This is a strange one. I've been doing some work with our Windows 8 64-bit parent VM, and I noticed that I was running low on disk space. So I deleted all of the snapshots on the VM, then increased the size of the hard drive and extended the partition to fill the volume within Windows. That seemed to go just fine, and I had a lot more room on my C drive, so I was happy. Later, I tried to defrag the drive using the Optimize Drives utility and, as you can see from my attached screen shot, Windows 8 believed that I had an SSD drive, which I don't. I just have a traditional SAN with 15k SAS drives. The odd thing is that I can defragment the drive using the command line utility "defrag C: /U /V" and it works just fine. But within the GUI, I'm given the "Optimization not available" message. So, I took a new snapshot of the VM and deployed a pool of linked clones from it. They deployed fine, and I'm logged into one of them now, and I have the same message in the Optimize Drives utility. It doesn't appear to have any effect on the operation of the VM, as it works just fine in all other respects. I'm sure that it's related to my expansion of the C partition. Has anybody else ever seen anything like this before? I'm sure that I'll have to recreate my parent VM eventually, though this one is working fine for the limited test users we have on it for now. If anybody has any suggestions on how I can get this back to normal, I'd appreciate the help.
