I used Disk Utility to create an empty encrypted sparsebundle on a FAT volume A. It contains an HFS volume B. I am running on Snow Leopard.
The DMG now pretty much fills A, and I'm fine with that. This is not about space on A.
When I delete files from B, the free space Finder shows for B does not change, and it refuses to copy new files onto B. Emptying the trash doesn't help. Ejecting doesn't help. But verifying (not repairing) B in Disk Utility does, even though no errors are found.
This is a bit of a chore. How do I get better behaviour?
