Cp I O Error

a crash of the video application. How to Detect an I/O Error It's easy to verify whether a file has I/O problems: Just try to copy it to a different location. If the operating system reports an error (Finder error -36 for Mac) then we have an I/O cpio error file error. I/O error means that the storage media (card, disk, …) cannot be read at a certain

location. Think of 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 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. 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 cpio 0511 025 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 really worth the wait, because now we have a clean file on which we can use our arsenal of diagnostics, preview and video recovery tools. I/O errors are a serious business, and scrapping the card after recovering the videos is probably the RIGHT THING TO DO. You should also consider that some amount of footage won't be recovered, or with a less-than-stellar quality. But that's a whole lot more than what you have now, right?

I am trying to copy all the recoverable contents onto a spare HD, but every method I try fails when an error is encountered - leaving the remaining files uncopied. Finder - Fails. SuperDuper - Fails. Ditto (terminal command) - Fails. I was hoping that Ditto would do the trick, the Ditto man page says: ditto returns 0 if everything is copied, otherwise non-zero. ditto almost never cp i o gives up, preferring to report errors along the way. Diagnostic messages will be printed to standard error. I have submitted a bug to Apple re ditto failing to perform as advertised.

However crafting the right command line arguments may be somewhat complicated. A nice rsync GUI is Carbon Copy Cloner (donationware) After you are satisfied with the cloning setting, launch clone in CCC and immediately after run from terminal ps axuww| grep rsync and you will see the right command line arguments. Then just add --ignore-errors share|improve this answer answered Feb 7 '12 at 15:34 sumx 53222 rsync is very nice since when you ask it to recursively copy entire directory trees, it will log errors and move on. You can then kill the sync - look over the errors and then exclude some of the worst offenders if the depth-first search jumps to a really corrupt directory before reaching files you need to copy. –bmike♦ Feb 7 '12 at 15:52 9 --ignore-errors does not what you think it does. It tells --delete to go ahead and delete files even when there are IO errors. –LCC Aug 21 '13 at 9:2

But I have experienced "Input/output error": $ rm pic -R rm: cannot remove `pic/60.jpg': Input/output error rm: cannot remove `pic/006.jpg': Input/output error rm: cannot remove `pic/008.jpg': Input/output error rm: cannot remove `pic/011.jpg': Input/output error $ ls -la pic ls: cannot access pic/60.jpg: Input/output error -????????? ? ? ? ? ? 006.jpg -????????? ? ? ? ? ? 006.jpg -????????? ? ? ? ? ? 011.jpg I was wondering what the problem is? How can I recover or remove the directory pic and all of its content? My OS is Ubuntu 12.04, and the removable hard drive has ntfs filesystem. Other directories not containing or inside pic on the removable hard drive are working fine.
