I've been encountering this error whenever I transfer large amounts (10GB+) of data from my Mac to smb shares on my PC: "The Finder can't complete the operation because some data in "iTunes" can't be read or written. (Error code -36)" After I encounter this error, I can't write/read anything from all the SMB shares I have connected on my Mac. When I open them, they are just blank (like a folder with no content in it) and if I try to write anything to them (even if it's just a single file), it gives me Error Code -41. I also can't disconnect from the smb server. Relaunching Finder doesn't do anything. I have to restart my computer to get it working again. Any ideas? Thanks! Sorry, I think I posted this in the wrong section. Could a mod please move it to the OS X section? Thanks.
