I understand the concept of Terminal/command line,
Good what you need to do is simple, you just need to be precise.
Is this procedure risky? My data is well backed-up (though in several places, so would be tedious to put it back).
Any time you use sudo in the Terminal it can be risky but having backups removes a lot of tension.
If re-formatting the drive and beginning again is better for long term stability, I could do that.
Don;t think that is necessary at this point but it might be needed if this doesn't fix the problem. Lets see what happens.
OK, read all this before staring. If you have any questions or something doesn;t make sense post back before trying it.
Open a Terminal window (/Applications/Utilities/Terminal)
(the first set of commands is to get you comfortable with the procedure and to make sure the .Trashes folder is where we believe it to be)
enter ls -ld then drag in the icon for the RAID 0 volume you should see something like (with your volume in there)
Pandora:~ frank$ ls -ld /Volumes/QQ
Note there will be a space after the volume name. Use the delete key to delete the space then enter
/.Tra followed by the TAB key (on the same line)
The TAB key will cause the .Tra to expand to .Trashes if the folder is there. Assuming the folder name expanded
you should see
Pandora:~ frank$ ls -ld /Volumes/QQ/.Trashes/
If it doesn't expand make sure you typed in everything as I showed and try again. If it still doesn;t expand post back with a screen shot of the terminal window.
now press return. You should see
Pandora:~ frank$ ls -ld /Volumes/QQ/.Trashes/
d-wx-wx-wt 2 frank staff 68 Jun 2 13:43 /Volumes/QQ/.Trashes//
Pandora:~ frank$
If all that goes OK. Now you'll delete the folder. Enter
sudo rm -rf then drag the RAID icon in again. Again use the delete key to delete the space after the volume name and enter
/.Tra followed by the TAB key. Agina it should expand to .Trashes
Pandora:~ frank$ sudo rm -rf /Volumes/QQ/.Trashes/
Now press return. If this is the first time using the sudo command you'll get a message telling you to be careful. Continue. The .Trashes folder should be removed.Rerun the ls -ld ccommand from above to make sure it is gone.
Assuming it is unmount then remount the volume and the .Trashes folder should be back with the correct permissions. Try deleting a file from the volume and hopefully it will work as it should.
Again if anything here is unclear post back. Also keep in mind that the output you will see will not be identical to the above. Name, dates and prompts will differ.
