What is VMOptimizer? Well, being able to run other operating systems without having to restart your Mac is undeniably useful, but over time performance can degrade which can be frustrating if you're trying to run a game. You might have been able to improve this performance by running a defragmenter such as iDefrag, but that only solves part of the problem.
Most files only suffer from one kind of file fragmentation, but virtual disks suffer from three different kinds of fragmentation which means the performance degradation caused by it is multiplied. Now it is possible to

Most files only suffer from one kind of file fragmentation, but virtual disks suffer from three different kinds of fragmentation which means the performance degradation caused by it is multiplied. Now it is possible to tackle each kind of fragmentation individually, but that's awkward and time consuming. Things get even more complicated when you add the fact that virtual disks are usually split into many files and they might be using snapshots.
This is where VMOptimizer steps in. It quickly and efficiently tackles all three kinds of fragmentation in one go.
VMOptimizer is also able to make other optimizations that can significantly boost performance, such as realigning partitions that happen to be misaligned.

Like some other's I had problems with defragmenting an XP VM but the guy's at Coriolis were extremely helpful and had the issue resolved in under 24 hours. Great support from a company you can trust.
As with iDefrag I always notice a significant improvement after running a defrag. I have VM's for Ubuntu 11.04, Fedora 15, Win XP and Lion and VMO made a visible difference to all of them.

Well, in a misguided moment I went to purchase this product, did 'optimize' my well functioning XP/VM drive...
OK, now its dead... RIP...
Did a restore from my last Snapshot, lost about 2-3 days of work and another 5 minutes to kill off the VMOptimizer from my system....
Oh, forgot to mention, that the backup copy of my original drive (which VMOptimizer left in my Wastebasket as backup) is also not recognized by VMware as valid file anymore.....
As I said, a misguided moment, I should have known better, the blame is mainly on me.....

HINT: I don't know if the tool automatic checks Volume (were the virtual file stays before starting any changes.
I used and use idefrag (same company) on that files often without any problem, but always checked and repaired that volume before i run idefrag on it.
If also your backuped vmware images won't run, there must be something other beside that tool task.

The XP volume was perfectly functioning before the optimization, as a matter of fact the only reason to optimize was the hope to gain a little but performance .... :-)
But well, it was a usable file without any troubles so far.
The 'optimized' image did instantly run into a fsck and after that tried to startup, but had quite instantly a bad checksum on some file and ran into a loop restarting. I couldn't see the error message long enough to identify the corrupted file, as it just shortly was displayed and immediate thereafter the startup screen was back... infinite.... :-)
The 'backup'-file in the wastebasket was moved by the application VMOptimize (it states somewhere '...moved just to make sure in case something happened which is most unlikely', something like that) so I strongly believe this file had nothing to do anymore with my original image, as this was functioning properly before.....

Please get in touch with our support team if you haven’t already. It might be too late if you’ve deleted items from the Trash, but we can give you instructions for recovering your Virtual Machine. Nothing will be lost.
I've just fixed a bug that might have been the one you were seeing. It doesn't affect all virtual machines, just virtual machines in a certain configuration.
Obviously we’ll give you a full refund.
We’ll release an update shortly. Sorry for the inconvenience this has caused you.

thanks for the prompt answer, and no problem refund isn't necessary.
And yes, things can go wrong, but if responsive actions like yours are taken in short term its cool....
And as I said earlier, I myself was quite careless not to make a clean backup myself before such an action.... :-))
I think I still got the file from the wastebasket, so I will get in touch with your support offline, but I have already kind of recovered by using an older Snapshot...
Best regards

OK, I've released an update to address the problem that I found.
Please do get in touch with us via our support e-mail address as there’s a chance it’s not the problem you were having.
I’d like to make a couple of points to anyone else reading this:
1) There’s no chance of losing data—VMOptimizer leaves the old files in the Trash and it’s easy enough to restore from the Trash (but you might need us to give you instructions).
2) If customers do encounter a problem, please contact us via e-mail. We usually answer e-mails within 24 hours (except over weekends) and we can usually resolve issues quite quickly. We occasionally check sites such as MacUpdate but we don’t guarantee that, so don’t expect to get support via this or any other site.
Once again, sorry Hubert for this problem. It’s as upsetting to us as it is to you when things like this happen.
Kind regards,
Chris
