hard drives and computers I currently possessed:
1)iMac, 200Gb
2)Dell, 500Gb
3)My Book, 1Tb
4)Western Digital, 500Gb
5)dropbox, 9Gb + 3Gb + 2GB + 2Gb
Here's the plan:
1Tb MyBook will be my main active storage as it is now, as media, photos and works storage. 500Gb Westren Digital will be my backup for photos, and digital valuables. Dropbox synchronizing the current works before it is archived into my WD.
Sounds like a plan.
