Within the last week I upgraded my older macbook (one of the last black plastic shelled models) to os x lion. Since then I have found that anytime I delete something from my Time Capsule (which I use as an external hard drive for my media) that was on the Time Capsule prior to the upgrade my computer freezes up, spraining beach ball of doom never stops and can't do anything other than move the mouse around the screen. This problem does not occur with items that have been loaded onto it since the upgrade, and short of reuploading all the content on the drive (which is not really an option since it is close to 900 gb) I have no idea what to do in order to prevent this from happening. Any help or advice would be appreciated.
