I have a Handspring Visor
If you have hotsynced your Visor with a PC (or Mac), the first time you sync your Visor to that computer, it should restore all the data from the last hotsync to the PDA. This is one big reason that it makes sense to sync your PDA on a regular basis.
Unfortunately, if you never used the hotsync function for your Visor, you may not be able to recover any of your data. This model Handspring Visor requires good batteries or else everything in its memory will randomize and you will lose all stored information. There is a small capacitor in the Visor that provides enough reserve power for about 30-60 seconds when you pull out the batteries. It's for this reason that Palm recommended pulling out only one battery at a time when changing to a fresh set. That minimized the amount of time that the PDA would be without power. That same advice applies equally to Visor PDAs.
