- Can you provide more details about how you reproduce this issue?
- What happens if you run the same AzCopy command directly from the command line? Does the failure still occur?
- 4 TB is a pretty large disk. Do you know for sure if somone else or another process could be accessing the disk you're trying to download?
- Silly question, but does the destination have enough space for the disk? Are you downloading to a network mapped drive.
- Is there any additional information you can provide about this issue?
