The datastore has plenty of space. so i'm going to backup everything and then see if I can attach to anohter VM. Also, how can i be 100% sure that when i deleted my snapshots that they are no longer in use?
Also, if i attach to anothe VM, will this VM crash too because that hd is full?
100% certain, identify date\time file stamps. If the VM will not boot, it's not getting that far.. you can always rename a snapshot boot the VM, if the VM does not boot after the snapshot change, but did before, there is your answer. 100%. If it does boot, now you can safely delete the snapshots.
Windows OS will not crash, only the boot or place where paging is stored, that will cause OS to freeze.. but not usually crash. So attaching a full vmdk to a running VM should not cause that running VM to crash, the VM will see the newly added disk as simply data.. it has no reference or connection to anything on that drive.
