I recently started noticing HDD performance issues with my vmware team. The team contains 10 virtual machines with various client OS I support. I used the defragments utility from the vmware settings page for the HDD. The defragemnt completed with no errors. I continues to run the defrag on each of the windows based VMs. Now that i've finished that if I start the VM I receive an error access the the Vittial HDD.

Looking at the file structure it look slike everything is there but i'm not real sure what eash file does so something might have gone wrong. Every VM i defragmented has this problem.

Vmware 6.5, Windoes Vista x64.

Do you have snapshots for each VM which you have defragmented ?

Yes, I have an original config and one i made about a week ago or so. Ideally id like to continue running off the current image and not revert back because the old version was before i made some recent changed i'm testing out.

1.What type of Hard Drives are you using ? (SATA, IDE)
2.Snapshots are not equal to backups. Please delete them as soon as you are done with your tasks.

Physically on the host it's a raid 0 of sas drives. Vittually I'm using scsi for most of the virtuals. Two of them are IDE. Problem seams the same between all of them.

My understanding is the VMDK file associated with the VMs would have got corrupted.

Try using the VMware vConverter 4.0 to convert the Virtual Machine and check whether it is getting powered on.

vConverter is a utility from VMware to convert virtual machines from one format to another.It is available as a free download from VMware Website.
It helps to recover Virtual Machines when Snapshots wreak havoc and disable the ability to power on VMs.

Close, Very close. Uting the reconfigure option was enough to fix some and the conversion fixes some more that were unable to be corrected by reconfigure. Currently non of the virtual machines that had windows xp as the guest os work (2 total). This is strange to me becaue they all stoped due to the defrag but the same solution doesn;t seam to fix each one. If we can get the XPs to start working agian we are in buisness.

As far as the VMs that were repaired I had sucess on both SCSI and IDE configured discs and VMs running Win 2K, server 03, Fedora, Ubuntu, and vista. XP is the only problem child.
