to extend 'file': Input/output error up vote 2 down vote favorite I'm a user of Oracle Virtualbox on Ubuntu. And I used to copy vdi files as a kind of backup. Previously I did this (copying vdi file and then copying it back) many times without any problem. But today I experienced this error VirtualBox VMs/win_7$ cp ../../Bkps/win_7.vdi . cp: error reading ‘../../Bkps/win_7.vdi’: Input/output error cp: failed to extend ‘./win_7.vdi’: Input/output error I googled for this a little but from the advices on similar problems I undersood nothing unfortunately. Could anyone suggest how to solve this, please? The output from the dmesg is, (and I understand nothing from it) [ 2347.982876] ata1.00: exception Emask 0x0 SAct 0x1900406f SErr 0x0 action 0x0 [ 2347.982887] ata1.00: irq_stat 0x40000008 [ 2347.982895] ata1.00: failed command: READ FPDMA QUEUED [ 2347.982908] ata1.00: cmd 60/08:70:d0:da:f4/00:00:2e:00:00/40 tag 14 ncq 4096 in [ 2347.982908] res 41/40:08:d0:da:f4/00:00:2e:00:00/00 Emask 0x409 (media error)

operating system reports an error (Finder error -36 for Mac) then we have an input output error android I/O error. I/O error means that the storage media (card, disk, …) cannot be read at a certain location. Think of error creating directory input output error it as a scratch on a DVD or a "bad sector" on a card or a disk. The bad news is that this "rough spot" is in the middle of your file. If the "rough http://askubuntu.com/questions/509695/cp-fails-to-copy-with-errors-cp-error-reading-file-input-output-error-and spot" is big (a big scratch on your DVD, hundreds or thousands of "bad sectors" on your disk), then the chances of recovery will be low. But in any case, the first step is to generate a clean, error-free copy of the damaged file. Since some segments of the file are not readable, the best that can be done is to skip them. We will explain later how to do this. http://aeroquartet.com/wordpress/2012/06/06/how-to-copy-a-file-with-io-errors/ With a clean copy of the file, parts of the original data are missing, but we no longer have I/O errors causing our diagnostics and repair tools to choke and crash. How to Copy a File with I/O Errors To salvage all readable data, we will use a fault-tolerant copy utility called dd. dd stands for "disk duplication". This is a command-line utility bundled with Mac OS X. A free version for Windows is also available for download. Be extremely careful, even if you are familiar with command line, because dd can cause unrecoverable damage to your data if you don't specify correctly input and output. You have been warned. The arguments of dd are straight-forward: if=path_of_file_with_IO_errors specifies input path of=path_of_clean_copy_to_create specifies output path conv=noerror,sync tells dd to be fault-tolerant Your output path should not be on the same disk as the damaged file. Actually, you shouldn't continue using the card or disk with I/O errors, because it's likely to cause more problems in the future. After recovery the data, you should scrap it or at most use it to store unimportant stuff. Using the Clean Copy Due to I/O errors, dd can take more time to create the clean copy than a normal copy would take. But it's reall

I tried this with a known-to-work Debian ISO image and it worked without problems. Incidentally, you don't really need the -r switch for your cp but that's not what's causing the problem. –Joseph R. Oct 24 '13 at 12:25 I agree that the most likely answer is corrupt media, but the next most likely, at least in my opinion, is a filesystem issue, especially considering the reference to loop mounts. Sometimes these things can happen post-kernel update if module links need remapping, and among the worst offenders are live union-type filesystems. Probably it's a bad iso, though. –mikeserv Mar 6 '14 at 4:52 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote IO Errors are almost always a sign of damaged media.

You could use the method in the first link to check for hard disk errors or use seatools to evaluate the hard drives health.
