disk compressor not working

[mdporter]

Parallels 5, I have a disk image that could be 12 gigs smaller if compressed. No snapshots or undos. Clicking the Compress button in the disk settings does nothing. I get a progress bar for about 5 seconds and left back at the disk settings area, no error messages are given.

My free disk space on the mac side is low, only 4 gigs free.

here are some errors from the os x console:

Another data point to add... the VM that won't compress was created with parallels version 3, upgraded to version 4, and then upgraded again to version 5.

I tried another VM that was created with version 5 and it compressed with no issues using the same command sequence outline above on the same host.

 

[mdporter]

parallels support, do you have any ideas on what I can do with this?

 

[mdporter]

Does parallels support read the forum, or is it just us users now?

 

[I-che]

What is the size of VM that doesn't compress? Total virtual hard disk size?

I just upgraded to Parallel's 5 (started at 3). Cannot compress. The message I get is that the disk is corrupt, or there are snapshots (there are none). Substantial disk resources can be saved if this is resolved, please advise.
