I replaced a 100 gig SATA internal drive with a 1 terabyte drive a month ago. I replaced the old drive because I needed more room for Windows 7, which I'll be installing in a dual boot with Win XP. I also have a 500 gig PATA in that computer, which I use primarily for Linux and for backups of the SATA drive. I have five external hard drives: three are 200 gigs each, one is 500 gigs, one is 160 gigs. They are pretty full of backups (for three computers). I have to delete old backups when I'm making a new one. Your computer BIOS does not limit the size of an external drive. What might limit it is the external case itself, which has some sort of BIOS of its own, though I'm not sure that's the right term. You'd have to be sure that the external case would support a terabyte drive. One of my computers does not support 48-bit LBA for sure, but it has no problem with the 200-gig external USB drive when I attach it. I'm sure my old laptop doesn't have 48-bit LBA (it's six years old and has a 40-gig drive in it), but it likes the 160-gig Firewire external I use with it.
