defragmenter is already running

[Guest George Valkov]

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!

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 local volumes.

.. 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:

Re: defragmenter is already running

 

Thank You for your answer, Mathieu!

I shall try Diskeeper trial in a test environment, to see what features it

has, but I will probably not move to it.

The two hard-disks on my server are large and have many files, but are also

fast enough, so the defragmentation takes quite a little time.

The good arrangement of "dedicated for specific task" partitions and the

large cluster size of 64 KB also speeds the defragmentation and reduces the

fragmentation during disk usage.
