Error Code-50 when trying to copy or delete files on external hard drive
Hi,
I am in process of backing up large HD video files from one external hard drive to another using Carbon Copy Cloner software. I get this error message: "This file or folder is sitting on a bad section of hard disk media and is unrecoverable. Delete this item (i.e. in the Finder) and restore it from a known good backup, then try the backup task again."
- I have tried to delete that folder in Finder and I get error code-50, it won't delete.
- I tried to delete individual files within folder - error code 50.
- I tried to "replace" folder with good copy from other external hard drive. Error code-50
- I tried to "repair disk" in Disk Utility application and I get error message "cannot unmount disk."
- NOTE: the files in this folder are .m2ts format, from an old PC. I converted then into .mov but want to retain originals.
- NOTE: I was successfully able to copy the folder from a 3rd external hard drive to the backup disk without a problem (which makes me think it's not the files/folder but has to do with the actual disk.), but cannot fix it on the original (source) disk.
Bad disk?
Bad files?
How do you fix a "bad section of a hard disk"?
Might reformatting the entire disk fix the "bad section"?
Any advice welcomed and appreciated!
Thank you!
