"Error code 36" while importing video folders from external HD

Was trying to import some video folders from my External HD and as usual it said it would take a couple minutes when out of nowhere the error showed up. There are times when it only imports a few clips then it like stop and brings up the error. Is there a solution to this?

Data corruption or disk error is what I suspect.


Use Disk Utility to run First Aid on the external drive device and the volumes it contains. This may correct any directory and/or structure errors that might exist. In Disk Utility be sure to click View > Show All Devices so that you can visualize and select not only drive volumes but the drive devices themselves.


Likewise, it probably isn't a bad idea to run First Aid on your internal startup drive as well.

error -36 is I/O Error.


That sounds very generic, but us actually quite specific. There is a BAD block in a data file, almost always on the source file(s) and it did not come clean after re-reading it 1,000 times using error correction. The data in that block are unknowable, and therefore the contents of the file containing that block are also unknowable.


One or more of the files involved are dead to you.


Disk Utility Repair is a good idea in general, but it only makes certain the disk directory has integrity. Disk Utility has no additional ability to repair bad blocks.
