I plan to use my Passport to store music files, not as a true back up device. I was able to copy all my files onto the device and can access from my home computer but when I take the device to work and try to add more files from my office computer it doesnt recognize the existing files or allow me to add more.

Am I doing something wrong? Arent external drives able to do this?

What OS is your PC and office PC and how is the drive formatted? Does the office PC have external access blocked for security?

Both computuers are running XP.  The file type on my home computer is NTFS, the one at the office is UDF. There are no restrictions for external devices at the office. How can I get the office file type to match?
