Totally worth it! A new Mac for $31!

OS X Mavericks made my 2011 MacBook Pro i7 literally three times slower across the board: starting apps, browsing photos, working in the UI... Although repairing permissions via Disk Utility helped by 5%, a super-easy overnight iDefrag run restored my system's old snappiness. Some of the low-level system files had hundreds of fragments. HATS OFF, CORIOLIS!

After updating to Mavericks, my iMac was running nice and fast. But now two months later, it was nothing but pinning beach balls, a unresponsive Finder which took minutes to draw in a window, and a bunch of other issues.

So I decided to wipe my drive and do a clean install of Mavericks, and then restore everything else from my backup.

That helped a lot, but still, it wasn't running like it should be. So I booted from a maintenance partition, and checked it out with iDefrag. Even though I had just installed everything, it was pretty fragmented. So I ran it over night and now it's as good as new, with Finder windows snapping open and their contents drawing in almost instantly. Applications launch much faster now too.

Isn't wiping one's drive disk and reinstalling an OS the ultimate defragging? That is my understanding anyway. If that's not the case, please enlighten me -- I say this earnestly.

Are you intimating then that restoring your files from a back up caused the fragmentation problems?

You would think so, right? It was not in my case. It probably would have been if I also reinstalled all my software, etc.

But since I restored from a backup using Carbon Copy Cloner, it seems to have moved everything over in the state it was. I think CCC does a block by block copy, and restores the same way. I'm not exactly sure.

When I checked the drive in iDefrag, the newly restored drive was fragmented. Not as bad as it was (it was really bad to start with), but it still showed quit a bit. It only had to run about 8 hours, and the performance improvements where worth it.

RN,

Thanx for the reply. That was my hunch, that restoring ala CCC might reintroduce some of the fragmentation of the original file system.

Ok. So you work with a lot of people using a lot of computers. Therefore we should just accept your view that this is a "complete waste of money"? Why? What makes it a waste of money? What about this particular app is not useful to you and the many thousands of people you work with?

Some of us actually read these reviews/comments hoping to gain insight into How the app does or does not live up to its value/worth. What you wrote is not helpful in that way and, since I do not know you personally, I just simply cannot take you at your word.

I have to respectfully disagree, and I generally agree with all your posts.

What are your users doing with their Macs? I record multitrack audio, and defraging the record drive is essential or you can get errors because the drive is too slow.

Also, OS X gets severely fragmented. The Hot-File-Adaptive-Clustering only works for small files. For people doing multi media it pays to defrag your drives.

I don't do it frequently, since drives these days are so large it takes forever, but you will notice improvements in performance.

Sounds like you need to get faster/larger drives, instead of spending money on this sugar pill.

Any perceived benefit from buying this sugar pill is short lived, and doesn't resolve the root issue.

Don, I have a very fast 2 TB Firewire 800 drive, 10,000 RPM. If you follow any of the DAW products, they will inform you that the drive needs to be defragmented since the software wants to write in contiguous steams, rather than jumping around looking for free sectors. That slows down your reads and writes. You do realize that's how hard rives work, right?

This is also true for video editing.

For smaller files, like word processing, email, or what ever, it doesn't matter. But when you are doing multi track audio you are writing very large files that can't be interrupted. The Mac is also reading multiple large files at the same time.

You can do some benchmarking and prove that the read/write time is improved with a defragmented hard drive. I would do that before dismissing it as a sugar pill.

RavenNevermore replied on 18 Nov 2013
Sorry, but no. That has nothing to do with recording multitrack audio. The DAW writes directly to the drive. Why would it use a second drive?

Maybe you are thinking of RAM buffers? RAM is faster than a mechanical hard drive, so the DAW buffers writes to RAM. However, if you increase your buffers too large, latency goes up, and then trying to play along with recorded tracks sounds noticeably out of sync. That makes overdubbing very difficult.

Scratch disks are for programs like Photoshop to use for temp files and as virtual memory. But Photoshop is not doing anything in real time. DAWs are reading and writing in real time with very low latencies (delays).

