I've been hit with a spat of drives that "lost it all". Later the common factor in all of them was the FAT32 file system. Turns out (and nothing new here) that the owner insisted on that old file system and since it's not that robust suffered the total wipe out.
If you are going to do this, consider a newer file system. Or at least don't complain if it goes missing.
So I am pretty sure that I will need more hard drive space for my laptop, so I was thinking about getting a 3.5 inch hard drive enclosure and keeping it on my desk. This way, I can save all my media (movies, games, music) on this hard drive and just have my operating system and program files on the internal one. What I was thinking, however, was of buying multiple smaller, cheaper drives (~40gb) and keeping my files on separate drives (i.e. my music on one hard drive, games on one, and videos on one). I have never, however, seen one of these enclosures in action, so I was wondering if it was practical to be switching out hard drives fairly often? I haven't yet decided on an enclosure, so I'm just talking generally. Thanks!
