Okay, this is showing huge ignorance, but here's my question: I only intend to put my own CDs onto an mp3 player, rather than download music. My PC has a tiny hard drive (6gb!), so I've copied loads of CDs into mp3 format, then transferred them to data CDs and removed them from the hard drive. With my old Zen Mmicro I simply copied these albums from the data CDs onto the player, no problem. However, I've read reviews of some machines which imply to me that they synchronize with your PC when connected and automatically update from your PC's library (the Zen didn't do this). Now, I'm worrying that it's possible that some mp3 players will automatically remove any albums on them if they find they're no longer on the PC when the two are docked. Is this a huge misunderstanding on my part? Will I be okay with the HD5 to "load it up" with albums from my mp3 data CDs? Thanks for your help.
