I love my iMac, but I feel it’s sluggish at times and I’m not sure if it’s all the clutter that has built up over the years, the amount of free disk space, or if it’s just as good as it’s going to get. So, I’m contemplating erasing my iMac and doing a clean install of Snow Leopard but I do have concerns.

Fist up is Time Machine.

Time MachineI’ve been running Apple’s Time Machine for years now and it’s backed up everything as far as I’m aware. I’ve done some spot checking and everything seems to be there, but it’s always a little nerve-racking as I don’t want to lose anything important. Have you found it dependable?

Also, how will it understand the new iMac configuration? Will the erased computer be seen as a second computer or will it try to intermingle the changes?

I guess the good news is that if Time Machine fails me for any reason, I also have BackBlaze.

Then there is partitioning.

Hard DriveBack in the day, I always partitioned my drives because that was the thing to do. But is it needed anymore? Does it really make a difference?

I’ve currently got 160gig hard drive and it’s split into 3 equal pieces. It seemed like a good idea at the time until iTunes grew to be 20gigs and iPhoto too. Now I have my system on one partition, iTunes on the second partition and iPhoto on the third. I can’t help but think that hurts performance.

My gut tells me to trust Time Machine, erase the computer, create no partitions, and just go for it.

What do you think? Is there a flaw in my logic?
