Copy (not move) the files to another directory they should be in a contiguous file then. Delete the original.

I suspect defrag won't work well over 2gb.

Yes I found that in the list someone else posted. But they all read like they were going to do the same thing, they moved files, not blocks.

So I moved my huge files onto an external drive, defraged the rest and moved them back. Fixed now.

thanks guys

Can any one tell me how I can get my disk deframgmented properly (for free).

Do these defragging tools work on RAID drives? If so I'm curious how.

Presumably they'd have to look past the logical volume and down to hardware level?

Good question about RAID. I would presume it would not make any sense for stripes or parity but would for spanning and mirroring.

Most UNIX filesystems do not need to be de-fragmented; hence defrag takes place at the level of the filesystem rather than raw access.

do you get .flv files that big?

It's a DVD image. You're supposed to burn it onto a DVD and play it back with your stand alone DVD player.

But I don't have a DVD burner (or a stand alone player for that matter), so I'm having to keep them on the PC and play them back using a 'virtual' DVD device.

There's 28 hours to watch, it will be ages before I can delete them (which I will do, I don't archive video footage once I have watched it). They die next week, so I can't delay downloading them until I have time to watch - OK someone will post them again, but I can't be sure when that will be. The three files that I have so far is only half the total.

But anyway, they aren't the reason why my disk is fragmented, but (I think) they are the reason defrag won't fix it.

I know that I shouldn't really have 4 gig rips on my drive, but this was a once only opportunity.

Highly recommend diskkeeper, i got the trial version, it made such a huge difference and did exactly what it said on the tin that i bought it mainly for its background defrag meaning i dont have to do it now and again, it's always optimising the disk for me..

its a business expense

About 40% of the disk is free. It's been well thrashed with torrents so there are used blocks everywhere.

The largest (3) files represent about 5% of the disk (each) and there certainly isn't an empty space anywhere close to this big. But there are lots of small files that it refused to defrag as well, WTF doesn't it move them?

What are the files that defrag fails to work on?

They may be system files (e.g swap file) or they may currently be in use by the O/S.

Try Diskeeper. You can download a fully functional trial version from their website.

Failing that, this list may help.

Could always try a third party defrag tool:

http://www.perfectdisk.com/products/perfectdisk2k/
http://www.oo-software.com/home/en/products/oodefrag/

I don't use either but have heard good things about o&o, it's not free though.

Have you got enough free disk space?


May sound silly but unless you have at lease 15% (I think that's the right number) free defrag won't work properly.
