Hi. It depends on what type of pen drive your looking for. If your looking for just a standard pen drive, they should be compatible with both xp and vista with no issues arising. If your thinking of buying a smart pen drive such as a U3 drive, you'll need to check that any applications you install on it are up-to-date and are compatible with vista. In some cases, you will also have to update the U3 launcher software as the preinstalled version on some drives is not compatible with vista. An updated version is available at www.u3.com. Hope this helps. ----- Original Message ----- From: ANDY COLLINS To: access-uk@xxxxxxxxxxxxx Sent: Sunday, January 04, 2009 3:57 PM Subject: [access-uk] pen drives Hi all - I'm going to end up with a vista laptop and an XP netbook; I'm thihnking of getting a pen drive to transfer data, are there different kinds of USB pen drives? Are there any compatible issues? Also, are pen drives just plug and play, or do they need to be configured in some way? Thanks - Andy
