If you cannot open the files I don’t understand how you can copy them, as the copy process would need to open the files in order to do the copy. Are the original and the copy on the same data disk, or do they end up on different disks?

Possibly this issue ....

As well as the file permissions (read/write/execute) what is owner/group of the problem files? Files copied via SMB will usually have the owner/group of nobody/users. It suspect the ones you copied might have the owner/group of root/root.

See something call "Help" top right of your screenshot? Try clicking on that.

But someone must still be using it as Microsoft pushed out an update this week, separate from their normal updates sequence, on all Windows still receiving updates, specifically for a serious vulnerability in Internet Explorer. Usually my work IT department allows us 7 to 10 days to apply updates before they force it onto the machines; In this case it was only 2 days. Can’t remember the last time I used Internet Explorer myself.

No. Use either the "Include disks" option or "Exclude disks" option (whichever is more convenient), but don’t use both.

While I guess this fix might be rolled into the next 6.7.3 release (now that it look like there will be one to fix the database corruption issues some people have be experiencing), for now if you have the latest CA Application auto update plugin installed it will automatically apply a fix.

the following command will find any empty sub-directories, starting in the current directory: find . -type d -empty and the following on will find and delete any empty sub-directories, starting in the current directory: find . -type d -empty -delete

All parity drives have to be equal or larger than the largest data drive. So your attempt to use the 4TB drive is not valid as you have a data drive which is 10TB. With 2 parity drives you are supposed to be able to recover from 2 failed drives, but if the configuration you are trying to create was allowed and the 2 10TB drives were to fail then you would not be able recover the failed 10TB data drive.

Did you try enabling ‘reconstruct write’ mode (aka ‘turbo write’) to see if that improves your performance on your system?

Is there any difference between the permissions/owner/group of the directory which has the problem files and one which does not? Does the directory name (and any parent directory names) have any special characters in them?

I suspect much of what you have in your go file you should possibly move to running using the "User Scripts" plugin. That then helps to separate your customisations from the base Unraid.

Haven’t tried it myself, but as already mentioned should be readable by virtually any Linux distribution, so install one in a VM on your windows system and mount the USB disk in the VM, then share it via SMB for access from your windows system. In fact, although Unraid is not officially supported in VMs it does work, so you could probably install a trial version of unRaid in a VM and then using the Unassigned Devices plugin to mount the USB disk and share it. This is definitely all something worth testing prior to any emergency with data you can afford to lose in case you do anything wrong.

I would also suggest the plugin ‘Fix Common Problems’ is also highly recommended .... I suspect it would have flagged up your original problem with your cache settings. This plugin is excellent at flagging up common configuration issues and is continually improved as new issues are identified.

Any bets that when you get the Diagnostics you will find that the cache has been set to ‘Prefer’ rather than ‘Yes’ so Unraid is trying to move files to the cache drive rather than from it?
