First of all thank you very much for spending your time with my problem.
I had a crash on my HDD with XP and so I wanted to make a backup of my old but still very useful Vx using the laptop of my wife (Vista).
I installed palm software and performed two hotsynch. Apparently everything OK, even looking at the log file but I was not able to see the backup on the HDD. My old data were still on the palm.
I run the palm desktop programm and tried another synch. At this time it took a much longer time and when it finished... all my data on the palm were gone, except for the files of a third party commercial software that are the only one survived!!!
By carefully checking the HDD I was able only to find a backup directory but still no phone and memos records.
Older Palms are not compatible with Vista. Not even the Access Desktop for Vista will Hotsync the older Palms.
The Backup folder only has 3rd party apps and data. You should look for the Address, Datebook, Memopad and ToDo folders, they contain your PIM data and are in the same parent directory that looks like your UsreName. But the backup of these is overwriten at the end on the Hotsync so that they reflect what was Hotsynced.
Your data is gone unless you have another copy of your Username directory.
All of your data (as of your last synchronization) is contained in a folder on your desktop computer named after the User Name you assigned to your handheld device. On a Windows computer you can usually find the folder at C:\Program Files\Palm\ .
