Hi, I upgraded the hard drive in my MBP (4,1 Mar '08) this weekend from a stock 5400rpm 250Gb to a 7200rpm 320Gb WD Scorpio Black... I used Time Machine to restore the system onto the new drive - via a new 1Tb external drive which I first prepped for network use via my AEBS but hooked up via FW800 to do the first backup before upgrading the hard drive. Laptop is fine - everything pretty much seems as it was - but Time Machine isn't. Every backup appears to be of the full hard drive contents (have only excluded the Parallels folder)! My otherwise empty 1Tb drive now has nearly 300Gb of backups of a 140-150Gb disk!! Here's the du stats from inside the /Volumes/Backup of../Backups.backupsdb/..MacBook Pro : 144080500 2009-05-03-000434 142168476 2009-05-03-090644 142754912 2009-05-03-093113 35032544 2009-05-07-025139.inProgress] 3rd May was when I did the hard drive update so it was already doing the full drive backup right away, I had originally thought it was something to do with swapping out the hard drive but that's not so. I haven't been able to complete a backup since as its also incredibly slow. Left the laptop plugged in overnight and it had only completed ~30Gb in about 5-6 hours - over FW800! The drive is OK - I can copy over large files and that goes super fast as you'd expect. Anyone seen anything like this? How do I resolve this? Ideally I'd like to keep at least the first backup from before the drive upgrade. Should I (can I?) move this onto another drive then reformat and start again?
