How do I fix issues with a pool's recycle bin

A corrupt recycle bin is generally caused by a mismatch of the recycle bin folders across the drives in the pool. The following details a number of methods in fixing this issue.

Method 1, deleting the recycle bin.
a) Open explorer and then the options menu (use the ALT key to show the menus). Enable show system files from the option menu.
b) You should now see the recycle bin folder on the pooled drive, select it, hold down shift and press delete. This will delete the corrupt folder and Windows will recreate it when needed.
c) Show the explorer options again, select "Restore defaults" to ensure system / hidden files are no longer shown.

Method 2, deleting the recycle bin from each individual drive.
a) Open explorer and then the options menu (use the ALT key to show the menus). Enable show system files from the option menu.
b) Under the root of the drive you will see a sub folder similar to "PoolHD.{12345-12345..}", this is the root of the pooled drive (if there are more than one mount points in the pool, there will be multiple sub folders). Open the folder, here you will see the recycle bin, select it, hold down shift and press delete. This will delete the corrupt folder and Windows will recreate it when needed.
c) Do this for each drive in the pool.
d) Show the explorer options again, select "Restore defaults" to ensure system / hidden files are no longer shown.

If either of these two methods fail, there may be an issue with a locked folder, or a bad entry on the drive. Use chkdsk to scan each drive in the pool to ensure their structure is ok.
