Disk Defrag on Extended Drive

In general, DiskKeeper is not a problem as long as it is only being used to defragment an Extended Disk.

Please note, there problem is the ¿UD Filter¿ which is part of Undelete for Diskeeper is causing the Extender Drive to report internal error 15.  The software creates a recovery bin on the drives and can confuse the DX drivers.

Therefore, I strongly recommend that you run this utility on a Test system first before proceeding.
