Deleting snapshots is looping

I am trying to delete a snapshot in Parallels 4.0 (after converting from 3.0). The delete command has been looping for 15 minutes. Is this unreasonable and if I Force Quit to get out of it, will the virtual disk image be damaged?
 
If 'time' is not a factor my 'best guess' would be let it ride for a while - I have never had that hang up for me but then I can't honestly say I sat and timed it either. I would initiate it and go on to other tasks.

Sorry I am not more help!
 
Thanks for the comment. I've now searched back in previous threads and find that deleting a snapshot can take up to 3 hours - without any prior warning and without any progress bar - not a very user friendly interface. Also, there was a warning from one of the Parallels experts NOT to delete a snapshot with the VM running - although why there isn't a software interlock against doing these defeats me.

Unfortunately, I did the delete command WITH the VM running so by the time it finishes, I'm guessing that my .hdd file may have been corrupted. Thank goodness for backups.

Latest news: the snapshot delete DID finish in 50 minutes and I shut down and restarted the VM successfully.
 
I am very pleased to hear you did not lose your VM (and glad you had a backup in case you needed it)!

I think the time it takes likely is dependent on how large your VM environment is (??? that is a guess) or perhaps it is dependent on the horsepower of the mac you are running!
 
Yes - it's hard to say what the cause is. After gaining confidence, I deleted 4 snapshots. The VM was 28GB at the start, 24GB after the first delete, 17GB after the second, 13GB after the third and 8GB after the 4th. Each delete took the proportionate time equivalent (about 200MB per minute). My CPU is a 2.02 GHz C2D with 2GB memory.

It would be nice to advise the user beforehand so that impatience doesn't take over!

Thanks for your thoughts.
