Linux Cp I O Error
Contents |
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 cp closing input/output error have an I/O error. I/O error means that the storage media (card, disk, …) cannot be read input/output error linux 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.
Cp Cannot Stat Input/output Error
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 cp failed to extend file too large 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 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? June 6th, 201

I am trying to save most files as possible. I am trying to create a backup of my home directory on an external drive using tar -cvf backup /home/myHome and also have tried rsync -vfh /home/myHome /media/backup Both methods stop when they found a corrupt file. Is there a way to force http://unix.stackexchange.com/questions/29728/force-copying-a-corrupted-home-directory one or the other to continue copying and ignore bad files, copying everything that is possible to copy and show me a log at the end of the files that were not copied? Thanks. backup rsync tar home share|improve this question asked Jan 22 '12 at 19:55 SpaceDog 1,21172342 I have not enough time for full answer, but my approach would be mounting read-only the partition containing /home and then keeping a copy of the partition's image in a file with dd conv=noerror if=/dev/sdXY of=/media/backup/sdXY.dump. Then you can fsck the image file and mount it with -o loop. –forcefsck Jan 22 '12 at 20:54 add a comment| 5 Answers 5 active oldest votes up vote 3 down vote accepted I wrote a little script for that #!/bin/bash echo "copying from $1" find $1 -type f -print0 | while read -d $'\0' -r file ; do echo Processing "$file" target="$2""$file" if (test -f "$target") then echo File Exists: "$target" else echo copying to "$target" targetDir=`dirname "$target"` if (!

I only want the rest of the 85% complete files, and get a list of damanged files. How to do that? linux cp i cp stops on the first read error. scp/rsync complains and deletes the copy (wanted) and quit (unwanted). There is no way to continue after an I/O error, at least not found by reading rsync(1) manual. I Googled for a long while, all posts are about other needs: telling the poster that the IO error means hard disk is damanged (I know it); telling the poster a way to copy the good sections of a single file, fill damaged data with zeros (I have 100k files each less than 10KB, and damanged files are no use to me, even if only one byte is missing); telling the poster how to repeattedly run rsync (over network) to fight bad connection and finish the copy. telling the poster how to change default timeout to let rsync try harder to read the files (I don't wish to do this) telling the poster to run fsck to fix the file system error. Thanks for reading the list of unwanted answers! Note: This is a disk with physical damage, confirmed by the proper diagnostic tools. I've also run a thorough fsck. linux hard-drive command-line rsync file-transfer share|improve this question edited Nov 21 '13 at 7:22 asked Nov 21 '13 at 7:17 Zhang
