I have 4 TB Western Digital my-passport drive. When I copy a folder with large number of files, the copy (or move files) dialog just sits there forever without returning but no further copying takes place. It usually does copy some files but it gets stuck at some point.
I don't have any particular files that are over 4 GB and file system on drive is also NTFS so it's not an issue of one large file. But what I am copying is a big folder over 15 GB.
When I run "Western Digital Data Lifeguard Diagnostics" tool on the drive, it does detect too many bad sectors. However, I ran windows scan disk with option to repair errors and it doesn't find any errors.
I also went into Device Manager >> "Disk Drives" >> "My Passport" and turned off "Quick Removal" under "policies" tab and changed to "Better Performance" which was supposed to help but it didn't.
So I am confused, are there really bad sectors on the disk that WD tool tells me or the problem is something else and in that case why I can't copy a large folder?
