Buffer I/o Error On Device Sda Logical Block 0
an sd card with a new image on it it booted up straight away. The pi seems to be working fine as far as I can tell.I have since tried the 32gb card in my phone, pc, etc and it is recognised as buffer io error on device logical block being there but shows no other signs of life - will not be formatted by phone, not assigned a drive letter by computer. Is there anyway to get this back to life or is it completely dead?And my other question is - is there a way to avoid this happening again? Should I disable swap on the pi? Any other tips?Thanks in advance Support The MagPi by purchasing printed copies from one of our retailers - http://themagpi.com/en/buyPlease share with anyone who is interested!

If you can't get a drive letter not sure what you can do.All I can think of is there is a protected area on SD Cards yours probably got written to.Either that or you need an updated driver on your computerCheck this site for infohttps://www.sdcard.org/downloads/formatter_3/ http://www.raspians.com - always looking for content feel free to ask to have it posted.

I have a problem when trying mounting, checking my ext3 partition. Is a external HD with my "portable" Linux system. Suddenly started to fail, when I try to boot it, the GRUB can't locate the config file, and show me the command line. I boot from my internal HD and try to mount it and have this messages. Code: sd 2:0:0:0: [sdb]
required. The only problem was the host computer kept throwing errors when trying to access the video file. I was asked to dig into https://developer.ridgerun.com/wiki/index.php/Storage_device_USB_or_SD_Card_debugging the details. Do no harm The first thing I did was copy the http://askubuntu.com/questions/686810/is-it-possible-to-repair-sd-card raw contents of the entire SD card to a file. That way I can make mistakes on the image file without risking loosing the video file on the SD card. You need to be careful as most host computers will try to mount the file systems on the SD error on card. I have my Ubuntu box configured so auto-mount is disabled. To find the SD card device file I used dmesg. [3097298.239288] sd 154:0:0:0: [sdi] 15523840 512-byte logical blocks: (7.94 GB/7.40 GiB) As you can see, in my case the device file was /dev/sdi. You may also see devices files like /dev/sdi1 and/dev/sdi2 (try cat /proc/partitions). These device files expose the partition contents. error on device We want to copy the entire SD card, so I used /dev/sdi. Your computer will use a different device filename. My first attempt was to use 'dd to do a raw copy of the entire SD card contents: sudo dd bs=64M if=/dev/sdi of=sd.img I saw errors and the copy stopped before all 8 GB were copied. dd: reading `/dev/sdi': Input/output error 47+1 records in 47+1 records out 3168010240 bytes (3.2 GB) copied, 531.645 s, 6.0 MB/s So, I tried again telling dd to ignore errors and fill the unreadable areas with zeros: sudo dd bs=64M if=/dev/sdi of=sd.img conv=noerror conv=sync with output dd: reading `/dev/sdi': Input/output error 117+2 records in 119+0 records out 7985954816 bytes (8.0 GB) copied, 868.579 s, 9.2 MB/s It is interesting the file size using dd is bigger than expected - 7985954816 bytes in the dd created copy where as the kernel reported the size as 7948206080 (15523840 512-byte logical blocks). I suspect this has to do with the last block being increased to match the 64M boundary of my block size setting. I then used dmesg again to see what typ

I just want to format my micro-SD card so I can write a Raspbian image to it for my RPI. To begin with I am pretty new at Ubuntu so I am pretty sure that I probably did something that "destroyed" my micro-SD. These are the commands I used: sudo -i umount /dev/mmcblk0p1 dd bs=4M if=2015-09-24-raspbian-jessie.img of=/dev/mmcblk0 After 24+ hours I got impatient and just closed the terminal (I know now that this was probably not the smartest thing to do... and this is probably what destroyed my SD-card) I tried using disks but it gives me an I/O error... I tried using gparted but right after creating the FAT32 system, gparted just keeps searching and nothing happens... I tried using testdisk but with no luck... I have tried using fdisk but with no luck... I have not yet tried on a different OS and I do not know if that would even work Dmesg output: dmesg|tail: [ 87.292298] mmcblk0: error -110 transferring data, sector 2, nr 6, cmd response 0x900, card status 0x0 [ 87.292305] end_request: I/O error, dev mmcblk0, sector 2 [ 87.293240] mmcblk0: error -84 transferring data, sector 3, nr 5, cmd response 0x900, card status 0x0 [ 87.293245] end_request: I/O error, dev mmcblk0, sector 3 [ 87.294110] mmcblk0: error -84 transferring data, sector 4, nr 4, cmd response 0x900, card status 0x0 [ 87.294115] end_request: I/O error, dev mmcblk0, sector 4 [ 87.296545] Buffer I/O error on device mmcblk0, logical block 0 [ 87.297431] ldm_validate_partition_table(
