I feel rather silly asking, but don't want to screw anything up, so here goes. My iMac 20" (2006) was running slower and slower as well as having various errors pop up, so, fearing the HD might be going, I went out and grabbed an external HD and started using Time Machine. Backed up nicely, took the computer in and I did need a new HD. The new HD is in, the new OS (10.5.8) has been fully updated and it's just a completely fresh install - I've done nothing yet. Now I want to get all my data off Time Machine but I'm not sure the best way to do it! 1) I plugged in the drive and first, it asks if I want to use the drive as my Time Machine backup. If I do that, will it write over my old backups? 2) Since I was having troubles with my old version (I can't be 100% sure everything was caused just by the old HD slowing down, I assume), do I really want to restore the whole latest version? 3) If so, or even if not, how do I do that anyway??? Do I say "yes I'd like to my make drive be the Time Machine drive", let it do the backup, then restore somehow? Use Migration Assistant (I've read about that but not tried it)? Something else? Please forgive the newbie questions - never had to use Time Machine before (but darned happy I have it!) and don't want to screw up my nice, fast-running machine or lose all my data/email/documents/etc! Thanks.
