Multiple Drives at once?

Defraggler
1

Why doesnt defraggler defrag multiple drives at once? I found a post on the internet saying windows7 internal defrag can do it.

I also found a forum post saying defraggler can do it, but i dont see it?

Whats going on?

Defragging multiple drives (partitions) on the same physical hard disk is slow but it we are talking about different physical disks then it would be okay.

i meant physical disks. why donti have the option when windows defrag can do it, and why do people tell piriform defraggler is capable of doing so?

i want to save time.

Defraggler, I believe, can defrag multiple drives, just not simultaneously.

In the drive listing window, if you click the 1st drive you want to begin at, then hold the shift key on your keyboard down, & let go of the mouse.

Still holding shift, click the last drive you want to stop at.

Defraggler will defrag in sequence.

I agree with El Pusher... Would love a multi-drive option that defrags multiple drives at once instead of sequentially, just be sure they are actually different drives, & not partitions.

Win7 Internal Defrag utility has a command line parameter /M which runs it in parallel in the background for all listed volumes.

Its not that hard to find out to which disk a volume belongs.

Here is complete C++ sample code to find physical drive names

I also hear SetupDiGetDeviceRegistryProperty and SPDRP_PHYSICAL_DEVICE_OBJECT_NAME.are a way to do it.

Well, i guess the devs @piriform are competent enough to do it.

Like all defrag tools it has to utilize the Microsoft Defrag API so I'd imagine it wouldn't be difficult to include. It's just a matter of rather Piriform wants to include it.
