Disk Defragmenter Command Line Switch?

JamesJ · External Since: Apr 02, 2009 Posts: 28

I'm trying to get Disk Defragmenter to analyze only 1 disk at a time
but can't seem do do it. I'm using the following but when it starts
analyzing
in reports Analyzing disk 1 of 2:
%SystemRoot%\system32\dfrgui.exe c:

I have an external hard drive but I don't want both drives to be analyzed.
Even when I got to Computer and right click c: and select Properties|Tools
Tab
and 'Defrag now' it analyzes both drives.
Any way I can get Defrag to address only 1 drive?

I'm using Vista Basic sp2.

My defragmenter has a choice to select volumes or all drives.
I'm using Vista Home Premium.

From the moment I open defragmenter it begins analyzing my drives.
I get no opertunity to select a drive.

My best guess is to shut down, disconnect the external drive and reboot.
Then do a defrag.

I found out that it analyzes both drives upon opening, but when I select
Defrag now...
it then gives me the opportunity to select the drive(s).
I was a bit concerned that it would defrag both drives without any input
from me.
Must be by design.

Thanks much,
James

CMD prompt

type:

defrag_c:_-w_-v

_ = spacebar

this will defrag the c drive and give a full report B4 and after
