It should not be that hard. BTW, check out the dear mr. Jobs letter on my blog. Looking forward to 2.0! Why not just replace the drive. It should not be that hard. BTW, check out the dear mr.

Shouldn't be that long. The slug thing is something I'm still considering. But first I want the 100mbit wifi to become available ;-).

It basically makes a clone copy of the entire filesystem, and keeps it synchronized as well. Nice job so far. One other option is to use rsync, there are several tutorials out there to make a real bootable clone copy, such as this one: http://www.egg-tech.com/mac_backup/ For my system backup, I use a 2.5" firewire+usb external drive so I can do a straight-forward physical swap of the disk in case of an unfortunate hard drive crash. All my 2.5" hard disks are 5400 rpm ATA100, 60GB and 80GB, from Western Digital and Seagate. For my data backup, I have an external 3.5" drive (firewire 400 and usb 2.0). Additionally, I use a NSLU2 to provide drive shares over my Wifi LAN. ;) SuperDuper! is nice indeed, but I use Intego’s PersonalBackup (http://www.intego.com/personalbackup/) to backup a copy of my current Mac OS X Tiger system.

Meaning that a at a given density it matters, but that a 160GB drive that spins at 5400RPM will actually be able to perform sequential reads as fast if not faster than a 100GB drive at 7200RPM. Of course, at a give size, RPM does improve things...and it'll always help seek times. But RPM isn't everything these days.
