defrag program recommendations

what are your thoughts? so far i've heard of diskeeper, o&o defrag and perfect disk. anyone have any suggestions on a good one i haven't heard of, or any comments on the quality of the ones i listed?

Use ext3, you won't have to defrag.

Yes you will; have you ever wondered what the non-contiguous% thing means that is displayed during fuck(8)?

Linux doesn't require defragmentation because it doesn't fragment its files in the first place.

From Wikipedia, the Lunixfag basher:

Defragmentation

There is no online ext3 defragmentation tool working on the filesystem level. An offline ext2 defragmenter, e2defrag, exists but requires that the ext3 filesystem be converted back to ext2 first. But depending on the feature bits turned on the filesystem, e2defrag may destroy data; it does not know how to treat many of the newer ext3 features.

There are userspace defragmentation tools like Shake and defrag, which work by copying each file and hoping the newly allocated file was not fragmented. However this only works if the filesystem is reasonably empty, and such filesystems are not usually fragmented. A true defragmentation tool does not exist for ext3.

Also >>4? Defragmentation is an essential part of hard drive storing.

ext3 and ReiserFS don't need to be defragged.  Stop thinking inside the box pl0x.  They don't fragment their files in the first place.

Dammit, what are you talking about? Of course they do! Can't you read your own links?

Linux partitions using common Linux FSs generally don't need to be defragged.  This is so for two reasons:

1. The OS is multi-user.  Files are going on and off the FS all the time.  File fragmentation tends to be transient.

2. The FSs fragment the DISK by default, which leads to less fragmenting of FILES.

However, a single-user system will tend to accumulate more fragmented files.  Also, as the disk fills up, the problem becomes worse ... which is true for ANY FS, NTFS included.

I would never defrag a Linux FS like ext2/3 or reiser.  At best, every so often, I would identify the largest fragmented file, copy it over to another partition, delete it in the original spot, then copy it back.

Having space AROUND files is the best way to manage a FS.  The DISK should be fragmented, so that the FILES will be minimally fragmented.

Truth.

And if all else fails, tar everything up, format the partition and copy the stuff back from the tar.
