarlo entero. Por si sirve agrego la informacion de fdisk -l Disco /dev/sda: 160.0 GB, 160041885696 bytes 255 cabezas, 63 sectores/pista, 19457 cilindros, 312581808 sectores en total Unidades = sectores de 1 * 512 = 512 bytes Tamaño de sector (lógico / físico): 512 bytes / 512 bytes Tamaño E/S (mínimo/óptimo): 512 bytes / 512 bytes Identificador del disco: 0x7cc67cc6 Dispositivo Inicio Comienzo Fin Bloques Id Sistema /dev/sda1 * 63 61432559 30716248+ 7 HPFS/NTFS/exFAT /dev/sda2 61432621 283121663 110844521+ f W95 Ext'd (LBA) /dev/sda3 283121664 312580095 14729216 83 Linux /dev/sda5 61432623 281119684 109843531 7 HPFS/NTFS/exFAT /dev/sda6 281120768 283121663 1000448 82 Linux swap / Solaris Ambos SO'S me funcionan bien, pero si es problema del disco no quiero dejarlo pasar. SI alguien me pudiera ayudar se lo agradeceria. Soy un usuario que lee para intentar entender pero no dejo de ser novato en todo esto... Saludos!
