Cannot synchronise - missing time stamps

[Pachuco]

I wonder if anyone has any suggestions. I have successfully upgraded my Zen Xtra 60 GB with VMware running XP SP2 in Windows 7 - thanks to everyone here who made that possible!

The only hiccup I have is that no time stamps are made for neither "Created" nor "Modified", whenever a file is transferred to the unit.

A significant consequence is that I cannot synchronize - everything is always copied from scratch!

I've tried the following:

- In Recovery Mode: Reformat All and Reload OS
- Clean Up
- Synchronized with different programmes (i.e. MusicBee, WMP, WinAmp)
- Same issue if I just do drag-n-drop in Explorer (i.e. mentioned attributes remain empty)

Just to make it very clear - all my MP3 have time stamps when viewed in Windows Explorer.

Any ideas?
