We were copying about a terabyte from an SMB-based shared on a Mac running Intel 10.6 to an USB-connected RAID 0 APFS disk. FFS said all the files copied but these two. We could open and play them and when we recopied them with FFS, they copied fine.
What could have caused these errors for just these two files?
How come FFS proceeded to try subsequent files and the connection came back alive for them (only these two had errors (out of perhaps 100,000)? Coincidence I guess that they were avi files.
It's really hard to say without being able to reproduce the issue... Maybe those files had some type of lock on them preventing any access? Maybe antivirus was locking them down until it finished scanning them for threats, which can prevent them from being deleted or read? If it was a Windows-based server, I would check Event Viewer for a start, maybe there is a Mac OS equivalent
The files were not locked. We simply mounted the share and started copying files. There is no antivirus on the Mac. The Mac is the client. The server is IBM proprietary, not Windows-based.
