So I was trying to move a large amount of files when I got this error:

<<screen grab>>

The problem (apart from having corrupted data) is that the files affected will NOT copy anywhere. So, since in my case I was trying to clear data off a hard drive, I would have no option but to delete the files. This is a shame since many of the files may still be use-able and probably only a few dropped bits of data are causing the problem.

The other issue is: surely this shouldn’t have happened in the first place… the files were copied from elsewhere previously and, at that time windows explorer didn’t give any errors…

Here’s the rub – Windows explorer doesn’t verify the data copied after it is written!!

So, if you’d like to know how to get around this issue, read on…

• Use Teracopy – Win explorer is shit for copying large amounts of data – NEVER use it for that purpose!
• Don’t bother with Data recovery tools, unless you specifically know the data was deleted
• Use JFileRecovery 0.94 (softpedia link is good) – It can heal some files, but most importantly, will still copy the data regardless of corruption, appending “_recovered” to the file.
• Make sure to make a note for future reference that the file is possibly damaged [it rather depends what it is and whether the data is critical – e.g. audio and video files will probably still play fine].
• <<give a brief run-down of how to use>>
• In JFileRecovery, you can play with the Block Size and timeout if you want a more “thorough” recovery. Personally, I decreased the block size to 14,848 and increased the timeout to 2000ms to give a balance between the time it takes to recover and its likelihood of recovering data.
