Hello,

you can't run two defrag with the builtin windows program. You may use third party software to achieve this.

.. It can defragment only one volume at a time.
.. It cannot defragment one volume while it is scanning another.


Take care that you may loss Shadow copy when defragmenting volumes:

I understand that running defrag.exe utility on two partitions which are on
one and same physical hard-disk is a bad idea.

What about defragmenting two partitions from two physical hard-disks in
parallel. I think that this will require less time to complete the batch
job.
1. Am I correct?
2. Can I workaround that restriction and run two instances of defrag.exe at
the same time?


I always do this with chkdsk.exe:
A script "chk2.bat", when executed it spawns an instance of it self for each
physical disk. Each instance checks the partitions of it's disks one by one
and notifies the main instance when complete. When all spawned instances
complete, the main instance restarts the server, to check the remaining
locked partitions (system and page file).

I want to do something like that, but with defrag.exe.


Thank You for any help!
