Buffer I/o Error On Device Dm-0
question Anybody can answer The best answers are voted up and rise to the top Is this drive failure or something else? up vote 10 down vote favorite 2 I have a year-old drive that's giving me trouble. 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 kernel: buffer i/o error on device looks like this is a symptom of a failing drive. How do I confirm this, 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_

I cannot use smartmontools because the disks are handled by a 3ware card which has it's own (very limited tw_cli utility).

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, http://www.ubuntu-es.org/node/183155 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 http://kb.fortinet.com/kb/documentLink.do?externalID=FD37499 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 error on 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 error on device 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!

En el caso de una partición del disco rígido se refiere a un error de hardware, en la controladora de disco o el disco propiamente que tiene sectores defectuosos. En esta caso corresponde a la partición de Windows /dev/sda1. Para comprobarlo,