You also mentioned:

"I have a very fast 2 TB Firewire 800 drive, 10,000 RPM."

Does this mean you're booting from that drive? Or if that's the drive that you need the fastest performance from, I suppose you're storing data on it, else why not simply initialize (and store your jobs elsewhere)?

No, you never record to your boot drive. The performance would suffer. Some software, like Pro Tools, won't even let you record to the boot drive.

OK, so if your application isn't writing to your boot drive, but you're having to "defrag" your work drive, it sounds like you're using a drive for both storage and work space. Sound right? Storage space is critical, so some sort of RAID1/5/etc is needed for protection...whereas work space can (and likely should) be RAID0 (striped) for highest performance. In this scenario the RAID0 drive would be initialized to "defrag". RAID0 is never used to store data, since it's got multiple points of failure (each disk plus the stripe), but it's fast as heck. It's the RAID0 disk (per se) that I was referring to as "scratch disk". Not sure if I worded that right. It's getting late, my brain is getting fragmented...time to go home. ;)

RavenNevermore replied on 18 Nov 2013
Yes, a RAID would be faster, but it's common to use a regular Firewire drive, since it's often brought from studio to studio, etc. :)

The Firewire drive is just from recording audio to.

After my MacBook Pro 17" (2GB RAM, 300 GB hard drive, 2.16 GHz Intel Core Duo, version 10.6.8) started to show very often spinning "beachball", I decided to repair it with TechTool Pro, with Drive Genius and with DiskWarrior. None of the mentioned did help!
I took iDefrag, and after a long period of time during full defragmenting my OS was repaired and it does not show spinning "beachball"!
So, my conclusion is, no matter iDefrag does defragmenting very slow - it does a fabulous job. Thank you iDefrag!

Neutralzone replied on 03 Nov 2013
A utility that could defrag a Fusion Drive would have to be able to address the drive at a lower level than the OS, because to the OS, Fusion looks like one big drive. The utility would have to be able to look past that because it must be smart enough to completely avoid defragging the SSD, since defragging an SSD is literally a complete waste of time, and shortens the life of the SSD.

Also, if the point of defragging is to speed up disk access, then there is no point in doing it to a Fusion drive. The normal operation of the Fusion Drive is to automatically move files you are actively working on to the SSD, and the performance gain from this everyday function of the Fusion Drive is massively larger than the minuscule performance gain of defragging the HDD portion of a Fusion Drive.

Some "user friendly" companies milked OS X major version upgrade incompatibilities for ages, going far as $100/year "update service". One even tried to charge for their own bugfixes. Lets not name anyone.

What I see is, someone who purchased iDefrag back in OS X Tiger can still run it (with all bug fixes) on Snow Leopard. That is something unheard of... Only Alsoft (makers of Disk Warrior) does a similar thing.

If you want pure 64bit application with improved algorithm and _additional, new features_, you pay $14. If you don't? Well, the "unfriendly" developer is decent enough to maintain 1.x version.

As a previous reviewer noted, running iDefrag on a Mac with Time Machine enabled results in Time Machine backing up many of the defragged files. Too bad I didn't realize this before I ran iDefrag. Time Machine is now backing up a whopping 371 GB of files, none of which have actually changed. My 1 TB Time Machine volume was full, which means I have now lost a whole bunch of backups from several months ago so that Time Machine can squeeze in 371 GB of not-at-all-new files.

Because of this, I will no longer be using iDefrag. I'd rather have a fragmented disk and keep my old backups.

The problem here is probably that you have the temperature parameters set incorrectly in iDefrag's Preferences panel. Some disks are quite capable of operating at up to 60°C (possibly in a few cases even higher), whereas others are not; the default values in iDefrag's Preferences panel are, necessarily, conservative.

You can find out what the maximum operating temperature for your drive is either by looking up the serial number (in Disk Utility or System Profiler) and sending it in to us, or by looking on the hard drive manufacturer's website.

Alternatively, and obviously at your own risk, you can disable the thermal monitoring feature in Preferences.
